Had a few issues my own stupid fault left on my 3rd Party Battery Grip during the 1st part of the ML Install (enabling bootflag) I’m just so used to having it on there I forgot all about it. Now my camera only works when the grip is installed. I thought this would be ok though as I removed the Grip before I put in the bootable SDcard, but it wasn't.
Gone through ML de-install, reinstalled the latest canon firmware again over the ML version. The camera only works with battery grip no matter what firmware version I run or memory card/Battery/power supply configuration I use.
If I try and turn on the camera without the grip installed the camera is just dead.
If anyone has seen any links or other forum posts on a way of setting the cameras NVRAM back so I can use a battery or power supply in the camera I would appreciate any help.
Info on my current set up:
550D running Canon/ML firmware 1.0.9-ml-2010D
