This upgrade method is for ANY Diablo early versions, messed up Diablo versions (installed but not installed, e.g. the 30-2 limbo), probably will also work with Chinook too.

You will lose your bootup menu. This will get your bootmenu back, http://www.internettablettalk.com/fo...230#post252230

You will NOT lose your wifi passwords as well as most other settings.

This upgrade method is mainly for people who are "phobia" from previous "SSU" upgrades as well as those want to skip upgrades, e.g. go direct from 23-14 to 43-7 without going thru upgrades in between, 30-2, 36-5

1) NIT Software Update Wizard installed (dl the newest one from http://www.nokiausa.com/A4410958)
2) Menu/Settings/Backup/restore/New Backup, check all of them, mine is about 18 MB
3) delete apps/books/manual/media files/what nots to make 80 MB space on rootfs, check with diskusage; not quite sure this step is necessary...
4) run NIT Software Update Wizard
5) connect nokia to window box and turn on the N800 while holding/pressing the swap key, the lowest key on the 3 key button, with the icon like a house.
6) 5.2008.43-7 showed up as the latest Diablo, follow on screen instructions
7) when reboot, do a simple setup, the 4 screens setup
8) answer yes when prompted with restoring the latest backup
9) with internet connected, answer yes to "dl and install ALL programs?"
10) press OK to every single apps installed!.... "27 apps successfully installed'
11) You survived!

Upgraded from 4.2008.23-14 (with the messed up 30-2 in a limbo) to Diablo-5.22008.43-7 without a single glitch and wifi connected with password all by ITSELF! No mess up with any settings!

SD boot/bootup menu etc will have to wait for the masters

The upgrade tooke less than 1 minute. Whole process to reinstall apps took 22 min, not one single glitch! YMMV.

Edit: Here is a step by step guide to re-gain your bootmenu, http://www.internettablettalk.com/fo...ad.php?t=22771
