[Question] Odysseus for iPad3,1

Hello, I'm trying to downgrade my iPad3,1 from 8.4 to 6.1.2 with Odysseus but I've run into some trouble. I basically found a whole bunch of old SHSH blobs that I made with Tiny Umbrella 7 ages ago.

When I use iFaith to check if they are valid (by submitting them to the cydia server), only my 5.1.1 blob and 6.1 blob get accepted. They were all made with TU7 though. I have a 5.1.1, 6.0.1, 6.1 and 6.1.2. I see there is only a bundle for Odysseus for 6.1.2 but when I use that blob and verify it after the xml convertion it gives me a bunch of errors. So are my 6.1.2 and 6.0.1 blobs completely broken? Could they just be in format that I could convert to the correct one? (like how the new tiny umbrella has a format that doesn't want to be uploaded with iFaith) And if it's not possible and those 2 blobs are broken, how are these bundles made? Would it be possible to create a bundle for 6.1? Thanks
