Most often, the user is interested in how to flash an Android tablet for the following reasons:

  1. Updating Android helps keep the OS up to date, especially since updates are released infrequently;
  2. Expand the capabilities of the system;

  1. Turn off your tablet or smartphone;
  2. Turn it on by holding the Volume Up key and the Power button, sometimes you need to additionally press Home;
  3. Select " backup and restore";


Firmware via computer

In addition to the fact that the method is very convenient to use, sometimes it is simply necessary, since it is very difficult to flash a tablet if it does not turn on without a PC. Also, not all updates can be installed thanks to Recovery of the device itself.

There are a variety of ways to flash firmware via a PC, in particular when using Fastboot, but we will not consider this option in detail, since it is quite complicated to operate. Another convenient and simple way is to download a special program. Each tablet manufacturer has in its arsenal, on its website, an application that allows you to flash the device.

If for some reason the update fails, perhaps the device is not detected correctly, it is indicated that there are no available firmwares, then alternative options should be used.

How to flash a tablet via SD card?

To perform the procedure for installing firmware from a memory card, you must have some required tools: get root access, in our case Rashr app, a program for unlocking the bootloader and the actual firmware itself, which should be on the device.

First of all, you need to set the appropriate rights; to obtain root access there is a large number of programs, we will use one of the best - this Kingo Root. The application works on almost all tablets and smartphones. Download link https://www.kingoapp.com/android-root.htm. We will also need Bootloader Unlock, it exists for different device models.

Many smartphone holders and tablet computers At some point, they think about how to flash Android. The need to flash the device may arise due to problems with the operation of the gadget. It also makes sense to update Android in other cases, for example, to improve the functionality of the operating system and.

What to do before flashing your Android

An incorrect approach to the issue of flashing can lead to serious problems with the device, and therefore you need to prepare for this event. Before flashing Android you need to mandatory do the following:

  1. Before you start updating your operating system, make sure your device is fully charged. It is important to exclude the possibility of shutdown. You can connect the gadget to the charger during the procedure. If your tablet or smartphone turns off during a firmware update, system and data loss will occur.
  2. Check the operating system version android systems, which is relevant for your device, and also find out what firmware is currently installed. You can clarify this information in the device settings in the “About phone” section. Pay attention to the Android version, kernel version and build number.
  3. Now, based on this data, you need to find and download new firmware, which will fully match your smartphone or tablet computer model.

How to flash Android using a computer

It should be said that there are several ways to flash Android and in this article we will look at the most common ones. Let's start with flashing the gadget's firmware using a special program that is pre-installed on the computer. There are many applications that allow you to install a new version of the OS on your device, but we decided to focus on the Fastboot program, since it is safe, convenient and reliable, and is also best suited for the model that we will be flashing as an example. So, let's figure out how to reflash Android using Fastboot.

Note: the program for flashing Android should be selected based on the device from which manufacturer you are using. We recommend that you familiarize yourself with the following list of programs by manufacturer:

  1. Samsung - Odin
  2. Lenovo - Flash Tool
  3. HTC - Fastboot
  4. LG - KDZ Updater
  5. Sony - Flashboot
  6. Nexus - Fastboot.

First of all you need to download this application. There will be no problems finding Fastboot, you just need to know how to use it search engines, and today everyone can do this. Download the program and unpack it to the root of drive C so that the path to the file looks like this: C:\Android.


In the "Tools" folder there are necessary utilities, and in the “Driver” directory – drivers. Now you need to connect the device that you plan to reflash to the computer and install the driver. As a rule, the device automatically finds necessary drivers, however sometimes this does not happen. In this case, you need to open the website of the manufacturer of your smartphone or tablet and download software. Please ensure that the firmware you plan to download is suitable for your gadget model. The firmware must be downloaded in .zip format and placed in the Tools folder, which is located here: C:\Android.

Before flashing Android, you need to unlock the bootloader on your device. Process unlock bootloader will differ depending on specific model gadget. Open the Start menu on your computer, search bar enter the value “cmd” and select the cmd.exe program.


In the window command line type cd C:\Android\Tools. Confirm the command by clicking on Enter key, after which you will find yourself in the “Tools” directory.


Now you need to enter the command command the following type: fastboot devices.


If you were given a device code, then fastboot has identified your smartphone or tablet and you can start flashing the Android. If the message “waiting” appears in the window for device", you need to turn off the gadget and install the drivers. Now you need to enter the command for flashing: fastboot update firmware_file_name.zip After this, flashing will begin. Don't forget to restart your device after the operating system update is complete.

How to reflash Android via recovery

Another way to reflash Android is to use standard recovery or custom recovery (TWRP\CWM). We will explain what custom recovery is in more detail below. In short, these are unofficial firmwares. So, find the firmware that suits you on the Internet, download it and save it to the root file system your device.

Reboot your device into recovery mode. The process for entering this mode may vary depending on the specific tablet or smartphone model. Most often this is done by using a combination of the power button and the volume down key. After entering recovery mode using the “up” and “down” keys, you need to open the firmware and patch installation section and specify the firmware file previously downloaded from the Internet. As a rule, this item has the following name: “apply update from externel storage”, in TWRP – Install ZIP, in CWM – “apply update from sdcard”.

Following the instructions above, you will start the flashing, after which you need to reboot the gadget and reset the factory settings. To return to factory settings, go to the settings of your device and go to the “Privacy” section, then click on “Reset settings”. After this, you can check the functionality of the newly installed firmware.

How to flash Android via ROM Manager

ROM Manager designed to perform various tasks, for example, using this application you can create backup copy systems. By the way, we strongly recommend performing this procedure before flashing the firmware in order to restore the data later. ROM Manager can also be used to flash Android.

ROM Manager will not work if you are not rooted. Such rights can be obtained using special programs, for example, perfect following applications: Kingo Android ROOT, Unlock Root, Framaroot or Vroot ( detailed instructions Here). In addition, custom recovery must be installed. By the way, essentially using ROM Manager you flash the device via recovery, but unlike the previous option, this one involves working with a much more convenient and understandable interface.

So, find and download ROM program Manager. Now you need to download the appropriate firmware for your device. Open the ROM Manager utility and follow these steps:

1. Place the .zip archive of the firmware in the memory of your Android gadget.

2. In the ROM Manager menu, open the “Install ROM from SD card” section.


3. Find the archive with the firmware and click on it.


4. Next, select “Reboot and Install”. In order to be able to restore in the future operating system If such a need arises, you need to check the box next to “Save current ROM”.


5. In the next window, click “OK”, after which the smartphone or tablet will go into Recovery mode and the device will begin flashing.


What is custom Android firmware?

Firmware is called custom unofficial versions, that is, created from scratch, or modified. To install them, the receipt procedure is not always required. As you already understand, such firmware has nothing to do with official developers, but is created by enthusiasts with the goal of improving the OS by adding additional features and removing errors. At first glance, it may seem that custom firmware offers continuous advantages and is superior in everything official versions. However, not all so simple.

The fact is that often such firmware differs stable work and may cause problems with the device. That is why, before flashing your Android using custom firmware, you need to study the reviews of those who have already done it. Only after detailed study you can download the firmware and start installing it. As for installing unofficial firmware, the above options are quite suitable. In addition, detailed instructions for installing custom firmware are almost always available on the website where the firmware is located.

It should also be said that the unofficial flashing of Android suggests some differences depending on specific developer Therefore, the approach to the firmware will be different. If you plan to use special application to flash the device, we recommend that you familiarize yourself with the following list of programs by manufacturer:

  • Samsung - Odin
  • Lenovo - Flash Tool
  • HTC - Fastboot
  • LG - KDZ Updater
  • Sony - Flashboot
  • Nexus - Fastboot.

This is where we will end this article. We hope you now know how to flash Android. If you still have questions, ask them in the comments or in the “ask a specialist” section.

Finally we have free time in order to flash your Android smartphone. The manufacturer released a maximum of Android 4.4.2 for our Lenovo A328, we were not satisfied with this and, in the first days after purchase, we installed a custom version of the fifth Android on it. But we’re tired of this firmware too! Today we updated the Android firmware to version 6.01, installing the corresponding custom. And now we will tell you how I do this.

Firmware selection

On the Internet you can find a huge number of firmware for Android, some of them are official, and some are “customized”, that is, assembled by amateurs. We could have used the official one, but alas, the developer gave up on firmware updates. Not every firmware is suitable for your smartphone! You need to find special firmware. Enter the following phrase “Lenovo a328 firmware 4pda” into your favorite search engine, replacing the specified phone model with yours. There are a lot of different firmwares on w3bsit3-dns.com, for almost any phone. We liked it.

Preparing your smartphone for firmware

If you are planning to flash your device via an SD memory card, then you already have custom recovery installed.

We wrote an article on how to install custom recovery. (The link will open in a new contribution).

First of all, let’s read the instructions from the romodel. You can see it in the screenshot below.
Nothing complicated! We've taken enough screenshots to show you how easy it is. By the way, we wrote about how to take a screenshot in the article. Be sure to check out the bugs found in the firmware, screenshots, patches and other factors accompanying the post. Transfer everything to your computer necessary files, both from the device and from a flash drive (just in case), now create a folder on the memory card, for example “installos” and copy the firmware and necessary patches into it.

Don't forget to charge your smartphone! Will it be a shame if the battery runs out while updating the Android firmware? And the consequences, we think, will be quite dire.

Firmware via recovery

Getting into recovery is easy! To begin with, we turned off the smartphone, then pressed the power button, and as soon as the phone emitted a vibration signal, we additionally pressed both volume buttons. Those. Hold three buttons down at the same time. As the author of the firmware advises, the first thing we do is wipe. Follow the appropriate menu item.

Check the boxes for the required sections, which ones you need to look at in the instructions from the author, but basically they are the same. Once marked, move the slider to the right that says “Swipe to Wipe”. Wipe process not fast, it will take 10-15 minutes. Do not interrupt the wipe under any circumstances, be patient.

Now comes the fun part! We install the archive with the firmware that we previously threw on the flash drive. Let's go back to main screen, go to the “Install” item, look for it in the manager required archive, and feel free to move “Swipe”. The firmware will take a few minutes.

Wait until the firmware is installed, then use the “back” button to return to the file selection screen and flash the gaps (Google apps package). After the gaps, we rolled out all the necessary patches in the same way, with the exception of replacing the memory and radio. We remembered them later and installed them later. We will not describe the installation process, since it is no different from installing gaps. After installing the patches, feel free to click on “Reboot System”.

Primary Android setup

The launch will seem long. The first startup after the firmware may last longer than the firmware itself. Don't be alarmed, this is normal. In the described custom, during the first launch, one could see what the system was doing in this moment, and how long she still has left. Unfortunately, I was not able to take screenshots of the launch; apparently the corresponding service starts later. After launch, you will need to select a language, time zone, connect to the network, and also set up your Google account.

Of all the checkboxes suggested by Google, we left only one. It’s convenient for us when Google stores our contacts. We wrote more about this. In the card settings we indicated “Portable media”, because after the final installation and configuration we rolled out a memory substitution patch, which worked more correctly than the one built into the Roma interface.

The system started, and now we are the happy owners of cyan on Android 6.01, which we flashed from a memory card, spending about 30 minutes.

Finishing the Android setup

Before flashing the firmware, we backed up our applications using the program " Titanium Backup" Read about how to do this in the following articles. I'll tell you about restoring programs from a backup. “Titanium Backup” saved the applications we specified, along with the settings and data from these applications, into archives. We transferred the folder with these archives to the computer before we started flashing the smartphone. (The fact is that we formatted the memory card, although this is not necessary.) Now, after flashing the firmware, we reinstall “Titanium Backup”, for example with, although the version with is also suitable.

We drop the folder with backup applications onto the flash drive, enable root in the developer menu and specify the path to this folder in the “Titanium Backup” program. Read the article about how to get root this way. Next, we restore these applications in batch mode.

Applications restored in this way remember all my passwords, moreover, we are already authorized in them. We didn't even have to enter a password or secret phrase to log into our Bitcoin wallet, we just had to launch it.

The last step left is to replace the launcher with your favorite “ Smart Launcher Pro" and change the wallpaper. The rest of the launcher settings remained the same as we made them on the previous system, “Titanium Backup” carefully preserved them.

The Android operating system is ready to use! If you liked the article, subscribe to blog updates. The subscription blog is located on the right and below if you are on a computer, or below if you are on mobile version site.

The tablet began to freeze and slow down frequently, what should I do? Can I flash the tablet via a USB flash drive? Specialists involved in repairs often face similar questions. modern devices. Read more about this in the article:. Such situations arise due to the fact that the device is full of numerous applications, which, even after removal, leave small files on the device. You can radically get rid of the problem by flashing the device's firmware or reinstalling the operating system.

But how to do that? In general, the procedure seems quite easy and will require some effort from the user. To do this you need to have the following:

  • computer;
  • Internet access;
  • USB cable or flash drive.

From the last point it follows that there are several methods for flashing the device. And if with a USB cable you can independently guess how the procedure is performed (in fact, everything happens automatically thanks to the utility pre-installed on the computer), then how to flash a tablet via USB?

First of all, you should determine whether your device supports third party cards memory. If not, then the solution to the problem will be to reflash the gadget via a computer or the services of specialists.

Now the firmware file corresponding to both the brand of the tablet and its model is downloaded to the computer. Moreover, whether it will be an official assembly or a third-party one is up to the user to decide. In the first case, update support is assumed, that is, if any problems arise with the operation of the system, they are quickly resolved. In the second, there is a possibility that you will receive more additional features.

At the next stage, the firmware file is downloaded to a flash drive, which is then placed in the device. By clicking on the " Home", you need to hold down the power key at the same time. If the first one on a particular tablet is replaced by a sensor, then you need to press “ + » on the volume control key of the device. You must hold it until the brand name appears on the device screen. Android logo. After this, the system update will occur automatically.

Important: it is better to fully charge the battery in advance. If during the firmware the device unexpectedly sits down, then it will most likely fail completely.

In addition, one important detail should also be noted: tablets made in China, despite the fact that they use the same operating system, are usually not supported by developers. In other words, owners of such devices have to install updates themselves. As an example of how to flash a tablet via a flash drive, you can consider the Oyster T84.

How to flash an Oyster T84 tablet via a USB flash drive

First of all, you need to get root rights. ABOUT getting ROOT right read .

For this you can use special programs type Universal Androot and click on the " Root device" Then the ROM Manager utility is installed, in which it is installed through the appropriate section ClockworkMod.

The next step is to download the firmware file for the Oyster T84, after which it must be transferred to a USB flash drive. The tablet must be fully charged, otherwise what was mentioned above will happen. The ROM Manager is launched, in which the item “ Install ROM from SD card" At the end, the tablet reboots and the process is completed.

Conclusion

Flashing a tablet via a USB flash drive is practically no different from updating the system in other ways. In any case, you need to download only the appropriate model and brand of device, driver and firmware files, and also fully charge the device before starting.
