Those are like 300kb for abl.img and 3mb for xbl.im so I think those are not complete or full like the ones inside the phone right now ''abl_a'' and ''abl_b'' and sadly I can't dump them cuz there's no way to get root access.

Yeah but I'm saying this because I didn't find any fastboot commands using strings. I found here: https://github.com/Magpol/Android-Nokia3-HMD someone who extracted some hidden oem commands from the official firmware but that's another device. Idk if that's different from full OTA and Source code but we have both and I'm sure there's a way. I thought that passing through adb sideload would be enough

I used adb shell to check them inside my phone and they are different, abl_a - abl_b and xbl_a - xbl_b or maybe they are the same just for different partitions

same partitions, different slots ; see https://source.android.com/devices/tech/ota/ab for more info about A/B slots
anyways, i found nothing of interest within the two files

Looks like the only way is a signed vbmeta inside a signed OTA to shove it down the bootloader's throat and I think this should be a new universal way of at least getting root on any device with a public source code like this one. I insist on trying it but I have to learn more first

you seem to have either forgotten or ignored my first post @ https://www.hovatek.com/forum/thread-395...#pid215659
the bootloader expects a specific rom content, so creating a signed vbmeta and forcing it won't make any difference whatsoever, the device will get stuck in red state
