Bootloader Unlocking

And Rooting Guide​

DEVICE OVERVIEW:​

The Hyundai HYTab Plus (8WB1) is a budget 8" Android tablet manufactured by Hyundai Technology. This particular model relies on WiFi and does not support 4G-LTE data connectivity. (The HYTab Plus (8LB1) model has integrated 4G-LTE support.) This tablet is powered by the Allwinner-A133 chipset with a quad-core Cortex-A53 CPU which clocks at around 1.52 GHz, paired with 2 GB RAM and 32 GB of internal storage. The 8" HD IPS display has a resolution of 1280 x 800 at a 16:10 aspect ratio. For connectivity, this model supports both the WiFi 6 and Bluetooth 5.0 standards. It ships with Android 11 (Go Edition) with the Linux 5.4.99 ACK kernel. The 3500 mAh Li-Ion battery keeps the device powered for about 12 hours on moderate usage, and up to 24 hours on light usage ​

DISCLAIMER:

The procedures outlined in this guide involve potentially risky system-level modifications which will most likely void your warranty. Although I have thoroughly tested these procedures on my own device, there is nevertheless an inherent risk of bricking your tablet or otherwise rendering it completely inoperable if these instructions are not closely followed. You are encouraged to fully read this guide PRIOR to initiating the instructions. In any event, by proceeding further, you are assuming sole responsibility for the integrity and operability of your device. I am not responsible or in any way liable in the unfortunate event something goes wrong. Follow the instructions carefully and pay attention to detail; things should go smoothly.

This guide will be outlined in two sections as follows: (1) unlocking the bootloader; and (2) rooting the tablet. Next, I'll go over everything you will need for these tasks.

PREREQUISITES:

Although the following procedures can be carried out using Windows, Mac or Linux, this particular guide will focus on a Windows-based setup. For both sections of this guide, you will need a PC or laptop running on Windows 7/8.1/10/11, the OEM-supplied or a quality equivalent USB-A to micro USB data sync cable, and a Hyundai HYTab Plus 8" tablet -- Model HT8WB1RBK03 Only. If you have not already installed the ADB & Fastboot tools on your computer, along with the proper USB device drivers, follow the steps in the next section; otherwise, you may skip down to the INSTRUCTIONS heading.

ADB & FASTBOOT / USB DRIVERS

For unlocking the bootloader and rooting the tablet, we will be using fastboot mode command lines. As such, it is crucial that the correct USB device drivers & ADB/Fastboot tools are correctly installed on your Windows computer. The simplest and most efficient method I've found is an all-in-one utility called the 15-Second ADB Installer, which configures ADB & Fastboot system-wide, and also installs the universal Google USB device drivers. Download the 15-Second ADB Installer from the link below and save the file on your computer. Right click the file and opt to Run as administrator. Select "Y" when prompted to install ADB & Fastboot. Select "Y" again when prompted to install ADB system-wide. THe ADB & Fastboot tools are now installed on your Windows computer. Next, you will be prompted to instal device drivers. Once again, select "Y." A Device Driver Installation WIzard window will now appear. Click on Next. The Google universal USB device drivers will now be installed. NOTE: if you get a notification dialog warming that the drivers are unsigned, choose the option to install anyway. Now click Finish. It is recommended to reboot your computer at this point to ensure proper configuration of the drivers.

INSTRUCTIONS

A. UNLOCKING THE BOOTLOADER:

WARNING: UNLOCKING YOUR BOOTLOADER TRIGGERS A NATIVE ANDROID SECURITY MECHANISM THAT FORCES THE DEVICE INTO A FACTORY DATA RESET, WHICH COMPLETELY WIPES ALL SAVED MEDIA, FILES, PHOTOS, VIDEOS, APP DATA & SETINGS, ETC., FROM INTERNAL STORAGE. BEFORE PROCEEDING FURTHER, MAKE A BACKUP OF ANY SAVED DATA THAT YOU WISH TO KEEP.

This procedure is a mandatory prerequisite to rooting your device. If you have already unlocked your bootloader prior to finding this guide, you can skip down to the rooting section. Otherwise, let us begin: ​

In your Developer Options menu, ensure that both OEM Unlocking and ADB Debugging are enabled. Connect your tablet to your computer using the OEM-supplied or a quality equivalent USB data sync cable;​

On your PC or laptop, open the File Explorer and select This PC. Double-click on your C drive, then double click again on the folder labeled "adb." Now hold the Shift key and right click anywhere inside the folder. Select the option for a Command Prompt or Power Shell window. Execute this command:

adb devices

If properly connected, ADB will return an alphanumeric string synonymous with your device serial number. Once a proper connection is confirmed, execute this command:

adb reboot bootloader

​

Your tablet will boot into fastboot mode, which will be a black, dimly backlit screen with a green Android graphic in the center. Next, execute this command:

fastboot devices

Once again, if properly connected, your device serial number followed by "fastboot" will appear in the command window. If the command window does not display your serial number, proceed to the next step. If you are connected properly, however, skip down to Step 6;​

Right click your Windows Start icon and select Device Manager from the menu. Locate your device in the menu. Most likely, it will appear under the Other Devices heading as USB Developer. Right click on your device and select Update driver. Next, select Browse my computer for drivers, then choose the option titled Let me pick from a list... From the next list, select Android Device. Click on Android Bootloader Interface and click on Next. Select Yes on the next dialog box. The correct driver will now be installed on your computer. Return to the Power Shell or Command Window and again execute

fastboot devices

You should now see your serial number followed by the word "fastboot," indicating that you are properly connected;​

In the command window, execute

fastboot flashing unlock

Follow any on-screen prompts on your tablet display to initiate the unlocking sequence. Once you receive confirmation that unlocking is successful, execute the command

fastboot reboot

A factory data reset will now be initiated after which your tablet will reboot. It will now be necessary to complete the setup process. Once complete, you must again enable Developer Options and enable USB Debugging from the menu. Your tablet is officially bootloader unlocked (OEM unlocked). ​

B. ROOTING THE TABLET:

I have simplified this step exponentially by providing a pre-rooted boot image. Now that the bootloader is unlocked, attaining root access of the Android OS is as simple as flashing the pre-rooted boot image to the /boot partition. This will install Magisk v24.3 systemless root binaries to your device. ​

Download the Magisk patched boot image from the link below and save it inside the adb directory on the root of your C drive;​

Assuming your device is still synced to your computer from the previous section, reboot into fastboot mode once again by executing the command

adb reboot bootloader

​

Once again, to ensure proper syncing, execute

fastboot devices

After verifying proper sync, execute the following commands ​

fastboot flash boot patched_boot.img
fastboot reboot

Upon reboot, your tablet will be rooted via Magisk v24.3. Once the Android OS boots up, go to your app drawer and open the Magisk app stub icon. You will be prompted to update the Magisk app to the full version, after which Magisk will finish setting up the root environment. That's it -- you are now rooted with Magisk v24.3. NOTE: After rebooting into the Android OS, if you do not see the Magisk app or its stub icon in your app drawer, simply install the latest Magisk app from the official GitHub release page I have linked below and install it on your tablet. Open the app and follow any prompts to complete root setup. ​
