Hey Everyone, GREAT INFO here ... I cannot stop reading
Here is what I did with my 3.4U system ...
Few days ago ....
1.)Twighlight Hack
2.) Install "IOS16-64-v257-prod.wad" using the "Wad Manager" & restart the Wii
3.) "cIOS36 rev8" install (using ios36-64-v1042.wad on the root of my SD) & restart the Wii
4.) cMIOS_fix.wad from Wad Manager
5.) Start the "Wad Manager IOS16"
6.) Install "Wii Backup Launcher 03g Wiiish v2 EN.wad" (no restart)
7.) Install "DVD Dump v1.2.wad" and restart the Wii ...
8.) Install "cMIOS_rev3" and restart the Wii
I have a 2GB SD Card with everything from the homebrew channel I installed (50+ apps)
30 minutes ago I ran:
"Firmware-Updater_4.0.dol" from within Homebrew Channel, WAD Manager 1.3
It ran perfectly, without a hitch, all installs were 100% successful
rebooted the Wii
Now,
Other than a SD "channel" (or icon) down below, All burnt games still work from the backup channel launcher, DVD Dump works fine and EVERYTHING i installed form the homebrew Channel still works 100%
I also started the cIOS Downgrader, and it launched just fine (however 3.4U is NOT one of the options)
I'm no wizard with this stuff, and my wording above may be slightly off ... but my system now shows 4.0U and it works just like before I installed the 4.0 update.
Happy Camper here
