I was told to do a *22899. It made my PRL change to 52xxx and signal was alright but then I heard they were only 3G. So the only way i can get back to the 15xxx PRL was to get a New SIM from VZW. It was free and I just wanted to do a Signal Test to report back here.
These 2 screen shots were taken from the same location outside of the VZW Store-
New SIM PRL 15119
Im running the OTA 4.0.4 Radios.
The only way the new SIM will accept is to start fresh.
-If running a Custom ROM, Wipe Data, Wipe Dalvik Cache, Flash Rom, Flash GApps, reboot and sign in-
-if running Stock, Factory data reset.
No More dialing *22899, it wont update the 4G while on a 52xxx PRL-
so, 52xxx didnt work out, and to go back you had to get a new sim card from verizon?
everything was fine running on 52xxx PRL but i wanted to do a Test. and long and behold my GNex liked the new SIM giving me a Signal Boost. Yes to go back to the 15xxx PRL you need a new SIM and wipe your phone-
