I have a question, can anyone confirm that there is sound after you connect to some bluetooth receiver? On lineage-17.1-20210808?

Because it looks that its not working.

I think vendor needs to stay, that may be the reason why your rom is not booting.
Try deleting system_ext instead. I have product and system_ext deleted, with vendor kept intact.I

I reflashed super.img and the system booted fine

i erased product and system, and flashed lineage 17.1 with no issues BUT it still wont boot, goes to bootloader, i did not use
fastboot --disable-verification flash vbmeta vbmeta-sign.img

because fastboot getvar is-userspace = yes.

so im gonna keep trying to see if theres something i might have missed

i went back used commnad

fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta-sign.img
then i flashed lineage 17.1 and it booted to black screen not even bootloader, so i reflashed stock vbmeta via RD and it boots back to bootloader

i tried these commands with oem vbmeta and custom vbmeta.img and used fastboot -w after evey flash and it does not boot
fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta-sign.img or vbmeta custom
fastboot --disable-verity flash vbmeta_a vbmeta-sign.img or vbmeta custom

Lienage 17.1 is A10 and your tablet comes with A11, right? Maybe its not compatible with A10. Why not try lineage 18 or 19?
( In my experience there is no need to touch stock vbmeta when flashing Gsi.)

that is a possiblity, alot of my emulators dont work with anything higher than A10. so thats why i prefer to use A10 even if theres a chance to extract iplay40 system.img A10 into my device i would do that

i also went ahead and erase the system_ext from the stock super.img and it resulted in a bootloop.
I just flashed the iplay40 system.img on my device it and goes into a bootloop :(

do you know if lineage 18.1 fixes the folder access to apks that google has restricted?

is it possible to unpack the A11 super.img that contains product/system/system_ext/vendor/ and just repack it with A10 product/vendor/system?
Problem is, there is no A10 FW for your device if I understand correctly. AFAIK A10 GSI does also need a compatible vendor (maybe even boot..?) partition to work, which you would find in a stock A10 FW, If there would be one for your device. Vendor (and boot) for A11 just might not be compatible.

ASOP phh system-roar-arm64-ab-vanilla.img A11 worked. had to delete logical product partiton to make room but it booted with just flashing it to the system partition after it resized it. I guess im SOL when it comes to A10 on this tablet

but to my surprise the GSI A11 or maybe Phh version of A11 as lifted the storage restrictions to the emulators so i can acutally find the files on need from internal storage i havent tried sd storage yet.

heres my link i used to get GSI's

Hi guys, today I screwed up, I had a lineageos rom on my iplay40 with magisk and I made the mistake to update from magisk23 to magisk24.1 through the app which brought me to not be able to boot the device again and stays like the pic attached.

I can't go to recovery or fastbood mode either so I don't really know how to move forward, pressing power+up or down just resets the tablet. I have the program called ResearchDownload and the .pac file with the firmware but I think I'd need to enter fastboot to flash the firmware again. Do you think it could be saved?

You need to switch device off, to use it with ResearchDownload

Thanks, indeed it needs to be that way, I confuse myself with some processes with the few devices but I had but to recover that you need to power of and press down while connecting to the tool with the .pac file loaded.

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
ro.product.product.name=iPlay_40

I'm trying to get the android 12 gapps .img to work but I don't know how to unpack the img file and pack it again. Any advice in what to do? Is there any software to make it easy? I've found ImgBurn to turn a folder into a .img I don't know if I'm going well here. If I'm able to edit the system-squeak-arm64-ab-vndklite-gapps.img I'll post it here so other people can just flash it through twrp and get android 12 with gapps. For now I got vanilla a12 but it's quite unusuable for me. Or if somebody else has it I would really appreciate it they uploded it.

Also, a separate issue, I'm also trying to install the last recovery you uploaded, I still use the twrp 3.5.1 I think it is. I'm trying to use your utility but I can't flash vendor after going into adb reboot bootloader.

tools\fastboot flash vbmeta vendor\vbmeta.img
tools\fastboot flash vendor vendor\vendor.img
tools\fastboot flash recovery vendor\recovery.img
tools\fastboot flash boot vendor\boot.img

If I flash everything except vendor the twrp seems to boot but just stays with the twrp logo and twrp doesn't start. Any ideas?
i already made firmware in sparse_dat based on latest aosp12 using https://forum.xda-developers.com/t/linux-free-superrs-kitchen-v1-2-1-5-01-08-2022.3597434/ for t1020s , but I can't get adb to work to capture logs.

Alright thanks a lot, hope it can advance, for now I'm trying to flash gapps to a12 but I'm getting this error attached with bitgapps, and after trying nikgapps tells me "Looks like storage space is full!". Am I missing something?

The problem is in the size of the gsi image, I advise you to flash firmware containing gapps.

Then I would need to get the v402 system-squeak-arm64-ab-vndklite-gapps.img and modify those 3 build.prop no? I'm obviously not experienced with this and I find it a little frustrating how I can't find any software to easily unpack and pack the .img file, those modifications are quite straight forward, I feel I'm so close to have gapps working on a12 on the iplay40 but I'm so far away. Otherwise I'll just go back to a10. Anyway thanks for eveything, I wouldn't have gotten here without reading and rereading all your posts today.

PD:Maybe resizing the gapps img file to make it bigger would make it possible to flash gapps? Or am I making up stuff here?

For gapps to work, you need to change the data that is in the build.prop file in the vendor

    I have tried the iplay40 utility from @AllexBast and most of it seems to work, but when fastbootd is opened it gets stuck on "waiting for any device" that might be a driver issue but where could I find the fastbootd drivers ? everything else works, adb fastboot (bootloader) etc, just not fastbootd
    I own a standard iplay40 (T1020S)

    ps : I checked, I did install at least all the drivers required for the stock flashing tool and i installed these https://developer.android.com/studio/run/win-usb
    Almost like in this video, but the name of the unknown device will be different.

    So, I found a way to install the driver but that was kind of weird, I needed to modify the inf file of the driver to add my vendor ID to the driver's database, the driver installed properly after doing this

    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.

    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.

    bench1.jpg


    gb5-1.jpg


    gb5-2.png


    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.

    storage1.jpg


    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.

    YouTube.jpg


    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.

    video.jpg


    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.
