FP4 bootloop after restoring factory image

Hi !

Today, after playing with my custom LOS 18 build for quite some time (a bit more than a month), I thought I’d give a try to latest fairphone OS.
I followed the official procedure , everything went fine except… my device won’t boot :smiley:
It will actually vibrate at “FAIRPHONE” logo and then reboot all over again for a couple of times until it finally gives up and reboots to bootloader.

I tried rerunning the flash script again, with no success. I mean the flashing process go through with no error but same outcome. Anyone would have an idea how to overcome ? Bootloader is of course still unlocked.

@Aaanze
Did you wipe data / factory reset afterwards or is that automatically done by the flash script?
Are you able to boot to stock recovery?

I’m curious because I want to experiment with LOS but it’s important to be able to go back to stock.

Well I tried to but I can’t access recovery, it will automatically fall back to bootloader.
And it IS supposedly done automatically by the script.

Hm that’s weird. Have you tried if at least going back to the LOS build is working?

maybe wrong avb_custom_key

that’s plan b haha, I’d rather see if anyone has an idea !

Edit:
Nope not possible, tried to flash LOS recovery, which succeded but still couldn’t boot to recovery.
Tried to force boot on it with

fastboot boot recovery.img

Got “Failed to load/authenticate boot image: Load Error”

What would that mean and what should I do about it ? :smiley:

Edit 2: Now that I look closer to the flashing logs, even though there is not error, I do get some message between almost each step saying:

target report max download size of 805306368 bytes

but at not point do I get any “failed” nor “warning”.

You can read something about avb_custom_key here:
https://android.googlesource.com/platform/external/avb/+/pie-release/README.md

Not sure if this could be the issue. But

Sounds like it’s failing to verify the signature.

Did you do the “fastboot flashing unlock_critical” step when you originally unlocked the bootloader? I read that this step was only added later.

That is completly normal.

You might be on to something. Indeed I did NOT do this when I initially unlocked the bootloader (because like you said it was not in the guide at that time), therefore I did it just before running the flashing script because I had an error saying that critical could not be overwritten or something.
And now that I think about it… I did not start a fresh setup of the phone after doing so, I jumped right to the flashing steps.
Did I brick my phone ? :smiley:

Hm but if unlock_critical then succeeded and all is now unlocked I don’t know why it should be bricked.

Maybe the output from

fastboot getvar all

can give us a clue?
