ok for those that wiped b4 flashing & want to restore data, here is what I've done. Now, I am no Android expert, and to me, this would be the same as not wiping. I know if you get stuck in a boot loop, you have to wipe, so this method may be the answer. I have sent Toast an PM trying to get clarification, w/ no response. I have done this a few times w/ no problems:
1- Make sure you have
HTC Sync installed on your PC
2- Download & extract
Android SDK, I extracted to C:\SDK
3- copy data.img from your nandroid backup to C:\SDK\tools folder
4- open a command window, type cd C:\SDK\tools (or whatever your path is)
5- check to make sure it sees your phone, type adb devices
6- type adb reboot bootloader
7- when the phone reboots, you'll be in Fastboot
8- verify it says
FASTBOOT USB in red
9- on the pc, type fastboot flash userdata data.img
10- you'll see a green bar on the top right progressing
11- when done, on the phone, scroll down to reboot....all done!
