I am struggling with setting up my new (well new to me) s5. I seem to have it up and running alright, but it is currently on the July 2017 security patch and I have a prompt to update to the August 2017 patch, which I believe is the last one made available for the phone. I have tried installing the update and it goes through no apparent issues. The phone does not notify me that the update has failed, but when I check phone info it still shows the July 2017 security patch and sure enough the prompt to update to the August 2017 patch comes right back up. I have installed the patch some 4 or 5 times. I have also tried the verizon software upgrade assistant. I tried the upgrade assistant once. I started it up and let it go to watch some tv. When I came back a pop-up notified me that connection had been lost and the upgrade assistant stopped responding. Meanwhile my phone had frozen on the download screen. I pulled the phone battery and put it back in, and there seems to be no damage done, but still back to square one. I have no idea what is wrong or what I should try next. Help would be greatly appreciated. I'm a computer guy! Not a phone guy! I have no idea what is going on.
