When you mean "install a custom recovery via Odin", you meant to install something like TWRP to install the zip using recovery mode?
The phone keeps booting again and again, once the UI of the phone starts, I get a window of 1 min before the phone restarts again. I get a message saying "Process system isn't responding" before the phone restarts.
Yes grab Odin and TWRP/CWM (make sure you have the version to suit your fw 4.3 or 4.4)
Flash the recovery via PDA slot, put the fix on your SD Card via your PC then insert into phone, boot into recovery, flash the zip
and boom, you're fixed
