I have tried to install FP Open from source, following the steps from https://code.fairphone.com/projects/fp-osos/dev/fairphone-os-build-instructions.html. Syncing, compiling and flashing went just fine, however when running the phone I get the following issue : I can’t make calls (“Cellular Network not available”) and when accessing Settings > SIM Cards, the two sims slots show as empty (which is of course not the case physically speaking).
Amusingly, I am still able to send/receive SMS, and the top right icons indicates that mobile network is correctly found. I am even able to search for network operator, and in the About Phone > Status > Sim Status, I see that network connectivity seems just fine.
So, 2 questions arise : first, has anyone built and used successfully FP recently? second : any hints about the behaviour I am experienced?
Thanks a lot for any input.
