downgrade firmware

Tue Oct 4 14:18:14 EDT 2011

Hi all,

We have several laptops with a firmware version that doesn't work and we
want to downgrade to a previous signed firmware. I think that we could make
a fs.zip containing olpc.fth script whith the lines to do the downgrade.

I did a basic script, but when XO boots I get the message

restarting to enable SPI FLASH writing Try again after system restarts

After restart, the laptop shows the same message again.

 Somebody knows how to solve this?

Thanks,
Esteban.
