Best Custom ROMs for LG G6 in 2026 (H870, H872, US997): Android 14 and Older

The LG G6 officially stopped at Android 9 Pie, but custom ROMs can take it much further. The newest builds run Android 14, which keeps the phone usable with current apps and adds features LG never shipped. This page lists the best custom ROMs for the G6 in 2026, the Android version each one runs, and whether it’s still maintained.

Before you choose a ROM

• You need an unlocked bootloader and TWRP. LG closed its bootloader unlock service on December 31, 2021, so this only works if your G6 is already unlocked or you saved your unlock.bin file. See our unlock guide and TWRP guide.
• Match your model. Most ROMs support the H870 (international), H872 (T-Mobile) and US997 (US unlocked). Some also support the H870DS and H873. Always check the thread for your exact model.
• Most G6 ROMs are no longer updated. Official LineageOS support ended with LineageOS 21 (Android 14), and many older ROMs stopped at Android 9 to 11. They still work, but they don’t get new security patches.

The best LG G6 ROMs in detail

LineageOS 21 (Android 14)

LineageOS is the best-known custom ROM and the successor to CyanogenMod. It gives you a clean, close-to-stock Android with useful extras such as a customizable status bar, navigation bar options, privacy controls and a built-in updater. The LG G6 had official builds from LineageOS 14.1 through LineageOS 21 (Android 14). The LineageOS wiki now lists these as previously supported versions, so LineageOS 21 is the last official build the G6 will get. It’s still the best place to start if you want a stable daily driver.

crDroid 10.1 (Android 14)

crDroid is built on LineageOS and adds many more customization options for the status bar, lock screen, quick settings and gestures. If you like LineageOS but want more control over how the phone looks and behaves, crDroid is the one to try. Our crDroid device list covers its newer versions on other phones.

LibreMobileOS and /e/OS (Android 13)

Both focus on privacy. They’re based on LineageOS but cut down on Google services. /e/OS replaces Google apps with its own privacy-focused alternatives and the microG framework. They’re good choices if you want to use your G6 with less Google tracking.

Havoc OS, dotOS and Pixel Experience (Android 10 and 11)

These are feature-rich ROMs from the G6’s most active modding years. Havoc OS and dotOS offer lots of interface customization, while Pixel Experience recreates the look and apps of a Google Pixel. They’re stable, but they run older Android versions and no longer get updates, so newer apps may not support them.

Older ROMs (Android 8 and 9)

AICP, Bootleggers and Resurrection Remix are kept here for reference. They’re very old now, so only use them if you need a specific feature or are testing an older Android version.

Android 12 and 14 GSI guides

You can also run generic system images (GSIs) on the G6. We have step-by-step guides for AOSP Android 14 on LG G6 and AOSP Android 12 on LG G6.

How to install a custom ROM on the LG G6

1. Make sure the bootloader is unlocked and TWRP is installed.
2. Download the ROM for your exact model and, if the ROM doesn’t include Google apps, a GApps package for the same Android version.
3. Boot into TWRP and make a full backup.
4. Go to Wipe and do a factory reset. Many ROMs also ask you to format data the first time, so check the thread.
5. Tap Install, flash the ROM zip, then flash GApps if needed, before rebooting.
6. Reboot. The first boot can take several minutes.

Some ROMs require a specific stock firmware base, such as the latest Oreo or Pie firmware, before you flash them. The thread or wiki page lists any requirement.

What is the best custom ROM for the LG G6?
