In this blog post we’ll see how we can setup root access and remap remote buttons on Onn. 4k Streaming Box.

We will use following steps to setup Onn. 4k Streaming box. All the scripts mentioned in this post can be found on my Github repo -> Onn. 4k Streaming Box Rooting and Remote Button Remapping

Step 1: Perform initial setup with upgrade and Google signin

Configure the Onn. 4k streaming device normally to setup remote and the initial Google signin.

Step 2: Enable Developer Option and USB debugging

Go to Settings -> Device Preferences -> About -> Build and press Build option 7 times and you should see pop-up message as “You are a developer”. After enabling Developer option go to Settings -> Device Preferences -> Developer Options and enable USB debugging.

This should trigger a pop-up to allow USB debugging when the Onn. 4k streaming box is connected to a Linux system. Select always allow debugging option for the Linux system.

Step 3: Unlock boot loader

To unlock boot loader use Unblock-Bootloader.sh script. When executed Unlock-Bootloader.sh script, the script will perform following actions:

Unlock the bootloader with adb commands

adb reboot bootloader
fastboot devices
fastboot flashing unlock
fastboot reboot

Step 4: Repeat Steps 1 and 2

Now the boot loader is unlocked repeat steps 1 and 2 to setup the Onn. 4k streaming box again. We’ll work on getting root access next.

Step 5: Setting up root

Use the Set-Root.sh script. When script is executed it will perform following actions:

• Download the Onn. 4k Streaming box firmware from https://download.ods.ninja/Android/firmware/dopinder/dopinder-qt.20210519-factory.zip
• Validate md5sum of the firmware with 08fa86ced3da6c50aafe8395fce27fe9
• Extract the firmware to current working directory
• Download latest Magisk APK
• Push boot.img and Magisk.apk to Onn. 4k streaming box via adb push

Step 6: Build custom boot.img with Magisk (Steps to be performed on Onn. 4k streaming box)

To build a custom boot.img file and get root perform following steps on Onn. 4k streaming box:

1. Install a file browser from Play Store
2. Open file browser and navigate to /sdcard/Downloads/
3. Install Magisk.apk
4. Open Magisk app
5. Click on the Install button next to Magisk heading
6. Select the /sdcard/Download/boot.img in Method -> Select and Patch a File menu
7. Click LET'S GO button

Now we have the patched boot.img file stored in /sdcard/Download/magisk_patched_*****.img; we’ll use it in our next step to obtain root access on Onn. 4k streaming box.

Step 7: Getting root access

Use the Get-Root.sh script. When script is executed it will perform following actions:

• Pull the patched boot.img file from Onn. 4k streaming box
• flash the Onn. 4k streaming box with patched image using following commands:

adb pull /sdcard/Download/$(adb shell ls /sdcard/Download/ | grep magisk_patch) ./magisk-boot.img
adb reboot bootloader
fastboot flash boot magisk-boot.img
fastboot reboot

Next the script will print output to let you know if root access is possible or not.

Step 8: Remap the Onn. 4k streaming box remote

Use Remap-Remote-Buttons.sh script to remap the remote buttons. When script is executed it will perform following actions:

• Copies the onntvremap folder in to /sdcard/Download
• Moves the onntvremap folder to /data/adb/modules/ directory as root user
• Reboot the device

Once the device comes back online. No button mapping will be present for the buttons like YouTube, Netflix, Disney+, HBOMAX. Install Button Mapper application from Play Store, grant superuser access to Button Mapper and remap the buttons on the remote as per your liking.

Step 9: Remove bloatware from Onn. 4k streaming box

Onn. 4k streaming box contains following pre-installed apps:

1. YouTube TV
2. Disney Plus
3. HBO MAX
4. YouTube Music
5. HULU
6. Google Play Games
7. Default TV Launcher
8. Netflix (Can not be removed for some reason)

Run Remove-Bloatware.sh script to remove the pre-installed apps you do not need.

Step 10: Install some useful apps

Use Install-Useful-Apk.sh to install the apps you like on your Android Tv. Here are some useful apps for the android TV:

1. SmartTubeNext
