[GUIDE][FIRMWARE] QLink Scepter 8 Factory Firmware Restoration & Upgrading Guide
- Thread starter Viva La Android
- Start date
Bad news. I think we have our first bricked in a hard way tablet.
We have done every method that’s here and any other method, we’ve used every computer we have (Mac, archlinux, raspberry pi os, windows 10, the sd card, and crossed fingers mediums) but to no avail. We made sure the drivers were correct and used the logs to see activity but for not.
All we can get it to do is turn on with a blank but brightly lit screen and nothing more.
We can get it to be recognized in FES mode with the button presses method, but the programs time out like it can’t then transmit to the tablet. Like it’s not able to receive.
So we tested the cables and the connector on the board and sound no fault there.
At one point this thing work. Now it sets bricked and cannot find anything recommended to get it out of it.
So before you go asking, we have read the forums countless times, did EXACTLY as described multiple times and used the correct firmware (v6 then v9 for the trill) with no life being breathed in to the thing.
What ideas you have?

Well, I'm a staunch believer in the concept that Allwinnwer tablets cannot be hard bricked from user-end modifications. So the tablet is being recognized and flashing commences, but the process times out? That is an odd behavior I have not yet heard of.
Have you by any chance tried Method 4 with PhoenixCard? It allows you to flash the firmware image from an SD card.
I'll research your issue via the official Allwinnwer chipset release docs and see what I can find out.
Can you send the a100 cf chipset firmware and patched image to a fellow tenneseean?? Chattanooga here.920.57 MB file on MEGA

Sorry running android 12 a100 chipset and CF. I can't get firmware or patched boot. Also I noticed github has the tree files for twrp? Is it operational? And as for brickjng I agree. I've got my scepter 8 booting up with wrong firmware "Im guessing" but I have no screen. I know ghis bc I can run adb commands.

The firmware for the Gen 1 should be working on the links. I'll post you a patched boot image file shortly.
Magisk patched boot.img a100cf
On the TWRP tree, I was not aware. To the best of my knowledge no kernel source code has been released for either hardware variant of the Scepter 8.
In case link isn't working, a100 CF firmware

Viva thx for your help and support. I'm not sure how but my device says its an a133 through running adb shell get prop. But under the back cover it's an a100.can you plz sen d a133 cf running 12 to try.
I was in the sMe boat but I'm not very easily to give up on much. Here is what I did. Same scenario you have by flashing the wrong software countless times. Then I noticed my computer was picking up the ol scepter government 8 nexus 6 wannabe. Hold power button 10 sec to ensure its definitely off. Have computer booted up and on device manager. And yes I'm still blank screen now. Wink wink Viva my friend. Anywho. Power up you tablet and immediately plug in to your computer. Mine will go edl then it shows scepter as other devices and fortunately next it goes into adb device... blank screen. At this point you have options to work the adb kungu and then fastboot reboot bootloader. I've pulled it out of the same dead screen several times by fastboot flashing. Hope this helps. I'm hoping your device is in the same scenario. I think what's happened is we've flashed different chipset software and and our video drivers are not compatible. But I'm sure we can get out of brick state with correct firmware and patched img. I'm trying to make my own patch image rn with canary magisk and not having much luck. Either way hope this helps sir
I've got a completely different build number. Or am I missing something? Can someone pls tell me which firmware I should Use.
Last edited:
I also have the same build and stuff. The link on the first page, the modified boot file is missing, and also the firmware downloads are missing or else I just make my own
Edit: not missing but mega took it down
Does your serial number begin with CF? If so, you can use any firmware from the Android 12 "CF" heading. I will be repairing all firmware links tonight, as well as links to the root boot images.
For any members needing Scepter 8 firmware images, I will be fixing all links tonight for all builds.
Thx. Flashed the modified boot and it won't start now so thx for re uploading the firm wars files
Firmware builds for all models & variants are now available via the download links in the OP. The remaining dead links will be fixed very shortly .
Can you please just link me the boot.img file thats all I need. It should be less than 50mb not the whole img 2.2gb. If you have that it would be much appreciated then I can use Magisk to patch the boot.img then "adb reboot bootloader", then "fastboot flash boot boot.img", then "fastboot reboot" done. Just cant find that little boot.img file. By the way I'm using debian. Also I've found that the build numbers have to match up otherwise you run into issues and bricking. Also you should be able to post the boot.img here in the forums I see them in other threads for other devices.
Thanks for your time and hard work Viva La Android.
I fixed the link for the Android 12 patched boot image in the rooting thread. The build numbers do not need to match. The boot image on the Scepter 8 is based on the Android Common Kernel (ACK) implementation, which is fully backwards compatible. As long as the boot image is more recent than the boot image currently on your device, you'll have no issues. You can use an image extractor and unpack all the individual partition images from the firmware.

1I just want to point out. When helping another user. When the device have been in bootloader too long the battery won't charge and it stays on but when trying to load the OS the boot fails and the device will if plugged in reboot like a boot loop. Also the PC software that detected the device also caused it to send a reboot command automatically to it once adb is active during boot. So after your PC flashed the software did you unplug it from the PC?1I haven't been here for a decade so few ? First I can't get to first page so I can read what's been happening and if this Scepter tab is going to be useful if I TRY and root it ! As of now this tab has been restored 20 or more times because it doesn't work hardly I first tryed to get my money back for it$10 dollars, but I'll get back to first problem - I can't get to frist page to inform myself of issues a screen keeps dropping down with a post from scarlet letter think that's the name and the page is sent to 9 Why is this I'm trying to read on my iPad now can't seem to navigate this forum, if someone might have idea of what I'm doing wrong . Second question is rooting this tablet does it run with out the problems it seems to have sorry to ask Stupid ? but after trying to read here for awhile couple different times it's getting frustrating a bit. Somewhere I saw where files were down for a while all I can read is broken bits of this forum I'll stop Thanks folks1
You're certainly not the only member who has experienced difficulty navigating on XDA since the platform's migration over to XenForo from vBulletin in late 2020.
It is simpler to navigate if you are using the official XDA app. The first thing you need to do is tap your account icon, which is the third icon to the right in the lower navigation bar. Then select Settings and disable the Thread Preview option. Now, when you open a thread, by default you will be viewing the full version versus the preview version. Next, go to the thread you want to begin on Page 1. At the bottom of each thread page, you will see a navigation toggle that looks like this:
This will reflect the current page of the thread you are currently on. To go back one page, tap the blue Prev box. To go all the way back to Page 1, tap the double arrows to the left of the Prev box.
If you've been gone 10 years, navigating XDA will take some practice for sure. Welcome back.
Insofar as your inquiries on the Scepter 8, this thread would be a good place to begin. Scepter 8 General Info & Discussion1
You can also use the website via chrome if you open it in desktop mode. It's small text but you can zoom in and out. You can also use landscape mode just know the keyboard will cover most of it. On safari I'm not sure how to request desktop mode. And yes the XDA app works much better..1@Viva La Android wouldn't it be possible to flash slot B with the twrp.img. You can update the boot slot to B with this bootloader with fastboot --set-active=b and once you boot slot B it is empty and the device boots back to slot A after a reboot. Just curious. I used to do this with the pixel XL as the Device didn't support it at the time. It also has the A/B boot only both boot slots have the ability to boot. This tablet will only boot slot A when you switch to B even with the correct boot IMG it still fails and switches back to A same as what would happen flashing a A/B ota -
4QLink Scepter 8 Tablet
Gen 1 & Gen 2 Models
Factory Firmware Restoration
And Upgrading Guide
OVERVIEW:INSTALLING ADB & FASTBOOT:
The manufacturer of this tablet, Hot Pepper Mobile, has graciously provided me with some factory firmware images for the Gen 1 and Gen 2 models of the QLink Scepter 8. Accordingly, I wanted to follow up with a comprehensive guide for performing a full firmware restoration and/or upgrading the firmware to a newer build version. This guide can be used to restore a device stuck in a boot loop, a bricked device, or a device which has become unstable due to issues with the Android OS or corresponding firmware. This guide can also be used for members who wish to upgrade the firmware from an earlier build version.
This guide will be outlined to provide four firmware installation methods, all of which will focus on a Windows-based setup: (1) PhoenixUSB Pro; (2) LiveSuit; (3) PhoenixSuit; and (4) PhoenixCard. These four utilities were developed and released by Allwinner Technology Co, LTD. As such, each proprietary tool provides a comprehensive solution for restoring your device to its stock factory state. While any of the four outlined methods will ultimately achieve the same end result, members may find that one particular utility is simpler to use or works better than the others. In short, versatility is the focal point. The first three methods are standard proprietary strategies for flashing vendor-specific firmware images to eMMC NAND storage. These tools flash your tablet from a powered-off state known as FEL mode, a proprietary flashing protocol based on BROM. It should be noted here that some members have experienced device recognition issues while using PhoenixUSB Pro, PhoenixSuit and LiveSuit. For members who are experiencing insurmountable device recognition issues, I e. the flash tool not recognizing your tablet once it is in the powered off FEL flash mode, I have included a new section in the instructions for installing the proper Allwinner FEL mode drivers. This section should remedy any such device recognition problems. Also, the 4th method, PhoenixCard, may provide you with a viable solution to device recognition problems. PhoenixCard enables users to write a full firmware image to a micro SD card which, in turn, is inserted into the tablet's micro SD card slot. The tablet is then booted, at which time the firmware image on external storage is written to NAND/eMMC flash memory, thus fully restoring the tablet to its factory state. The PhoenixCard method is ideal for users with unresolved device recognition issues, or in scenarios where the partition index has incurred major corruption and fails during standard firmware restoration procedures.
HARDWARE VARIANTS:
There are a four (4) different variants of the QLink Scepter 8, categorized under the two (2) primary hardware models Gen 1 & Gen 2. The original Gen 1 model, released in April, 2021, shipped with an Allwinner-A100 chipset, 1 GB RAM, and Android 11 (Go Edition) preinstalled. The latest Gen 2 model, released in mid-July, 2022, ships with an upgraded Allwinner-A133 chipset, 2 GB RAM, and runs on Android 12 (Go Edition). Regardless of which gen model you own, your device serial number will begin either with the two letters MD or the two letters CF. Hence, there are two variants of the original Gen 1 model, and two variants of the latest Gen 2 model. I am referencing these models and variants in order to emphasize that they are not intercompatible in terms of firmware. Determining your variant is very simple: if your tablet has Android 11 (Go Edition), you have the original Gen 1 model. And, if you are running on Android 12 (Go Edition), you have the latest Gen 2 model. Once you determine which model you own, simply check the first two letters of your device S/N to determine the variant. To avoid confusion and potential firmware mismatches, I have categorized the firmware images under their corresponding models in the downloads section. These sections have further been subdivided under the appropriate S/N variants. Ensure that you download the correct package based on your S/N variant. Otherwise, the Allwinner proprietary flash tools used in this guide will not commence with the flashing process.
While this step is not absolutely required in order to perform a firmware restoration of the QLink Scepter 8, it's a good idea to go ahead and get this taken care of for future needs (e.g., unlocking the bootloader and rooting, if you plan on performing those tasks later on). All of the flash tools referenced in this tutorial are capable of restoring a QLink Scepter 8 which is bricked (a tablet which is unable to boot to the Android OS, and/or unable to boot into either recovery or fastboot mode).
If you have previously installed ADB & Fastboot, as well as the relevant USB device drivers on your Windows computer, skip down to the next section. Otherwise,- Download the 15-Second ADB Installer v1.5.6 from the link below. Extract the contents of the archive to a folder on your desktop, or to another convenient directory.
- Open the utility and press the "Y" key when prompted to install the ADB & Fastboot drivers.
- Select "Y" again when prompted to install ADB as system-wide.
- Next, you will be given an option to install USB device drivers. Once again, press the "Y" key. A Device Drivers Installation Wizard window will be launched.
- Click the Next box in the lower right-hand section. If you receive a red warning notification that the drivers are unsigned, choose the option to install anyway. The Google universal USB device drivers will be installed on your computer.
- It' is recommended to reboot your PC or laptop once you see the notification that the drivers were successfully installed. That's it. Your Windows computer should now be configured with the ADB & Fastboot tools as well as the Google universal device drivers.
INSTALLING ALLWINNER USB DRIVERS:
The first three firmware flashing tools outlined in this guide -- PhoenixUSB Pro, LiveSuit and PhoenixSuit -- restore factory firmware by flashing the NAND/eMMC directly, with the device in a powered-off emergency flashing state known as FEL mode. FEL mode is the Allwinner proprietary firmware flashing protocol based on the hardware embedded Boot ROM (BROM) implementation. All three of these tools utilize FEL mode when flashing firmware to your tablet's NAND/eMMC internal storage device. FEL mode is initiated one of two ways: (1) if the tablet is booted into the Android OS while connected to your computer, the tool will recognize your device, via USB Debugging, and once firmware flashing is ready to commence, the tool will boot your tablet into FEL flash mode which, again, is a powered off state; or (2) if your device is bricked, stuck in a boot loop, or is otherwise unable to boot up, FEL mode can be initiated manually by performing a particular hardware key sequence while connecting the powered-off device to your computer. This key sequence is outlined below in the instructions. In either scenario, your tablet will not be recognized by whichever flash tool you are using unless the proper drivers are installed on your Windows PC or laptop.
Typically, on both Windows 10 and 11, generic drivers bundled with the operating system will enable proper recognition of your tablet while in FEL flash mode. However, because some members have encountered issues with the Scepter 8 being recognized by these flash tools (while in FEL mode), I am including this section to ensure proper Allwinner USB driver installation on your Windows computer, before we get started with the flashing procedure.- Download the Allwinner FEL Driver v1.0.0 from the link provided below, and extract the contents of the archived file to your desktop or another convenient directory;
- Right click on either the dpinst_x86.exe file (for 32-bit Windows), or the dpinst_x64.exe file (for 64-bit Windows), and choose to run the application as an administrator;
- Follow the prompts on the driver installation wizard to install and configure the drivers on your computer. Once complete, a notification will indicate that the installation was successful;
- Select Finish and reboot your computer. Your tablet should now be recognized by the respective flash tool while in FEL mode, thus enabling the firmware restoration process to properly commence.
DISCLAIMER:
This guide involves flashing the partitions of your device with stock firmware. As such, there are always risks involved. By proceeding further, you are assuming sole responsibility and liability for the integrity and operability of your tablet. I am not responsible or liable in the event you damage your device or render it otherwise inoperable on the basis of this guide. Follow the instructions carefully and I'm confident things will go smoothly. If there is something you are unclear about, this thread is noob-friendly, so feel free to ask questions in comments.
Furthermore, some of the firmware restoration methods outlined below will result in all user data being wiped on your device. Before proceeding, and if possible, make a backup up any important files and media that you wish to preserve.
I. METHOD 1
PhoenixUSB Pro For Windows
PREREQUISITES:
For prerequisites, you will need a PC or laptop running on Windows 7/8.1/10/11, the latest PhoenixUSBPro v4.0.0 flash tool (I have provided a link below), the OEM-supplied or a quality equivalent micro USB to USB-A data sync cable, and a factory firmware image that corresponds with your tablet variant (links provided below). In this first section, we will be using PhoenixUSBPro v4.0.0 for Windows. This particular tool is ideal for firmware restoration on devices which are either bricked or otherwise unable to boot into the Android OS. Enabling USB Debugging beforehand is not required, as this tool recognizes the device and initiates firmware installation from a powered-off state, via FEL mode.
Also, this guide assumes that you have already installed the correct USB device drivers on your Windows computer.
FIRMWARE RESTORATION/UPGRADE
This will restore your device to its stock factory configuration, removing any system-level mods, root binaries, custom software, etc. These steps can also be followed to upgrade your firmware in the event you are running an older firmware build version.- Download PhoenixUSBPro v4.0.0 from the link below and extract the contents of the archived file to your computer desktop or to another directory which is easily accessible;
- Download the correct stock firmware package for your tablet variant from the link below and extract the firmware image (.img file) to a convenient directory on your computer;
- Power off your Scepter 8 tablet;
- In the directory where you extracted the flash tool, open PhoenixUSBPro.exe. Once it launches, click on the Image box in the upper left of the interface. A file explorer will be launched. Navigate to the directory where you saved the firmware image (.img file). Select the image and then click Open in the lower right section of the window;
- Now, click the Start button located in the upper section of the interface. A large green checkmark will appear in the upper right-hand corner, indicating that the firmware is now ready for installation;
- Connect the USB data sync cable to your computer, but not yet to your tablet. Ensuring it is powered off, hold the Volume Down key on your tablet and connect the data sync cable to the micro USB port. While continuing to hold Volume Down, tap the Power key continuously until PhoenixUSB Pro recognizes your device, then release Volume Down. You will know your device has been recognized by an on-screen prompt indicating that the firmware installation is initiating;
- The flashing process typically takes about four minutes. A progress bar on the PhoenixUSB Pro interface will show the percentage of completion in real time. When complete, you will see a green checkmark and a notification that the installation has finished;
- Now, close the PhoenixUSBPro flash tool and disconnect your tablet from your computer. That's it. Upon reboot, your tablet will be reverted to its stock factory state and running on an unmodified stock firmware build.

$$ DONATIONS $$
I do not explicitly request or expect donations from members for my work. I adhere firmly to the open source and free use spirit of the Android OS. With that said, for any members who want to donate something, it would be a huge help. Firmware images for both the Gen 1 & Gen 2 Scepter 8 tablet models were previously unreleased to the public. It took several weeks of discussions with Hot Pepper Mobile Tech Support and its CEO, Mr. Shawn Sun, to obtain official firmware images for this tablet.
This is my CashApp link where you can give as little as $1. For those unable to help financially, I understand. A tap on the thanks button, however, doesn't cost a thing.
