Is that really normal with a rooted device that amaze can’t edit or create file in the rooted folder when it got root acces?

I don’t think that’s normal, but I’m on LineageOS right now.

@frederiiiic

number build is : “FP2-userdebug 6.0.1 FP2 fp2-sibon-18.03.01 release-keys”

Ok, that’s Fairphone Open OS, allright .

i don’t remember exactly how i installed fairphone Open OS, but i think it was with the update app

Sounds likely … the Fairphone 2 comes with Fairphone OS preinstalled, and the Updater App has a way to switch over to Fairphone Open OS.
I’ve never done that myself in this way, but I would assume that the Updater App uses the respective switcher file for that. Should work, but has been seen to go wrong sometimes, too, sh*t happens.

If you have important data on the phone, back that up to a safe place outside the phone, wipe the phone completely and install from scratch …

FP2 cannot install Fairphone Open 17.10.1

You could try the TWRP way to completely wipe the phone and make a clean install from scratch … I found that to be very helpful and reliable when trying out different OSes. Attention! This will remove the installed OS and all your data from the phone (which most things labeled “factory reset” on the Fairphone 2 will not completely do). Get TWRP running as recovery (skip this step if you have the latest version running already): Download the latest TWRP image from the “Download Links” sectio…

… at least that would make sure no other problem of the OS intervenes and we could cleanly work further from there.
