Download this rom to your PC:
http://www.shipped-roms.com/download...60660_Ship.exe
Then remove your battery from your device for about 15sec. Then replace the battery and then immediately push and hold volume down button and while holding that button down push and hold the power button until rainbow bootloader shows.
Then toward the bottom it should say serial. Then connect your device to your PC and where it says serial it will change to usb. Then click on the exe rom I told you to download and follow the instructions.
Good Luck!
