This is not my day. After getting into root and enjoyably testing commands, my 770 stopped functioning. Now it goes into a continuous cycle of partial rebooting, resulting in a message each time stating "Unable To Open," before starting to reboot again. I've taken out the battery to bring it to a halt. I can't reinstall the 2006 OS because the 770 doesn't remain stable enough for the USB connection to be recognized by my PC. Any useful suggestion out there. Thanks.

I cried wolf too soon. I was able to reflash. Now to solve my memory partitioning problems.
