My girlfriend has been having S4 issues in the past such as random restarts and application issues probably related to a ROM issue. Her phone IS rooted. While I was at work, she went to my floormate for advice and he, who also has an I337M S4, suggested she reflash a ROM. Things went well according to him (i.e. no ODIN issues) and I trust him since he has been messing with these things for a while; however, now her phone will not boot past the Samsung logo. It won't reliably go past the simple "Samsung Galaxy S4" white-and-black splash screen and when it does it fails to progress to actually being on. I CAN reliably get the phone into download mode and CAN flash ROMs using ODIN; however, I have no idea how to fix this issue. :/ I have access to any necessary S4 files (such as the PIT file) from my floormate.
Since I can't get anything more useful than download mode, here's the information from that:
Binary: Samsung Official
Knox Lock: 0x0
Knox Warranty Void: 0x1
Write Protection: Enable
MMC Burst Mode: Enable
I apologise if any of that isn't quite right as she has a crack in the top left of her phone that makes it very hard to read.
Thanks in advance,
