So did the OP try a new bluetooth module? I have the same problem - my wiimotes won't sync, but I can use a gamecube controller to navigate the HBC. I can even restore my NAND backups from bootmii (installed in boot2), however, I still cannot get to the "health warning" - I am stuck with the black screen of death. I know my backups work - as I've used them before to restore the wii to 3.2U.
I have ordered a bluetooth module and triwing screwdriver, and will report whether I can fix my wii.
