I'm having an extremely odd problem with a second hand phone I recently bought.
I first turned it on (stock fw) the bootloader indicated a 9305. However the sticker behind the phone indicates a 9300.
I flashed TWRP & cyanogen nightly without any problem.
I then noticed that the IMEIs are different (between sticker & *#06#), both of them being valid on an online IMEI checker (9300 and 9305).
Now I also get random reboots and sometimes a "baseband unknown" problem.
Just to be sure... could you confirm that cyanogenmod wouldn't indicate an LTE connection if the HW wasn't actually LTE capable? I'm very confused...
