Haaaalp!

I did "apt-get install osso-software-version-rx34" and it installed a bunch of stuff, but it ran out of space unpacking one of the packages (microb-engine?) ... it installed a ton of stuff, but said dpkg had an error. So I tried "apt-get -f install" but it said that it couldn't connect to the repositories... I noticed the wireless was offline. I couldn't reconnect! I guess one of the updates knocked me offline. So I rebooted... I SHOULDN'T HAVE DONE THAT!

Now I can't boot to my flash (endless loop) but my bootmenu is still intact, and I can boot to one of my SD partitions. Is there any way to chroot into flash and continue the update? I actually don't know how to mount the flash partition...

EDIT: Found it!
