This happens in the prince comsie version and the other. I am making sure that it is the right stock firmware. any help is appreciated, thanks in advance.

I know this sounds weird but try flashing the At&t PK1 firmware and then after you should be able to go right back into odin and flash the PK1 firmware from T-Mobile.
EDIT: Just make sure you factory reset in recovery after you flash the at&t firmware.

Try using the latest official version of Odin. I have read that some people have had issues fishing stock firmware with the prince version of Odin.
