Hi !
Having recently received my FP5 with /e/OS, I’ve been playing around with it a bit and, above all, I wanted to transfer my data from my old phone.
To do this I use Neo Backup.
It needs root rights to work properly. So I followed the official procedure for unlocking the bootloader, then the instructions in the following post to install Magisk.
Out of ignorance of the risks, I wanted to relock the boot … without un-root. So, when I rebooted, I got a warning message saying that the system had been altered and that it would not boot normaly again.
Since then it has been stuck on the bootloader.
Hi,
Sorry for the delay.
Unfortunatly i can’t change the active slot :
$ fastboot --set-active=b
Setting current slot to ‘b’ FAILED (remote: ‘Slot Change is not allowed in Lock State’)
fastboot: error: Command failed
I found a similar case for an FP4 that ended up being supported by Fairphone.
I’m going to ask Murena for support and if they don’t have a solution for me, I’ll contact Fairphone directly.
That (blocked boot because of corrupted device) is exactly what I was running into → flashed /e/OS, installed Magisk, installed the magisk-patched boot.img and then wanted to try to lock the bootloader and got stuck - but I just locked with the first command and not with lock_critical as well, so there might be a difference…
In the end I could re-unlock (“fastboot flash unlock” didn’t show me the failed command like you posted), re-flash boot.img, etc. and work again with that Fairphone.
I would at least expect that “fastboot flash unlock” would work… Why shouldn’t it?
(I am wondering, why we users cannot have secure-boot and root access at the same time… just a little sick about how mobile devices work nowadays)
A few news items.
Thanks to Murena’s support and for a very modest fee (€50 including postage), I’ve got a working phone again. I don’t know what they did to get it working again, but everything is OK.
I went through the rooting process again and everything went well!
For the record, I did receive confirmation from Murena support that the phone could not be repaired by myself. So the return to the after-sales service was essential.
