I've seen this before. I seem to remember that it was an issue with
open firmware not liking the USB flash drive. My first suggestion is to
try a different USB flash drive. Or if you have an SD card to try and
put the files on that.

You probably want to use this image anyway since it has the G1G1
activity pack pre-installed.

If you have never upgraded the OS via olpc-update then there is not a
previous copy to go back to. This is also the case after you have
(sucessfully) done a "clean" install via the secure reflash like you are
currently trying do to with 767 (aka 8.2-767) Only the pristine files
exist until you use olpc-update to update the OS.

We have a few options:
1) Is to just try a different USB flash drive. The vast majority of odd
problems like this during reflash are the result of flaky USB drive.
Sadly many manufacturers don't adhere to the USB specification close
enough. Both Windows and Linux have _lots_ of extra stuff in them to
try and make these drives work right. Adding the same level of support
into our firmware is a huge effort for not much gain and requires lots
and lots of testing. We do try and add fixes for problems that we find
when we have a good test case.
Certainly you should try the above first.
1a) Reformat your USB flash drive and try again. (Some of the issues
from 1 are not hardware but subtle issues with the formatting on the USB
1b) If you do have the same problem with multiple drives then its
possible your donwnload has problems. If you used Windows and IE for
the download we've had many reports of the files being corrupted. Using
Firefox or Linux for the download normally fixes this.
We can use the existing build on the laptop to verify that the files on
your USB flash drive are not corrupted. But it will involve a little
bit of command line work. Nothing too complicated though.
2) Try the same via an SD card. Follow the same instructions but copy
the files onto an SD card rather than USB flash drive.
3) Upgrade your firmware then retry. If you don't have another USB or SD
card large enough for the image then we can try to just put a firmware
upgrade onto smaller devices and update your firmware. Since build 650
we have added many USB fixes to the firmware and its much more tolerant
of marginal USB disks. Plus its a bit better at trying to tell you
whats gone wrong.
4) use olpc-update. Can your XO currently get on the internet? If so
then we can try to net upgrade.
5) Get a developer key and we can debug the problem. This will require
1 of the 3 methods of getting data onto the XO to work. Either via
network, USB or SD. Plus a good bit of technical work.
