I have the same problem as shaq. I was running 4.1U and tried to install cIOS53-trucha.wad via Wadmanager 1.5. I haven't used my wii for months, and couldn't remember if this was the right way to update the system so I could play New Super Mario Bros.
I have a D2CKey, and boot2 installed, and backups of my NAND when it was 3.2U and 4.1U.
Unfortunately I cannot boot to the Wii System menu, but can access bootmii restorer v0.6 via the SDCard. I can access HBC 1.03, however my wiimotes (all four of them) will not sync, so I cannot re-load wadmanager to try to uninstall the IOS53-trucha.wad file.
I restored successfully to both 4.1U and 3.2U, but still cannot access my system menu, and cannot get my wiimote to link to HBC. My HBC does connect to the internet and tries to download 1.0.6, but I can't click "ok" as my wiimote won't work.
So far my Wii is bricked, despite being able to load my NAND backups. Any tips?
I'm thinking of buying a classic controller and seeing if I can control HBC, but unsure if uninstalling that updated cIOS53-trucha.wad will repair my system menu. I though the NAND backup would restore any damage that I had done, but not so
