I have a problem with my Fairphone when I try to switch to Fairphone OS to Fairphone Open.
My phone is :
On the build FP2-gms-18.01.1 release-keys
On Android 6.0.1
The procedure I follow to update the OS is:
Open the file “fp2-sibon-18.01.1-ota-userdebug.zip” with Amaze
Click on the button “Restart”, then I have a pop-up with “Update of the Android system”
Then the phone restart and I have the green Android robot in black screen with the sentence “Installation of the update…”
After a few seconds the robot fall and I have a red exclamation point road sign and the sentence “Error!”
Then the phone restart on the Fairphone OS system like nothing happen.
Do you know what to do?
Sorry for my bad English, this is not my mother tongue, tell me if something is not clear.
