There is a site for the device, I found the ROM for download easilly
XDA won't let me post URL cause I didn't write enogh posts yet ,
Just use google translate to browse through "texet dot ru". If you are having difficulty PM me)
There seem to be two ROM version, the original and a newer, lighter one from 28.08.2012.
I did not try it, use at your own risk.
If you do, please let us know how it went.
If you look in xda forums there is someone here that claims to have already installed those ROMs.
Good luck, Hope this helps
