LG V20 H910 update to Android 8.0 Any solutions?
I own a LGV20 H910 phone. It has Android 8.0 version, and it works fine on the AT&T network here in Texas, but it has a broken screen. So I bought an exact replacement, knowing it would work because it says so on the AT&T website. However, after inserting my SIM card it didn't work - would not place or receive calls, though texting and email, etc. (on wi-fi) works just fine.
I took the phone to the AT&T Store, and the they couldn't help me. Said they couldn't understand why my original phone still worked!
I discovered that the new phone only has Android 7.0. Attempts to update the Android version from the phone itself does not work. The phone claims it is up-to-date.
When I called Tech support (not local store), he said he could help me. He sent me a text with an att URL that redirected to the Play Store. But I got the message to "Try again," nothing more. In fact it locked the Play Store so I couldn't do anything else. They rep told me my Play Store was corrupted, and I needed to do a factory reset. I said, "No way," since I invested to much time into setting up the phone to my preferences. I said if I could find where the Play Store stored its info on my phone, it would work again. He was too ignorant to help me.
Then he told me to reset the phone to the factory version, claiming it would automatically update to Android 8.0. but I didn't trust him. I seriously doubt that a factory reset will update the phone to Android 8.0, in spite of his assurance. (Words are cheap. If I lose all my work, it won't affect him.)
By the way, an easy way to fix the Play Store problem was to "Disable" the app, then enable it again. That erased the cache. So the tech support guy in India knows no more than I do. He was guessing, throwing non-solutions at me to try to see what might work ...
I need a way to update to Android 8.0 without a factory reset because the phone is still fine for my purposes.
Does anybody have experience with this?
