Android Q beta2 Rollback

[nick w]

Hi all
Does anyone know the best way to roll back from updating to AndroidQ?
I have issues (android auto, casting etc) so would like to roll back to the lastest stable release

I am having a right pain restoring to to anything at the moment

Thanks

Yeah you can either use the "flash-all.bat" file that comes in the android p stock image zip or fastboot boot twrp.img and once booted into twrp just restore a backup. But you'll need to create a folder on you sdcard called TWRP. Then put a backup in it. I've even booted twrp then flashed pixel dust. It's not as critical as it was years ago when once you went up bootloader then downgraded which would cause bricking. At least I haven't run into any issues. Just make sure you turn off any lock screens and have "USB debugging" enabled.

If you are enrolled in the beta, just opt out on the website where you opted in. You'll get an OTA, which will wipe your device, so back up first. Just did this last night. Couldn't have gone any more smoothly.

For some odd reason when I rolled back my battery refuses to charge up to 100% any one else having this issue?

You have to have your phone unlocked... Yes, you will lose everything from internal memory, but can restore all your apps and settings.

I made this path twice, on beta 1 and now on beta 2.

First, make sure you have twrp. Back up on twrp everything but you will need only the data partition. Also don't forget to backup your internal memory (different from the data partition).

After that, just flash normally the last factory image from Pie, or at least the same version that you have on your nandroid backup.

After finish the installation, install again twrp. Go into twrp and restore ONLY the data partition!!! You can also restore the boot if you like (if you had magisk installed for instance). This worked flawless with me.

I repeat, no use if you try to restore ALL partitions on twrp!! At least with me, twrp would just reboot in the middle of restoring the system partition (no idea why that happened on beta 1 and now on 2). Second, the same if you try to flash factory image without the -w (without wiping internal memory), it just reboot every time it tries to enter android.

This is a bug that was fixed in Q. You can alternatively fix it in pie by flashing a kernel that has Q patches merged in.
