Trying to flash an S9 using odin, not sure of the carrier as the phone is a friend's and he bought it second hand. Phone was continuing to loop and I couldn't proceed to homescreen no matter what recovery options I chose, prior to a flash. I was successful on getting a Canada XAC file I downloaded from sam mobile and installed using odin, but I continue to go in the same loop and can't make any progress. I get various errors in odin when attempting other firmwares. Any suggestions?
