G710ULM Update via OTA or Bridge both fail

Posted on 2019-07-09 23:20:38 Unlocked Phones Vote Up0Vote Down
I have a factory unlocked G7 running version update version G (G710ULM10g). When I manually check for software update from the phone, it says I am running the latest even though version J is available on the web site. Seeing how this is a factory unlocked model, would not expect that I'm using Simple Mobile MVNO should have any effect here.

So next I try installing LG Bridge ver 1.2.54 and doing software update there, but it also errors with "Cannot check software update version". I have tried several times over the past week, no change The phone shows as connected in Bridge, and the backup runs fine. Phone shows it is connected to PC in "File Transfer Mode". Running from home so there is no proxy server, all other internet connectivity is fine.

There is a log created at %LOCALAPPDATA%\LG Electronics\LG Bridge\SWUpgrade\PhoneLog
The log contains the following

-> 18:07:58: [DAVID????]SWVerCheck show popup code = 4

Looking for tips on how to get either update method working.
