Hi, new owner of SD870 version of this tablet. Thanks for the guide on getting Google Play Store working.

I have an issue with spell checker on almost all the apps. There's no Spell Checker option in the Language & Input. I'm using Gboard and have the Spell Check option turned on. But in app such as Firefox browser it doesn't show red underline for mistyped word. I somehow managed to enable it on Brave browser, it open Setting app and show a prompt asking the app (presumably Gboard) can capture all the typed words and if I will allow it. After I press allow Brave browser now have spell check. But I can't remember what I pressed that make it show the prompt and unable to have the same thing happened on Firefox. If anyone know how to enable spell check I would be very grateful.

I have tested and it works for me. The setting is under the Gboard Setting -> Text Correction -> Spelling and Grammar.

Are your tab in original Chinese ROM? if yes, maybe you want to try clean reset to factory and setup again?

Disney+ does not work for me properly. Some works and some don't (mostly Marvel titles), just blank screen but with audio and subtitles.
That is strange. I had no problem on playing any title from Disney+.
You confirm your ROM is locked Chinese original version?

So far from the initial launched version till the OTA updates, I did not face any no video problem on Disney+.

Do you mind to reset to factory default and test only with Disney+ to confirm?

Yes , it's chinese rom . But it just auto update last night . And I got the same issue with messenger . I deleted messenger . Maybe I must wait for zui15
May I know what Messenger you are referring to?

Messenger app of Facebook . I found some issue .
With old firmware, i can use messenger normally, i can call without crash. But it crashes when I use usb debugger (I turn it on to use USB tranfer and make my pad become second PC monitor ) .
With last firmware , I can't use messenger when I make a call . It will be crash and reboot. But I dont have problem with usb.
Now , I use the last firmware . I must use Facebook lite to chat with my friend . I have mipad 5 use chinese firmware, but I use messenger normaly . I think the problem come from ZUI 14 Chinese. I'm waiting for ZUI15 and I hope it better .

As far as I know there is no support. But your Kompanio 1300T version can use gl rom. You can check another topic to find it

Oh, im little stressed, last thing I want is to brick it.

My unit is 6gb ram, Kompanio 1300T version, TB132FU.

I heard the global version should be able to? Has anyone done it successfully here?

Thanks a lot guys for the advice.

I've now did a factory reset and reinstall Disney+ but no luck. Same result, no video but with audio and subtitles on most of the titles.

And yes, my ROM is the original Chinese version.

Hmmm. I've no idea what could be the root cause. From the 1st official ROM, till the most current OTA, my Disney+ had no problem to play at all.

Anyone had similar problem?

Hello everyone, does anyone know where I can download the full firmware or OTA update files for the version with SD870, so that I can extract the boot.img

    Instructions for getting root TB138FC runing ZUI 14

    Read carefully:​

    All actions below are at your own risk. I did this and above posted Magisk patched boot.img for firmware 14.0.820.​


    UNLOCKING THE BOOTLOADER:
    * This will delete all you data

    Step 1: Go to SETTINGS Menu and click multiple times on your ZUI version. This will give you Developer access.
    Step 2: Go General Settings menu > Developer options
    Step 3: Click to enable OEM unlocking, also enable debugging mode.
    Step 4: Download platform-tools_r34.0.1-windows to your computer, you may also need usb_driver_r13-windows, unpack everything in a convenient place for you
    Step 5: Go to the platform-tools folder and run the command prompt by writing CMD in the folder header and press Enter
    Step 6: Connect your USB cable and run the following command:
    adb reboot bootloader

    Step 7: Run the following command:
    fastboot flashing unlock

    On your tablet Click volume UP to unlock your bootloader
    Wait for the confirmation on the tablet screen

    Step 8: Run command:

    GETTING ROOT ACCESS:
    Put your Qualcomm device in 9008 mode
    * You may need a qualcomm usb driver for 9008 mode to work properly

    Step 1: Turn off the power, then hold Volume UP and insert the USB cable connected to the PC into the tablet
    Step 2: Use the EMMCDL_GUI tool to dump partitions boot_a and boot_b

    In the program, select the brand Lenovo, model TB-J716F and download the file 29-11-2022_19-32-13_prog_firehose_ddr.elf
    Then you need to select the physical partition number 4, select the UFS memory type, and click get GPT partition table
    In the list, select the boot_a and boot_b sections and click read from device in the context menu
    The resulting partition dumps will be located at \EMMCDL_GUI_1.5\Temp
    Disconnect the tablet from the PC, hold volume DOWN and power button for ~10 seconds until you feel the vibration

    Step 3: When the tablet boots into the system, enable USB debugging via ADB in the developer settings

    Go to the folder with platform tools and start the command line by writing CMD in the folder header

    Enter the command to determine the effective slot:
    adb shell getprop | grep slot
    If you see ro.boot.slot_suffix=_b, then the system is running on slot b. If ro.boot.slot_suffix=_a then slot a
    Install the latest version of MAGISK manager app on your tablet
    Copy the current boot_*.bin to your tablet (Instead of an * , select your version received by the grep slot command)
    Open MAGISK and click Select and patch a file. Find the boot_*.bin you copied and patch this file. Wait for the process to be completed
    Copy Magisk patched boot from the Download folder on your device to the platform-tools folder on your PC, then rename it to boot.img

    In the command line window on the computer, enter the command:
    adb reboot bootloader

    When the tablet boots into fastboot mode, enter the command:
    fastboot flash boot boot.img

    Wait for it to complete then:
    Done, your tablet is now rooted

    Awesome guide @BlackVictor , I rewrote it on Rentry to make it a little more clear and better visuals.

    Good Day !
    Are we have any chance to active google account in this tablet ? or any international ROM to solve this issue ?
    It did work with the following steps:
    1. Install Google Playstore apk (from APKMirror and look for ARM64-v8a architecture)
    2. Install Google Play Services apk (from APKMirror and look for ARM64-v8a architecture)
    3. Install Google Services Framework 12 apk (from APKMirror and look for ARM64-v8a architecture)
    4. Turn on the Google Basic Services:
      Settings -> Apps management -> 3 dots on the top right -> Google Basic Services

    The PC mode is having a workaround. Go and try it out.
