Quite a bit of info here to sort through, and I've been out of the loop on all this for months now. I rooted waaaay back when 2.2 first came out, and I've only done one update since, so I'm running HBOOT-0.79, and Build Number 3.26.651.6.
I'd like to give this a go, but when my phone reads the PC36IMG.zip file, it scans it, checks it, and then goes back to the bootloader prompts without an option to flash the update. What can I do to proceed with your ROM?
