After the upgraded filesystem has been downloaded via iDS, it is flashed to the iLiad like this:
Code:
gunzip -t /var/update.image.gz && zcat /var/update.image.gz | dd of=/dev/tffsa1 bs=1k
You can the upgrade procedure in /usr/bin/do_updates.sh.
So basically, with some kind of a prepared http link as described here, you might flash your iLiad with any file, right?
