Creating and restoring firmware backup (nandroid) CWM Recovery allows you to create a backup copy of the device (not all sections), such a backup copy is called nandroid. CWM reserves the Boot, System, Data, Cache in the internal memory of the device and the. ".Androidsecure" on the device memory map, in the presence of other sections, for example, the Ext -section on the memory map, or the WebTop section (only on some Motorola devices) is created Their backup copy. Sections with firmware of the radio module, cameras (for some Samsung devices) and the bootloader are not reserved. If there are other sections on your device, it is better to clarify about them in the corresponding topic of the firmware. Not only the operating system is reserved, but all the settings and installed applications. Starting with the fifth version, CWM creates a backup in the TAR archive, which is very convenient, because It can be opened with an ordinary archiver, such as Winrar. In old versions of CWM, a backup is a copy of all sections in IMG images. The resulting backup can be restored only from the phone and only through CWM. The device should be installed by ClockworkMod Recovery.
Backup system: - Run CWM recovery
- Choose "Backup & restore"
- Choose "backup"
- Choose "YES"
- Select Reboot system now (reboot)
After that, a full backup will appear on the memory card in the clockworkmod / backup folder. The name of the backup copy includes the time and date of its creation, but the name can be given arbitrary, of course, in Latin letters without spaces.
Recovery: - We are entering CWM Recovery;
- Choose "backup & restore"
- Choose "restore"
- Select the previously saved backup. It should be on the memory card in the folder clockworkmod / backup.
- Confirm the recovery, select "YES". The confirmation item is usually not the first one on the list, this is normal
- At the end of the process, select "Reboot system now" (reboot).
The program for unpacking nandroid images as img
nandroid_recovery_unpack.unyaffs_fixed.zip(878.29 KB)
To work requires
Jdk. Using:
Install JDK, reboot. Create a folder on the disk in Latin letters without spaces, for example,
C: \ sss Put in this folder the image that needs to be unpacked, for example, system.img and two files from the attached archive: unyaffs.exe, cygwin1.dll. Now we drag the img file to exe. For some time the console window is lit, after it is closed in the same folder, we have the unpacked image. This is not always the case, so you have to act through the CMD panel:
Start \ Run \ cmd
cd c: \ sss press enter
unyaffs. exe system.img press enter
After in the same folder we have the unpacked image. The program does not know how to pack images back. We may need the program if we need to get some file from the firmware or from our backup copy, so as not to ask the users in the subject line and wait a whole day, it’s easier to install this program once.
Also images of nandroid (system and data (you first need to rename to system) in the img form can be unpacked and packed using the program
