Hey guys. I had an old DX laying around. It had the 6.21 update. I used the 1KDS method and flashed the Milestone X system on it. I then went ahead and flashed the Vortex reloaded system on it. It looks like that brought it back to .605. This was my moms phone. She wants to bring it back now all of a sudden. What can I do to make it stock again? I ask because I thought you couldn't once you went on .621 but this went back to .605 when I flashed the rom. Can I flash back to stock? Any help would be appreciated. Here's a couple of things from the about phone section.
Android version 2.3.3
System Version 4.5.605.MB810.Verizon.en.US
Baseband Version BP_C01.09.15P
