I managed to unbrick my phone. I`ll share it here, maybe I could help somebody out who was in my situation. I tried a few times to flash my s2 in various modes. The only way I did not try was the succesful one. So this is how i did it: Opened ODIN, conected my phone in download mode. Next i put in the PIT file alone, no pda phone or csc, ticked the Re-partition, Auto Reboot, and F. reset time, pushed START, wait untill finished and started again ODIN, phone in dwl modeut in PHONE PDA CSC and no PIT this time, ticked Auto Reboot and F. Reset Time. Start wait till finish. Device starts up.
