Hello,
it’s time to introduce myself to the forum. My name is Felicitas and I was working as Document- and Output-Management Specialist for a long time. As I was Support Manager at Xerox I’m also familiar with printer software and connectivity.
I started using electronical devices when the first Palm Pilot came into the market. My first smartphone was a Palm Centro, then all versions of the Palm Pre (exept the Veer, that was too small). WebOS was such a good one, Apple still copies its functionality. I switched then to Android with MotoG, OnePlus etc when my daughter pointed me to the good concept of Fairphone and here I am.
Due to my ludic drive my FP2 has to suffer 
I switched from the stock OS to FairphoneOpen, found that apps I like are missing and tried to go back. And this ended in disaster 
The screen turned to black, it’s still possible to enter fastboot mode, but the flash script hangs after verification. So I’m grateful that there are #fairphoneangels and will contact them for help.
