My coworker has a verizon S4 and has never rooted it or not it in any way. I have flashed with Odin on my S3 and S5, so I thought I might be able to help him. He took a recent OTA and the battery died in the middle. He had issues with it getting stuck during boot and having to turn it off and on until it finally loaded. I'm not sure what version he is on but he said the failed update happened 6 months ago. I can get it into download mode but it will no longer boot up and it has an unlocked logo on the screen that constantly reboots . Will these restore files work for him, or does he have something (bootloader?) locked? I know with my S5 that if I take a certain update I can no longer downgrade, but I still have access to a restore point for a newer veraion.
So basically he does not care about being rooted, will this restore work? Thanks!
