Guide to Manually Install Android 5.0 Lollipop OTA Update on AT&T LG G2 (D800)
A few days back, AT&T started the rollout of much awaited Android 5.0 Lollipop software update for LG G2 (D800). The update is available to download via Firmware Over The Air (FOTA) and requires Wi-Fi to update. The update installs v5.0.2 of Lollipop and updates LG G2 from software version D80020y to D80030f. Luckily, it removes some of the bloatware which includes: Browser Bar, Famigo, AT&T Code Scanner and Beats Music. There are still lot of pre-installed apps that you can choose to disable. What’s great is that, this major update doesn’t impacts your phone settings or data but AT&T recommends users to backup their contacts and files.
Users on AT&T network can simply check for the update from: All Settings > General > About phone > Software update > Update Now. But as the updates is pushed in batches, it may take sometime to appear on your device. In case you’ve purchased a factory unlocked AT&T LG G2 (like me in India), then you won’t get the Lollipop OTA update on your G2 unless you’re using a AT&T SIM card on your phone. That’s really disappointing but don’t worry, we’ve you covered!
Follow the below stated step-by-step procedure to install the official Lollipop OTA update on your LG G2 (D800) from AT&T without the need to wait for FOTA update or their SIM card. I’ve tried it on my AT&T G2 in India and it worked like a charm. The guide may look uneasy but once you follow all steps carefully, you can easily update your phone without any issues. All the apps and data remain intact.
Disclaimer: Try this guide at your own risk! We won’t be responsible if you break it.
NOTE: This guide is meant ONLY for AT&T version of LG G2 with model no. D800. DO NOT try it on any other variant of LG G2 as that may brick your device.

Step 5 – “Enable USB Debugging” from Developer options.

Important: After giving this command, you’ll see a pop-up on phone, ADB shell asking for root access. Grant it SU permission.

Wait patiently while the phone updates to Lollipop and optimizes the apps. You can verify the update installation by going to About phone > Software info. Enjoy Lollipop on your G2.
