Building and installing
There are multiple installation methods for your Asus Asus Zenfone Max Plus (M1). They all rely on flashing one or more partitions on your device.
All installation methods can lead to data loss.
Flashing a partition will erase everything on the partition. Additionally,
the common backups methods, e.g. TWRP, will not backup the
This will produce a folder with a flashing script, and the partition images for your Asus Asus Zenfone Max Plus (M1).
$ nix-build --argstr device asus-x018d -A build.android-fastboot-images
Alternatively, you can build a specific partition image:
$ nix-build --argstr device asus-x018d -A build.android-bootimg $ nix-build --argstr device asus-x018d -A build.rootfs
The device will need to be booted in its bootloader, or
The boot images can be installed using the following command, assuming the
android-fastboot-images output was used.
If you have a system image (
system.img) built, you can use
flash it to the device. Note that it might be too big to fit over the
partition. In such case, it can be flashed on the
$ fastboot flash userdata system.img
Using a flashable zip
An alternative installation method is to use a flashable zip. The flashable zip can be built for your Asus Asus Zenfone Max Plus (M1) using one of the following commands:
$ nix-build --argstr device asus-x018d -A build.android-flashable-bootimg $ nix-build --argstr device asus-x018d -A build.android-flashable-system $ nix-build --argstr device asus-x018d -A build.android-flashable-zip
The first two will flash only a specific partition. The last one contains the partitions of the two previous one.
The zip can either be copied to the device and selected in a compatible
Android recovery, or sent to the device through
$ adb sideload /nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-flashable-asus-x018d-boot.zip
By default it will flash to the
system partition. Some configurations may
change this to flash to the
userdata partition. In that case, no warning is
given before flashing.
This device is also known by the following names:
ZB570TL (Part Number)
E262L (Internal project name)
Fastboot and recovery
They can be accessed by holding Volume Up at the start of boot.
The device can be unlocked using the following Android program that will phone home to Asus.
The link has been saved to archive.org if it is ever needed in the future.
Note that the tool may appear to fail to unlock, and then fail to format the
device. While this is a big security issue for the integrity of the vendor’s
Android operating system, it is only a weird quirk of the device for us. You
can verify that the unlock worked by using
fastboot flash to flash an image
that would be otherwise rejected (e.g. Mobile NixOS or TWRP).
