Thank you for your prompt response and advice.
I regained some calmness and composure. Thank you very much.
Is it simply a malfunction if I can’t make a phone call even after returning to PureOS and inserting a SIM card?
Or maybe only the phone (calls) are turned off due to tampering with the firmware.
If so, is it possible to improve the situation?
I would be very happy if you could tell me how to initialize the firmware for Librem5 (pureos).
I searched for it using the above search, but I would like to know how to initialize the official firmware.
I look forward to your continued support.
