Stuck in boot screen & could not display the recovery system menu

[kwiky]

Hi everyone,

My fairphone 2 doesn’t boot anymore and get stuck on the black screen with the “Fairphone” logo.

• I have tried to wait around an hour but it doesn’t go further and keep stuck on this screen.
• I have tried to reset it with the system recovery menu (Power & Vol+) but the screen with the open robot and the line “No command” appears during some milliseconds, immediately restart and retry to display the same system recovery screen indefinitely.

What do you suggest ?

Welcome to our community forum.

Most likely a manual installation of Fairphone OS is what you should try now. Just make sure to check first if any of the buttons seem stuck (i.e. permanently pressed), especially the volume button.

Hi there and welcome to the community!
Does the led flash blue? In this case you are in fastboot mode.
Does taking the battery away and back in change anything?

Once you are on the no command screen, you have to press the power button and shortly the volume up (or down. I think up) button to access recovery. But the fact that it restarts isn’t really normal.

You could take the cover off to check that one of the buttons isn’t stuck for a reason or another.

Whoops, I see that @urs_lesse was slightly faster than me…

Thanks guys

With your help, this is what i have tried :

• I have checked the volume buttons but it don’t think that they are locked…
• I have booted in fastboot mode : the led slowly blinks blue (3s on & 1s off)
• I have donwloaded Fairphone OS 19.11.2 launched the flash-for-mac.command script (i have a mac) and the script see the fairphone & starts uploading system files on it
• At the end, i have pressed enter & the fairphone restarts
• The fairphone seems to be stuck (since 5 minutes) in the same situation than before (Fairphone logo + powered by Android)

I will wait longer (30, 40 minutes) & retry to boot with the system recovery menu…

After an hour stuck, i have tried to restart in recovery mode but i have the same issue :

Perhaps you could try to flash TWRP. Or you don’t even need flashing, see #twrpwoflashing.

Today i have tried TWRP, i have succeeded to boot in

I have tried to do a factory reset but it don’t seems to work…
Do i need to do something before try the factory reset ? Mounting some partition ?

Do you have an idea of what could be my next attempt ?

[kwiky]

Maybe it’s a clue, but i don’t be able to mount anything with TWRP…

EDIT: After made some search, it’s maybe an encryption issue.

[Alex.A]

What TWRP version did you install?
Foe encryption-TWRP related, check this topic (don’t know if it can help you though):

TWRP data decryption support for FP2

This is a wiki post. Everyone can improve it, by clicking the green pencil above. Since each new TWRP release seems to bring its own flood of decryption threads, I realized a wiki that reunites all the compatibility info between TWRP and Android encryption was somewhat needed. Here’s a quickstart that can be improved over time by everyone. Please, avoid ranting over TWRP. Always remember that TWRP is a community project, encryption is a complex matter and its support in TWRP is not even gua…

@kwiky

After made some search, it’s maybe an encryption issue.

Only the data partition gets encrypted, so at least the other partitions should get mounted without all those error messages.
I have never seen a TWRP behaviour like this, I don’t know what went wrong there.

@Alex.A

What TWRP version did you install?

Question seconded.

[kwiky]

That was twrp-3.4.0-0-FP2.img so version 3.4.0

I don’t know what to do

[Alex.A]

I don’t have much of a clue either. Perhaps you could try installing an older TWRP version. I thought I had seen somewhere that 3.4.0-0 could.be slightly buggy (though I doubt it will change anything). But then, there would be decryption issues as well…
Otherwise you could also try installing another OS like Lineage or /e/. But again I don’t think this is the problem.
A very wild guess: a problem with the core module. Do you have a way of trying another core module (by contacting a #fairphoneangel)? Can you do a nandroid backup through TWRP, that could then be restored on another core module?

I would also try unrelated things like starting without any modules, you never know.

Maybe this works:

[FIXED] Unable to mount /data or /system error

I just tried to repair file system but got ERROR: 16 from e2fsck
