After a lot of attempts, I found a way to force upgrade to Android 6.0 MM on AT&T LG V10 H900.Before you start these steps:•Make sure you have ADB installed on your computer and running. If you don’t, follow this guide to set it up. Or if you don't want the whole Android Studio, try this guide to setup Minimal ADB and Fastboot•Make sure your phone is stock non rooted. If not here is the link to the stock tot file. And here is the link to the instructions for using tot file.1. Download the Android 6.0 MM OTA zip file.2. Unzip the file, and you get a 20N.up file3. Copy 20N.up file to /Internal storage/SoftwareUpdate/ not external SD card (if folder doesn't exist, just create it)4. Activate USB Debugging on phone and plug into computer5. Open CMD window in C:\Users\\AppData\Local\Android\sdk\platform-tools by holding shift and right clicking and selecting open command window here. (Path may be in different location based on your installation of SDK)6. Type the following command in CMD window:Check and see if your device appears listed. If not, check on phone and select to trust computer if prompted. Run command again once you added computer to trusted list.7. Run this command:This should appear: [email protected] :/ $8. Run this command in ADB shell:Phone Screen should show OFTA Easy Upgrade screen for a few seconds and then reboot to software update.This does not give you root, it simply forces the update to marshmallow.Edit: This method has now worked for everyone who tested it. If it doesn't work for you, just ask for help and either myself or one of the other fine members of the community can try and see what we can do to help.
