More information about wipe on Android

This information is for those who want to know more about wipe.

nonsense about WIPE

On the Internet, in particular sites on Android topics, you can find instructions on how to install firmware or obtain root rights. In these instructions they often write that you need to do a wipe and describe how to do it. It sounds something like this:

After flashing, do - wipe data, wipe cache, wipe dalvik cache, format data!

THIS IS COMPLETE BULLSHIT AND Nonsense!

Why? All because people don’t read the logs that Recovery produces and don’t know file structure Android, plus lack of knowledge of Linux commands.

When you perform wipe data/factory reset, the data section is erased, and in the data section there is a dalvik cache directory, and the cache section is also erased. Now you understand why you don’t need to do all these unnecessary manipulations! But you probably noticed that I didn’t say a word about format?

FORMAT or WIPE

WIPE and format are one and the same! How so? some Android literati might say! But like this, doing wipe or format is the same thing and it’s easy to check. In the /system/xbin or /system/bin section you will not find binary file format is only wipe, and in other Linux systems too. There is a reformatting to another file system, but that’s another story that has nothing to do with wipe.

About the subtleties of performing Wipe on Android

Many people are faced with the question of when to perform wipe? Before the firmware or after? It’s better to do this before flashing the firmware, since many firmwares may have a built-in function automatic reboot after installing the firmware! If the firmware contains files that are uploaded to the data section, then it’s worth checking how the system behaves; if it boots, it’s good; if not, then run wipe data.

About the subtleties of performing Wipe on Android 2

From personal observations I noticed next feature, in the popular custom firmware CyanogenMod there is a script that is executed during installation from under recovery menu. This script first backups system files ( system section) before flashing and restores after. Because of this script, errors can sometimes arise and wander, from firmware to the next firmware. Therefore, if you are a user of CyanogenMod firmware or you know that there is a script in the updater-script that performs this backup, then before installing the firmware it is better to also make a format system.

Hard Reset (hard reset, hard reboot) – Reboot the device, which restores the system to factory settings and removes all user information, including installed programs, contacts and SMS. Deleted information cannot be restored after this procedure, so it is recommended to save all important data before resetting.

Important! Data from memory cards, SIM cards, and the internal memory of the phone is not deleted (data from the internal memory and memory card can be deleted during a soft reset by selecting the appropriate menu item).

Why do you need Hard Reset?

Hard Reset is used as a last resort when errors and malfunctions occur in the device, when it is impossible to eliminate the failure by other methods. The fact is that the more complex the device, the greater the likelihood of various problems arising in it during operation: repeated installation and reinstallation of programs, cluttering of the device memory various files, etc. and it is usually impossible to determine the exact cause of the malfunction. The device may begin to operate unstably, slow down, or even not turn on at all. Hard Reset will return the device to its original state, canceling any actions with it.

Soft reset

If the smartphone/tablet boots up, you can reset the settings through the device menu. For this:

Go to the application menu...

…Settings…

...bookmark " Accounts" (or the item "Personal data") and select " Backup and reset" (or "Restore and reset")...

…Reset data (Reset settings)…

...Device reset...

…Erase/Delete everything

All. We are waiting for the device to reboot.

Hard reset

Not true

Often on the Internet, especially on sites dedicated to Android, there are guides on flashing firmware and obtaining root rights. These instructions say that you should reset the settings, describing it in the following way: wipe data, wipe cache, wipe dalvik cache, format data.

Therefore, if you decide to use CyanogenMod firmware, and also have an idea of ​​​​what an updater-script is, and that it contains the script that performs this backup, then before starting the firmware process you should perform format system. That's all.
