Just unrar, make sure you are hard spl-ed, and run the romupdateutility.exe AS AN ADMIN.
It should flash nicely, an you will get the new rom.
Be carefull: I'm just providing a way to flash the rom, I don't know how to help people in distress, and if you didn't apply HARD SPL from cmonex, it won't work.
I take no responsability, and something goes wrong, I'm sorry for you ;). It worked for me.
Known bug from the rom: headset doesn't work (if it works, please report). Sound works though.
EDIT: ok I found how to get sound to headset. Just plug the headset in and reset snapvue side. If the high pitch sound appear, just reset it again.
I guess this is the workaround for now. Hoppefully someone find something better. At least you don't have to reboot vista.
Sound on WM side doesn't work
