Thanks for the image, qwerty12, but it didn't work. My device still won't display any initfs information on boot-up. I wonder if I'm missing a step.

When you guys did your apt-get install, was it clean? The one issue I get is that multiple instances of hildon-desktop get started, which looks weird, and my XTerm only gets half the horizontal screen (except when full-screen). Did that happen to you guys?

To re-cap, here are the steps I took in my last attempt (don't try these, people, they don't work for me):

1. Re-flash my N810 with the latest official firmware.
2. Put the device in R&D mode (--enable-rd).
3. Disable the lifeguard reset (--set-rd-flags=no-lifeguard-reset).
4. Do initial setup (language, table name, etc.)
5. Remove contents of MyDocs (the pre-installed MP3s, videos, etc.), leaving about 160MB free in the root partition.
6. Modify /etc/apt/sources.list.d/whatever-it's-called to replace all instances of "chinook" with "diablo" and to add the username/password for the updates repository.
7. apt-get -d install osso-software-version-rx44-unlocked (download only, at first, just in case)
8. apt-get install osso-software-version-rx44-unlocked
9. (Notice another instance of hildon-desktop starting...)
10. Answer "Y" to a couple of "Take the new version or keep the old version of this config file" prompts.
11. When the install completes, remove the initfs image.
12. flash-and-reboot
13. Wait as my N810 turns off, tries to boot, and fails to boot.

Most recently, after running those steps, I tried to use flasher-3.0 to re-flash the initfs partition with a stripped Diablo version, and that didn't work. I've also tried all of those same steps, except for the flash-and-reboot (thus using the chinook initfs and kernel), with the same effect.

Anything wrong with these steps, guys? Has anyone gotten this working on an N810 yet? Maybe I should try an N800 first....
