I’m shooting in the dark here, but I have a couple more ideas that might help (they shouldn’t hurt at least if they don’t work).
When you restored back to VRAMC3 with Odin, did you wait for ODIN to give a green Pass at the top before unplugging your phone from the computer? (I think it takes at least 10 minutes or so for Odin to do its thing and give the green pass… and the green pass doesn’t happen until several minutes after it reboots your phone). Even if you did, I would probably try reflashing both the VRAMC ROM and the PIT file again in ODIN. (If you are interested in a good Youtube video with step by step instructions how to ODIN restore your phone— I think this is a good one: http://www.youtube.com/watch?v=4qtbEevn1VA
(I would probably stick with the download links though from XDA and just use the video for reference).
The only other thing I can think of is that you might have had a corrupted download of the 4.1.2 ROM or the PIT file… I would check the MD5 checksums for both the VRAMC3 stock ROM and the PIT file before trying again with ODIN.
If you go to Imnut’s thread here: http://forum.xda-developers.com/show....php?t=2040264
, and choose the VRAMC3 “Mirror 2” download link, you will have the MD5 checksum available so you can confirm you have a good download.
Adam Outler provided a link to the PIT file in one of his old threads… and it includes the MD5 check sum— (you can find his PIT download link at this link: http://forum.xda-developers.com/show....php?t=2043636
) …. I double checked the PIT MD5 on Droidstyle’s guide against the one on Adam Outler’s… and the MD5 for both download’s is: 6e874ba443d59ea114e48c1a57f3dfaa …. So, all you really need to do is confirm the MD5 on PIT file from Droidstyle’s guide and if it matches the MD5 above… it is a good download.
(If you don’t have an easy way to check MD5’s, I would recommend this tool: http://www.winmd5.com/
….. It’s really easy to use, just create a file folder and download the zip file to it… then extract the zip into that file and double click on the application to open the program).
I hope some of this helps.
I'd also encourage you to hit the thanks button for the people who provided us all the helpful information-- (Adam Outler, Droidstyle, and Imnuts).
