I've followed the instructions about 5 times now (!) and I keep getting the same problem, whether it be OS2006 or OS2007. I'll do a fresh flash to the 770, the copy will go fine, I can boot into the OS, but after about 30-90 seconds, the unit reboots.

I've seen where people have said that the reboot issue happens the first time they try it, and then to re-flash; but I've done that... I've got a Kingston 2GB MMCmobile Dual Voltage 1.8V/3.3V card, and I have it partitioned in half (which is overkill for the OS side, I know), and the only thing I haven't tried is only giving the OS side 512MB for example, and leaving the rest for the MMC.

Does anyone have any input? Maybe a problem with the MMC card?
