Install /e/OS on a Asus Zenfone 6 (ZS630KL) - “I01WD”

The instructions in this guide will assist you to install /e/OS on your I01WD. Please read through the instructions at least once before actually following them, so as to avoid any problems later.

It is important that you know that downgrading Smartphones on OS versions greater than the /e/OS OS version you plan to install, can cause instability or at worst brick some devices. We recommend that you check your current OS version, before attempting the installation.

It is advisable to flash your device only if you know what you are doing and are ok taking the associated risk. All /e/OS builds are provided as best effort, without any guarantee. The /e/OS project and its project members deny any and all responsibility about the consequences of using /e/OS software and or /e/OS services.

Requirements

  • If required take a backup of all important data from your phone on an external storage device before proceeding.
  • Do not take a backup on the same device as some of these actions will format the device and delete the backup.
  • Ensure your phone is charged more than 50%
  • Check that adb and fastboot are enabled on your PC. If not you can find the setup instructions here
  • Download all the files and images mentioned in the download section below before starting the installation

  • Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.

  • Enable USB debugging on your device. You can find the instructions here
  • Make sure that your model is listed in the Smartphone Selector. Check the model supported. Where available, information on the model supported should show as a pop-up when you hover the cursor on the Device name. The model number supported should be the exact same.
  • Boot your device with the stock OS at least once and check every functionality.
Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it will not work on /e/OS as well. Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.

Unlocking the bootloader

Tip: The steps given below only need to be run once per device.
Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or an online drive

Please note ASUS bootloader unlock App service are not functional for the past couple of months. Only users with devices which are already unlocked should proceed with the installation as the instructions in the Unlocking section may not work .

    • 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.

  2. Connect the device to your PC via USB.

  3. 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.

  4. Install the .apk by typing: 
    adb install Name_of_unlock_app.apk

  5. Run the application Unlock Device Tool from the device and agree to the terms.

    Follow the steps as given on the ASUS support site to complete the unlock process

  6. Press the button to unlock your device.

  7. 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.

Temporarily Booting a custom recovery using fastboot

  1. Connect your device to your PC via USB.

  2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type: 
     adb reboot bootloader
  3. Once the device is in fastboot mode, verify your PC finds it by typing: 
     fastboot devices
  4. Flash a recovery image onto your device 
     fastboot flash boot recoveryfilename.img

    Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section

  5. Manually reboot into recovery mode
  • With the device powered off
  • hold Volume Up + Power. Keep holding both buttons until the words “Fastboot Mode” appear on the screen, then release. Now with the volume rocker select “Recovery mode”, then press Power.
Tip: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.

Ensuring all firmware partitions are consistent

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

In some cases, the inactive slot can be unpopulated or contain much older firmware than the active slot, leading to various issues including a potential hard-brick. We can ensure none of that will happen by copying the contents of the active slot to the inactive slot.

To do this, sideload the copy-partitions-20220613-signed.zip package by doing the following:

  1. Download the copy-partitions-20220613-signed.zip file from here. It should have a MD5 sum of 79f2f860830f023b7030c29bfbea7737 or a SHA-256 sum of 92f03b54dc029e9ca2d68858c14b649974838d73fdb006f9a07a503f2eddd2cd.

  2. Sideload the copy-partitions-20220613-signed.zip package: * On the device, select Apply Update, then Apply from ADB to begin sideload. * On the host machine, sideload the package using: adb sideload copy-partitions-20220613-signed.zip

  3. Now reboot to recovery by tapping Advanced, then Reboot to recovery.
