[HELP] Google Pixel 5 bricked (LineageOS for microG 18.1)?

[Michu_z]

Hi All,

After several years (since 2006) of playing with flashing and rooting the hardware, the day has finally come (I still hope not ...) - I broke my smartphone.

Don't ask me why it happened - I think I was rocking in the clouds by turning off USB debugging while I was still getting my stuff back from backups... Maybe I clicked this option by accident. But one by one:
1. I have downgraded the LineageOS for microG 18.1 ROM to the April 11 version (the newer one had huge connectivity problems :[).
2. Everything worked fine again, unfortunately I have restored too many files (some system files) using my root backup and after rebooting I have bootloop.

The above would not be a problem, but:
* USB debugging is disabled (I don't know if there is a hack method on Pixel 5 to enable it from PC (I'm using Linux)). Flashing recovery seems unavailable (Writing 'recovery' FAILED (remote: 'No such file or directory')), the same with adb sideload commands.
* adb shell is unavailable (I tried to send a ROM image file to the device) due to lack of any trusted device on Pixel 5.
(db: error: failed to get feature set: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.)
adb kill-server/start-server and deleting my Linux adbkey doesn't work of course.

I can only add that I have root access and an unlocked bootloader, but I don't know if I can do anything on this basis.

Is there any magician on the forum who has an idea for my brick with bootlooping screen?

Maybe this can work for you? >> Deuces Flashing Script
It should work with any google factory image as stated in the post, don't download the wrong factory image tho.

Goodluck.

Thank you very much! I have only recently been with Pixel and did not know about the existence of this script.

Interestingly, on my first try on Pixel 5 the script crashed, it requires fastbootd instead of the fastboot standard:
system
Sending 'system_b' (23660 KB) OKAY [ 0.700s]
Writing 'system_b' FAILED (remote: 'Partition should be flashed in fastbootd')

as a result, the system did not rise.

Quickly switched to recovery and then fastbootd on the second attempt was successful.

No need for a magician then I guess, haha.
Glad it worked out mate, don't brick your phone again. I think pixel phones are one of the hardest to fix.
