So I tried to use firewater's S-OFF and it failed saying there's nothing I can do to fix it, blah blah blah... well I went into HBOOT to check the OS version and it's just blank? I'm not really sure what caused it or anything and I'm not sure if it's important to fix. It works just fine though.
Running Stock Sense 6, Rooted, TWRP and unlocked.
Edit: Sorry, I just realized I posted this in the wrong section... my bad. :\
