Unfortunately it didn't work, it aborted 75% of the way through and my phone refuses to boot or go into recovery mode.
The simple things, rarely are...
Nope, I've read the maderstock file causes boot loops if used over the GB leak. You'll need a full sbf now. If you belong to droidxforums.com there is a thread where you can download a Linux ISO with the full sbf included. Creates a boot CD with a one-click install routine.
Already have RSDLite installed, phone is in recovery mode, it says connected and I am downloading the SBF file.
Unfortunately, so are 4 million other people, so my download speed is no faster than dial-up and it will take hours at this rate...
