Need kate EFS backup!!

Hey guys, I really screwed up my phone because I did not realize the international version I bought is something different and happily flashed kenzo roms and firmwares.

Now I am smarter, but the damage is done. I urgently need a EFS backup to get my phone signal running again. I've spent hours searching for a link, but there does not seem to be anything there yet.

Could someone with a proper EFS dump (or the tools to create one) please help me out? I would really appreciate your help! :fingers-crossed:
