Hey I just recently bought a Gh2 battery grip from Ownuser. Every time I attack it to the camera with two, original, FULLY charged batteries I keep getting a message saying "This battery can not be used."
I tried it with the Unified hack and the Vanilla Hack and I am going to try with no hack installed and see what i come up with. A lot of people are having this issue and I am wondering if there is something I am missing that anyone can help with!
