I have the Samsung Galaxy Mega 6.3 with U.S Cellular (SCH-R960) and I have run into some problems. What I did was try to root. Flashed CWM Recovery in Odin and when I tried to boot back up again, I was stuck in bootloop. So I tried to revert back to stock by flashing the stock firmware for my phone in Odin, the problem is, everytime I try and do that, I get this:
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> I9200XXUCNC2_I9200OLBCNC1_I9200XXUCNC2_HOME.tar.md 5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<ID:0/003> Odin v.3 engine (ID:3)..
<ID:0/003> File analysis..
<ID:0/003> Get PIT for mapping..
<ID:0/003> Firmware update start..
<ID:0/003> NAND Write Start!!
<ID:0/003> FAIL! (Auth)
<ID:0/003> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
Also, on the phone screen it says
SECURE CHECK FAIL: sbl1
I can boot into recovery and also into download mode. Although if I try to just boot the phone normal it just stays on the Samsung Galaxy Mega logo screen. I have tried sideloading a .zip and that also fails.
Does anyone have any idea of how to fix this? Any help would be greatly appreciated.
