Follow his post step by step, and
my additions in RED. (See below)
1. Download and unzip the files I have attached to this thread and put them somewhere that you can push them with adb. (
here)
I put them in c:\sdk\tools\
2. You must used Unrevoked's latest tool to install clockwork.
(This is after everything has been completed.. ignore this step).
3. Boot into clockwork recovery, go to partitions, and mount data.
4. Type this code:
adb push flash_image /data
adb push mtd0.img /data
adb shell
chmod 777 /data/flash_image
cd /data
flash_image misc mtd0.img
exit
adb reboot oem-78
Watch for your phone to reboot to a silver HTC logo.
Then type:
fastboot devices
Verify your device shows up...
mine said H************** (random numbers and letters)
I skipped the RUU completely... Follow my steps now.
1. Download this file (PB31IMG.zip) from any one of these links: One Two Three
2. Copy PB31IMG.zip to your sd card. **MAKE SURE THE CARD HAS BEEN FORMATED AS FAT32 AND THE DEFAULT ALLOCATION SIZE**
3. Boot into HBoot by removing the battery and putting it back in. Now hold the Volume Down button and the Power button at the same time.
4. The phone will recognize the PB31IMG.zip file and restore everything.
**NOTE** During the restore... my screen turned off and the phone rebooted and started the restore again.. I freaked because I thought it was in a boot loop. Just let it do its thing. Don't remove the battery or anything! Once everything is complete, it will ask you to reboot.
5. Done!!! Have a beer.
6. Now you can continue with the normal Unrevoked 3 Root as normal.
