Roll back to 8107 or previous, from 8773

[godoy.rafa]

Friends, is it possible to go back from 8773 to 8107 or previous, without having a backup? Perhaps flashing original ROM? If so, where to find it?
I'm from Brazil and have an unbranded Omnia W (SHG-i677)...
I've opened two threads at XDA:

8773 - Not receiving facebook messages with message hub - xda-developers

[Q] Two backups with Cab Sender - restore first one - xda-developers

Thanks!!

Damn... I went back to 7740 and upgraded until 8107... Can you confirm that it works before 8107?

Here's a tutorial of how to go back (if you don't speak portuguese, just translate it to english):

Is this for the AT&T Stock ROM? If so, I've been looking everywhere for this...

It the Omina W, still have not seen the Focus Flash or Omina W Firmware posted on XDA yet. So you have to Zune Trick to get update's for Firmware.

I do not use FaceBook so can't help with that..

I wlll have to plug in my headphones and see if I get the popping sound when plugging or unplugging them.

The new ROM won't help you - the Facebook chat is broken in WP.
