So I pulled my com board, put back in my Pre Minus, doctored it to 1.4.5, then updated the Network Settings and PRL (shows 60680). I then followed the intructions in this post by navinag (Travis updated the post in his quote which makes it a little clearer to the layman:

With that being said, I now show an "Update Network Setting" and "Update PRL" button on my Sprint Frankenpre 2. When I select the "Update Network Settings", the EV marker disappears, and then after a few seconds or more it changes to "Settings Updated" with a green checkmark. On the "Update PRL" when I select it, after 5-10 seconds of "Cancel Update" and the spining circle, it changes to a message that says "No PRL Update Available" with another check mark next to it. Of course remember I did both updates when I doctored the Minus to 1.4.5 and also got the prl.tar.gz file. Before I removed the com board it was showing 60680.
Anyway...I hope you had luck getting yours back up and running.
