Hi,

I proceeded to install the new os (.199) and midway through the os installation the computer died. As a result my phone is now dead. My computer will not even recognize the phone when I plug it into the usb port, so I have no way to install a new os. I am not sure where to go from here. I have tried to run the JL_cmder app, but the computer would not even recognize my phone! When I plug the phone via USB cable to the computer all I get is a series of red blinks on the led display of the phone.

Can someone help me?

Try following these steps:

Be patient, it may take a bunch of attempts before it connects.

Thanks! after multiple tries, i finally got it to wipe my phone.
