Thanks guys! I didn't know I was supposed to unlock before flashing (good thing I haven't flashed yet

).
So I don't miss anything else, I just want to make sure, all I have to do in order to flash is:
1. back up any data on the phone
2. unlock the device
3. flash
And I'm good to go? I guess what I'm scared about is if I am half way through flashing and something goes wrong (file corruption, application frozen, power loss) and I'm stuck with a half-flashed device. Is there a way to rescue a device if it's in this predicament?
Cheers, Dave
