    LG G4 AT&T h81020n Android Marshmallow 6.0.1 OTA update has started rolling out. Here is a manual update guide for the LG G4 AT&T h81020n Marshmallow OTA update. The build number for the H81020N update is MRA58K. To be able to flash this OTA update you are advised to have the H81010o update version on your LG G4 AT&T. Basically we are going to download the OTA update file manually to the LG G4 AT&T there by simulating the scenario as if you have got the OTA automatically and execute the appropriate apps to install or apply the OTA update on top of your current firmware. As simple as that.

    First you can manually check for the update by going to Settings > About Phone > System updates > Check for update, and see if your device has received the OTA update. If not then you can follow this guide to update the OTA manually. Make sure to have a look on the DISCLAIMER below and understand the risks involved in updating the OTA manually.

    Installing the LG G4 AT&T H81020N OTA update manually may delete all the data on your phone. You may consider taking a backup on your Android before installing this update yourself.
