I have no idea why doing a prl update (*228, option 2) would have anything to do with being able to run the Froyo update, but my daughter in law's Droid X has been stuck on 2.1 since she got it. The Check For Update on the phone has always been grayed out. Today, she did the *228 and after wards was able to download the update. Doesn't make sense to me, but it works.
