Hi,

did setup a gsm router/WiFi hotspot with my APU3D4.
Everything did work fine until I decided to update the firmware. (was obviously a bad decision)
Now I don't get the modem up and running because of

state: failed

failed reason: sim-missing

Any idea how to solve this problem ?

Thank you for any help

Kind Regards

Chris
