Backup boot, system, custpack via CWM recovery

1. Download backup_by_Gulyuk.zip and put it on the microSD card (do not unzip).
2. Ensure that you have at least 216 MB of free space on the microSD card.
3. Enter ClockworkMod Recovery as described here.
4. Select "install zip from sdcard" in the menu, then select the backup_by_Gulyuk.zip file. Wait for several minutes while the backup script works.
5. Select "reboot system now" to exit from recovery.

The backup script should create the firmware directory on the microSD card (seen as /sdcard/firmware from the phone) with these files:

• boot.img — dump of the boot partition (kernel and initramfs);
• sys.img — dump of the system partition in yaffs2 format;
• cus.img — dump of the custpack partition in yaffs2 format.

Restore boot, system, custpack via CWM recovery

1. Download restore_by_Gulyuk.zip and put it on the microSD card (do not unzip).
2. Ensure that you have the firmware directory on your microSD card with valid firmware image files (boot.img, sys.img,cus.img).
3. Enter ClockworkMod Recovery as described here.
4. Select "install zip from sdcard" in the menu, then select the restore_by_Gulyuk.zip file. Wait for several minutes while the restore script works.
5. Select "reboot system now" to exit from recovery.

The restore operation erases all user data from the phone (unlike the nandroid restore, which can restore userdata from the backup).
