Pois é, ainda não sei se a Lenovo pretende disponibilizar uma versão global... Mas usa de boa a versão em Português que vem com ele... Pra falar a verdade eu ainda nem ia atualizar pra Rom chinesa, mas fiz uma besteira então fui obrigado a atualizar kkkkkk

Mas caso tu precise do Widevine L1 e queria receber atualizações de firmware da Lenovo, tu vai precisar mudar pra Rom chinesa e travar o Bootloader. Então utiliza esse guia como referência. Eu escrevi também com detalhes minha experiência na página 2.
it's a splinter, such a powerful tablet and only having these two languages and not having custom ROM options is sad, I hope one day someone can do it 🥺🥺 I chose it because the Mi pad 5 lost in some aspects, anyway, I hope the mine come soon...

Using ADB AppControl I've disabled a few packages.
Here's the log:

So far so good, everything seems to be fine after about an hour.
Lenovo's "Security" app is pretty shady, you can disable it with adb shell pm disable-user --user 0 com.zui.safecenter
Just one quick question. Can these bloatwares be disabled with the same effect in android by going to the apps section?

Everything can be uninstalled using ADB, even vital system apps, so take great care!
Use ADB AppControl, it's a lot easier to use! (I have the Extended Version, since I thought supporting this awesome project is vital for it to become even better.)
I've uninstalled all the bloat I found unnecessary, like Lenovo's File Manager, Clock, the ZUI Home itself (since I use Nova Launcher Prime)...
Am new to this so I would have to read a lot more before doing something that I might regret later for not knowing what I do not know ...or if I do it, it will be one bloatware at a time to get the feel on how the tablet's android environment handle uninstalls through ADB.

Would you mind listing the "bloat" apps that you've disabled...
I've rooted my tab so I'm going to freeze the stuff I don't need (Like the Launcher) and a list would be useful.
thx

I disabled these already: APP Center (chinese lenovo app), HD Browser, LeCloud, LeVoice, ZUI Home (am using Nova Launcher)...Also, don't know the app on the changing of font because it is in Chinese (italics/bold/condensed?) It does not bother me disabling them but it is eating storage space.

I've attached my DeBloater Windows .cmd - everything seems to work fine here, but take great care!
BTW, I've re-enabled Security app, because it has the permission control built-in, otherwise you can't change app permissions!

Edit: if you don't want to use a third-party launcher (like Nova Launcher), comment out this line:
adb shell pm disable-user --user 0 com.zui.launcher

BTW, disabling the ZUI Launcher has the sideeffect of not being able to reach recent apps! It has too many things built-in (even nasty ones!), and it uses almost any kind of permissions, so I can live without it.

So do I need to root for this or can I use it without?

Finally managed to install China ROM. I started with unlocked bootloader and Banggood tablet with global ROM.
Everything OK, finally got Widevine L1, OTA. Only English and Chineze languages. Netfix works in FullHD.

I have run into sahara fail issue on windows 11. To resolve this, I followed @PHRS and @Tropaion guides. USB debugging has to be enabled first in the tablet menu.

1. Install Qualcomm USB Driver v1.0 and restart computer
driver.jpg


2. Install QPST Tool in default path ProgramFiles(x86) https://qpsttool.com/qpst-tool-v2-7-496
3. Extract ROM content in C:\Program Files (x86)\Qualcomm\QPST\bin\TB-J716F_CN_OPEN_USER; I guess this is important, because if I left the ROM in a Desktop folder, I got Sahara fail. May be due to windows 11 security implementation and ProgramFiles file access stuff...
4. Connect tablet in EDL mode - I did it with with adb command "adb reboot edl"
5. Check if the tablet is visible in Device manager, under Ports (COM&LPT); note the port number. Tablet screen is black.
6. Execute as Administrator "C:\Program Files (x86)\Qualcomm\QPST\bin\QFIL.exe"; the port number from step 5 should be visible in QFIL.
7. Setup QFIL / FireHose Configuration as indicated in Opening post (0-Sahara, ufs, reset after download)
8. Browse Programmer path with "C:\Program Files (x86)\Qualcomm\QPST\bin\TB-J716F_CN_OPEN_USER\prog_firehose_ddr.elf" and Content XML with "C:\Program Files (x86)\Qualcomm\QPST\bin\TB-J716F_CN_OPEN_USER\contents.xml"

9. Click download content. For me it worked fast, the log showed the processes running in a few steps. I had a USB3 connection, maybe this is why it went very fast (~20-30 seconds).
10. Tablet can be rebooted with the new ROM, but still Widevine L3
11. To lock the bootloader, first install LenovoUsbDriver_v1.1.47
12. Use @Tropaion lock batchscript https://forum.xda-developers.com/t/...n-pad-pro-2021-tb-j716f.4347321/post-85775623
13. The bootloader is locked and the tablet is reset. Widevine L1 and OTA after this.
14. A bit weird boot with all the Chineze, but embedded apps can be easily uninstalled. I installed Aptoide, then Google Play, Netflix, Swiftkey instead of the chinese one, etc.

Thank you @Tropaion, @PHRS and the rest of XDA community. All the best!

LE. By the way, when I first got the tablet I thought the wifi module is broken or something, because it connected my wifi, but with limited connection. I finally realized that the date/time was wrong (because of the empty battery I guess), and after I manually adjusted the date, internet connection was established.

That's good to hear. I am just wondering if this will be the same instruction set for the older Pro model. I have mine in global rom (android 11) but wanted the chinese rom. One possible issue is that if it is successful, I might be stucked with android 10 or are there any chinese rom (android 11) for the Pro 2020? If I am not mistaken, the only advantage on the older model's chinese rom is that it has OTA update.

Hi everyone I have the global firmware with no ota, I tried to install the original via Qfil but it gives me the "download fail/firehose fail" error..
I wondered if I can install via fastboot the TWRP recovery and then install the original firmware from there... Can it work in your opinion? Thanks everyone in advance

Hi, are you using usb 3.0 port? I got the same issue too, plug the tablet to a usb 3.0 port and make sure that it is not loose and it will flash the ROM

Yes I did it using qfil and the stock rom provided by tropaion
Hi,
I had very similar problem before. I unlocked bootloader for the first time after upgrading my device (TB-J716F, Chinese rom version) to ZUI 13.0. After that, I relocked bootloader and flashed ZUI 12.6 rom via QFIL. Then, I had the exact same error message as your photo.

[What I did for recovering from that situation]
1. Unlocked bootloader again.
2. Flashed ZUI 12.6 rom provided by tropaion via QFIL. (Do not relock bootloader yet! When I relocked bootloader on ZUI 12.6 rom, the error message came again...)
3. Upgraded device to ZUI 13.0 by using update.zip files manually because I couldn't get OTA updates with bootloader unlocked.
4. (If you want, you can relock bootloader now.)

I'm not sure this will work for your device, but I hope this helps.

    How to install Stock ROM - Xiaoxin Pad Pro 2021 [TB-J716F]

    I tried installing a GSI-ROM on this tablet, which basically worked except for three/four bugs I coulnd't solve.
    So I tried to restore the Stock ROM in the meantime and will share my experience.
    Your data will be deleted, try it at your own risk.

    Requirements:
    Installation:
    1. Boot tablet in EDL-Mode, there are two ways (in EDL-Mode screen always remains off):
      • If tablet is fully booted: use adb command "adb reboot edl"
      • If tablet is off or can't be booted: press the volume up button and hold, plug the usb cable into the tablet and PC and wait a few seconds
    2. Now this should appear in your device manager:
      device_manager.png
    3. Start the QFIL-Programm, it should detect the port with the same name.
    4. Go to "Configuration" -> "FireHose Configuration". At device type select "ufs" and tick "Reset After Download" then press ok:
      qfil_1.png
    5. Back in the main window select "Programmer Path" and browse to the ROM-Folder, select the file "prog_firehose_ddr.elf".
    6. Select "Content XML" and browse to the ROM-Folder, select the file "contents.xml"
    7. Click "Download Content" and wait, may take a few minutes
    8. After its done, this status message should a appear and the tablet should reboot.

    Done, Stock-ROM should boot now.

    Hi guys, I'll leave my contribution here. I was forced to reinstall the ROM as I had the excellent idea to lock Bootloader with the 'Global' ROM installed. Everything went wrong and my tablet didn't start anymore, it was just on the Fastboot screen. The “Tropaion” tutorial helped me a lot.

    I was using Windows 11, and it didn't recognize the tablet at all and when it did, it gave an error at the time of “download content” in QFIL, the famous error of “sahara fail”. At least in my case, I had to do the procedures for Windows 10 newly installed on the machine.

    Starting from the beginning

    • I used the QFIL that comes with QPST_2.7.496. Qualcomm's driver installer came with it as well. (https://qpsttool.com/)
    • After installing QPST I put the ROM folder inside the bin folder. Example: "C:\Program Files (x86)\Qualcomm\QPST\bin\TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.211_ST_210730_qps"
    • I started QFIL and configured it according to what “Tropaion” taught.

    The EDL Dilemma

    • As my tablet was already stuck on the Fastboot screen, so I turned it off and pressed the volume up button, connected the cable to the PC and tablet, waited a few seconds and released the button.
    • Soon it went into EDL mode (It stays with the screen off, but connected to the PC) and I continued the procedure in QFIL. (If there is any error and you want to exit this mode just press the volume up & Power On/Off button together for ~30s, but if everything works out you won't need to)
    • Then he did the installation and the Lenovo Xiaoxin Pad Pro 2021 worked perfectly. But with the bootloader unlocked.

    Locking Bootloader with Chinese ROM installed


    - When I turned on the Xiaoxin Pad it already had an update from Lenovo. And it was updated successfully!
    - I installed the Play Store through the lenovo store, and even the tablet is with the Play Protect Certificate activated and Widevine L1 everything ok.


    Important: This method worked for me, but it doesn't mean it will work for you. Unforeseen events can happen during the procedure. As I've never installed a ROM in my life, it took me quite a while to fix my error and get my Tablet back up and running :). So do it at your own risk.

    Hope this helps ;)

    It has multi-language and on the product page banggood says it comes rooted with Chinese ROM with play store installed and multi-languages.
    If it was original Chinese rom, it should have update option. Am I right?
    Modified roms have no updates.
    2
    I can only think of one thing you can try to enter edl mode, which I recently read in an chinese forum.
    1. turn off tablet
    2 open qfil software
    3. hold volume up button
    4. plug in usb cable and connect tablet with your pc while holding the button pressed
    5. let lose of volume up button
    6. wait for about 2 sec., tablet should be in edl mode. qfil software should detect the tablet.
