debranded firmware can't run on my P1i. Could you help?

Hi everyone, I'm kindly asking for your help...

In brief: I debranded my new P1i and ran firmware update via SEUS. Update was finished without any problem, but after that my phone can't start - when I turn it on, (1) display lights up, (2) Sony Ericsson startup animation appears (and opening melody is playing), then (3) display switches off and these three steps repeat till I'm crying on the floor and even after. If I "rebrand" it and run SEUS again, it records newest branded firmware, which works fine! What's wrong?! How can I get rid of those O2 animations, menus and settings?

More details: I purchased my phone from O2 Czech Rep. I debranded it according to this guide on se-tuning.cz (unfortunately it's in czech, but the pictures are self-explanatory). I managed to get my phone's ids to be something similar to this picture -

Is it allright? I didn't like those fancy square characters and doubled identifications, but I couldn't get anything else. My phone showed two CDAs as well - one ended with /38, second /1.

SEUS offered me updating with GW1 firmware, which was what I needed. You know the rest of the story, it's above.

I made GDFS backup before debranding, so I restored it. Then I ran SEUS, it told me that I already have newest fw but I told it to refw my P1i again. I got newest O2 branded fw into my phone, which works... at least I was glad that my phone isn't dead at all. But I'd like to get rid of O2, it's not my provider.

Any ideas, please? I can provide you with any informations you'd like to know, just tell me. You know, I can't take debranded phone for warranty repair, and branded works fine (I hope! :)). Thanks in advance.

flash with setool

Try it again and then give Feedback, cause normally it would have to work ;)

If it doesent work again, Flash the Phone with XS++ 3.1 and P1i Firmware.

I think you should try again with xs and maybe try an other firmware this time ?
