Having some serious issues with this now. I rooted via this method flawlessly 6 weeks ago but I bought my wife an Evo last night and now it won't work.
The issue I am having is that when I get to the step with the bootloader, when it checks for PC36IMG.zip, I get the dreaded update fail message. I have tried using SimpleRoot, gbhils walkthrough, and even the idiotproof version at xda and nothing was worked. I've cleared the sd card, downloaded the zip and placed it directly, pushed it via adb with SimpleRoot and I get caught on the same step.
After reading 30+ pages there and this thread I can't find any kind of fix. If anyone has found a resolution to this, hook a brotha up. Thanks in advance for any help.
