[maemo-developers] Cold Flash Procedure (fails with lots of

[From: Greg S.]

I've managed to screw up the bootloader on my n810 past the point of *anything*
happening when I attempt to turn it on. (No white screen, no logo, no power
indicator, definitely no USB activity, etc.)

I have a USB TTL (3.3V) Serial adapter and have wired the Rx/Tx and Gnd as
specified in the documentation for the serial port under the battery, but the
cold flash feature of the flasher does not seem to work with that interface.  I
*do* get serial data out of the device when I plug it in and unplug it from the
charger, which occasionally triggers the flasher to do something, but from what
I can tell it's just noise.

Has anyone even gotten this far in attempting to cold flash a device?  I've
found a fair amount of people speculating that it can be done, but no one who's
attempted it.

It's really frustrating to have something that seems to be possible so poorly
documented simply because no one seems to have bothered.

If anyone has any good ideas, I'd love to get this working rather than having
to be at the mercy of Nokia Support every time I manage to break something
low-level.

Thanks,

Greg S.
