I've tried installing uboot several times now, and I can't figure out what's going wrong.
I bring up the normal japanese service menu (battery unlock, ok, lock, on), update from my 128 mb CF card. The japenese boot menu pops up, the screen fills with "Writing [hex address], then freezes on "Rebooting the system..."
I've tried waiting various amounts of time, and it never leaves the screen. I pull the power and battery, and the Z is bricked. I have to restore the NAND from a backup.
Any insight?
