Well, first of all, I have to say I backuped eeproms (1F0000 and 5F0000) with UNISIEMENS, but they were no necessary.
First of all, I flashed my phone with flash-s45i-040510.zip, which can be downloaded HERE.
After that, phone buzzed, did not work properly. I desperated. But somewhere I don't remember where, I found a proggy which saved my life. You can download it HERE .
Procedure is very simple: Run S45i Activator, read phone (press READ PATCHES) and check out which phone values are NOT OK (right window). Tick in left boxes those values which are NOT OK and press WRITE PATCHES. You don't need to check boxes of things that are OK.
After a while, phone should be working. If not, unlock phone, and if still does not work, run S45i Activator again and read/write patches again.
Good luck and best regards!
