no need to uninstall HBC/bootmii...
just downlod Modmii, run the wizard...read the .txt guide....just start with step one and reinstall HBC/bootmii (this will assure you get the bootmii files on the card if that's what you were lacking before)...
it does work with 4.3u...and has letterbomb support (don't know what exploit you used before, but it supports all of the 4.3 exploits)....
...if you have further q's, post in the Modmii thread.... best of luck to you!
