I have an SGH i777 Samsung S2 from AT&T and I have the unlock codes directly from them.
CASE: CM20150320_101115272
MOBILE: 6613804001
IMEI: 358055040069439
UNLOCK CODE: 79073737
We have reviewed your request and confirmed that the device may be unlocked.
Please allow 24 hours upon receipt of this notification to complete the unlock process.
To unlock your device, simply:
1. Power off the device, remove the battery, and insert a non-AT&T SIM card.
2. Re-insert the battery and power on the device with non-AT&T SIM.
3. The device displays” Enter the device unlock code.”
4. Enter the eight-digit unlock code once.
5. Press OK.
When I have tried to enter the Network unlock code it replies to me that it is unsuccessful. I have spoken to AT&T and to Samsung directly and neither are able to provide me with solutions. The phone has been working perfectly for the last 2 years and it only gave me this problem when I upgraded to a newer version and since then I can't use the phone application at all. It wiped all of the data on the phone but I can now access the other apps other than the phone. It should be noted that the SIM card is not from AT&T but from an international provider. I have also done a reset of the phone to the factory settings and that also didn't help.
I have also attached screenshots of the Kernel and phone version.
Does anyone have any solutions that they can offer with this?
