After I successfully rooted my Galaxy everything works perfect only my GPS needs a lot of time to find the satellite. Only thing that I've done on my phone is that I followed the guide from this link http://androidforums.com/samsung-i7500/12365-galaxo-tweaks-get-more-memory.html I tried to reset all settings and set again a firmware from beginning it works fine and I tried it again with that guide and again problems with GPS. Is one of that files needed for GPS?
