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
[Device Reviews and Information] AllexBast:
Install the driver manually: select from the list of available Android Composite ADB Interface. The installer will display a message that it is not compatible with this device, select Yes
[Device Reviews and Information] seledreams:
usually it didn't just tell me that it wasn't compatible with the device, it told me no driver for the device at all were found but i was able to fix it by modifying the inf file to add my vendor id and then install it from windows in a mode where it didn't hash check drivers

it now did work and i was able to run your tool
[Device Reviews and Information] AllexBast:
This will be the best option. During a normal installation, it often flies. Have to reinstall
[Device Reviews and Information] seledreams:
now though I'm faced with an issue after running your tool as it did install twrp and co but after rebooting i don't know how i'm supposed to go to twrp, power + volume up doesn't seem to work
[Device Reviews and Information] AllexBast:
Did you follow my instructions? When you first booted into TWRP, you had to execute format data - yes. Then immediately reboot back into twrp and install the gsi firmware.
[Device Reviews and Information] seledreams:
the issue is twrp stayed stuck on the teamwin splash screen
[Device Reviews and Information] AllexBast:
Sorry. That's my fault. It was necessary to use the version 1 utility. There is another twrp that should work on an encrypted disk.
[Device Reviews and Information] seledreams:
that's the screen it's stuck on after running Utility-T1020S_v02
[Device Reviews and Information] seledreams:
oh i see, i'll check
[Device Reviews and Information] seledreams:
I just tried v1 as well it also stays stuck on the teamwin logo
[Device Reviews and Information] AllexBast:
try the command adb reboot fastboot then extract the twrp.img file from utility number 1 and flash with the command fastboot flash recovery twrp.img fastboot reboot recovery
[Device Reviews and Information] seledreams:
I did try as well, it is still stuck on the teamwin logo

to make sure, it's using twrp 3.6.0_11-0

it's the recovery.img bundled with v1
[Device Reviews and Information] seledreams:
i can't tell if it's related, but when i launch your program, it ends up leaving my tablet in fastbootd at the end and when i launch fastboot reboot recovery it always gives me fastboot: usage: unknown reboot target recovery

so i end up using the boot menu of your application instead
[Device Reviews and Information] AllexBast:
I understood the reason. When you get into fastbootd, you need to go into recovery from it and make a format. Then reboot.
[Device Reviews and Information] seledreams:
I ended up figuring it out, now it's working, I also got the super img flashed, i'm not really sure tho now which gsi would be the best to install now, I tried to install lineageos 19 but it says that its size is too high for the system partition so...
[Device Reviews and Information] AllexBast:
Flash for twrp https://xdaforums.com/t/alldocube-i...-some-minor-compromises.4212541/post-86307695

Reboot to recovery

Flash gsi

Install magisk

Reboot

I recommend this build

I followed the exact same steps and installed the exact gsi, but I end up with a bootloop

edit : i was able to make it work by doing a wipe factory reset after installing the super image
[Device Reviews and Information] AllexBast:
Sorry, I forgot to specify the date format. But it's in the instructions. I had an early version of twrp that ran on an encrypted drive. But apparently I removed it. I haven't used a tablet for a long time, so I might be wrong.
[Device Reviews and Information] seledreams:
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
[Device Reviews and Information] AllexBast:
You can update magisk without problems. adb not working i dont know how to fix it
[Device Reviews and Information] tempterminal:
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.
[Device Reviews and Information] AllexBast:
Download the latest official firmware and Spreadtrum Upgrade Tool and Guide.rar. There is a description of how to flash

Alldocube iPlay40(T1020S) firmware download

www.alldocube.com
[Device Reviews and Information] AllexBast:
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.
[Device Reviews and Information] jeryll:
I just found out that if you enable in Phh Treble settings >> Misc features >> Force-disable A2DP offload, after tablet reboot BT headphones actually works! Now I can finally use GSI ROM as a daily driver...

[Device Reviews and Information] vorks:
hi guys, some help needed. I have an Iplay40 and its around 13 months old. This morning it suddenly shut down and all I can do is just boot up to the ALLDOCUBE logo and that is it. I cant get into recovery no matter what i do, just keep rebooting into alldocube.

Then I download the spectrum + firmware and tried to reinstall stock firmware. However it keeps failing at repartition: UB1132 operation failed

Now i even lose the boot logo. Any help? Cant believe it died so fast :(

p.s: the only issue i had before this was that SIM2 didn't work but i wasn't too worried about it.

Hello. I tested firmware gsi A13. Very good firmware https://github.com/ChonDoit/treble_cherishos_patches/releases . Problems with bluetooth and adb remained. But now you do not need to fix build.prop . gaps are synchronized only with the vendor and are initialized correctly.

Hello all,

I've tried to upgrade the linage 17.1 Gsi to A13 CherishOS and I got a bootloop. The problem is that I'm not able anymore to enter in fastboot or TWRP with the buttons combinations... Only bootloop😢

Do you have any idea to recover this?

What did I do wrong?

Thanks
[Device Reviews and Information] akaloith:
I did not find GOOD analytic instuctions to install A13 on alldocube iplay 40H and i am afraid i am gonna mess up :(

so keeping my stock rom till i find them
[Device Reviews and Information] AllexBast:
You will have to flash the stock firmware as described on the official website, and then re-use my instructions.
[Device Reviews and Information] arct0sk:
Thanks AllexBast :)

I found your instructions and your utility. Wonderful work.

A13 works amazing.
[Device Reviews and Information] akaloith:
also work for

Alldocube iPlay 40H ??​

this "begin to erase user data...." takes too long....​

it worked but everything else is also for 40h ????
[Device Reviews and Information] AllexBast:
The iPlay40s tablet model is different from the iPlay40h. You can flash the gsi firmware in the standard way via fastbootd. An unlocked bootloader is required.

adb reboot fastboot

fastboot reboot fastboot

fastboot delete-logical-partition product

fastboot flash --disable-verity --disable-verification system gsi.img

fastboot -w
[Device Reviews and Information] akaloith:
my 40h had an option in developer "oem unlock"

but i unlocked the bootloader as it was said in the instuctions for 40s

1) I am ok? I could just turn this on to unlock bootloader?

2) so only unlock bootloader is required? 40h is easier than 40s ?

3) which A13 img should i install for 40h? direct link?

4) fastboot -w (with a space i suppose? )
[Device Reviews and Information] AllexBast:
Unlocking the iPlay40h bootloader is no different than iPlay40s. I don't have an iPlay40h tablet model, so I can't say which firmware is right for you. To roll back to stock, you need exactly this software https://www.alldocube.com/en/firmware/alldocube-iplay40ht1020h-firmware-download/ . Space required in fastboot -w command
[Device Reviews and Information] akaloith:
1) so as far as i can understand 40h is easier to install custom rom, needs less steps (just unlocked bootloader) from 40=40s? why is that?

2) iplay 40s = iplay 40 ? iplay 40 & 40h seem the same except from the stock android, 40h comes with 11, 40 comes with 10 and 6200mah battery from 6000mah on 40

3) maybe try this? CherishOS_A13-arm64-bgS-slim_20221121.img ?

what works on iplay 40 should work on 40h, they seem the same hardware

No need to invent any compatibility between these different tablet models. Perhaps there is some kind of partial compatibility in the hardware, but it is definitely not in the software.
[Device Reviews and Information] akaloith:
yes but this cherishos for example is not specific for iplay 40

its a generic rom for "compatible" models

have you found any other rom for iplay 40 that works ok?
[Device Reviews and Information] akaloith:
adb reboot fastboot

goes directly to fastbootd

fastboot devices and i see no devices so i dont think there is a connection with the pc

not even fastboot reboot works

I just unlocked bootloader on 40h, need to do more?
[Device Reviews and Information] reg66:
Is there a specific TWRP version required to flash A13 GSI? Cheers
[Device Reviews and Information] reg66:
Does this include GAPPS? Cheers
[Device Reviews and Information] reg66:
@AllexBast So I flashed your recommended A13 GSI (which I'm loving BTW, cheers) but now I can't load twrp, it just loops...

I'm guessing there's no way to access twrp once A13 is flashed as twrp is outdated for our device (have disabled all screen/system locks etc), is that corrcect? I suppose I would need to flash stock again and start from scratch to get twrp working again, right?
[Device Reviews and Information] AllexBast:
Most likely you failed to disable encryption. Try going to settings - system - factory reset - clear all data. Or try to repeat the whole process again.
[Device Reviews and Information] reg66:
Nope, have disabled encryption definitely this time. Even before settings screen lock etc and booting to twrp, it just bootloops twrp screen. I suspect it's because twrp isn't compatible with A13.

Assuming you're still running the CherishOS A13 rom, can you try rebooting to twrp to see if it works for you...?
[Device Reviews and Information] reg66:
@AllexBast or anyone else running gsi, maybe I'm blind in the settings, but for love of god someone tell me how to remove this ugly task bar, quick icons bar thing. Permanently frozen I mean, not minimised. I know how to freeze it, just don't know what it's called... Cheers indeed and sorry if this pic comes out massive on my phone... As you can see from my other icons, I like things plain and simple!!

EDIT: ok so it's part of CherishLauncher... But I can only make the icons tiny and to match my other icons...

ANY way to disable it, will disabling Cherish Launcher cause issues with Nova?

EDIT 2: for anyone else bothered by it, disabling CherishLauncher completely kills the home (swipe up gesture), as a work around i'm using fluidnavigation from playstore. all good now and i can sleep easy lol... and if you do disable it, be sure to set alternative launcher first as default, dunno what'll happen if you're launcherless!!
[Device Reviews and Information] Danacy:
Absolutely amazing that GSI is a possibility on the iPlay 40! I have tried to look for the entire procedure and files but I am not confident. Do we already have a step-by-step plan I could use?

[Device Reviews and Information] Danacy:
Hi!

Can I about your experience with GSI so far? Does it do updates?
[Device Reviews and Information] reg66:
Hi bud. Haven't really used the tablet much since flashing gsi. Can't really say how it is or what's working etc.

As far as I am aware, gsi will always need to be updated manually as it's not service specific
[Device Reviews and Information] silviu.butnariu:
did you install custom rom on iplay40s or h? I have iplay40h and I don't know how to install custom rom, can you help me please?

Thank you!
[Device Reviews and Information] reg66:
'S', sorry bud... not sure about your H
[Device Reviews and Information] Danacy:
OK, thank you for your reply. I am struggeling in the procedure, can I ask you how you did it? I really want to give it a try
[Device Reviews and Information] reg66:
Sorry bud, your H version may have different hardware and therefore the proceedure may be different. I wouldn't want to give you bad advice and brick your device, but I'll have a quick google for you...

EDIT: thought you were the guy with the above H version... TBH I did a lot of tinkering with the tablet that night of flashing GSI. I'll have a think and if I can recall I'll write a post soon (sorry, bit busy just now...). Just to confirm though, you have the S version, right?
[Device Reviews and Information] Danacy:
I have the first one, iPlay 40. Still, procedure should mostly be the same. Just different firmware etc. Any help would be appreciated.
[Device Reviews and Information] reg66:
Ok pal. Will see what I can do. There's two versions of the same iplay 40, the (T1020)S and H versions. Mine is the earlier model (S), so yours should be too... you can check by installing device info HW and under 'system' it should say under 'fingerprint' whether yours is S or H

Have you unlocked your bootloader already?

Also, before flashing any rom i'd recommend downloading the orignal rom/firmware from here. Have that on standby in case you need to start from scratch. You'll need to extract the .rar file (did this a long time ago so not sure if you need to extract more than once) until you have a .pac file. Last rom update was/is from 26/05/21.

Will try and report back tomorrow (y)
[Device Reviews and Information] Danacy:
I installed the app and can confirm I have the T1020S. Bootloader not unlocked yet because I was too uncertain if have the procedure correct.
[Device Reviews and Information] reg66:
Ahh, bootloader i'll have to have another read up on, it was ages ago i did mine. Hopefully the process should jog my memory, don't think there was any issue though, pretty straight forward
[Device Reviews and Information] reg66:
Cool. Just going through the install process again etc etc and writing you up a guide. May head to bed soon (3am here!) but will post bootloader instructions soon to keep you going!

BTW, Having gone over the tablet again, that app I mentioned wasn't necessary. The device model/variant can be found under settings/about phone/build number!!
[Device Reviews and Information] reg66:
Ok bud, bad news is I can’t recall the exact procedure, good news is I’m gonna do everything from scratch. Will go through the steps for unlocking bootloader but obviously I’m unlocked already so can’t say for sure whether my instructions will work…

Pre-requisites;

Download and extract all folders etc from this link, it includes drivers, unlock bootloader folder =[adb fastboot folder (copy to root of C drive ideally)] plus [spreadTrumTools apk for unlocking bootloader], SPD factory tool for flashing, TWRP files, latest factory firmware etc etc…

Install USB drivers from downloaded and unzipped folder from Mega by right clicking DPInst.exe and choosing 'run as administartor'

Plug device into PC via cable in USB 2.0 port. Enable developer options, go to settings/about phone and at the bottom tap on build number 7 times. Go to developer options under settings/system/advanced and BOTH ‘enable OEM unlocking’ and enable ‘USB debugging’ – click allow on device screen when prompted to allow USB debug connection

From the unlock folder (after unzipping it) that you downloaded from Mega, copy the SpreadTrumTools.apk to your device and install it.

On your PC, copy the unzipped adb fastboot folder to root of C drive (ideally). Open it and double click on cmd-here.exe which will automatically open your cmd to opened folder.

Type (or copy and paste) the cmd ‘adb shell getprop ro.serialno’ without the ‘s and hit enter. Note the serial number for your device.

Open the SpreadTrumTools app on device and allow permissions. Where it says ‘unknown’ delete and input the serial number you got before. Click ‘generate’.

Open file explorer app again and navigate to root of main internal storage. There’s your signature.bin file for unlocking your device.

Copy signature.bin file to adb fasboot folder.

Go back to your cmd window and type ‘adb reboot bootloader’. Hit enter to run cmd.

Wait for the tablet to boot into fastboot, if for any reason boots into fastbootd, navigate to reboot to fastboot. (‘fastboot’ will be displayed in small font in top left of screen).

In cmd window run the cmd ‘ fastboot oem get_identifier_token’ followed by ‘ fastboot flashing unlock_bootloader signature.bin’

Once those cmd’s have been run you should see the same as image (copied from @ar_aja)

See image for final instructions

Thanks mainly to @ar_aja and @AllexBast without those guys none of this would be possible without a lot more legwork, if at all. Thanks to anyone else for any other info I have used, sorry if I forgot to mention you…​

Also note, I tried to install magisk 25.2 delta and magisk 23.0 the usual way but got boot loop. Will report back with instructions for root, if needed?

Also, if at any stage of anything you get bootloop, don't panic and report back... nearly everytime you'll be able to just flash parts boot etc img's or failing that the complete stock rom using ResearchDownload and instructions provided in mega link
[Device Reviews and Information] Danacy:
How did you manage to get TWRP to work actually? In step 13 it will not go to TWRP automatically
[Device Reviews and Information] reg66:
What exactly is it doing? Is the utility V2 software not recognising the device anymore and so the device just doesn't respond?

Did you click 'allow usb debug...' connection after enabling USB debugging in dev options?
