All my NAND got lost after update!

[Someone7272]

It's not really 'lost' it's just not being recognised no more.
I recently updated from r7719 to 3.0.153 and my Wii main menu is now BLANK. All I have is a disc channel. All my save games from the previous version are gone, and the only game on the save game blocks is Just Dance 3. I still have the actual save game files in the title folder, but for some reason, none of my NAND is no longer being read. I have a copy of my NAND, however, it does not include the saved games which were made from thereon. My Wii no longer works too. If I open up a game supposedly without a save and open Wii save folder, all the files are there. When I start the game, the save is still intact and gets added to Wii's data management. However, I still don't have a Wii Menu with the usual stuff. So basically the update has blanked everything, and the save game database looks like it needs to be painstakingly rebuilt. I can manage that, but it won't fix the Wii's menu.
What should I do?

you need the file User/Wii/Sys/uid.sys

or better yet the whole User/Wii folder

Do you mean a UID.sys from the Real Wii? I found a backup NAND dump.

[LPFaint99]

from where ever you took the wii/title folder from

uid.sys contains a database of Titleids

when moving a nand from one version of dolphin to another bring the whole wii folder

alternatively, run all of your wii games in dolphin at least once (dolphin adds titles to uid.sys)

Restoring the uid.sys from my old NAND dump fixed it. I didn't realise the new builds were bundled with a default uid.sys and went and foolishly overwritten my old one! Just goes to show why to keep backups. Thank you so much for a fast reply. I'm just getting Dolphin to add the new games to the database. Thanks again!!
