SIM suddenly stopped being recognized
Hi!
I had qtek (s200) prophet IPL 2.10.001 ,spl 2.20.0001 , GSM 2.47.21 and OS 2.20.7.36 . I upgrade with rom PL 2.10.001 ,spl 2.20.0001 , GSM 2.20.7.34 . After that my phone is not recognising sim. Message is there on the screen (invalid sim)
Then found out that the SIM was "missing or invalid"
Tried my SIM on a colleague's phone. It works.
Tried his SIM on my phone. Doesn't work
Tried soft reset, hard reset, flash a bunch of different rom, with and without the SIM inserted. With every different system I just get an "Invalid or missing SIM" message
Ah, also tried cleaning the contacts of the SIM holder in the phone, and even turning it on after half an hour in the fridge
Everything else seems to be working, it's just some part of the gsm system that doesn't work
Does anyone have other suggestions?
Thanks!!
