HTC is one of the smartphone brands that seems quite inactive or obsolete when it comes to multiple model releases every year or even pushing the latest firmware updates to its eligible devices regularly. Most importantly, there is no specific software update support policy which additionally forcing users to rethink their next smartphone upgrade. However, for those who’re using 2013’s HTC One Max handset and still want to get a taste of Android 11 then this guide is for them. Here we’ll be sharing the steps to Download/Install Lineage OS 18 on HTC One Max (Android 11).

No need to mention that the Android operating system is a free open-source platform based on Linux and offers unlimited possibilities of customizations that most of the third-party ROM developers and advanced users always looking for. You can easily flash the custom firmware, flash third-party files, mods, root, custom recovery, and more without any major issues.

Download/Install Lineage OS 18 on HTC One Max (Android 11)

The installation is pretty simple and easy. If you have installed any custom ROM before then you will have no issue flashing the ROM as the process is exactly the same. But before proceeding to the installation let me clear that this build is in the very early stage which means there will be bugs and many functions may not work properly. So, we do recommend not to flash the ROM on your primary device.


  • Enable USB Debugging on your HTC One Max. Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
  • Also, enable the OEM Unlock from the Developer Options.

  • Make sure the bootloader on your device is unlocked and your device is rooted and you have a custom recovery installed.
  • Make sure your device has more than 50% battery.
  • Make sure you have taken a backup of your important data. Now proceed to install Lineage OS 18 ROM (Android 11) on your HTC One Max device.
  • Make sure that you have installed TWRP recovery on your Android device.

Disclaimer is not responsible for any damage happened to your device(s) while following this guide, proceed at your own risk.
