GSM-Forum - View Single Post - SM-N900p unlock success but Invalid SIM

Stunman112 · 07-14-2016, 01:06

So after i flashed the MJ4 Modem file i got no more "Invalid SIM" message. Thats good, and for the GCF settings they were already enabled. The menu was a lot different then the way you said but all in all it doesn't show "Invalid SIM" anymore. I am able to select GSM or automatic settings. I don't have a active SIM to test it with but shouldn't the SIM's carrier name show up in settings? I have a AT&T SIM and a Metro SIM i tried and neither will show the carrier name in settings. Is there a way to tell if the unlock was a success besides an active SIM? I have heard i should re-do the unlock too after flashing the modem. Also, KNOX remained 0x0.

Thanks for you guys help.
