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

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.
[Android General] Viva La Android R.I.P.:
@truthbrotha, I provided very clear instructions on entering fastboot mode. Try going back to the instructions and actually reading them. You're the only member I've seen that's had any difficulty in this regard.
[Android General] Viva La Android R.I.P.:
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:

adb reboot bootloader

"

Instructions cannot possibly be any clearer than that
[Android General] Viva La Android R.I.P.:
@truthbrotha if you need help on a specific issue, somebody will assist you. However, do not blame my iteration of instructions for your failure to read and comprehend them. And if you are trolling, please find another platform to troll.

ok so i basically just turned tablet on by pressing power plus vol dwn and green guy pops up i ran the patched img and rebooted now gets blank screen im using linux and the firm ware guide is for windows
[Android General] Viva La Android R.I.P.:
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.
[Android General] sp0129x:
@Viva La Android

Great guide!
[Android General] Viva La Android R.I.P.:
Thanks for the kind words. I wish I got those more often. 😊
[Android General] sp0129x:
Deservedly so. PM in regards to inquiry.
[Android General] lyttle123:
have 2gen Android 12 coul;d i get link magisk patched boot Image please? thank you!
[Android General] Viva La Android R.I.P.:
Yeah I'll take a look and try to locate it. @lyttle123 the boot image you need is live. The link is repaired.
[Android General] harrislee340:
Any one click root methods work with this one? I can't seem to get command line to work with it at all. bootloader is unlocked. I have a patched magisk boot.img. But fastboot devices command, in PowerShell won't recognize its connected. I can use reboot devices and it will reboot. So, I know I don't have a cable connection issue. BUT, fastboot reboot and rebooting into recovery mode don't work from command line. The only way i can get to fastboot is manually (which btw takes me 20 tries) I got an app on my pc called ADB AppControl which has a command line function. IT will recognize the device is in fastboot mode, but when I try to flash the boot image with it. It says the image can't be found. Also, fastboot\recovery reboot command will not work with it either. I don't really have much experience with using a command line. So maybe I made a mistake somewhere setting up Powershells fastboot path? If there's no one click option, could someone maybe help me figure out what I'm doing wrong? Thanks guys! hope Ya'll have a nice Christmas.

Update: Ok so after going through and reading some of the more recent comments. I'm guessing the 15 sec drivers app didn't install the drivers properly. I'll see if that's maybe my issue.
[Android General] Viva La Android R.I.P.:
Let me know how it goes.
[Android General] moorenado6:
The MEGA link isn't working for the Empty vbmeta.img . Please relink. Thank you!
[Android General] Viva La Android R.I.P.:
Thanks for bringing it to my attention. The link is repaired.
[Android General] Viva La Android R.I.P.:
@harrislee340, did you have any luck rooting your device?

And to answer your previous question in full, there are no one-click rooting methods for Android -- period, unless you are running on Android 5.1.1 or earlier versions. As it stands currently, there is only one actively maintained rooting strategy for Android: the Magisk systemless root method, which is the basis of this tutorial.

If the 15-Second ADB Installer isn't installing properly on your computer, let me know; I have an alternative you can use.​
[Android General] moorenado6:
Not sure why but it's not working still.
[Android General] Viva La Android R.I.P.:
I just checked it twice to make sure. The link is working.
[Android General] moorenado6:
Yes it sure is...not sure what the issue was but regardless, root has been achieved. Thank you very much.
[Android General] Joy28:
Hi I am stuck here : Download the Magisk patched boot image using the link below and save the file on your PC/laptop in the ADB/Fastboot directory

How do I save there i am not allowed to use flashes nor do I know what and where this directory is...

When I go to type in command it says it cannot find img i didn't change the name its saved to my downloads in desktop automatically ...??

Thank you so much!
[Android General] Viva La Android R.I.P.:
Guys, and gals, all download links in the OP are working again.
[Android General] Viva La Android R.I.P.:
UPDATE: February 9, 2023

I just received the latest firmware builds for both the Gen 1 and Gen 2 models of the Scepter 8. Accordingly, I will be updating the patched boot images in the downloads section when free time permits. Because the upstream Android kernel is backwards compatible with previous versions, the updated boot images will be compatible with any firmware build corresponding to their respective Android release version. In other words, just ensure that you download the patched boot image that matches your Android version: Android 11 (Go Edition) for Gen 1 models; and Android 12 (Go Edition) for Gen 2 models.
[Android General] Viva La Android R.I.P.:
The rooting instructions and download links have been updated with patched boot images corresponding to the latest firmware builds. In addition, to alleviate the possibility of bugs, instabilities and compatibility issues, I have categorized these patched boot images in the form of the CF & MD variants of the Gen 1 model, as well as the CF & MD variants of the Gen 2 model, equating to one boot image for each of the four possible models & variants. To prevent confusion in this regard, I will revise the wording of he guide later today in a manner that simplifies which boot image members need to download based on the model & variant being rooted.

Well I have wasted an afternoon trying to get your drivers to work but it looks like a lost cause as I read it seems a lot of people are having same issue . I did as stated cable computer drivers so I had couple friends stop by that do IT they weren’t able to get it to work either and it started with the program 15 second ADB had issues we moved it around to diff computer process of elimination cable drivers program somewhere all the files I got here didn’t want to work for us, but what bothers me is people say they got it but Never say a word about How they got it which I know if I got it to work I’d be laying out how and what order I did it in, but hay you never know maybe someday someone will let the rest of us know how to make all this work, Luck be with you but I’m going to put my toys away for later date …
[Android General] Viva La Android R.I.P.:
A couple of weeks ago, for the sake of clarity, I done 6 fresh installations of Windows 10 & 11 on 3 different laptops and PCs, installing the drivers from scratch each time. My Scepter 8 was recognized in all six instances with no issues. So there are no issues with the drivers. Your issue is most likely due to a driver conflicts or user error installing and setting up the drivers. The 15 second ADB installer has no issues. I did take the time to test it again to make sure the installer wasn't corrupt.

Honestly, I'd be quite embarrassed to call myself an IT tech and not be able to get a tablet recognized on a PC. They should probably go back to school for a while.

The people on here stating that they got their devices rooted done so by following the instructions, which I have outlined so even a child can follow them. If you're having trouble with things, just ask for sone help. Either myself or another able member will help you. But don't blame the drivers or the guide. This guide has been successfully carried out on hundreds of Scepter 8 tablets. It's tried and true.
[Android General] vtails:
WOW
[Android General] Viva La Android R.I.P.:
@vtails in the instructions there is a section titled "INSTALLING USB DEVICE DRIVERS." Start with Step 5 and work to the last step to troubleshoot and manually update your drivers. That should resolve your issue.
[Android General] Viva La Android R.I.P.:
The

The command to disable dm-verity is indeed correct. I did double check it just to make sure. Magisk is flashed to the device, by way of the patched boot image you flash via the instructions.

If you follow the instructions to the letter you will unlock your bootloader and achieve root. By the way, you quoted my instructions completely wrong. So if you executed the command per the syntax you quoted, it is definitely incorrect.

This tutorial has worked on dozens of tablets, so my instructions are not all of the sudden incorrect. Your adherence to the instructions, or lack thereof, on the other hand, is the root of your problem (pun intended). Simply follow the instructions in the guide (as I outlined them, and not in the manner you quoted them), and you will achieve bootloader unlocking and root.
[Android General] Viva La Android R.I.P.:
Yeah there is more than one way to disable verity. One way is when using an empty vbmeta.img and the other is with using a stock vbmeta.img. So you'll see different commands to disable verity via fastboot. For this guide and vbmeta.img, the command listed is correct. You can actually copy the command and paste it to your command window to make things easier.

Okay once you flash the patched boot image, if the Magisk app doesn't show up when you reboot, download the app from the link provided and install it on your tablet. Then open the app and follow any prompts. (The Magisk root framework is already installed by way of the patched boot image you installed). On a final note, ensure you are flashing the correct patched boot image for your model and variant. It sounds as though you are close to successfully rooting your device. I will try to get you through the process.
[Android General] Viva La Android R.I.P.:
@GoBobAKnob, did you get your tablet rooted yet?
[Android General] Viva La Android R.I.P.:
No. You cannot hard brick an Allwinner tablet. You would likely soft brick the tablet, resulting in a boot loop. But a soft brick can always be repaired by flashing a factory firmware image.
[Android General] Viva La Android R.I.P.:
If Magisk isn't installed you cannot be rooted. Magisk is the root solution, so without it there can be no root access. There is no need to change any flash commands from my instructions. They are 100% correct and have been tried on dozens of tablets. But, unless you have unlocked your bootloader using fastboot, and without Magisk being installed, I am perplexed as to your statement that your device is rooted. Please feel free to post screenshots as proof of your claims.
[Android General] htc-8925:
would you be interested in a logcat so we can determine if I'm an idiot or if I found the one of these china tablets that is resisting freedom even though I followed your directions as absolutely perfectly as I humanly could?
[Android General] Viva La Android R.I.P.:
I'm not understanding. A logcat for what? Please explain what it is you done and what you're having trouble with. Be detailed with every step you have taken and where you ran into trouble. Moreover, if possible, post a photo of the manufacturer's label on the rear of your tablet. I will cross reference your model and variant to validate that the boot image you flashed is the correct one. Your issue is likewise something very simple. I'll try to help you through the dilemma.
[Android General] htc-8925:
I'm trying again right now, been busy all day chasing fillys across hell and gone since assbags don't know how to not drive through 2 4' barb wire fences... will update shortly. I have a Scepter8 SER# CF2210AP15095396 running BigdroidOS 2.0.0.131 (Android 12 GO build#v03-20220809) and set it up last time with Owner enabled via AllianceSHIELD X so I'm setting up naked and unlocked this time to see if that was the problem with some access denied script entries in the LogCat (crash dump logs)

THREE attempts have now been made at full speed from dead cold stock boot to nothing but a blank, black screen, I updated firmware to the v1 version, on your fimware recovery page and followed every. single. step. verbatim and i get the same result every time///\\\

GOT IT
[Android General] Viva La Android R.I.P.:
Out of curiosity, what was the dilemma exactly?
[Android General] htc-8925:
dud brain betray thinking human sleepy and tried to use files from ****ty spreadtrum tablet was sitting me next to... **** I NEED MORE SLEEP AND LESS COFEVE

Speaking of Spreadtrum/UNISOC, is there any chance you'd be able to get your hands on a Maze Speed t8 tablet and tackle getting the bootloader unlocked on one of those bass turds? I've tried just about everything and can't even put a chink (pun intended) in the armor their "custom ROM" has built around that poor little bootloader.

also, this tablet in particular calls itself a "phone" lol
[Android General] Viva La Android R.I.P.:
Unisoc/Spreadtrum bootloaders often involve the use of proprietary software to unlock. Here is an XDA thread that discusses the procedure and the use of an identifier token to initiate the unlock. It includes links and references to the utilities you will need. https://xdaforums.com/t/how-unlock-unisoc-bootloader.4392557/
[Android General] jsauser11:
I can't seem to get the driver loaded for connecting thru ADB to the tablet. I have installed the 15 sec. ADB as directed, placed the tablet into fast boot mode, connected to the pc, and exicuted the ADB command "fastboot devices", but never get a return. The tablet shows up in Device Manager under "Other Devices" as "ADB Developer", and when I try and assign a driver file manually, it never locates one. Attempting to select from the list I do not see Android Device, Android Bootloader Interface, Android ADB Interface or Android Composite ADB Interface. Where can I find the correct driver? The Hardware ID's for "ADB Developer" that are visable in Device Manager are: USB\VID-1F3A&PID_1010&REV_0200 and USB\VID-1F3A&PID_1010.
[Android General] jsauser11:
I was able to solve it myself. Had to edit the android_winusb,ini file, add in the hardware ID lines in the OP, then, boot Windows into the mode which disables driver signing. Then, the ABD Developer device could be linked to the Google android_winusb.ini file and the Android Composite ADB interface linked to the device in Device Manager. When tested, ADB devices command returned the serial number of the Qlink tablet.

Hello everyone, my girlfriend just got one of these tablets, and we were both shocked at how laggy and unresponsive this tablet is as stock, so I tried to research how to root this device in hopes of increasing the responsiveness and such, and was excited to find that there is an XDA guide and an amazing developer who is helping us get the most out of this thing, unfortunately all the file links seem to be dead/out of commission, is there anyone here who maybe has an alternative to the links or backups of the required files if possible? I would love to try this tutorial out on this tablet. Thanks for any help :)
[Android General] Mad-Mac:

Patched boot/vbmeta links are broken. I gave up, went the long way and magisk'd the boot i got from the stock.

Just stuck on needing a vbmeta.

Nevermind that.

used 'fastboot reboot fastboot', then flashed using '--disable-verification --disable-verity'.
[Android General] wyndyll2:
Can you share the patched boot file? Magisk wont patch mine, always says unsupported format.Weird because I've flashed the v4 firmware, idk it's the v4 thats broken and maybe i should try v2.v6. or v9. I have unlocked the bootloader and flashed a patched version I found online (Non viva's) and it failed to boot
[Android General] wyndyll2:
I have a vb meta, I found on another thread within this one, I lost the link though. Will post when I can find it again but you may be able to find it foryourself inthis thread. All th

It is with deep sadness that I'm reporting the passing of our friend and colleague Viva La Android R.I.P. aka Shane. He asked me before he passed to let his users know how much he appreciated your support for what he loved doing on XDA.

I will miss my friend very much.😑

[Android General] Androxilogin:
Honestly, I don't remember. It's been a long time since I messed with it and directly afterwards, the one I was messing with got a cracked screen. It's still in the process of uploading, but I'm uploading all that I had collected for this project here. The file, Scepter 8 Unlock & Root includes the old batch script I threw together to get mine going.

Sorry to hear of Viva La Android's passing, everyone. He seemed like a really nice guy.
[Android General] demsd:
I'll see what I can make of it. Either way, I appreciate you taking the time to upload the files.
[Android General] demsd:
Just an FYI, in case anyone else asks, it appears to be Android 11. Which would, I suppose, make it Gen 1.

Great guide @Viva La Android. Thank you @EmmaDearest for the pre-boot image.

@Viva La Android I followed you post on #18 the tablet is much snappier.

Just like @13lack13ox wrote, I was unable to choose kyber as the I/o scheduler.

I also didn't see "ZRAM and increase to the maximum of 1000 MB."
[Android General] 13lack13ox:
Yeah, however i resorted to using the kerneladuitor that I am used too by Grarak (open source), to set some settings not available in the editor you provided. Still working out how to change the IO scheduler. Got the z ram setting changed.
[Android General] 13lack13ox:
delete this cloned reply >.>
[Android General] Viva La Android R.I.P.:
Yeah Kernel Toolkit is a bit outdated and has minimal functionality on newer Android versions. I, too, like Kernel Adiutor and use the variant called Kernel Adiutor-Mod on some devices. It supports KCAL advanced color control as well as LMK RAM presets. I've had some issues with it on newer Android versions regarding settings not applying on boot and CPU load not registering.

On the TWRP, I'm hung up on a snag. The /userdata and /vendor partitions are not being decrypted by TWRP using the default key. Thus, the partitions won't mount properly. I've even disabled force encrypt in the fstab file but TWRP seems to be reading the encrypt flag from another source. I am reading over my debug logs and I've reached out to Dees-Troy over at TeamWin for guidance. As far as the ROM, it's fully ready and zip archived into TWRP installable format. But it's not of any use without a working TWRP.

So you weren't able to change the I/O scheduler?
[Android General] 13lack13ox:
Nope options just don't seem available. Might try some scripts to read what its set at, and attempt to change it that way.
