if the misc img hasnt been rewritten,then it would get the main version fail. i was thinking of suggesting this,but wanted to make sure we had exhausted all other possibilities before i suggested it,due to not wanting to add more confusion to an allready fustrated sweetb

Failing those two options I would think you should be able to flash the file through fast boot.
an easier way to flash PB31IMG files

i am inclined to agree... if youre formatting the card in the phone via usb cable,it could be a usb cable thing,an sd card thing,or who knows what,but at this point it looks like for one reason or another the prollem is the sd card.

im still not sure why the RUU wouldnt run either,unless htc sync or something is running on the PC and screwing with it.

i think at this time we should try and flash the PB31IMG in fastboot. just to keep things,in-thread,ill put some real quick directions here:

1)put PB31IMG into your android directory(if thats still what mini-adb inc is renamed in your system). you dont need to change the name of PB31IMG or android to make it work.

assuming you leave it named PB31IMG then open your cmd window and enter(only bold type. blue are just additional comments):

cd c:\android change to android directory

md5sums PB31IMG.zip this will output the md5 sum of the file you will flash. make sure it matches 31bb1611a0fa8197d447c0438426717e

adb devices should output your phones serial number

adb reboot bootloader will boot you into the fastboot screen(white with colored letters)

fastboot devices will again output serial number

fastboot erase cache

fastboot oem rebootRUU

fastboot flash zip PB31IMG.zip

you will see a green line on your phone as the file flashes.youll see outut in your cmd window. shortly after starting you will get a "FAILED!(remote: 90 hboot pre-update! please flush image again immediately). dont worry,this is normal.

fastboot flash zip PB31IMG.zip to flash it again. it will finish this time.

after you get a "finished" message:

fastboot reboot-bootloader this will take you back to the white fastboot screen

fastboot reboot your phone should reboot

heres how it should look in your cmd window:
