Warning: These instructions only work if you follow every section and step precisely.
Do not continue after something fails!

Basic requirements

Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
Boot your device with the stock OS at least once and check every functionality. Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on PixelExperience either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
PixelExperience is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Unlocking the bootloader

Note: The steps below only need to be run once per device.

Download the bootloader unlock app for your device:
- Navigate to ASUS’ support site and go to your device’s page by entering its model number.
- Click Driver & Tools.
- Select Android from the drop-down menu.
- Open the Utilities section.
- Download the Unlock Device App.
- If the downloaded file is packaged in a .zip archive, extract it.
Connect the device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window and change to the location where the Unlock Device App .apk resides.
Install the .apk by typing:
```
adb install Name_of_unlock_app.apk
```
- For example, on the ZE551ML device, it would be adb install UnlockApp_ze551ml_20150723.apk.
Run the application Unlock Device Tool from the device and agree to the terms.

Note: After you agree to the terms, the ASUS unlock app might ask you to login with your Google account. If your password does not work, then you need to enable temporary access for less secure apps here. If you have two-factor authentication enabled on your Google account, you will have to generate an individual app password on the Google accounts settings website, as the unlock app does not natively support two-factor.
Press the button to unlock your device.
The device should automatically reboot into bootloader mode and the message unlock successfully...reboot after 5 seconds should be displayed. The device will then reboot and load Android.

Installing a custom recovery using `fastboot`

Download the custom recovery.

Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
Connect your device to your PC via USB if it isn’t already.
If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
adb reboot bootloader
```
You can also boot into fastboot mode via a key combination:
- With the device powered off, hold Volume Up + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Once the device is in fastboot mode, verify your PC finds it by typing:
```
fastboot devices
```
If you don’t get any output or an error:
- on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
- on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
Flash recovery onto your device (replace <recovery_filename> with the actual filename!):
```
fastboot flash recovery <recovery_filename>.img
```
Now reboot into recovery to verify the installation. Do not reboot into the existing OS, since it will overwrite the recovery you just installed!
- With the device powered off, hold Volume Down + Power. Keep holding both buttons until the “ASUS” logo appears on the screen, then release.
  
  Note: If you can’t power down the device, try long-pressing the key-combination (if any was used in the instructions above) until the device reboots and follow the instructions above

Installing PixelExperience from recovery

Download the PixelExperience installation package that you would like to install or build the package yourself.
If you are not in recovery, reboot into recovery:
- With the device powered off, hold Volume Down + Power. Keep holding both buttons until the “ASUS” logo appears on the screen, then release.
Now tap Wipe.
Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
Sideload the PixelExperience .zip package:
- On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
- On the host machine, sideload the package using: adb sideload filename.zip.
  Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report Total xfer: 0.98x or adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.
Once you have installed everything successfully, run ‘adb reboot’.

Note: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance.

Warning: Depending on which recovery you use, you may be prompted to install additional apps and services. We strongly advise you to opt out of installing these, as they may cause your device to bootloop, as well as attempt to access or corrupt your data.
