Recovery says there is no command on what to do. Android lies with an exclamation mark. What to do in such a situation

22.07.2015 21.07.2015 from wpandr_adm

If an android with an exclamation mark appears on the screen, this means that an unsuccessful experiment was carried out with the device’s software. This may have happened due to the installation of an unlicensed program or after switching from original firmware to custom firmware.

Hard reset

This action is carried out in the device’s engineering menu and allows you to return the smartphone or tablet to its original settings, which is very useful when the android lies with an exclamation mark. A special engineering menu is called up by pressing certain buttons, but there are some difficulties here. Models from different manufacturers have different key combinations. There is a certain sequence in calling the engineering menu.

The device must be turned off. It is best if the battery is fully charged. For most gadgets, the following combinations of buttons to open the menu are suitable:

1. The Volume Down key (or Volume Up key) is pressed and held together with the Power button.
2. Both sound control keys are pressed and held, and then the power key is pressed.
3. 3 buttons are held simultaneously: main screen, volume up and power.
4. The Home key is pressed together with the sound control key down, then the Power key is pressed. You must wait until the manufacturer's splash screen appears and release the Power button. After the robot image appears on the screen, you can release everything and wait for the engineering menu to appear.
5. Press and hold the power button for 2 seconds, then hold down the sound control keys and the power button and hold until a special menu appears.

After this, the gadget will either restart and return to factory settings on its own, or an engineering menu will appear. For your information, in this mode the touch screen does not work, all menu navigation is carried out using the sound control keys, and the selection button is the power key or the Home button. You must select “Wipe data/Factory reset”.

Several lines and a question will appear on the display (“Delete all data from your device?”). You must agree, after which the device’s memory will be cleared.

Reset on different devices

On smartphones and tablets manufactured by Samsung, the engineering menu is entered by pressing 3 buttons simultaneously: the gadget's main screen key, the volume up key and the power button. Resetting to the original settings is done using the Wipe data/Factory reset item and then rebooting.

HTC devices, when Android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and sound control buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, hold down the volume button and press the power key until an android robot appears on the screen. After it appears, you can release the buttons and press the volume down key again. A menu will appear in which you need to select “Restore original settings”.

On Acer smartphones, settings are reset by pressing and holding the volume up key and the power button. A menu will appear on the screen where you need to select Recovery Mode and press the volume down key. An android with an exclamation mark will appear. Now you need to press the power button. A menu will appear where you need to select Wipe data/Factory reset.

And on the tablets of this company, you need to move the screen lock lever to the left position, press and hold the power button and sound control keys. When the tablet starts to vibrate, you need to change the position of the screen lock lever several times until the words Erasing Userdata and Erasing Cache appear on the display. From this moment, the removal of settings will begin.

To return to factory settings, Asus devices must be switched to the engineering menu by pressing the volume down key and holding down the power button for 3 seconds.

After the time has passed, you can release the power button and hold the volume down key until a special menu appears. There you need to select Enter recovery mode, then Wipe data/Factory reset.

Device firmware

If a hard reset does not help, a complete software replacement is required. But there is a formality here: the firmware will only help if the “USB Debugging” function has been enabled in the device settings. This method is quite risky and the slightest violation of the instructions can lead to damage to the device.

Here it’s worth thinking about: should you try to restore the device yourself or trust the professionals? But if you decide to flash the gadget yourself, you should carefully study all the available information on this issue. Models from different manufacturers have significant differences and features regarding software changes.

In general, the process of replacing software looks like this: download the file with the firmware, study installation information, read reviews about this firmware version. Next, the file should be unpacked into the root directory of drive C and, if necessary, install drivers for the gadget. After this, the device must be turned off and using a key combination (usually a combination of the power button and volume up) switched to firmware mode. Then you should connect the device via cable to the computer and follow further instructions of the program. At the end of the process, you must perform a hard reset using the engineering menu.

What if the tablet does not turn on?

It happens that while playing games or working on the tablet, it stops working and does not turn on. The main reasons can be roughly divided into two categories: problems with the device’s hardware - these are malfunctions of the battery, connecting cables, boards, or some problems with the software - incompatibility of programs, the operating system crashed or was installed incorrectly after the update process.

Let's take a closer look at individual cases of tablet malfunctions.

Absolutely no signs of life
1. The simplest and most common reason is a completely discharged tablet battery. To check this version, turn it on and wait at least 10-15 minutes. Only after this the tablet will be able to accumulate the minimum amount of energy to turn on. Press and hold the power button on the device and wait for the screen to light up. If the screen turns on, check that the charger is working properly - take another one and follow the steps described above. The tablet turned on, but the charging process does not proceed, you need to find out why won't my tablet charge? .

2. If a child was playing with the tablet, he may have damaged it by hitting it on the floor or corner of furniture. Most likely, part of the display has been damaged, in which case it can be replaced. The tablet itself is in working condition. Screen damage is usually visible to the naked eye.

3. If the device has no mechanical damage, a rare case is that the video adapter has failed.

If you find such signs and there is a valid warranty on the device, run to the salon and wait for repairs; it is simply unreasonable to do repairs yourself.

The patient is neither alive nor dead

When the tablet turns on, but not completely, but freezes during the boot process (only the splash screen is on the screen), we are dealing with a software glitch.

The reasons may be the following:

1. Some programs or games are not installed correctly.
2. You forcibly terminated system processes, possibly through third-party software or task manager.

Procedure:

You can try to save the tablet by resetting the system to factory settings. It is best to find information about this on the Internet, because each device model has its own nuances. Or use the hard reset program. Using these instructions, you can reduce the procedure to the following:

1. Turn off the device.

2. Remove the SIM card and memory card.

3. Press the volume up key (on some models - down) and the button to turn on the tablet. Hold for about 10-12 seconds

4. If the tablet vibrates and a menu appears on the screen, you are on the right track. Select Settings, then Format Systems.

5. Reset the system - Reset Android.

6. The tablet will reboot with factory settings.

7. Try this scheme several times, it should work.

If unsuccessful, read the information on the topic “ How to unlock your tablet". Additionally, an excellent option for device resuscitation is flashing the tablet. In case of unsuccessful device firmware, good practical advice is given here.

Exclamation mark on a lying android


If an image of a lying green Android appears on the device screen, and there is an image of a red exclamation mark on it, you are in stock Recovery mode. There's nothing scary about it. Need to install the modified recovery ClockWorkMod Recovery. You got into it because you made a mistake when entering the combination to reset the settings, because each tablet model has its own combination. Press the power button and hold for a while until the device turns off, you can simply wait 3-5 minutes until the device finishes working on its own. As a last resort, you can do the flashing again.

What is Fastboot

The user can enter the mode Fastboot mode, in this case the android is also on the screen, but there is no exclamation mark. You need to use the volume buttons to get to the menu item Restart bootloader, use the power button to make a choice, sometimes this helps to revive the tablet.

Remember that each device model has its own “chips”. Some tablets easily reset their settings after pressing the home button while the Android is lying down, others only respond to simultaneously pressing the plus and minus buttons in the volume control for a long time.

Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are extremely popular. This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows Phone have a negligible presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system failures are a hallmark of any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that it is possible to do without such radical measures. After all, any Android gadget has Android System Recovery 3e. How to use it and what is it even? This is what we will talk about.

What kind of animal is this?

What does Android System Recovery 3e mean? This is a kind of BIOS of a mobile device. Any operating system has its own BIOS - a basic input/output system that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It is used to restore the functionality of a smartphone or tablet, apply critical updates or reset to factory settings. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English. Therefore, many people do not even know how to use recovery correctly.

That is why this article was written. Android System Recovery, the instructions for which are absolutely necessary, is a powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to waste money on specialists. Doing everything yourself is much easier and cheaper. We will analyze each item in the recovery menu and tell you everything we can about it. So let's begin.

How to enter recovery?

This depends on the specific device model. In some devices you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Older models with a mechanical Home button require pressing this button as well. Some devices require you to simultaneously press the power and volume buttons. There are also those who must hold down the power key and both volume buttons. This applies only to original devices from well-known manufacturers.

But there are also frankly “Chinese” gadgets with an incomprehensible operating system and “crooked” translation. Standard methods of logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the key combination you are looking for. But this option is not suitable for everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. The second option: find the desired combination by pressing all the buttons one by one. Now let's move on to the Android System Recovery 3e menu items.

Reboot system now

This menu item performs a complete reboot of the device. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this into account.

The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of a reboot: to allow the device to apply all the changes made. True, after some of them the smartphone may not boot at all. But that's a completely different story.

Apply Update from External Storage

This menu item allows you to apply the update that is located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this, you need to go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.

This paragraph has other subparagraphs that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, it immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required for them. If there are errors, then you do not need to install this firmware. That's the whole story.

Wipe Data. Factory Reset

This is a very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in the firmware. And this option allows you to perform this operation.

This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly states that it is imperative to use the Wipe Data & Factory Reset item before each firmware update of the device.

Wipe Cache Partition

Another useful command in Android System Recovery 3e. The recovery instructions say that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, then this one clears its cache. Namely, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for clearing the Android OS cache. And they work great.

It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even “cleaner,” which will have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.

Wipe Battery Stats

This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, into which the current state of the battery, its nominal capacity and other necessary parameters are recorded. By resetting the battery usage statistics, you can extend its life a little. And the new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory of the smartphone. This item allows you to clear a memory card or built-in memory, format it, or attach it as a drive directly from recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot your smartphone into the operating system. In order to mount the device's memory card as a drive, you need to select Mount USB Storage. As soon as the connection is established, the computer itself will install the necessary drivers for operation.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy the necessary files, and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.

Recovery errors

Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of the firmware or package. It can occur for several reasons: the firmware file is damaged, incorrect information in the binary file, or the firmware simply does not suit this device. But there is another option: before flashing the firmware, the device was not reset to factory settings. It’s good that they can be easily fixed in the same recovery. There are several ways to do this.

So, if the error occurs due to a broken firmware file, then you should download it, connect your smartphone to the computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. But the Android System Recovery 3e error “No command” is very rare. It only appears when the user tries to install an update via ADB. Usually this method doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.

Conclusion

So, let's summarize. We tried to describe the capabilities of Android System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.

The green android robot no longer greets you when you turn it on, but lies accompanied by an exclamation mark.
So, if you see this picture - the android is lying with an exclamation mark, then you can be congratulated, you have made your first unsuccessful experiment in interfering with the software of your device. What is it, and most importantly, what to do with it and how to restore the viability of the device? The search for answers to these questions must begin, first of all, by finding out the reason that led to this condition.
If you installed an incorrect program for Android, then after rebooting it will definitely please you with an image with an exclamation mark. There is only one way out - do a hardware reset by selecting Wipe data/factory reset in the engineering menu.

Entering the engineering menu if your Android is different on different Android smartphones, but the combination of the home, power and volume down keys is recognized as standard. On devices with a touch home button, a combination of the power and volume down keys is usually used. The key combination suitable for your device must be pressed with your fingers and held until the service menu appears on the screen.

After the inscriptions appear, you must select the appropriate item by moving up and down using the volume rockers. After selecting this item, several lines will appear on the device screen asking whether you agree to delete all data from your device. After selecting the yes line, the device memory will be completely cleared. The next step, if the device does not reboot automatically, select rebootsystemnow, which means rebooting the system. If after these operations your device has restored its functionality, then we can congratulate you. The only disadvantage of this method is the loss of all information - including contacts, SMS, photos and downloaded applications.

However, if you regularly synchronize your phone with Google and remember your account login and password, then your losses will be insignificant.
If the above method does not help, then you need to completely replace the software. There are two ways - the first is flashing the device using a USB cable and a computer, but it will only help you if the “usb debugging” function has been enabled in the device settings. The second way is to update the software using a flash card through the engineering menu. Both methods are very risky and the slightest violation of the instructions will lead to the complete destruction of the device. At this stage, you should think about whether to try to restore the device yourself or trust the professionals.

If you nevertheless decide to flash an Android with an exclamation mark yourself, then you should carefully study all the information provided on the Internet on this issue. Certain types of Android devices have significant differences and features regarding software changes. If we briefly and generally describe this process, it looks like this: you find the firmware file on the Internet, download it, simultaneously studying reviews about this version and installation information. After this, you decide on the method of performing the Android recovery procedure with an exclamation mark.

If you chose the method using a USB cable, then unpack the firmware files into the root directory of drive C on the computer, install drivers for your smartphone if necessary, turn off the phone, use the key combination (usually the combination power+volume up) to enter the phone into firmware mode, connect via a USB cable to the device and follow the further instructions of the program. At the end of the process, be sure to hard reset your device to default settings using the recovery menu.

If you decide to resort to the second method and restore the software using the device itself and a flash card, then the steps are as follows - upload the firmware file to the root directory, insert the flash card into the phone and launch it in recovery mode. After the engineering menu appears, select the recovery option using SD and wait. After finishing, you also need to reset your Android device.

There are quite a lot of problems associated with the operation of smartphones, tablets and other devices on which the Android system is installed. One of the most common and at the same time difficult problem is when a notification about the absence of a certain command is displayed on the device screen. What should the user do in such a situation?

Possible reasons

There can be quite a few reasons for this behavior of the device, which, however, does not complicate the process of solving it in any way.

A whole list of manipulations with the smartphone can act as factors contributing to the appearance of such an error. These include:

• Smartphone software or OS update that did not complete properly;
• during which problems occurred;
• Memory damage and other technical problems of the smartphone caused by falling, flooding and other typical incidents.

By itself, the cause of the breakdown is unlikely to help solve the problem, but it will help avoid the occurrence of similar problems in the future.

Solution

When the command error no android appears, what should the user do in such a situation? There is no need to find out the exact reason that led to such unpleasant consequences. It is enough just or, in some cases, to reflash the phone. The reset procedure is quite simple and is implemented very similarly in all modern devices. To do this you should:

1. When you turn on the smartphone, hold down the volume button, after which the menu will open
2. In it, select the WIPE data factory item, after which a reset will occur.
3. Sometimes, during the procedure, the smartphone may “ask” what to do with the user’s data. In most cases, they must be removed for the device to function correctly.

The flashing process is somewhat simpler than resetting, however, it also has its pitfalls. These include the need to fully charge the smartphone to avoid turning it off during manipulation. As a rule, updating the firmware is carried out using standard tools, supplied either with the product on a disk, or presented on the device manufacturer’s website.

If you have ever tried to flash an Android tablet yourself, you have probably come across the concept of “Recovery”. Today we will talk in detail about what this thing is, why it is needed at all, and of course, how to enter it.

What is Recovery

Recovery mode is a special boot mode for Android devices that allows you to completely reset the operating system settings, reflash the device, make a backup copy of the entire system or its individual partitions (as well as restore these partitions later) and some other things. At the same time, for this mode to work, the functionality of the operating system itself is completely optional. This is why the recovery menu is often accessed when the device no longer works in normal mode. And this is precisely why this mode is called “recovery” (from English “recovery”).

How to log into Recovery

To boot recovery, the device's hardware buttons are usually used. The most common combinations are:

However, some manufacturers may come up with “something like that,” so you have to search and experiment.

If everything is done correctly, a lying robot will appear on the device screen, on top of which there will be a menu with commands.

Another way to download recovery is through special applications, with which you can reboot your smartphone or tablet into recovery mode directly from the operating system itself (for example, Reboot menu). However, it is worth keeping in mind that these applications require availability to function.

Navigation in recovery mode is carried out mainly using the volume buttons, and selection using the power button. There are also devices in which only the volume down button is used for navigation, and the volume up button is used to confirm the choice.

To all of the above, it is necessary to add one important detail. The functionality of the recovery mode itself is by no means universal, and can differ quite significantly depending on the device. Particularly distinguished in this sense are “noname” tablets from China and some B-brands, whose recovery does not have any list of commands at all.

What to do if Android has an exclamation mark? In this article we will look at the main causes of device malfunction and ways to solve it.

The first version of the Android operating system appeared in 2008. The presence of a large number of functions, ease of use and low price compared to analogues made it accessible to a wide range of users. It is not surprising that issues related to long-term and uninterrupted operation of devices with this operating system are very relevant.

An icon on the screen in the form of an android with an exclamation mark indicates a malfunction in the device software. It may be associated either with the installation of an unlicensed program, or with a virus infection.

Typically, a user may encounter such a problem when turning on (rebooting) a smartphone or tablet. If this happened to you, what can you do?

The first thing they offer in such cases is this. To do this, you need to turn off the device, if necessary, charge it to 100% and turn it on in the developer menu mode. Since the key combination depends on the smartphone or tablet model, we recommend that you refer to the instructions. In the standard case, this can be done by simultaneously holding down the power, volume down and (or) Home buttons.

In some cases, after this action, the smartphone can return the factory settings automatically, but sometimes this must be done manually. Remember that in this state only the buttons work (you won’t be able to use the sensor). To move up and down menu items, you will have to use the volume keys. In the list, you need to select the “Wipe data/Factory reset” position with the Power or Home button, which means “delete data/reset settings” and confirm your choice in the next window that opens.

The main disadvantage of this action is that it will remove everything from your device that is not factory settings. And these are contacts, messages, photos, audio and video recordings and programs you installed. Therefore, if you do not want the safety of your data to depend entirely on one electronic device, make backup copies in advance.

If you are not sure that you can cope with this task yourself, it is better to contact a specialist, because any mistake can lead to catastrophic consequences.

If the “USB debugging” function is enabled in the Android settings, you can reflash the device.

Unpack the already downloaded folder with the program on drive C. Check for downloaded drivers for your smartphone and install if they are not there. Turn off the device, use a key combination to enter it into firmware mode and use a cord to connect it to the computer. Next, follow the instructions of the program.

If you have not connected the ability to debug your smartphone via USB cable, consider another option: reinstall the software using the device itself and a flash card. To do this, you will have to return to the previously described menu again, selecting the option to restore using SD.

In both options, at the end you will have to reset the system again to the original settings.

Let's summarize: Android lies with an exclamation mark - this is not an easy problem, but it can be solved. If you don't want to deal with it often, be careful about what you download to your device. Be sure to install it.

You can fix the problem either yourself or with the help of a specialist by resetting the settings or reinstalling the software.

Dear readers! If you have any questions or comments on the topic of the article, please leave them below.

It happens that when you turn on your smartphone or tablet, a sad picture appears: a green Android with an exclamation mark that appears directly from its “stomach”.

What is the problem?

If this happens, then it is definitely a software problem. A common failure of the operating system. Of course, in most cases, it was you who had a hand in this.
But this is a fairly popular and widespread problem, don’t worry, now we’ll try to solve everything on our own without any workshops or certified service centers.

How to fix

In fact, there are two very simple ways to solve this problem.
The first method is that you need to go into Recovery (a special mode for entering the bootloader, analogous to the BIOS). To do this, you need to turn off the device, and then hold down the Vol (-) and Power keys. In some cases, the combination may be different, for example, Vol(+)+Power, Vol(-)+Home+Power, Vol(+)+Home+Power and so on.

As soon as you enter Recovery mode, you need to select the Wipe data/factory reset option, but what you need is a factory reset, that is, a reset to factory settings. If you do wipe data specifically, then everything will be deleted.

The second method is to reflash your smartphone or tablet. It is more complicated, since here you will have to look for both the firmware and the flashing utility, unless, of course, you flash it via Recovery. You can even use the stock (standard) Recovery for flashing the firmware if you have the official firmware for the SDCard.

Nothing works out

If you cannot cope with the problem of the exclamation mark being displayed when turned on, then you can seek free help on the RuleSmart forum, in the Android first aid section. They will help you there, specialists respond daily to everyone, but describe the problem in detail, and also in a respectful tone; we hope there is no need to explain here?
