My understanding is that the method utilized to activate a non-Verizon handset (*228 3) and/or the online tool, no longer work with non-Verizon handsets. This said, when updating the ROM on your existing Sprint handset would likely yield undesirable results--as the authentication keys and other configuration information would be overwritten with the new ROM. The way to solve this in the past was to merely "re-activate" the handset using *228 and/or the online tool. You run a risk of eliminating the ability to use standard services.

With that option gone, the task of getting any replacement ROM to work on Verizon's network is either impossible, or arduous. (Even more arduous than it was in the past.)
