Refresh my memory on that Bubba. I don't recall posting any MicroG builds on this thread. If I posted a link on the topic, it was merely a general info reference. Repost a lnk to the MicroG you are referencing, though, and I'll be able to give you some more info on it regarding signature spoofing.
[General Topics] Bubba The Hack:
I did not mean to confuse you. I was wanting to install MicroG to take the place of google play services that an app needed. The instructions simply stated that the build need to have signature faking available. That's all. ;)

Just wanted to know if it was there.
[General Topics] Viva La Android R.I.P.:
Glad to hear it.
[General Topics] Viva La Android R.I.P.:
Via fastboot mode, you typically only.need to flash boot.img (both slots) and super.img.
[General Topics] Viva La Android R.I.P.:
The super.img and boot.img are both from the firmware package you just referenced
[General Topics] Viva La Android R.I.P.:
If you want to restore with fastboot, again, you generally only need to flash super.img and boot.img. Yes the ImgRePacker Tool I linked will extract all partition images from the firmware .img archive. Use the instructions I outlined with ImgRePacker.
[General Topics] Bubba The Hack:
@Viva La Android, I forgot to give you the link, so here it is. Micro-G

Please note Step 1. Thanks.
[General Topics] Viva La Android R.I.P.:
The QLink Scepter 8 stock ROMs should have no problem supporting signature spoofing once I add the system patches needed

Some ROMs with custom overlays, such as LG UX 10.0, have issues with signature spoofing that can be resolved by particular mods to the OS. Because the Scepter 8 firmware packages all include near Vanilla builds of Android 11/12 Go Edition, signature spoofing shouldn't be a problem. I would recommend giving it a try just as soon as I make the needed patches to the OS

I will modify a Scepter 8 stock ROM to include microG as a substitute for Google Play Services, which can be installed via fastboot.

Bubba, you are running Android 11 Go Edition, correct? Of course, if you want to go ahead and try it, just install the MixroG.zip as a systemless module via Magisk.

Here's a link to the latest beta and stable NanoDroid microG module builds.

Nanolx.org Downloads Archive

It is my understanding that the NanoDroid modules include an OS patcher for spoofing support.
[General Topics] Viva La Android R.I.P.:
@ScarletWizard here are the super.img and boot.img from the Android 12 Go Edition firmware build 01_20220711. I archived the images to .zip format, so just extract the archive once downloaded.

V01_20220711 super.img & boot.img

And I do believe I know the cause of your device recognition issue. The 15 Second ADB utility actually installs unsigned drivers on your Windows computer. Unless you have test signing enabled or driver signature verification disabled, the drivers will not install on 64-bit Windows 10 or Windows 11. To install the unsigned drivers:

Click your Windows Start icon;

Open the Settings app;

Select System, then Recovery;

Select Advanced Startup;

Your PC will boot into Recovery mode with options on a blue display.

Select Troubleshoot, and then select Advanced Options, & Startup Settings;

Click the Restart box;

Select Option #7 - Disable Driver Signature Enforcement.

Your PC will now reboot to the Windows OS like normal. Now install the 15 Second ADB utility.

@ScarletWizard, this should resolve your driver issues and enable recognition of your device while using the Allwinner firmware flashing tools
[General Topics] Viva La Android R.I.P.:
@Bubba The Hack, are you wanting a stock ROM configured for microG as a replacement for Google Services Framework? I can work on that and get it ready if you do. I'm sure other members would also use microG in lieu of Google's proprietary framework on the stock OS.
[General Topics] Viva La Android R.I.P.:
Partition Images v01_20220711

I extracted all of the key partition images from the v01_20220711 firmware package, archived the images into a .zip file, and uploaded it to my cloud hosting. For anybody wanting to flash firmware using fastboot, these images should do the job .
[General Topics] Viva La Android R.I.P.:
@ScarletWizard ,all you needed to do was disable driver signature verification and install the 15 Second ADB tool.
[General Topics] Bubba The Hack:
@Viva La Android , Yes, I am wishing to have as clean an OS as possible with no attachments to google at all. Any help you can give would be greatly appreciated!!!!!! I did not want to burden you with that, but am sure that there are millions of us who want that but can't afford PurOS.
[General Topics] Viva La Android R.I.P.:
So are you wanting microG and all Google apps and services removed? Or just microG replacing Google Play Services and leaving Google apps in place? Let me know exactly what kind of setup you want and I'll get to work
[General Topics] Bubba The Hack:
Wow! What an offer. How can I refuse.

I would like nothing google at all. As long as the tablet functions as it should hardware-wise.

BTW, I don't use it as a phone. I just use the WiFi function when close to an access point.
[General Topics] Viva La Android R.I.P.:
No problem. I'll de-Google the OS entirely and replace essential services such as location with open source alternatives. Shouldn't take me long. But, keep in mind that the OS is a Google Go Edition build so a couple of services may be tricky to remove. I'll keep you posted.
[General Topics] Viva La Android R.I.P.:
It's a reset button. It forces the tablet to power cycle. It's a good way to force a reboot if you ever get stuck in BROM/FEL mode, for example.
[General Topics] Viva La Android R.I.P.:
@Bubba The Hack, just to clarify, you are running the v9 Android 11 (Go Edition) firmware build, correct?
[General Topics] Bubba The Hack:
Build number Scepter_8_Tablet_V2.0_20210423

Android version 11
[General Topics] Viva La Android R.I.P.:
Wow. You have V02 of the Android 11 Go build? That's an old one. Before flashing the ROM I'm working on, can you dump the firmware from yours? I would like to have the V02 build from the first tablet model. Do you know how to dump your partitions?

By the way, you'll be the tester for this ROM if you would be so inclined. My Android 11 GE model tablet is broken, so I have no 2ay of testing. I have the de-Googled ROM almost finished
[General Topics] Bubba The Hack:
No, I do not know how. Evidently there has been some updates from when I first started this with you?
[General Topics] Viva La Android R.I.P.:
Well, the most current firmware I have for the old model tablet is v9. I also have the v6 build. So your build is 7 incremental versions older than the v9 build. It seems that Hot Pepper Mobile, the maker of the Scepter 8, rolls out one new build every month. Now that the Android 12 GE model has been released, I'm guessing that the old model is now EOL (end of life) in terms of firmware or update support. In other words, there will likely be no more firmware builds for the old model.

By the way, if you don't mind doing it, I can send you some terminal commands to dump your firmware. I only need your super.img,, bootloader.img, dtbo.img and misc.img
[General Topics] Bubba The Hack:
Sure, just tell me what to do.
[General Topics] Viva La Android R.I.P.:
Great. Thanks. First I need to know your active slot, so I'll know which partitions to have you pull. Connect your device to your PC and boot your tablet to fastboot mode. Open a command window and execute this command:

fastboot getvar all

You will see several lines of text return on the command window. Look for (bootloader) current-slot

To the right of that entry will be the value _a or _b

That's what I need to know, slot _a or slot _b

Thanks Bubba
[General Topics] Viva La Android R.I.P.:
No clue, did you first extract the actual firmware .img file from the compressed archive you downloaded?
[General Topics] Viva La Android R.I.P.:
What OS are you running LiveSuit on?
[General Topics] Viva La Android R.I.P.:
Not sure what's going on there. I just ran md5 integrity checks on.all five firmware packages I have for the Scepter 8. They all check out fine. If you've not tried it yet, use PhoenixSuit v1.10.
[General Topics] Viva La Android R.I.P.:
The Android 11 Go Edition model runs on the Allwinner-A100; the Android 12 Go Edition model runs on the Allwinner-A133.

There are only three proprietary Allwinner flash tools available, four counting PhoenixCard. I have all four listed in the OP. Many members have reported the best results using PhoenixSuit. One good thing about Allwinner is that they are almost impossible to hard brick. I have never heard of one being hard bricked. They use hardware embedded bootloader code to sustain BROM/FEL mode, which is the mode the flash tools use to restore firmware.
[General Topics] Viva La Android R.I.P.:
The answer to the question you just asked.
[General Topics] JovialQuestion:
I'm not sure if you went over this or not. However. I just extracted the .img file with the provided tools. From fastbootD I just fastboot flash super ./SUPER.fex and then fastboot reboot-bootloader .. fastboot flash boot BOOT.fex fastboot flash --disable-verity --disable-verification vbmeta ./VBMETA.fex .. fastboot continue. So if you made a change to your system and now it won't bood and you haven't messed up bootloader or anything. It works for me quite well. For me
[General Topics] JovialQuestion:
If you can extract the image to get the fex files. You can fastboot flash the super and boot img. (unlocked bootloader)
[General Topics] JovialQuestion:
Adb reboot bootloader

[General Topics] JovialQuestion:
There is A hole under power to manually kill power to keypress to bootloader again. Just don't jam on it I broke the metal cap off mine. Light touch.
[General Topics] JovialQuestion:
You need to extract the .rar then with the imgtool in the post. Extract the .img file you will see .Fex files. You need the vbmeta.fex super.fex boot.fex as this is all I have tested via Fastboot. Once you have that and the driver's installed in I used the ones with livesuit in the link. Then you need to keypress into bootloader fastboot. Provided your unlocked.

Fastboot flash boot ./boot.fex

Fastboot flash --disable-verification --disable-verity vbmeta ./vbmeta.fex

Fastboot reboot-fastboot

Fastboot -w flash super ./super.fex

Fastboot flash boot_b ./boot.fex (or your patched boot)

Fastboot flash boot_a ./same image as b

I hope this helps if your cannot get it to go I would follow the standard instructions. This is just how I got it to work. On v02-20220726
[General Topics] Viva La Android R.I.P.:
@ScarletWizard did you try @JovialQuestion's recommendations? Any luck?
[General Topics] JovialQuestion:
I will upload a link for the files I extracted. It just needs to upload .

My internet is slow but it is uploading this is the folder it will be in. It's at 1 gig of 2.33

Just refresh it it will show up.

Also I used windows 7 ultimate edition 32bit cause it's the only windows PC I have. Sometimes compatibility changes per version so not sure if that helps.

I do know that magisk 25.0 + always fails to boot. And 24.3 is the only one that let me mount system tho I could just be doing something wrong lol

[General Topics] Viva La Android R.I.P.:
Indeed. I just now saw your commands that you recommended to @ScarletWizard. Hopefully he's up and going. And thank you for taking the time to help him out. He's had many difficulties trying to get his device restored.
[General Topics] JovialQuestion:
It flashes regardless of changing the extension to .img. In fastboot but you may want it to be .img when working of the files so it easier to patch. So not bad advice just a matter of preference it would flash as a .bin file too.
[General Topics] Viva La Android R.I.P.:
Yeah my experience has also been that both legacy fastboot and FastbootD modes will work for flashing standard firmware images.

Correct @ScarletWizard you do not have to rename from .fex to .img. Fastboot will flash .fex files. You can put faith in @JovialQuestion's instructions. It's nothing to do with right or wrong here. It's just preference. Both ways work
[General Topics] JovialQuestion:
Lol. I am not a windows user. So I honestly have no idea. It's a mini acer laptop that I keep in a drawer lmao 🤣.
[General Topics] JovialQuestion:
I am going to take care of a few things around the house here. Let me know if that helps. If it doesn't I will extract some more and get what I can. It could just be a driver issue or just a bad extraction. Sometimes that happens and it's no one's fault. Just happens from time to time. Can't count how many times over had to flash over and over to discover the PC I was using was corrupting my files or sadly needed to clean my usb port lol. Lucky tho my MinI acer hasn't even been online so. Maybe since this is the only software I have on that PC it has not conflicts.

I was able to flash the super.fex from Bugjagger Premium app and a otg cable so I assume it will work. I'm trying to find a order that will be efficient
[General Topics] JovialQuestion:

[General Topics] JovialQuestion:
./super is the path to the image
[General Topics] JovialQuestion:
Like fastboot flash super C:\Users\cc\download\super.fex or open the terminal in the folder that has the .fex files.

Then fastboot flash super super.fex
[General Topics] JovialQuestion:
But it's sounding like you need to update adb and fastboot. Fastboot reboot-fastboot should work. Try fastboot reboot-recovery then click fastboot
[General Topics] JovialQuestion:
@ScarlettWizard what is the extra frimware img you need. I'm going to extract MDF_AP13_20220607.img and CF_MQ813_Scepter8_SMR_v01_user_20220711.img

It's going to take me a few but I will have those
[General Topics] JovialQuestion:
It's on my mega cloud link
[General Topics] JovialQuestion:
Where is the files located you want to flash. The complete path just open that folder and click file then open command prompt. Then it should look like this.
[General Topics] JovialQuestion:
Oh wait. / is for linux. I'm so sorry. Fastboot flash super super.fex
[General Topics] JovialQuestion:

Everything is so much easier on Linux. ;)
[General Topics] Viva La Android R.I.P.:
Keep in mind, Windows 11 now includes a full Linux subsystem, complete with genuine Linux kernel. Known as WSL2 (Windows Subsystem for Linux II). You can run Ubuntu and other Linux distros right on top of Windows. And, Windows 11 has native support for Android APKs.

And Bubba, I have to get another tablet to work with. I'm having a heck of a time trying to cook up this de-Googled ROM using emulation and no device. I've got two Scepter 8 tablets, and both have shattered display. By the time I pay for a display I could go on eBay and get the entire tablet, new in the box, cheaper. So that's what I'm going to do.

By the way @Bubba The Hack, did you find the active slot on your tablet yet? I was going to send you instructions on dumping your partitions. But I need your active slot to know which to have you dump. Thanks

[General Topics] Viva La Android R.I.P.:
@ScarletWizard, I am wanting to test a theory here. On restoring the firmware of your tablet, I want you to try the first package I have listed under the Android 12 Go Edition heading. Use PhoenixSuit v1.10. If you want to flash it with fastboot mode, I can unpack the firmware and tell you which images to flash.
[General Topics] Viva La Android R.I.P.:
As I explained before, in order to install the correct drivers, which are unsigned, you must first disable driver signature enforcement. This is the case if you are running Windows 11, or a 64-bit build of Windows 10 or 8.1. Are you running Windows 7?
