I get the feeling I'm probably just doing something wrong, not flashing something, etc etc.
Managed to root my MF3, install SafeStrap, and create a new rom slot.
All that was pretty easy, but I'm stuck trying to install a rom to the new slot.
I'm trying to install Vision X:
I've ROM'ed phones in the past, flashed modems and GAPS, things like that. What I've been doing:
1) Flash Vision X Rom
2) Flash SafeStrap MF3 Kernal
3) Flash LokiDoki (Found here from Vision X: http://www.androidrootz.com/2013/10/...gt-i9505t.html)
After this process, I reboot to System, but the phone just begins to boot loop =/
Obviously I can just jump back to stock, which is fully functional. If someone could be so kind as to point out my (presumably) really silly mistake, I would be grateful!
