I rooted my S4, MJ7, with that Chinese VRoot program, flashed the SuperUser program we all know and love, and downloaded ROM Manager from CWM. Then I tried to flash the latest CWM ROM with ROM Manager, and I got stuck in Odin for the better part of the day. What am I doing wrong? Well, that's not true. The ROM would just reboot into recovery and not do anything. I got stuck in Odin when I tried to flash TWRP Recovery to it. If it matters, I don't care if it trips the KNOX flag, but I do care if it bricks my phone.
