Upgrading your phone has nothing to do with luck -- it has everything to do with following the steps necessary correctly.

In your case you let the SPRINT customizations run even though you are on VERIZON...there's warning signs not to do that all over the place. Even if you just once "started" to let them run it will mess up your phone a lot and take LOTS of small fixes to work correctly.

If you follow the instructions provided, for example in negaman's helpful post, all will be fine and you can have a XV6900 with GPS & REV-A without problems, just like the rest of us ^^
