In principle, it is possible to make a standard pac firmware for ResearchDownload with built-in gsi , twrp and boot magisk firmware. You will only need to unlock the bootloader if it is locked and flash the pac firmware. If anyone is interested in this, I can do it.
[Device Reviews and Information] sphonk0:
Hi Allex I am interested, can you please be so kind and do it?

Thank you very much!☺️
[Device Reviews and Information] AllexBast:
Unfortunately, it didn’t work out for me with the crDroid-9.10-arm64_bgN-Unofficial.img.xz A13 firmware. The firmware does not start. Although if you install it according to the instructions, there are no problems. I'll try on earlier versions. So far I have a proven option - this is an image of the stock pac firmware with the super partition re-partitioned to 5GB, encryption disabled, twrp and a patched boot. And modified mod_super_gsi_5gb.

You will need an unlocked bootloader. Then we flash the stock mod, go into the firmware and enable debugging and reboot into twrp. In twrp we install mod_super_gsi_5gb in the super section. We do a full wipe and reboot again into twrp. Install the gsi firmware in the system partition and reboot into the system. I tried to install gsi Elexir and Derpfest based on A14 - the firmware did not start. Only crdroid a14 starts, but it has bugs. Sometimes it freezes or reboots.
[Device Reviews and Information] AllexBast:
I'll try to change the stock firmware so that I don't have to use mod gsi super.
[Device Reviews and Information] AllexBast:
Only for the IPlay40 (t1020s) model

It turned out to make a modified firmware based on the stock. Now you just need to unlock the bootloader. Flash this firmware. Enable USB debugging. Reboot into twrp and flash gsi firmware to the system partition. Then do a full wipe and reboot into the system.

can you suggest root, rom method?
[Device Reviews and Information] eddi11simao:
Is there any possible bluetooth fixes in sight? (Like those options for Mediatek devices and such, or possibly a magisk module of sorts), or we would have to hope the gsi mantainers would stumble with this problem and fix it themselves? Thank you very much for all your work, had great success with a variety of GSI roms, but unfortunately had to revert to stock because I use headphones with my tablet a lot. Thank you again!

I just installed the latest (v20240401) SuperiorOS from here:

AOSP keyboard gave me some issues but I quickly installed Swiftkeyboard through APK and now it's all good. Unfortunately Bluetooth also gives issues with this ROM, it does not work. This seems to be an issue with all ROMs i've tested so far.

For my purpose of using this tablet for some light gaming, Youtube and reading comics it's a perfect ROM. Security patched till May which is very good.

Hi, someone knows whats is the max recommended temperature of this tablet? Mine hets hot with some games like Black desert mobile.
[Device Reviews and Information] White_Spot™:
Mine suffers from high temperature shutdown´s. When it not shutdown it almost all the time at 39º / 41º degree.

Done a factory reset but nothing changed.

After a factory reset I tried to run it without apps added and I can watch youtube playback during hours that no reboot occurs. My daughter tried to install a game and it shutdown almost imediatly.

The shutdown´s can occur almost imediatly after a boot up or living iddle mode, or it can occur only after some time (several minutes / more than 10 minutes) playing.

I read somewhere that openning the tablet and putting some thermal "strip / pad" covering the cpu the problem was solved. I will try this solution as was not interested to send back the tablet to China. The store give me 75€ of refund and the tablet cost +/- 175€.

First I think I will try to flash the original rom (without the updates) because It can be related to some software problem. The first time I booted the tablet it ask to be updated (more than one I think) so I never used it without updates.
[Device Reviews and Information] Cartmannnn:
Thank you for the info. Im interested in your case, write your results if you do the pads thing or the flash.

PS: In the web of alldocube there are the firmwares and the program to flash it, i personally couldnt do it with that version of the program, tried with another older version found in the official web of the creator and worked.

The last update is bad i have mine in the next older version.
[Device Reviews and Information] White_Spot™:
Thanks, Ill inform the result as soon as done.

I´m not at home right now, but later (if my daughter as not take the tablet with here) I will see the version of the rom I have and try to search the original one in the Internet. I saw it somewhere but I dont remember where right now.

If changing the rom dont solve the problem I will try the thermal approach.
[Device Reviews and Information] White_Spot™:
So the ROM version of the tablet was T1020S_V1.0_20210525-1707. Tried install the first ROM version (iPlay40(T1020S)-EN-20210121) via the update app of the tablet and it give an error on reboot and stay at the same version.

Tried to install via the software downloaded from the Alldocube website and I couldn't do it to.

I downloaded from the SPD website the last version of the tool (SPD_Upgrade_Tool_R25.20.3901) that was "older" than the one from Alldocube website (R26.21.2801), and in the second attempt I managed to downgrade the tablet.

I installed the app One Booster to "see" the temperature of the tablet and installed a game my daughter play (Toca World or something like this).

First impression no temperature warning and no shutdown but it means nothing as before the downgrade my daughter can use sometimes the tablet without problems.

Now is gone to her grandparents house and I have to wait her to tell me if the problem persist or no.

When I receive her information (late today or tomorrow) I inform.

I hope that is a "software / ROM" problem and nothing else as is strange all the reviews tell is the best tablet price / performance and none have suffer from temperature shutdown in few seconds of use as I do.
[Device Reviews and Information] Cartmannnn:
Ok, thanks for the info. Ill stay tuned to your reply.

hi!

I'm having problems unlocking the bootloader.

On cmd, following through with the command fastboot flashing unlock gives me this response:

FAILED (remote: 'Not implemet.')

fastboot: error: Command failed

Any ideas? Was trying to find solutions googling around, but after an hour or so I'm quite hopeless
[Device Reviews and Information] White_Spot™:
I call my daughter yesterday at evening and it says that the tablet have at least one shutdown.

So it seems that the rollback / downgrade of the ROM dont have the expected result. In the next days will see if the situation remains or not.
[Device Reviews and Information] Cartmannnn:
Do you want to flash it?
[Device Reviews and Information] Cotenartu:
Yeah, my idea is to flash magisk in order to root it as people did with iplay30.

If there are other ways to achieve root status with the iplay 40 I'll be more than happy to listen :D
[Device Reviews and Information] Cartmannnn:
I just know the official way to flash it and install stock roms, which is with research download flash tool.

In the alldocube web there is a tutorial of how to do it, but just dont use it that version of the program.

Mine gets 43° Celsius playing some games and i think its too hot i know this through Aida 64 app.

Any new info?
[Device Reviews and Information] White_Spot™:
So yesterday my daughter give me the tablet and says that he believe that putting some pressure in the back of the tablet make the tablet to not shut down, or at least shutdown less. It´s a kid with 10 years old so... not very reliable in this kind of stuff hehe.

I think that tomorow I can have some time to open the tablet and post some photos here.
[Device Reviews and Information] White_Spot™:
So I manage to open the tablet. It was no very easy, I have to put a sharp blade in the back and go gently trying to lift up the cover.

After a while I managed to remove the cover that was only held in place by a glue strip (don't know the correct name) as shown in the photos.

In the inside nothing special to talk about...

Before opening the tablet I tried to play freefire and after +\- 45 seconds of play the tablet shutdown. To be more precise, the tablet was completely off from yesterday and it was powered on and in 3 minute or so I start to play (not in the menu, really playing) and 45 second after it shutdown with the abnormal temperature warning.

This video is not form today but it show the error.

After remove the back cover and booting the tablet I try again to play freefire and I managed to play a complete round (+\- 16 minutes) without problems. I continued to play and no problems at all.

At touch I don't feel nothing barely hot in the "inside / back" of the tablet.

Installed some apps to watch the temps and during playtime the temperature was between 45 and 47 degrees (in second photo the temp is in the middle left side).

Now after several hours in standby the tablet is at 25 degrees. But almost instantly all the cpu cores goes to 100% and are "floating" around 30% and 90%, and of course the temperature start to rise.

So two things goes in my mind... the first one and not knowing if this is normal, I think that something is not normal making all the cores of the cpu to be in high use, even doing nothing with the tablet. If somebody know a app to see what app(s) are making this cpu usage I appreciate.

The second thing came to my mind... if no heat is felt in the back of the tablet, and the cpu are beneath one of the metallic shield (I presume in the large one with no sticker, see in the photo), maybe there is no thermal paste or thermal pad in this area causing a poor (complete lack) heat transfer.

With no cover the tablet seems to manage to not shutdown because the "abnormal temperature", leaving to think that with the cover, the heat somehow don't have how to leave the inside of the tablet (dissipate) because is completely closed (or fresh air to enter). Adding to these, the lack of transferring the heat from the cpu to the metallic shield and to another large area of the tablet make everything worse.

What do you think?
[Device Reviews and Information] Cartmannnn:
I think its possible its a software problem powering up the cores and making the temperature higher, but i think like a pc when you play a game, the cores go 90%.

Anyways if without the back cover the tablet dlnt shutdown is a temperature problem. Mine gets 43° max in some games, if now yours get 47°, with the back cover put in, its possible it gets 50° or more. I asked to the alldocube seller in amazon about the temperature and he says me the tablets can work to 50°. Its possible than if it gets more than 50, the tablet shutts down. In conclusion your real problem its the temperature i think. The cpu is in one corner, and it is which gets hotter, its possible that a thermal pad put on the cpu can help it.

PS: The glue of the back cover still works after open it? Or how do you reassemble it?
[Device Reviews and Information] Cartmannnn:
What its the name of the programs in the photos?
[Device Reviews and Information] White_Spot™:
The problem is the tablet at idle and not at gaming. At idle have almost all the core at 90%/100% seem strange to me. If the cores are always at full work is normal that they will produce more heat...

I searched online and allegedly the normal temperature of an android phone / tablet is between (+/-) 39º and 45º. At gaming it can go up to 68º or more and its not alarming because before anything goes wrong with the cpu it will shutdown or throttle.

So, my daughter took the tablet yesterday at the end of the day and today I will see what he tells me. The tablet is without the back cover but in a protective case (specific for this tablet) so the airflow is lower but better than with the back cover.

The cpu is not at one corner, is really think is beneath the metallic shield I said, and like I say nothing is hot at touch so I think that a thermal pad will does nothing.

No the glue (its a strip / tape) can be reused, but I think I have some similar tape. If the tape I have doens´t work I will use any kind of glue... maybe hotglue hehe.

i'm interested into making custom roms for the tablet, i was able to unlock its bootloader, but seems like when i try to flash a partition such as recovery it just hangs
[Device Reviews and Information] Cartmannnn:
I only notice the one corner near the volume buttons gets hotter when i play games, only that corner, all the other parts not gets hot never, due to that i thought that was the cpu, if not i dont know what is in that corner.
[Device Reviews and Information] White_Spot™:
Using my previous photo...

... and this one...

... the cpu is beneath the metallic shield as I said. The hot area you say (bottom left on the second image) are maybe from the little metallic shield but I don't know what is under it.

Today my daughter was with me (I´m divorced) and he tell me that using the tablet with the protective case / cover it will shut down also. I run the freefire game and in few instant’s the tablet shutdown. It rapidly remove it from the case / cover and the only "hot" part was the big metallic shield (with no sticker). Attention, by hot It only means that I can feel something hotter than the rest, is not even hot to hurt at touch or something like this.

The app I use to see the CPU usage is CPU Monitor.

And this is a "log" of the CPU usage during the night:

It’s possible that the app don’t give correct measurement, so I installed it in my Redmi 5 and the CPU usage at idle was normal. Almost all the time at +/- 30% with spikes at +/- 100%. The tablet is the opposite, almost all the time at (or higher) +/- 90% with spikes at +/- 30%:

After googling a lot, I’m almost certain that the behaviour of the tablet is not normal. The strange thing is even with almost full use of the CPU no lagging is noticeable.

I read somewhere that a similar problem was due to a TTS app problem. Later at home I will test it.

If possible Cartmannnn install the CPU Monitor app and see how the CPU usage is.

The other "stupid" test I will do is make a factory reset and put the tablet in English language and not in Portuguese during installation. After that, install from apk the CPU Monitor APP to be sure no other app was causing this behaviour and if no change is noticed I will have to install a CPU watchdog to see what app is causing this.

For me, the constant full load of the CPU is the principal factor of this problem.
[Device Reviews and Information] White_Spot™:
Do you have managed to unlock the bootloader? I'm trying to and I cant get communication with the tablet in fastboot mode. In normal use the tablet is recognised but in fast boot not, in device manager the tablet show as unisoc phone with orange warning sign.
[Device Reviews and Information] White_Spot™:
I managed to communicate with the tablet in fastboot mode (not in fastbootd) but the command for unlocking (fastboot flashing unlock or fastboot oem unlock) don't work. But if I try the lock command (fastboot flashing lock) it works and show in the screen.

Fastboot mode with confirmation of bootloader locked (fastboot flashing lock). Command send twice to see if it change to unlock state. Sorry for the poor photo.

Fastbootd mode. No communication with computer in this mode.

In fastboot mode I can send the command fastboot devices and the tablet is identified, but almost all other fastboot commands I tried give an error like remote 'not implement.' (or something like this).

Any solution?

[Device Reviews and Information] 17721:
I recently got an Alldocube iPlay 40. The tablet is awesome for it's price, but I faced an issue that keeps nagging me and I can't find a solution how to resolve it.

I tried every available combination of different settings, but the the tablet keeps shutting down my USB GPS-dongle. The problem isn’t in the dongle itself, because if I plug it into a couple different android smartphones it works flawlessly (the blue indicator light of the usb-gps is always on). Even if I uninstall from a smartphone a specific app (I use UsbGps4Droid) that's needed for data exchange, the dongle will work fine with turned off display. So, that means it’s the problem with Android 10 system of iPlay 40.

Now, I will list down below some settings available for tweaking:

The first one is the 'Power Saving Optimization' with 3 options available (Settings -> Battery -> Power Saving Optimization -> Choose battery saver): Smart saving / Power Saving / Ultra Saving. The 1st one should be for normal use, considering that you can’t turn off 'Power Saving Optimization' and you're forced to choose between the 3 options.

The next one is 'Battery Manager' (Settings -> Battery -> Battery Manager) and it’s off.

'App standby optimizer' is also off (Settings -> Battery -> App standby optimizer -> UsbGps app): close app optimized (off) / no optimize / no optimize / no optimize. UsbGps app has all permissions (long tap -> app info -> permissions). But as I mentioned above, the app permissions are not related to the problem, because I can uninstall it from a smartphone and the dongle will work fine without shutting down.

So, that’s about it. My tablet is rooted, so I’m free to change anything. If you have any idea how it can be fixed, please let me know. I would really appreciate your help! 👍 I recorded a video to show you:

00:00 – 01:30 – demonstration of settings;

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.

Thanks AllexBast I managed to unlock the bootloader, to flash TWRP and Magisk. The tablet is now fully rooted.

The part I don't "fully" understand is the ModSuper for gsi and the rest bellow.

This is for flashing another OS? I do this in TWRP right?

A correct image for example is lineage-17.1-20210808-UNOFFICIAL-treble_arm64_bvS.img.xz or even lineage-18.1-20210808-UNOFFICIAL-treble_arm64_bvS-vndklite.img.xz?

I have used an app that tell me that the tablet can use a AB and even a VNDK image, so I think they are the correct ones.
