Even I got my LG v10 to enable debug mode, Android Studio still did not detect my LG V10. That is because the usb drive is not installed. I tried LG United USB driver, that doesn't work for V10, That is too new. You need to LG home page and select support page for V10. Lastly, you need to download LG bridge and install it. It bundled the usb driver for V10. Then android studio can detect my V10.

I checked my Asus ZenPhone 6, there are no OTA upgrade for Android 5.0. The one option is to do a manually upgrade.
I checked their firmware download page I searched for the package for (Z002), I cannot find any package for Android 5.0. I downloaded a few packages to try. Finally, I found T00G package is working. I just need to download the package and pasted it into the root folder of internal storage. Then I restarted my phone, it picked up the upgrade package automatically. However, the package required about half hours to install.
After the upgrade is completed, I found the UI got a lot of improvements. That is easier to use and more smooth.

After the power is on, they entered a loading screen of windows, after a minute,it restarted itself. This situation repeated a few times, that is a kind of an infinite Loop of restarting. Finally, it will go to a windows boot manager. Then you can choose to enter safe mode. If you are luck enough, you can go to last restore point. I found this problem are caused by the windows update. In my cases, I had to use the restore image and did a factory reset.
