Here's a thought, as crazy as it sounds...
If HTC Home Plugin 2.1 won't work on the leaked rom that you are running and the HTC Home Plugin 2.1 does work on all of the other custom 6.1 roms, then why don't you just flash to one of the custom roms that do work?
Declare Problem as UserError
Declare PissedOff as EmotionalState
Declare FlashRom as ObviousAnswer
If Problem = "Persists" and PissedOff <> "HappyAsHell" Then
FlashRom = "True"
End If
