TWRP Backup Section II​

Important Notes:

These Instructions got originally written for my Google sheet and my own backups. However, they can be used with every TWRP Backup that contains a System Image that has never been mounted as read/write, the corresponding Boot Image and the corresponding Stock Recovery.

If a backup lacks the corresponding Stock Recovery you might need to flash it manually.

On the other hand, if you want to keep TWRP you mustn't restore "Recovery".

Be aware that it's possible to flash OTAs with TWRP if you are at least on firmware 3.x and using at least the official TWRP version 3.1.0-0. For more information read the OTA section.

If you can't fulfill these two requirements you need to restore the Stock Recovery and an untouched System Image (e.g. with the instructions in this post) for being able to receive/install OTAs. Otherwise any Update will fail since Google introduced Block-based OTAs with android 5.

Instructions:

Be aware that you need an external SD card for your phone. In contrast to the RUU method, there is no size limit for the card if you want to restore a Backup.

There is no need to lock or re-lock the bootloader if you use this method.

If you follow my instructions all your personal data will be erased so backup everything that is important (e.g. contacts, messages, pictures, etc.)!

Format your SD card with a PC to exfat and put it back into your phone.

Boot to TWRP.

Create a backup on your external SD card.

Backing up "Boot" is more than enough. We only want TWRP to create the needed directories on your SD card.

Download the correct backup for your firmware version.

Boot to Download Mode. It is stated in the line with "OS" at the beginning. The "firmware version" in "settings>about>software information>more" is only the base of the (custom) rom you are running.

In contrast to RUUs, you mustn't use TWRP backups that are newer than your current firmware.

Unzip the downloaded backup.

Copy the unzipped backup folder to "TWRP/BACKUPS/<YourSerialnumber>/"on your SD card.

Sometimes this is only possible if the SD card is directly connected to your PC and not put into your phone. I don't know why some M9s refuse the copy process.

I recommend wiping everything except "Micro SDcard", "USB-OTG" and "SD-Ext".

Check the "Mount system as read-only" box in the Mount menu.

Restore the backup.

Boot to system (ignore the warning that no OS is installed). This process may actually take a while!

Congrats! Your system is now stock and able to receive and install official OTAs, again.

Sidenote: The SKU is part of your firmware version and located between the second and the third dot. Example: If 3.35.401.12 is your current firmware then you need to look for Backups with SKU 401.
