maybe you can try right-click Lenovo Composite ADB Interface and left click Uninstall device

then disconnect your tablet, check tablet in fastboot, connect tablet to PC, check what appears in device manager
I tried it. It now only shows "Android" in other devices. Fastboot devices command can't also detect it

I am using same version as you. Lenovo 1.1.34.

If the device manager was different from the last time you tried to lock bootloader then I guess you can give it a try and lock with the batchfile
Just so you know last time i was able lock my bootloader at the latest zui 13.1.560 with no problem at all. i am only trying your method to see if will be able to lock at zui 13.1.550 like you did to see if will be able to restore my widevine to L1.

Hi, first of all thanks to all the guides and tips. I had Sahara error at first when trying to flash, but got it fixed. Now I have updated to 13.1.560 manually with all the update files, and locked the bootloader, but I'm only getting Widevine L3. Any tips on how to get Widevine L1?

Olá, em primeiro lugar obrigado a todos os guias e dicas. Eu tive um erro do Sahara no começo ao tentar fazer o flash, mas o consertei. Agora eu atualizei para 13.1.560 manualmente com todos os arquivos de atualização e bloqueei o bootloader, mas só estou recebendo Widevine L3. Alguma dica sobre como obter Widevine L1?
como você conseguiu consertar o erro no Sahara ao fazer o flash?????

Repeat these steps for each individual update

The order of updates are:
1) Stock ROM version (Chinês / Inglês)
TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.211_ST_210730_qpst

MUITO OBRIGADO AOS COLABORADORES!
This is such a nice guide, thanks!
Just today I really messed something up with my partitions and had to revert to the stock ROM using QFIL. Only issue was that QFIL was throwing errors when I tried to flash. What ended up fixing it was to enter EDL, unplug the device, set up QFIL and then plug it in just before starting the download. So maybe you could add it in your guide.
Cheers!

Oi pessoal,

Primeiro obrigado por isso funcionou para mim, mas depois que eu peguei a rom chinesa, perdi wifi 5ghz, alguém já viu isso?

Obrigado pela resposta
Meu wifi de 5ghz também parou de funcionar, já fiz rect de fábrica, mas não voltou. Mas fui na casa de um parente e o wifi de 5ghz funcionava na casa dele. O que pode ser algum problema com o nosso wifi. Mas logo quando coloquei a primeira atualização do ZUI 14, o wifi 5ghz funcionou, na segunda atualização do zui 14 não funcionou mais.

I followed instructions to flash the original rom
worked and booted
however, i missed the step on locking the bootloader after updating to 13.1.555 (i tried locking it after flashing original rom)

my device will only boot to fastboot now
flashing original rom doesn't work
it also says device state - locked

can someone guide me?

    Hello, I'm from Brazil and I installed the Chinese ROM on my p11 pro, I locked the Bootloader and my tablet got stuck on the fastmode screen, I tried to unlock the bootloader but when I run UnlockBootloader the message "oem unlock is not allowed" appears. My tablet is looping in fastmode and I can't access the system to disable "oem unlocking"

    can anybody help me?
    I´ve been in the same situation you are in.
    If you did the same as I did, You locked the Bootloader on the Wrong ZUI version..
    Then locking the Bootloader you MUST be sure you are on the ZUI 13.1.560 Version.

    There is a step-by-step instruction on unlocking the Bootloader on this entry on XDA. That is the one I use. And it worked.
    Here:
    https://forum.xda-developers.com/t/...k-file-xiaoxin-pad-pro-2021-tb-j716f.4488343/

    After that, I was still stuck on Fastboot Bootloader. Maybe because (in my despair) I tried to Install another system (without success) and ended up ruining the Boot sector (I guess that's what happened).

    To be able to reinstall the System, I had to "force" the permanent partition using the Qualqcomm app with a file I got from the system image.

    My tablet now works fine, but even after locking the Bootloader, My Widewvide is stuck on L3..
    1
    I mistyped the ZUI version (already edited the text above. To make it right).
    But Just to be sure. If you lock the Bootloader on a version different from ZUI 13.1.560, YOU WILL BRICK YOUR DEVICE.

    I know, because I did that, and it took me a while to unbrick the device.

    Help você é BR me ajuda aí, quando chega na parte do "Download Content" aparece "Get partition failes falled: MetaCli Not found" e no final "Download Fail: Sahara Fail: QSaharaServer Fail: Process Fail. Peguei o tablet hoje e já brickei , nem em Fastboot entra. Se puder ajudar agradecerei muito
    Quando deu esse problema pra mim, eu tentei abrir o QFIL como administrador direto pelo diretorio "C:\Program Files (x86)\Qualcomm\QPST\bin" , ao inves do atalho na area de trabalho, depois desconectei o cabo do tablet e conectei ele de novo segurando o botao de aumentar volume, pra mim isso resolveu esse problema

    7.2 Bootloader Locking Problems

    Only for those who are getting "Your device is corrupted" message.


    To solve this you have to manually update to the latest version ZUI 13 before locking the bootloader again.
    Follow the tutorial again with the "Original ROM" and follow these steps:

    The process for updating manually is the following:
    All updates must be installed in order from smallest to largest and all must be renamed to "update.zip"


    1) Download the update;

    2) Use a file explorer and move it to the root of your device;

    3) Rename it to "update.zip"

    4) Got to Settings => System Update => "Select the 3 dots top right and select 'Use the install package update'

    Repeat these steps for each individual update

    The order of updates are:
    1) Stock ROM version (Chinês / Inglês)
    TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.211_ST_210730_qpst

    2) TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.238_ST_210824

    https://forum.xda-developers.com/at...j716f_cn_open_user_q00209-3_r_zu-zip.5598667/

    So the version you need to be running before attempting to lock the bootloader is 13.1.555 so double check your version in Settings => My Device

    Once you have done that you will have the Bootloader locked.

    *Note this procedure works as of 25/5/22, it may change if there's a new update.

    8. Unlock the "Bootloader" (OPTIONAL)

    Bootloader unlocking is optional!
    Only unlock if you intend to install "Custom ROM" or "ROOT" the device.

    Before downgrading, make sure your current ROM is compatible!

    The following requirements must be met:

    * Enable USB Debugging "USB Debugging" and OEM Unlocking "OEM Unlocking" in developer options "Developer Options" (see step 3. of this guide);
    * Download and install Lenovo "LenovoUsbDriver" USB drivers:

The Serial Number can be obtained on the device box, on the label on the back of the device and on Android in Settings "Settings" -> My Device "My Device" -> Status "Status" -> Serial Number "Serial Number";


    8.1

    * Now you place the file directly in the “LockUnlockBootloader” program folder;
    * Start the process with the batch file “UnlockBootloader.bat”;

    7.2 Problemas de bloqueio do "BootLoader"

    Apenas para aqueles que estão recebendo a mensagem "Seu dispositivo está corrompido"


    Para resolver isso, você deve atualizar manualmente para a versão mais recente do ZUI 13 antes de bloquear o bootloader novamente.
    Siga o tutorial novamente com a "ROM Original" e siga estes passos:

    O processo de atualização manual é o seguinte:
    Todas as atualizações devem ser instaladas na ordem do menor para o maior e todas devem ser renomeadas para "update.zip"

    1) Baixe a atualização;

    2) Use um explorador de arquivos e mova-o para a raiz do seu aparelho;

    3) Renomeie para "update.zip"

    4) Acesse Configurações "Settings" => Atualização do Sistema "System Update" => "Selecione os 3 pontos no canto superior direito e escolha o arquivo"

    Repita essas etapas para cada atualização individual

    A ordem das atualizações é:

    1) ROM Original versão (Chinês / Inglês)
    TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.211_ST_210730_qpst

    https://forum.xda-developers.com/at...j716f_cn_open_user_q00209-3_r_zu-zip.5598667/

    Portanto, a versão que você precisa estar executando antes de tentar bloquear o bootloader é 13.1.555, então verifique sua versão nas configurações "Settings" => Meu Dispoditivo "My Device"

    Feito isso, você terá o Bootloader bloqueado.

    *Observe que este procedimento funciona a partir de 25/5/22, pode ser alterado se houver uma nova atualização.

    8. Desbloquear o "Bootloader" (OPCIONAL)

    O desbloqueio do Bootloader é opcional!
    Só faça o desbloqueio se você pretende instalar "Custom ROM" ou fazer "ROOT" no aparelho.
    Antes de realizar um downgrade, tenha certeza que sua ROM atual é compativel !

    Os seguintes requisitos devem ser atendidos:

    * Ative a Depuração USB "USB Debugging" e o Desbloqueio OEM "OEM Unlocking" nas opções do desenvolvedor "Developer Options" (veja o passo 3. deste guia);
    * Baixe e instale os drivers USB Lenovo"LenovoUsbDriver":

    https://www.zui.com/iunlock

    Foto UnlockBootloader4.png


    É necessário informar o Número de Série do aparelho e um Email válido para receber o arquivo. O Número de Série pode ser obtido na caixa do aparelho, na etiqueta atrás do aparelho e no Android nas Configurações "Settings" -> Meu Dispositivo "My Device" -> Status "Status" -> Número de Série "Serial Number";


    8.1

    * Agora você coloca o arquivo diretamente na pasta do programa “LockUnlockBootloader”;
    * Inicie o processo com o arquivo de lote “UnlockBootloader.bat”;

    My bootloader is currently unlocked, managed to install stock rom version 12.6.211. however I am unable to get OTA to update to 12.6.238 because system update says I have an unlocked device. I can't relock because I will get stuck in bootloader if I lock it now.

    Already had to do the HAHAHA sn edit once so I am unsure how to proceed to get to 12.6.238 from stock 12.6.211.

    Am I correct to assume that
    1. I have to use magiskhide to hide unlocked bootloader status,and then

    2. attempt OTA to 12.6.238, then

    3. manual update onwards until 13.1.555, and then

    4. try lock bootloader again?


    *EDIT*

    after switching off the tablet and turning it on a few hours later, I checked system update and was surprised to see there is option to update to 12.6.238. managed to update to 12.6.238 successfully.

    repeat steps of checking for update, waiting 5min, reboot, check Settings>My device to see if new system update available.

    managed to update to 13.1.555.

    uninstalled Qualcomm driver from my pc, put tablet into bootloader, (my device appears as Other devices>Xiaoxin Pad Pro 2021 in Device Manager) then ran LockBootloader.bat as per here

    Device booted up, automatically resetted

    downloaded DRM Info and got Widevine L1

    Thanks for instructions

    *UPDATE*
    managed to get OTA for 13.1.560. updated successfully and widevine remains at L1

    Guys,

    I bought the tablet with a global ROM and I tried to restore to the original ROM. I could restore but then I tried to lock the bootloader (to receive OTA updates) and I'm stuck at the fastboot mode.

    I tried to reflash the original ROM but when the tablet is rebooted after the reflashing it came back to the fastboot mode and it is in a loop.

    I'm desperate because it seems a bricked tablet.

    Can you help me?

    Thank you!

    Awesome compilation.
    I followed the steps and get all OTA and widevine L1.

    Thank you very much.
