Solve is this:
Download odin, siyah kernel for s3 and aroma file manager
Flash siyah kernel with odin (read on google how to do.. is really easy)
And move aroma file manager to your sdcard
Boot into recovery and mount system and emmc partition
Flash aroma file manager and navigate to /system/ than open build.prop with text editor, scroll down to the bottom and remove all the lines followed by *** by android tweaker
Also move to /system/etc/init.d folder and remove all the files inside....
Phone will be back without any data loss
But I have a problem .. EMMC partition function not found in recovery mode and did not find init.d folder.. I did mount system only because other function not found. Do you have any idea how it works with eMMC partition?
PS: Sorry for my english !
@jumbobombo : yea, i'm on official Samsung ROM - I9300XXDLIB , and does not work with the cache partinion
@corrsea: I have important files on the phone .. I can not afford to lose them. That's why looking for another solution than reflash, because that I could do much time.
