Apres l’install de FairPhone OS, mon tel PF2 bug.
Dans le détail (sachant que j’ai suivis le tuto dans le liens 1) :
Dans un premier temps j’ai tenter de l’installer via ma debian (9). Cela n’a pas marché (le screept étant bloquer).

Je suis donc passé sur un iOS, et le script a fonctionner.
Sauf que au redémarage apres le protocle de démarage est rester bloquer 30mn sur ‘Android se mait a jour’.

J’ai redemarer le tel.

J’ai ensuite suivis le tuto dans le liens 2 depuis ma debian.
Cela a fonctioner sauf que au redémarge l’écrant ne s’allume plus.

Avez vous des pistes ?

When you tried to switch from Fairphone OS to Fairphone Open OS did you use the right file?
OTA Build switcher fp2-sibon-17.11.2-ota_from_gms-userdebug.zip

The going back guide links to quite an old FP OS version (It’s not even Android 6 yet). You probably have an FP2 with a new screen which needs an updated OS, so you’ll have to update the OS manually (works even with a black screen).

If you want to try again use the OTA switcher.

for information, I follow your device (in my debian 9):

I use ‘[Binary image] Fairphone OS 17.12.1 (Android 6.0)’.
But my terminal as freeze in
