I bricked my testing N900 running CSSU thumb by installing U-Boot without creating bootmenu entries. U-Boot came up fine but of course couldn't boot anything.

At that point 0xFFFF gave me that output for the device:
Code:
# ./0xFFFF/src/0xFFFF-i386 -I
0xFFFF v0.6  // Open Free Fiasco Firmware Flasher

Not a local device

I figured I might just have to extract the current CSSU thumb kernel from its debian package [1] and flash it like this:
Code:
# ./0xFFFF/src/0xFFFF-i386 -m zImage-2.6.28.10-cssu3 -f
0xFFFF v0.6  // Open Free Fiasco Firmware Flasher

Apparently It's not that simple since Maemo doesn't boot and of course not even U-Boot does anymore.
0xFFFF now says this:

# ./0xFFFF/src/0xFFFF-i386 -I
0xFFFF v0.6  // Open Free Fiasco Firmware Flasher

Before I do any more stupid things I'd like to ask for advice. There's no data on the device that's worth saving but I'd prefer to only flash what's necessary.
Since I've never flashed an N900 before I neither have any experience with this, nor do I have any images. I obviously have 0xFFFF and I got the maemo-flasher debian package from here [2] (afaik it's the same for N810 and N900, please correct me if I'm wrong).

So can someone please tell me what files I need to obtain and what to do with them (if it differs from the standard procedure)?
The image links in the wiki are dead, so seem the links panjgoori put up here [3].
