Default [Q] P765 dead unexpectly

P765 in ICS V10C

It dead unexpectly

First, I try to plug the phone to my PC and it appear and disappear in device manager with the name of OMAP4430. I install the fastboot drive and then it rename as "TI" something in device manager.

Second, I use the fastboot script in the forum and choose the option 2 (and try all the other option). It show "failed remote partition does not exist."

And then I try to use the fastboot script but this time I hold the vol + button when I plug the usb cable. This time the lge mobile usb serial port appear in device manager and I am able to use the KDZ tools to start the phone update.

However, the update was stuck in about 2 mins after the lge mobile usb serial port auto appear. I check the device manager, lge mobile usb serial port will automatically disappear and the update progress was aborted. The best result so far is about 50% and stop.

How can I stop the phone auto disconnect with the PC?

Thankyou~!
