Did a nand backup. Tried about 10-15 times of ##3828#, with all different combos of not wiping, wiping once, wiping twice. Tried about 5-10 ##786# with the same wiping and not wiping. Installed the stock rooted rom that is suggested. Tried the ##786# and around the 10th time I finally got the Pri 140_003. Reloaded the Nand backup and the Pri stayed 140_003. It seems to be a matter of chance which is great. Location is upstate NY.
PS, I don't see much of a difference in connection speeds and atleast for me it didn't seem worth the effort.
But it does work with patience.
