I was able to fix it by using Odin and flashing the stock Rogers ROM .tar file. That fixed everything and stock was running fine all night with no reboots or issues. This morning I did a fresh download of the ROM rebooted to TWRP wiped cache *2, Formatted system *2 and factory reset *2, installed the ROM and rebooted. I should mention I am using TWRP version 18.104.22.168. The ROM usually loads for about 1-2 mins then reboots and repeats over and over. Does anyone have any ideas? I've even formatted the internal and external storage. I did notice there is one folder on my internal SD card that I cannot seem to remove called Z and has a LMT.apk and another folder with wallpapers in it. I cannot delete or remove this folder as it keeps saying the folder is write protected. Even after formatting the internal storage that folder remains which makes me wonder if my SD card is screwed up.
Sorry for the long post but I am running out of ideas and don't want to be stuck on Stock. What could be causing this? I've tried flashing a new kernel from TWRP and still the same results, I've even tried different ROMs just in case but still the same results. The only thing that seemed to work so far was the stock ROM via Odin.
Do you have SD Card adapter for the computer? If so, try removing the card from the phone, then plug it into the computer and formatting it that way. For the ROM boot loop issue, try flashing a stock ROM using ODIN, then using whatever method you like the most to flash the ROM you want to use.
