Download and Install Android 13 on HTC One M8 / M8 Dual (Custom ROM)

Want Android 13 on your HTC One M8 or M8 Dual? HTC never released it, so a custom ROM is the only way. The HTC One M8 (codenames m8 and m8d) launched in March 2014 with Android 4.4.2 KitKat and stopped at Android 6.0 Marshmallow, but the community pushed it all the way to Android 13.

On the M8, the Android 13 build is the unofficial LineageOS 20. It’s the newest Android version this phone can run, marked stable by its developer, and this guide shows how to flash it.

Android 13 on the HTC One M8

Android 13 builds on the Material You design with themed app icons, per-app language settings, a redesigned media player and tighter privacy controls, including a photo picker that shares only the images you choose. The M8 gets all of that through LineageOS 20, which replaces HTC’s old Sense software with a clean, close-to-stock experience.

For a 2014 phone it runs well, though you should expect the occasional bug since it’s an unofficial build. There’s no stock-AOSP Android 13 ROM for the M8 beyond this; other Android 13 ROMs for the phone, where they exist, are based on the same community work.

Before you start

• This works on the HTC One M8 (m8) and M8 Dual (m8d) only.
• Charge the phone to at least 50%.
• Back up your data. Installing wipes the phone.
• Unlock the bootloader and install TWRP recovery first. Use a recent TWRP build, since older ones can fail to flash an Android 13 ROM.
• Install ADB and Fastboot and the HTC USB drivers on your PC.

Download the ROM

How to install Android 13 on the HTC One M8

1. Copy the ROM zip and the GApps zip to the phone’s storage.
2. Boot into TWRP recovery with adb reboot recovery, or use the volume and power keys.
3. In TWRP, tap Wipe, then Advanced Wipe, and tick System, Data, Cache and Dalvik/ART Cache. Swipe to wipe.
4. Tap Install, select the ROM zip and swipe to flash it.
5. Without rebooting, tap Install again and flash the GApps zip.
6. Go to Reboot and select System.

The first boot can take several minutes. If it hangs, boot back into TWRP, repeat the wipe and flash again.
