Extract FastbootCommanderV1.51.zip on youre PC.
Boot your phone into bootloader.
Connect it to your PC via USB cable. It will show Fasboot USB.
Copy the image file "boot" from the rom you flashed and paste it in the folder "FastbootCommander"
On windows XP you have to extract the rom file to see boot.img. On windows 7 or 8 is more simple.
Double click on "WinRun.bat".
Reboot in recovery.
Wipe cache & dalvik cache.
