install fail with installer - fairphone 4

Lakotaubp

@3pticha Have you asked here https://t.me/ut_on_fp4 our FP4 group. From the above something is not unlocked, did you unlock bootloader before starting?

@Lakotaubp I did have unlock the bootloader, and when I had the following picture, it showed "DEVICE STATE - unlocked" like the picture

I will try the FP4 telegram channel

@3pticha
Try this adb command in fastboot mode : fastboot oem device-info.

I found it on a thread that could help you understand your issue, not exactly your problem, but critical partitions are something that can prevent some flashing in some cases apparently (like "manual" installs) : https://forum.fairphone.com/t/stuck-with-locked-critical-and-fpos/91940

I guess you could start by attempting to unlock critical partitions and then retry installing FPOS 11.

DO NOT relock the bootloader in any case.

Edit : Also found this thread with someone quite in your situation :

ERROR: The critical partitions are not unlocked.
Please refer to our support articles for help.

I don't think your bootloader partitions are unlocked, or at least not the critical directory.

I suggest you type the following 2 commands in the terminal:

fastboot flashing unlock
fastboot flashing unlock_critical

Then the installation process can begin.

The current Android ROM / Custom ROM must be version 11.

It turned out that I had missed the "fastboot flashing unlock_critical" part. Since then - and after repair by Fairphone - I've made some progress: Now the installation begins, but the UBports installer gets stuck at the "rebooting to fastbootd" step, while at the same time, the phone already displays the Fastbootd screen, with the menu offering "recovery," "reboot to system," "reboot to bootloader," and "advanced. But nothing happens

Maybe it's just waiting for you to click Continue?

@Moem I have no Continue button

@3pticha Try unplugging the phone and plug it back in.

@MrT10001 I made progress. Now it's stuck on "deleting logical partition" for an hour :

The phone display the fastbootd screen :
