ok i got done it is rooted, any roms available for this?
Sure. There are several GSI builds that you can flash, including a LineageOS 19.1 ROM that runs pretty smooth. Search the Project Treble forums here in XDA for builds and installation instructions. In fact, here's a link https://forum.xda-developers.com/c/project-treble.7259/
Just to be clear, all models of the Scepter 8 are Project Treble supported. Moreover, you cannot hard brick this tablet; restoring the firmware using an Allwinner proprietary flash tool will almost always revive your device back to its factory stock state. So if you botch flashing a GSI ROM, no worries. Restore the firmware and start over fresh.

Bootloader Unlocking
& Rooting Guide

TABLET VARIANTS:
This guide covers unlocking the bootloader and rooting both hardware variants of the QLink Scepter 8 tablet: the 1st Gen Android 11 Go Edition variant; and, the newer, upgraded, 2nd Gen Android 12 Go Edition variant. For purposes of this guide, regardless of which variant you own, the instructions for unlocking the bootloader are the same. Once your bootloader has been unlocked, however, ensure that you choose the correct tablet variant under the section outlining rooting instructions. Due to both hardware and firmware variations, the instructions for rooting each model are mutually exclusive. Choosing the correct variant is very straightforward: if your tablet is running Android 11 Go Edition, you have the 1st Gen model. Likewise, if your tablet is running on Android 12 Go Edition, then you have the newer, 2nd Gen model. To avoid any confusion, the rooting section below has been outlined under two separate headings that correspond with the two tablet variants.
OVERVIEW:
After a rather lengthy back-and-forth colloquy with Hot Pepper Mobile, we have finally been given access to factory firmware images for this tablet. To Hot Pepper Mobile's credit, most of the delay was due to a language translation issue regarding English to Chinese.
This guide will focus on two primary tasks: (1) unlocking the Scepter 8 bootloader; and (2) rooting the Scepter 8 using the latest stable release of Magisk. To alleviate legwork and to cater to inexperienced members, I have provided pre-patched boot images in the rooting section that correspond with the firmware build of your particular tablet variant.


DISCLAIMER:
Unlocking your bootloader and rooting your device are both procedures that carry inherent risks. Because these procedures involve modifying the device from it's stock factory configuration, it is possible to corrupt, damage, or even render your tablet completely inoperable. By proceeding further, you are assuming sole responsibility for the integrity and operability of your device, and thus absolve me of any liability in the event something goes south. I have, however, tested these guides and feel confident that things will go smoothly as long as you follow the instructions carefully. Moreover, I encourage all members to fully read the instructions before starting the steps.

PLEASE PLAY NICE & FOLLOW RULES:
This thread was created with the intent of being a noob-friendly forum. This simply means that new and inexperienced members are fully welcome here, and will be provided with extra guidance and assistance if needed. Please keep in mind that XDA is a global community of developers, enthusiasts and device users. As such, and although English is the only permitted language in the forums & threads, not all members speak English as their first language, and often rely on text translation tools when asking questions & posting. Accordingly, it is very common for words to be misconstrued, meanings to be misinterpreted, and the context as a whole lost in translation. I ask members to be patient, compassionate and respectful to others on this thread. Those members with the knowledge to do so are urged and asked to help newer members, and recall back when you were new here and others helped you.
Please help me with keeping this thread on point by ensuring that all subject matter herein be kept relevant to the topics of rooting and OEM unlocking the QLink Scepter 8. Any posts about other devices or subject matter run afoul of XDA rules and are subject to removal by moderators -- and potential sanctions imposed upon the offending member. Moreover, an on-topic thread keeps things organized and easier to follow. Thank you for your consideration.


PREREQUISITES:
To unlock the bootloader and root the QLink Scepter 8 tablet, you will need a laptop or PC running on Windows 7/8.1/10/11. (A Mac or Linux machine can also be used. For purposes of this guide, however, I am focusing on a Windows setup.) You will also need the OEM-supplied or a quality equivalent micro USB to USB-A data sync cable. Last but not least, you will need to install compatible USB device drivers for ADB & Fastboot on your PC/laptop. I have included the 15-Second ADB Driver Installer below, under the DOWNLOADS section. This Installer will configure ADB & Fastboot system-wide, and installs the universal Google USB device drivers.

•INSTALLING USB DEVICE DRIVERS•
This section is included to install and configure ADB, Fastboot and the proper USB device drivers on your Windows computer. This section can also be used to troubleshoot and fix issues involving your tablet not being recognized by Windows while connected in fastboot mode. If you have already installed the ADB & Fastboot tools (& the proper USB device drivers), and you are not experiencing fastboot recognition issues, you may skip this section and proceed to the bootloader unlocking section.
Many members have reported issues with device recognition while in fastboot mode. I have also noticed a persistence problem with Windows drivers on this tablet. I can manually update the driver using Windows Device Manager, enabling fastboot recognition; yet, once the tablet is disconnected from my PC the updated driver does not always persist, requiring a manual driver update each time fastboot mode is needed. Follow these steps to enable fastboot recognition of your device.
• 1. If you have not yet done so, install the 15-Second ADB Installer from the link below on your Windows PC or laptop. Open the utility and follow the prompts to install the ADB & Fastboot drivers. Next, opt to install ADB system-wide. Lastly, you will be prompted to install the Google USB device drivers. Select Y and install them. You should see an interface informing you that the drivers were successfully installed. NOTE: If you get a warning notification that the drivers are unsigned, select the option to install anyway;
• 2. With your tablet powered off, hold the Power and Volume Down buttons simultaneously until the QLink logo appears, at which time you release the Power button but continue holding Volume Down. When a green Android graphic appears on your display, you are in fastboot mode;
• 3. Connect your tablet to your Windows machine using the OEM-supplied or a quality equivalent micro USB to USB-A data sync cable;
• 4. Open a command window in the path of your ADB/Fastboot directory. Execute this command:
Code:
fastboot devices
If properly connected, the command window will return an alphanumeric string which is synonymous with your tablet serial number. If this occurs, you are finished with this section and may proceed to the instructions for unlocking the bootloader/rooting. If the command window displays Waiting on Any Device, or if your serial number is not displayed, continue with the following steps;
• 5. Keeping your device connected to your Windows PC/laptop, right click your Windows Start icon and select Device Manager. Locate your tablet in the menu. It will likely be located under either the Portable Devices or Android Device heading;
• 6. Right click your device and select Update Driver. Next, select Browse My Computer for Drivers. On the next screen choose the option for Let Me Pick From a List... Now you will see a list of drivers to select from. Depending on the manner in which Windows recognized your tablet in the Device Manager menu, the driver selection menu can vary. If you see an option for Android Device, select that option and then select Android Composite ADB Interface. Or, you may be directly presented with options for Android Bootloader Interface, Android ADB Interface and Android Composite ADB Interface. In any event, choose Android Composite ADB Interface and then click Next. Click Yes in the Update Driver Warning dialogue screen, at which time the drivers will be installed.
• 7. Return to your command window and again execute the fastboot devices command. If your serial number is displayed, your drivers are now properly installed. If you are still experiencing fastboot recognition issues, try using another data sync cable, change USB ports on your computer, and/or reinstall the drivers using the 15-Second ADB Installer.

I. UNLOCKING THE BOOTLOADER:
If you plan on rooting your tablet, this step is mandatory. If your bootloader is already unlocked and you only wish to root your device, skip down to the rooting instructions in the next section below.
WARNING: Unlocking your bootloader forces the device into a factory data reset, which will effectively wipe all saved user data from the device. Make a backup at this point if there are files and media on your tablet that you wish to keep.
INSTRUCTIONS:
1. Enable Developer Options on your tablet by going to device Settings>About tablet and tap Build number approximately seven times. Android will notify you that Developer Options are enabled; this menu will appear under device Settings>System>Advanced.
2. Enable USB Debugging and OEM Unlocking in the Developer Options menu. NOTE: Users have reported the OEM Unlocking option being greyed-out unless you are signed in to your Google account.
3. Now to boot into fastboot mode, and this particular step is extremely important. Android 10 introduced a new fastboot mode for dynamic partitions, known as FASTBOOTD, which is relocated from the bootloader to userspace. This particular fastboot mode supports resizeable partitions within the dynamic scheme, and enables the user to create, resize and delete various logical partitions. However, FASTBOOTD mode cannot be utilized to unlock the bootloader, and will not recognize the unlock command. As such, the user must rely upon legacy fastboot mode in order to unlock the bootloader. From stock recovery mode, you may simply choose the option to reboot to bootloader. DO NOT CHOOSE THE OPTION TO ENTER FASTBOOT, as this option will boot to FASTBOOTD. From the Android OS, you can boot into legacy fastboot mode by executing:
Code:
adb reboot bootloader
Once you see a green Android graphic appear in the center of your display, you are in the correct fastboot mode.
4. Connect your tablet to your PC/laptop using the OEM-supplied or a quality equivalent micro USB to USB-A data sync cable. Next, open a command window in the path of your ADB/Fastboot directory. Check your connection by executing this command:
Code:
fastboot devices
If you are properly connected, the command window will return an alphanumeric string synonymous with your device's serial number. If you do not see this, there is a problem with communications between your tablet and PC/laptop. To troubleshoot the issue, switch to another USB port, try another data sync cable, and/or reinstall the ADB/Fastboot drivers on your PC or laptop. Also, see my instructions above on installing USB device drivers on your Windows computer;
5. Once a proper connection has been verified, execute this command:
Code:
fastboot oem unlock
Once you see the Okay notification in the command window, your bootloader is now unlocked. Execute this command:
Code:
fastboot reboot
Your tablet will now initiate a factory data reset and then reboot into the initial setup for the Android OS.

II. ROOTING THE QLINK SCEPTER 8
Once the bootloader has been unlocked, rooting this tablet is very straightforward. To simplify this guide, I am providing pre-rooted boot image files in the DOWNLOADS section for each tablet variant that correspond with the Android version on which your firmware is based.

INSTRUCTIONS:

A. 1st Gen QLink Scepter 8
[Android 11 Go Edition]


NOTE: If your tablet is running.Android 12 Go Edition, you're in the wrong place. Skip down to the next section.
1. Download the Magisk patched boot image using the link below and save the file on your PC/laptop in the ADB/Fastboot directory. Note that the file is named patched_boot.img. The flashing command below assumes that you leave this file name unchanged;
2. Go to device Settings>About tablet and tap Build number 7 times or until Developer Options are enabled. (This step is necessary if you unlocked your bootloader using the previous section, due to the factory data reset.) Enable USB Debugging in the Developer Options menu;
3. Power your tablet off. Hold the Power and Volume Down keys simultaneously until the QLink logo appears, at which time you release Power but continue holding Volume Down. The green Android will appear on the display to indicate fastboot mode;
4. Connect your tablet to your PC or laptop using a quality data sync cable. Verify your connection using the instructions in Step 4 of the bootloader unlocking section above;;
5. Once a solid connection is verified, execute these commands:​
Code:
fastboot flash boot patched_boot.img
fastboot reboot
NOTE: Your active boot slot should be boot_a. Regardless, the above command flashes your active slot by default, without having to specify slot _a or _b.
Upon reboot, your tablet will be rooted with the latest Magisk systemless root strategy. If you do not see the Magisk app or the placeholder stub in your app drawer, go ahead and download the latest version from the link below and install the APK on your tablet. Open the Magisk app, grant the prompted permissions, and follow any prompts to complete setting up the root environment.

DOWNLOADS:
15-Second Driver Installer v1.5.6
Magisk Patched Boot Image
Official Magisk GitHub Releases

B. 2nd Gen QLink Scepter 8
[Android 12 Go Edition]


NOTE: If your tablet is running.Android 11 Go Edition, you're in the wrong place. Go back to the previous section.

1. Download the Magisk patched boot image and the empty vbmeta.img files using the links below and save the files on your PC/laptop in the ADB/Fastboot directory. Note that the boot image file is named patched_boot.img, and the vbmeta image is named vbmeta.img. The flashing commands below assume that you leave these file names unchanged;
2. Go to device Settings>About tablet and tap Build number 7 times or until Developer Options are enabled. (This step is necessary if you unlocked your bootloader using the previous section, due to the factory data reset.) Enable USB Debugging in the Developer Options menu;
3. Power your tablet off. Hold the Power and Volume Down keys simultaneously until the QLink logo appears, at which time you release Power but continue holding Volume Down. The green Android will appear on the display to indicate fastboot mode;
4. Connect your tablet to your PC or laptop using a quality data sync cable. Verify your connection using the instructions in Step 4 of the bootloader unlocking section above;;
5. Once a solid connection is verified, execute these commands:​
Code:
fastboot flash boot_a patched_boot.img
fastboot flash boot_b patched_boot.img
Now, continuing in fastboot mode, you will need to disable dm-verity/Android Verified Boot (AVB) by flashing an empty vbmeta.img and executing the following command:
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
Next, execute this command to reboot your device:
Code:
fastboot reboot
Note:
Upon reboot, your tablet should now be rooted with the Magisk systemless root strategy. If you do not see the Magisk app or the stub placeholder in your app drawer, go ahead and download the latest version from the link below and install it on your tablet. Open the Magisk app, grant the prompted permissions, and follow any prompts to update Magisk and/or complete setting up the root environment.

The cannot check firmware for corruption notification you are getting means your bootloader is successfully unlocked. That's normal, but the blank screen isn't. On the rear of your tablet, what are the first two letters of your serial number? MD or CF? Also, do you have the Android 11 Go Edition or the Android 12 Go Edition model of the Scepter 8?

Is it just me or are them MEGA links to any type of the firmware files in this or other related threads broken?? I could really use the Android 12 Go version firmware, however not a single link here will provide me with that I seek.

No worries. You can't hard brick an Allwinner tablet. Check your inbox. I sent you a link to the Android 12 firmware as well as the patched boot image you need.

I have an unfortunate update: When I went to turn on my tablet, I've noticed there was a noticeable crack on the top left corner of the screen... and then when I tried to use it... the touchscreen no longer functions. I have no clue where that crack came from, cause that wasn't there yesterday, and I've kept it safe in a drawer until now, so I have no clue how it's possible. Guess the software isn't the only thing that's cheap, cause my 2020 Moto G Power survived way worse without even a single crack.


TL,DR: Touch screen somehow broke overnight, meaning I can't get past the setup screen, so GG no re, this $10 qlink tablet ****ing sucks.
Ha very? ??? I have the same tablet and same issue crack in left corner no touch just finished unlocking bootloader and rooting and the crack crazy part is I have a motog 5g hahahah ..I unlocked the bootloader with a fire tablet and otg cable .. just use a USB mouse with the. Otg cable problem solved ... hope it helps...

You didnt say how to enter fastboot and gave us alot of information that wasn't necessary to just doing what we came here for . i had to google how to get into fastboot VOLUME DOWN AND POWER BUTTON AT THE SAME TIME. not im seeing a green android icon laid on his side with his gut open and keys like a cellphone type style . im stuck there i dont know what else you want us to do from that no where to put in a command.

in other words your instructions on how to unlock the bootloader isnt clear.

"FASTBOOTD, which is relocated from the bootloader to userspace" last reply im giving YOU DID NOT MAKE IT CLEAR HOW TO GET TO FAST BOOT ! I Have CFW on every console i own i used linux im not some NOOB , ive done stuff like this but whateva most ppl will just say F it like i am this tablet not worth it anyway its laggy worse then china tablets im gonna get rid of it fresh out the box anyway it was not a pleasure to "meet" you maybe next time answer right and dont be a (no0b - someone that never gets better at the skill or activity ) at writing tutorials or helping ppl.
I reviewed the OP. The instructions are crystal clear on booting into fastboot mode. No acton needs to be taken. Again, you are the only member who has had difficulties with the instructions.
To quote the instructions verbatim:

"From the Android OS, you can boot into legacy fastboot mode by executing:
Code:
adb reboot bootloader
"


Instructions cannot possibly be any clearer than that

The firmware guide does include links for Linux instructions on restoring factory firmware. Before doing that, simply reflash the correct patched boot image for your model. That should fix things.

    5. Once a proper connection has been verified, execute this command:
    Code:
    fastboot oem unlock
    Once you see the Okay notification in the command window, your bootloader is now unlocked. Execute this command:
    Code:
    fastboot reboot
    Your tablet will now initiate a factory data reset and then reboot into the initial setup for the Android OS.

    II. ROOTING THE QLINK SCEPTER 8
    Once the bootloader has been unlocked, rooting this tablet is very straightforward. To simplify this guide, I am providing pre-rooted boot image files in the DOWNLOADS section for each tablet variant that correspond with the Android version on which your firmware is based.

    INSTRUCTIONS:

    A. 1st Gen QLink Scepter 8
    [Android 11 Go Edition]


    NOTE: If your tablet is running.Android 12 Go Edition, you're in the wrong place. Skip down to the next section.
    1. Download the Magisk patched boot image using the link below and save the file on your PC/laptop in the ADB/Fastboot directory. Note that the file is named patched_boot.img. The flashing command below assumes that you leave this file name unchanged;
    2. Go to device Settings>About tablet and tap Build number 7 times or until Developer Options are enabled. (This step is necessary if you unlocked your bootloader using the previous section, due to the factory data reset.) Enable USB Debugging in the Developer Options menu;
    3. Power your tablet off. Hold the Power and Volume Down keys simultaneously until the QLink logo appears, at which time you release Power but continue holding Volume Down. The green Android will appear on the display to indicate fastboot mode;
    4. Connect your tablet to your PC or laptop using a quality data sync cable. Verify your connection using the instructions in Step 4 of the bootloader unlocking section above;;
    5. Once a solid connection is verified, execute these commands:​
    Code:
    fastboot flash boot patched_boot.img
    fastboot reboot
    NOTE: Your active boot slot should be boot_a. Regardless, the above command flashes your active slot by default, without having to specify slot _a or _b.
    Upon reboot, your tablet will be rooted with the latest Magisk systemless root strategy. If you do not see the Magisk app or the placeholder stub in your app drawer, go ahead and download the latest version from the link below and install the APK on your tablet. Open the Magisk app, grant the prompted permissions, and follow any prompts to complete setting up the root environment.

    NOTE: If your tablet is running.Android 11 Go Edition, you're in the wrong place. Go back to the previous section.

    1. Download the Magisk patched boot image and the empty vbmeta.img files using the links below and save the files on your PC/laptop in the ADB/Fastboot directory. Note that the boot image file is named patched_boot.img, and the vbmeta image is named vbmeta.img. The flashing commands below assume that you leave these file names unchanged;
    2. Go to device Settings>About tablet and tap Build number 7 times or until Developer Options are enabled. (This step is necessary if you unlocked your bootloader using the previous section, due to the factory data reset.) Enable USB Debugging in the Developer Options menu;
    3. Power your tablet off. Hold the Power and Volume Down keys simultaneously until the QLink logo appears, at which time you release Power but continue holding Volume Down. The green Android will appear on the display to indicate fastboot mode;
    4. Connect your tablet to your PC or laptop using a quality data sync cable. Verify your connection using the instructions in Step 4 of the bootloader unlocking section above;;
    5. Once a solid connection is verified, execute these commands:​
    Code:
    fastboot flash boot_a patched_boot.img
    fastboot flash boot_b patched_boot.img
    Now, continuing in fastboot mode, you will need to disable dm-verity/Android Verified Boot (AVB) by flashing an empty vbmeta.img and executing the following command:
    Code:
    fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
    Next, execute this command to reboot your device:
    Code:
    fastboot reboot

    All in good time, man. Just glad someone with knowledge is doing all this. Wish I could help more. My ability to program and compile is equivalent to stick poking. I've done it once with aosp 6 that was awhile ago.
    You seem to know your way around the Android OS pretty well. I'm a developer in training myself. Learning every day. Yeah AOSP 6, I still love working with the Marshmallow builds.
    Ok first things first. I notice a huge performance boost from some kernel level mods. Here is a link to Kernel Toolkit. Install both APKs. https://mega.nz/folder/QYwA0QTA#O_Zg3h_iVkHOdeyU_yOmLw
    First go to the CPU heading and change the scaling governor to Ondemand. Under CPU Governor Params, tap on Performance Profile and select Maximum Performance (you may personally want to scale back to Aggressive or Balanced, depending on your need for battery life). Now, close Kernel Toolkit and restart the app. Next go to the I/O heading. Choose kyber as the I/o scheduler and set the read ahead buffer to 512 KB. Go down to ZRAM and increase to the maximum of 1000 MB. Set Swappiness to 100. Go over to the Profiles heading, create a profile will all settings and give it a name recommended from the list. When complete, tap on the profile, select save settings and then apply settings.
    Now go to the menu button in the upper left of the app. Go down and enable Apply Settings on Boot. Select All and set a 5 second delay.
    Next, download a build.prop editor from Play Store. There are tons of free ones and any will suffice. Make a backup of your system/build.prop before you tweak anything. Open the editor and grant root permission.
    For build.prop edits, locking your launcher into memory helps a lot with responsiveness. Add this line to system/build.prop

    ro.HOME_APP_ADJ=1

    This basically prevents the launcher from being killed by Android's native LMK.
    To increase touch responsiveness, add these lines as well.

    debug.performance.tuning=1
    video.accelerate.hw=1

    Disable the boot animation for faster boot time.

    debug.sf.nobootanimation=1

    Reboot to enable the tweaks.
    Give these a try and let me know your feedback. I'm working on a few more mods to optimize this tablet and I'll keep you posted on those as well.

    Bootloader is unlocked but my battery died after the factory reset, so I’m just waiting for a few more to flash the patched image file. But idk what I did differently, I started from a fresh win10 install and just installed 15 second adb again like before and it all worked this time.
    ROOT Successful

    For some reason, I'm stuck on the part where you have to use the fastboot option. So basically, I got my tablet in fastboot mode (the secondary one with the green android graphic), but when I tried to use the adb function, it doesn't detect my tablet. And also, the command, "fastboot devices" doesn't do anything, and when I try to use "fastboot device" it just says waiting for any device and just... stays there, not detecting my tablet. I tried multiple computers, tried both PowerShell and the command prompt with admin privileges, to no avail. For information, it worked when my tablet was on my tablet is the V9 firmware, but it slightly newer since I just updated to V9_20220224... so maybe that might have something to do with it...
    Sounds like you have a common driver issue. Do this: with your device connected to your PC in fastboot mode, right click your Windows start button and open Device Manager. What is your tablet showing up as? We will need to update your driver. I can walk you through it. Did you install the Google driver from the 15-Second ADB Installer? I am nearly finished writing a guide on properly installing the device drivers. I will link it here when posted. It will give you a detailed step-by,-step outline. I don't think it's an issue with the firmware builds. Fastboot detection issues are common with this tablet due to some type of instability with driver persistence. For example, I often need to update my driver every time I use fastboot mode because, for some odd reason, the updated driver doesn't persist once the tablet is disconnected from the PC and then reconnected.

    i dont have this tablet but another hot pepper device called the poblano. with that i was able to boot into ffbm from the bootloader and have root adb access. then i ran dd on my boot partition and patched it with magisk and flashed it back

    wondering if hot pepper still makes their devices like that or they patched it. either way props to you for getting the fw straight from the oem
