Hi,
I have tried to downgrade using ODIN (from NC1 to MK2) and selected the (AP) and navigated to the .tar file and click start. In Odin i got failed message. I tried to restart but I'm stuck at a screen saying "firmware upgrade encountered an issue. please select recovery mode in kies and try again." I am using a AT&T I337 . All I'm seeing on my screen is "firmware upgrade encountered an issue. Please help
At the top left it says:
ODIN MODE
PRODUCT NAME: SGH-I337
CURRENT Binary : Samsung official
SYSTEM STATUS: Official
knox kernel lock 0x0
knox warranty 0x0
csd-conf-lsb 0x30
Go into download mode and start over from Step 1. But this time try a different USB port on your computer.
