Samsung Galaxy S6 SM-G920V Android 7 Nougat issues

[DrSysop]

I am using a S6 SM-G920V originally from Verizon unlocked After 7.0 update every time I boot phone it says searching for service & can't receive calls or texts unless I dial any number first. I changed to a new sim card & that not fixed it. I tried a non activated AT&T & Tracfone sim & a non activated Verizon sim & it says the carrier like it should. Once you activate it the problem exists again. Using a non Verizon sim says this is not a Verizon phone which is annoying but can't disable that. GPS not work now unless you have mobile data or Wi-Fi on. When I go into recovery mode to wipe cache it always says installing update & nothing happens then you see the menu. I did a hard reset a few times & not fix these issues. The sound is low have to keep volume all way up but its a bit distorted from the phones speaker. Please help!

How did you update to Nougat -- via an official OTA system update? Try using Verizon's Software Repair Assistant to reinstall the firmware:
