Installation instructions:

You can use either fastboot flasher or adb sideload to install this ROM.

If you are using adb sideload, we recommend AEX recovery over TWRP, since TWRP doesn't work fully on A12 yet.

Steps to follow for Twelve with GApps Build:

1. fastboot flash recovery recovery.img ( only if coming from other ROM/ Stock OOS )

2. Reboot to recovery

3. Format data/factory reset

4. adb sideload ROM.zip

5. Reboot to system

Steps to Follow for Twelve ( Vanilla Build ):

1. fastboot flash recovery recovery.img ( only if coming from other ROM/ Stock OOS )
2. Reboot to recovery

3. Format data/factory reset

4. adb sideload ROM.zip

5. reboot back to Recovery ( and not in ROM )

6. adb sideload the GApps package / Micro G package

7. reboot to system

8. it will throw error and ask for format ! Do the Format once!

9. reboot !

You can either sideload magisk zip or can patch boot img. Recommended to root only after the first boot.
