I tried to install the cios that came with backup v.3 gamma but it gave a exception (dsi) message and froze up. So I tried rev7 and it did the same thing, so then I used ciosuninstaller 1.1 to get rid of 249. But, i still cannot install rev7 or the other one. Now I'm trying rev13 and neogamma but rev13 goes through just fine and gives the 2011 can't install cios at the end. I ran downgrader back when I first put on hbc. I'm lost.
