Ok, I know nothing. Here's a thought...
http://www.utstar.com/pcd/downloads/...00140_6601.exe is the rom from the 6600. Download/unzip/extract the files from the extrom?
I downloaded it and sure enough, there is a _ms.nbk, but I'm not on my pc with all of the kitchen/tools that I'd need to move forward getting the files out.
I'm not a rom guy, but can we use xda2nbftool to decrypt the nbf into an nba, and then mount it on a pc, or can we just slap it on our 6700?
