-Open Root Explorer and make sure you're mounted as Read/Write.
-Navigate to /system and long press on build.prop, then select the "Open in text editor" option and look for a similar line that specifically includes the xxxxxx:/user. Edit that line to this:
ro.build.fingerprint=verizon_wwe/inc/inc/inc:2.3.4/GRJ22/222219:user/release-keys
This should make the phone think it's up to date. That said though, I doubt there will be any more updates to this phone.
I can confirm this approach works. At the same time correct information will be displayed in Settings/About Phone
