How to install Stock Marshmallow H90021x firmware on AT&T LG V10
To update AT&T LG V10 on H90021x firmware you don’t need to download multiple file for it, just you need your device and the working internet connection. You must also remember that OTA process works only on Stock devices which means your device is no longer rooted while you searching for latest firmware via OTA. If you think your device is rooted then don’t waste your time switch to alternative firmware update processes or if possible un-root it and then give it a try. But we don’t recommend you to get stuck in such a long un-rooting process just manually if the download link is available. If you think you are all set to go, then
Go to device Settings >> tap on About device >> Software updates.
Now tap it to check the latest available firmware. Upon it’s availability you will be prompted about the update, now what just tap “Download Now” to instantly download the firmware or “Download later” if you wish to download later. Some times it depends on the region too for example, if the update is released for a specific region but you are not present there it will take some delay until firmware update reaches that region
