Not sure why this works, but it seems to solve all manner of problems.

Personal experience:
 
-
 
-
I recently screwed things up OCing, and went to restore both RootFS and OptFS from images with my tool.
 
-
I restored both "successfully", go to reboot, and get a green message"Malfunction! Device will shut down in 10 seconds".
 
-
I tried to flash my rootFS image via flasher, got an error(I used the -n option instead of -r), and flashed the 1.2 fiasco image.
 
-
 
-
I then booted it, or tried to, and got a "hang on dots" error(probably OptFS error).
 
-
I flashed my RootFS image via flasher, rebooted, and it worked. But, no themes, and blank squares on icons for (optified) applications.
 
-
 
-
I then tried to flash OptFS via my tool - This worked fine.
 
-
 
-
I'm guessing the method I used to restore the RootFS isn't quite good enough when faced with something majorly different. Perhaps it can't access some bit of it?
 
-
In the meantime, use flasher to flash the RootFS.
 
-
 
-
However, I just backed everything up again, then later after some OCing(and getting the same "malfunction" message after a number of crashes), I restored the RootFS via my tool, and everything was fine. So, this may be an isolated problem.

-
Can someone else test please?

BackupMenu for N900/Maemo 5

My current project, BackupMenu is a bootloader-based application that allows you to backup & restore images of your RootFS and OptFS, so you can entirely restore your N900 if you brick it - without starting from scratch.

Currently, to install:

  1. Install "bootmenu-n900" from the "extras-devel" repository
  2. Download BackupMenu.item
  3. Copy the file to the "/etc/bootloader.d/" directory(requires root access)

To run:

  1. Reboot with keyboard slide out.

Current Status

Mainly working, just finding bugs and fixing them. Beta testers needed.

Known Bugs

Potential rootFS restore issue: If, after restoring, the device is "bricked" or doesn't work correctly: 1. Flash the default PR1.2 image to the device 2. Using the flasher utility, flash your backup rootfs image(-r option). Not sure why this works, but it seems to solve all manner of problems.
