I refuse to install the one way Knox bootloader and use reversible work arounds (Agni or devil kernel or Dr. Ketan's WiFi bootloader patch) to get where I need to go.
If you have to put on the Knox bootloader my suggestion is to pull a nandroid in TWRP of what ever you are running now. Odin the whole Samsung stock UVCMK7 ROM then Odin TWRP 220.127.116.11 as found on the TWRP website. Then flash JMX2 (or restore your nandroid if you are already on JMX2).
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
