Hmmm, I didn't rename the .zip just left it as it was and all appeared to go well...
Got bored with waiting for it to load and tried to reset it - same colourful dell logo and the waiting game begins again... Surely something should happen. It just keeps micro-bursting the vibration every now and again?!?!
EDIT: Ok so the phone is not booting... just stays at the Dell logo screen. Anyone know how to fix?
EDIT: Tried again this morning, the phone boots does the flashy dell logo animation a few times then something like a home screen appears with the lock/silent sliders for about 5 seconds then it restarts the whole process... Tried rebooting, removing battery still same problem
