I was able to get everything working, now i just have two main issues.
ADB doesn't seem to be working, in the magisk log i can read something related to it :

"opendir: /data/adb/service.d failed with 2 : no such file or directory"

the second issue is magisk related, it seems like the version of magisk in the boot is magisk 23 while the app is magisk 25 so it keeps asking me to patch the boot image but i know that if i do the tablet won't boot properly
You can update magisk without problems. adb not working i dont know how to fix it

I need help
I unlocked my boot loader and succesfully installed TWRP but after some work trying to install a gsi it's now stuck in a boot loop.
ADB and fastboot aren't recognizing the device and it only pops up sometimes in the device manager as an unrecognized device...
I tried booting into recovery mode but that won't work either.
It gives me the the message that it is unlocked but I don't think it's fully booting because normally it would tall me afterwards that it skipps some verification or something.
I searched for days and even tried to flash the firmware but the tool won't recognize the device either.

Download the latest official firmware and Spreadtrum Upgrade Tool and Guide.rar. There is a description of how to flash

In order not to flash the stock firmware every time, sometimes it is enough to flash the stock boot.img through the research downloader flasher and the tablet will reboot into fastboot mode. Then we reboot into twrp with the help of the command
fastboot reboot recovery. In the recovery, we restore the zero vbmeta and again flash the gsi image. gsi assemblies do not all work on this tablet.

Hi. I own iPlay40 non-h (T1020S_V1.0_20210525). Automatic updates stopped at November 2020 Android 10. Is it possible to install Android 11 on this model?

Found an easier option to disable encryption on the stock firmware for the t1020s tablet.
The utility will do all this.
It will flash the modified vendor.img at once to disable encryption, zero vbmeta, twrp and a patched boot via fastbootd.
Conditions:
The bootloader must be unlocked. Enable USB Debugging. There must be a stock firmware. The drivers for fastbootd must be installed.
Then from fastbootd you need to go to recovery using the menu. And in the recovery, make a hard reset and reboot into the system. All data will be erased!!!
The bootloader can be unlocked from this utility if you copy signature.bin to the utility folder.

Added Utility-T1020S_v02
The utility has a new twrp. Source https://github.com/allex2/android_device_alldocube_T1020S
Will this work on the Alldocube kPad? I know it's a different device, but they're alike in many ways

    I still have no luck with the information from this link.

    They mention an APK, the "SpreadTrumTools-20200317.apk", but I can get this APK from nowhere. I tried several links to some Japanese (?) online storage, but I only manage to download some exe files, and obviously I don’t download them. Without it I cannot generate the signature.bin and do the rest of the steps.

    I tried this method from the Hovatek forum and I still don't be able to unlock the bootloader.

    When I try the command "fastboot flashing unlock_bootloader signature.bin" it always fails.

    I have tried several ways to get the signature.bin, even using a live Ubuntu distro (and the hassle to learn how to do all of this in Linux).

    After a large of hours getting nowhere, I think I will give up to unlock the bootloader to root this tablet.

    If somebody can give any help I'll appreciate, maybe a link to download the SpreadTrumTools-20200317.apk, or other solution to unlock the bootloader.

    And If possible, somebody installs the CPU Monitor app and verify if the cpu is almost all the time at 80% plus as mine.

    I was able to enable Gaps on build system-squeak-arm64-ab-vndklite-gapps.img.xz

    Need to change
    /system/build.prop
    /system/system_ext/etc/build.prop
    /system/product/etc/build.prop

    These lines

    ro.product.product.brand=Alldocube
    ro.product.product.device=T1020S
    ro.product.product.manufacturer=Alldocube
    ro.product.product.model=iPlay_40

    TWRP and ModSuper for gsi only for the IPlay40 (t1020s) model

    You need to unlock the bootloader https://forum.xda-developers.com/t/...-some-minor-compromises.4212541/post-85850877

    install Disable encryption in Utility-T1020S_v01
    You need to download:

    ModSuper for gsi https://forum.xda-developers.com/t/...-some-minor-compromises.4212541/post-86307695

    In addition, you will need a micro SD card in order to move these files to it.
    Copy the unpacked files mod_super_gsi-v1.img and gsi rom to the memory card

    restart adb recovery
    install for section super mod.super.gsi.sparse.v2.img
    wipe factory reset
    reboot recovery

    install for section system gsi android 10 or 12 arm64 a/b pre-unpack from archive https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

    restart system
    configure gsi rom
    restart adb recovery
    install gapps android 10 arm64 pico https://opengapps.org/ or android 12 https://www.pling.com/p/1462970/
    restart system

    Did you manage to get any of the Android 12 to run alright?
    This is the best build 12 https://github.com/phhusson/treble_experimentations/releases
    You can add a line to the file debug.sf.latch_unsignaled=0 in /system/build.prop. This removes graphic artifacts, but not all
    Used assembly system-squeak-arm64-ab-vndklite-floss.img.xz alternativ gapps
    Very fast assembly

    After flashing gsi 12, format data - yes and rebooting, twrp stops working

    To change something in the system sections, vndklite assemblies are needed

    Solid performance

    STATS.jpg


    The Alldocube iPlay 40 is powered by Unisoc’s T618 processor, which has an octa-core CPU (2 Cores of Cortex-A75 clocked at 2.0GHz and 6 cores of Cortex-A55 clocked at 2.0GHz) and ARM’s Mali-G52MP GPU.

    comparison.png


    This chipset was released in 2020 and built on 12nm process, so it is relatively new, and it offers better performance than MediaTek’s P60 or Qualcomm’s Snapdragon 66X, which are the most commonly used SoC. In budget and midrange tablets. There’s also 8GB LPDDR4 RAM inside the slate to handle multitasking.

    ANTUTU.png


    The iPlay 40 has easily beaten other budget tablets in Antutu and Geekbench 5. Even the Teclast M40, which is powered by the same Unisoc T618 chipset, scored significantly lower than the iPlay 40 in both tests.

    3DMARK.png


    In the GPU-focused 3DMark Slingshot Extreme test, the iPlay 40 was also returned with decent scores.

    ANDROBENCH.png


    The storage inside of the iPlay 40 is relatively slow. The Sequential Read speed is only 106.27mb/s in Androbench’s readings, falling behind most other entry-level tablets including Alldocube’s very own iPlay 30, which was released three months ago. But in comparison, Teclast uses even lower-quality storage in both of their M40 and P20HD.

    In the real-world use, the Unisoc T618 processor actually offers more than enough horsepower to drive the tablet for the tasks it is intended for. The iPlay 40 is smooth and responsive most of the time, I had no issues watching 4K YouTube videos in Chrome, with many other image-heavy webpages loading at the same time. The slate is also capable of keeping many big applications running in the background, thanks to its whooping 8GB RAM.

    However, the iPlay 40 isn’t the best video decoder, as it scored only 827 in Antutu video tester, but for those normal video formats, you always have the choice to use software decoding. I’ve tried many clips and the slate can play all of them smoothly.

    DSC08581.jpg


    Gaming should not be your main reason to buy a tablet. With that said, the iPlay 40 can run most games installed from Play Store without issues. I tried Asphalt 9, PUBG and Arena of Valor, all of them can run smoothly at moderate settings.



    Superb connectivity

    DSC08538.jpg


    The iPlay 40 supports dual-band Wi-Fi, Bluetooth 5.0, 4G and full phone functionalities. It won’t have fancy features like 5G and WiFi-6, but we don’t expect it to.

    The 128GB internal storage should be sufficient for most users. For those who need more, the tablet supports a TF card of up to 2TB!



    Basic cameras

    DSC08616.jpg


    There are two cameras on the iPlay 40, a front-facing 5MP camera and an 8MP main camera. Those cameras can be useful for unlocking, video-chatting, and scanning QR code, but you won’t want to “archive your life” with them. Even in perfectly-lit conditions, most photos I took with the main camera were either over-exposed or under-exposed, and there wasn’t much life to them. In low light, the photos were simply horrible. In an era when most entry-level smartphones come with dual or triple camera setups, there is really no place for tablet photography.



    Subpar battery life and charging speed

    BATTERY-COMPARISON.png


    The Alldocube iPlay 40 houses a 6000mAh Li-Po battery, smaller than the capacity of most of its peers. Even with a more power-efficient processor, the iPlay 40 still only gives me around 7 hours’ screen time on a full charge.

    BATTERY-LIFE.png


    With display brightness and speaker volume both set at 50%, the iplay 40 lasted 7 hours and 55 minutes in our battery rundown test, where we played a 1080P video on loop.

    This iPlay 40 doesn’t support any form of quick charge. The supplied wall charger is rated 10W (5V-2A), a full charge (0%→100%) takes about 4 hours. In comparison, the Lenovo Tab P11 comes with a 20W QC3.0 charger, while the Smasung Galaxy Tab A7 supports 15W charging.



    Verdict: an all-around tablet with some minor compromises

    The Alldocube iPlay 40 isn’t designed to break any new grounds, but it is an Android tablet which gets a lot of essential things right. It has a sharp and colorful display, which makes it ideral for video streaming, web-browsing and even light gaming. The T618 processor offers more than enough power for everyday tasks. 4G and phone functionalities means the tablet can be a serviceable phone whenever needed.

    The absence of a fingerprint reader, slow storage and low battery capacity could all be potential deal breakers for many, but for a tablet priced as low as the iPlay 40, it’s really unfair to ask for perfection. With UFS 2.1 storage, higher quality speakers and much, much better cameras, the Lenovo Tab P11 is still a superior piece of tech in many aspects. But if horsepower is on top of your priorities when choosing a tablet, you won’t get anything better than the iPlay 40 in the same price range.
