So I recently followed the directions to put Nitdroid on my n900 internal memory, and sadly, I ended up rebooting to a choice of only booting Nitdroid.
Pressing 0 makes it do this:

Maemo (default)

BOOTING - PLEASE WAIT

Kernel: 2.6.28-omap1
Params:
Modules:

Can't flash kernel, required files not found
Guru Meditation #00000025.62017712

Press any key to Panic!

Then obviously, I do press any key, and bam. back to the multiboot screen.

What do I do, other than a full reflash?

Thanks in advance
