Asus Zenfone Max Pro M1: Download/Install Android 11 AOSP ROM

ASUS Zenfone Max Pro M1 (Codename: X00TD) is one of the best in class budget segment all-rounder smartphones by ASUS in 2018. The handset has gained a lot of appreciation and better reviews in terms of its performance to price ratio. Though the device is still running on the Android 10 AOSP developer version instead of the stable build, users are quite impressed with its performance or stability due to the Pure Android UI. Well, as you’re one of the Asus Zenfone Max Pro M1 users, you should know that Asus isn’t active in terms of pushing the latest software updates or even patch updates to its devices periodically. So, if you’re using Asus Zenfone Max Pro M1 and want to download/install Android 11 AOSP ROM then follow this article.

Talking about the Android 11, it’s the latest stable Android OS version right now and only running on the compatible Pixel devices. Whereas some of the non-Pixel Android devices are currently running on the Android 11 Developer Preview version. Although thanks to Android’s open-source nature, Google has already uploaded the Android 11 source code to AOSP (Android Open Source Project). That means now all the custom firmware developers can easily pull out the Android 11 source code and implement their own Custom ROM easily with all the native features.

What is AOSP ROM?

As already mentioned, AOSP stands for Android Open Source Project. A big thanks to XDA Senior Member SagarMakhar for providing the AOSP 11 ROM for the Asus Zenfone Max Pro M1 (Codename: X00TD).

According to the developers or contributors of AOSP ROM, it’s their one and only mission to offer the maximum possible stability and security, along with essential and useful features for the proper functioning of the device.

Asus Zenfone Max Pro M1: Download/Install Android 11 AOSP ROM

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.

Please Note:

  • Flashing ROM and Gapps file at the same time may cause issues. Contacts Sync may not work. So, flash the ROM first and then Gapps.
  • Flashing Mods and Custom zip files may fail.
  • This is neither a GSI build nor a Ported ROM. Don’t try to flash on other devices.
  • Other Gapps package may not work properly. Flash only the mentioned one from the download link below.


  • Enable USB Debugging on your Asus Zenfone Max Pro M1. 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.
