I got my smartphone back from repair (red led of death) yesterday. So I configured it and did the firmwareupgrade from XXJ... to XXDME6.
Now the SIM card is not recognized anymore
I read some threats about IMEI lost etc. and it seems to be the same here, isn't it?
So I contacted the Samsung support and they suggested to send it in for another 3-4 week repai, I suppose. Can I do anything to fix it without sending it in?
Thanks in advance!
