Help, I can't boot anymore a Fairphone 2

Hello every one.

So, I regularly test PostmarketOS on a Fairphone 2. Until now, it booted with no problem. But the last time I tested it, it failed to boot.

I use pmbootstrap. On the init, I choose this configuration:

  • Canal: Edge
  • Vendor: Fairphone
  • Device: fp2
  • Kernel: mainline
  • User interface: Phosh
  • All other options: The default

I flashed with 2 methods: From the TWRP recovery, with adb sideload, and from the bootloader with pmbootstrap flasher.

The result is the same: On boot, the Fairphone logo is shown then slowly fade to leave a black screen. Sometimes, I get vertical white lines. But nothing more.

I rebooted on TWRP and search for getting the last dmesg or the pstrore. With no success. But it's maybe because I use the mainline Kernel.

As I don't have an UART access, I don't know how to get more info on why the boot fail.

Do you have any idea ?

PureTryOut,

The wiki needs to be updated but the Fairphone 2 nowadays requires the user to flash lk2nd first before installing pmOS. See https://github.com/msm8916-mainline/lk2nd

Cyberfox,

Thanks for your reply.

I flashed lk2nd as described here: https://wiki.postmarketos.org/wiki/Fairphone_2_(fairphone-fp2)

Flashing lk2nd finished without error, but flashing rootfs on userdata never finished. No error, just never end.

Cyberfox,

Ah, sorry, it was just very slow. Wrinting rootfs seems to work but take a lot of time.

Cyberfox,

It worked. My phone boot now.

Thank you very much.

Cyberfox,

Strange, I chose "gnome-mobile" on the "pmbootrap init" and get Phosh. Same if I choose "gnome"
