Did you fix it yet?
Try flashing in dead USB mode using the original firmware. Take out your battery and hook up your phone with the USB cable and then go to Open Product. Choose your model, then select Flash Software. Click the Software reset button and when the popup dialog box tells you to do so, insert your battery and click OK. Do not turn on your phone. Once the flashing is completed, disconnect the USB and turn the phone on. Now, you should be good to try again. If you want to run an older FW, Google to see if anyone has identified the technique for your model and software yet.
