I tried this method as well at least 5 times when I lost cwm after installing v6blackdogfix.Is chargemon script picking proper busybox? Look at chargemon log, you should see something like this:
If so, try another keystroke combination to enter CWM (see OP), even if it is not specific to your model (sometimes it works, even when CWM is working properly).Code:19700423 215039: ### chargemon start... 19700423 215039: ### BUSYBOX=[B]/system/btmgr/bin/busybox[/B]
If still not working, your best choice is try a fresh install: rom, root, cwm and finally supercharger.
I think it is the chargemon. Would it hurt if I manually push the chargemon from the install batch to the system?
