Charge the phone so it has a good charge.
Turn the phone off hold the camera button and power button down and then push the reset button. This may take several tries till u get the tri colored screen with text on it.
If you cant get it to work that way take the battery out completely and then hold the power button down + camera and insert the battery while holding those buttons down that will 100% all the time put the phone into the bootloader.
Hook up the phone with the usb cable to your pc while in the tri color bootloader mode.
Download the rom from the above link run the exe file. Hook up the phone with the usb cable to your pc while in the tri color bootloader mode.
Don't worry about the nag screens telling you u need to have an active sync connection skip through all those screens till you get to the flashing part.
Click and start the flashing process this will be just like a hard reset but will replace the rom image on the phone first. so if anything was messed up in the rom or from a bad flash this will fix it.
Wait for the file to reboot your phone and follow the steps on the phone screen to finish up.
