I need help installing avbroot on oxygenos 11 android oneplus 8 pro stock firmware

Please post more details. What issues are you running into?

[floean]

I get these files OxygenOS 11.0.11.11 I flash them I try to lock the bootloader, but the recovery does not boot, reboots back to fastboot

[chenxiaolong]

Just to confirm: before you tried flashing the patched file, did you first flash the original zip while the bootloader was still unlocked?

I didn't document that in the README (I should), but the instructions assume that the device is already running the ROM.

[floean]

Yes, the ROM was already installed original

If that's the case, I'm really not sure why it wouldn't be able to boot into recovery.

Can you try one last thing: try patching the OTA with --rootless and remove the --magisk <apk file> option. This will create an unrooted OTA, but it'll help test if Magisk is potentially the issue. If that's also unable to boot into recovery, then I'm out of ideas.

this happens when fastboot flash recovery recovery.img because of this does not start recovery

Just to add to this, I flashed Nameless AOSP on my Oneplus 8T a couple months back and it seems to work perfectly till the time the bootloader is unlocked. So I'm guessing the issue was solved with the later versions of avbroot

Hi, bro. What was the Android version and OS version of your OnePlus 8T before upgrading to Nameless AOSP? I saw in #212 that OnePlus only supports avb_custom_key before Android 12. So I'm a little worried whether downgrading the system can make avb_custom_key work properly.

Afaik I was on OOS11. Then I used wishmasterflo's firmware flasher to flash OOS13.1 firmware. I don't remember if I flashed the avb key before flashing the firmware or not though. Nameless is based on Android 14.

Okay, thanks. I'll try it out over the weekend
