Please help. Galaxy s4 AT&T stuck in Odin.

[iHaCkurAnDrOiD49]

A customer/friend tried to get twrp on his s4, now it only boots into Odin mode and says:

Could not do normal boot
Odin mode
Product name:sgh-i337
Current binary:Samsung official
System status: official
Knox kernl lock:0x0
Knox warrenty void:0x0
Csb-config-lsb:0x30
Write protection:enable
Ewmc burst mode:enable

It was rooted, but the android version and build number is unknown. I typically do physical repairs, not software related repairs. Can anyone help me? Or even point me in the direction to get this fixed?

Xda, look there. There are stock odin roms you can use to recover. If this was bootloader unlocked beware what android version you flash.
