How To Capture OTA Update on AT&T LG G6

The most basic and easy way to upgrade your AT&T LG G6 is to wait for the airborne software update. It will knock into the device on its own. It’s fairly an automatic process, but sometimes the automatic update gets stuck. You may not get to see the update even after weeks of the rollout of the software. Here you can search for the update on your own and capture it as well.

To do it, go to your device Settings > General > About phone > Update Center. Then tap on System updateCheck for update. If the new software update is available it will show up with the recent changelog and the build number H87121m. Then just tap on Download to initiate the update process. Keep in mind to charge the battery of your device up to 50% to avoid power related issues. After the installation, you will be prompted to restart your device. Doit and the device will boot up with the new patch of February 2019.

To download the software updates use the Wi-Fi network as it will save the carrier data charges. Alternatively, we have put up the firmware which brings the February 2019 security patch update for AT&T LG G6. You can find the download link for the firmware and installation manual below.
