A german manual how to install an /e/ ROM

Yes, I did. But then the device isn’t usable, because the errors mentioned several times in the forum already occur, e.g.

  1. Switching off the phone is no longer possible, because it is stuck in a boot loop and thus constantly reboots by itself: Shutting down (problem á la → S9/S9+)
  2. SIM card is not recognized
  3. SIM network “Not availabe”
  4. IMEI number unknown
  5. Modem is not recognized "Baseband version Unknown
