I was trying to install a GSI image, which failed. So I flashed the stock image using the upper dump from following instruction: TWRP installable stock firmware packages for Fairphone 3
It worked after chaning the filesystem from the system partition and then it booted successfully.
However my sim cards are not recognised anymore. I tried flashing the modem.img from the A_0110 dump, but did’nt solve the problem.
Any ideas what I can do? I’m not a complete expert in this topic.
