Hi,
my USB port stopped working so I changed the whole board where the usb-port is located. After the replacement I had no network after booting (no calls and no mobile data).
So I looked up this problem and realized that there are two different versions of this "USB-board" (K1 and K2). I had bout K1. Unfortunately I had threw away my original part directly after the replacement.
So I bought the version K2 and replaced it. But still no network.
Does anybody have an idea if there are more different versions of this board?
Thank you very much in advance
Alex
