Default Cab sender


Few days ago I have force update to 7.8 with cab sender and it worked. Yesterday I saw this ROM

and I wanted to put it on my Omnia 7. First I have done back up with cab sender and created restore point in Zune. After that I have downloaded this new costum ROM and my Omnia 7 was unlocked, unbranded and it had a new custom ROM. Next thing I wanna put all my backuped files back to mobile and then problem starts. Zune says it fail to restore and gives no any kind of error, and cab sender says error 801812E canot restore.

Can someone help with this ?
