Thanks :) and I've been reading up on safestrap. Can you flash custom roms using that on another system??
Even if you safestrap you can't flash kernals(so you can't have anything like CM11, PAC, etc) only Stock based roms will work.
K, you need to upgrade your firmware or everything is just gonna bootloop on you.
either run a windows environment so you can run a RUU or
