Hello, I was trying to install a custom recovery, and things went wrong somehow. The phone will usually go to a screen saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." When I try the emergency recovery in Kies, it fails almost every time. I took the advice of other on various forums, and tried to install the firmware with ODIN. But it fails, every time, saying "Fail (Auth)". Is there anything else I can do and help would be GREATLY appreciated. I am using the AT&T SGH-I337 phone.
