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

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 pasta 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

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.

Did you follow this guide??
Explain to me better how you performed the process and the conditions your device was in... like:
-Bootloader was unlocked?
-Which ROM was the device?
-Did you do any Updates with the Bootloader unlocked?
Try to force EDL mode (part 4. Mode1 of this guide) and redo the guide !
I made this tutorial based on 3 topics, and for me it worked well

Hi #duonglv
I faced the same problem when I was trying to lock the bootloader. The reason was that I thought the USB driver installed on step 2 was the same required on step 7 but they are not. On step 2 we need to install QUALCOMM USB driver and on step 7 it is LENOVO USB driver. After I installed the LENOVO USB driver I could get the same screen showed by #CleberJorge asking if we would like to lock the bootloader. I hope this tip works for you.

You have lock the bootloader without getting the latest ROM.

All you have to do is to follow the guides again from start. unlocked the bootloader and flash the original ROM.
After this, follow the guide above for the 7.2 Bootloader Locking Problems

Yup you’re right on the cause

I tried flashing back the original rom but it didn’t fix it

However, an hour back, I tried unlocking my bootloader with sn.img and reflashed the original rom

My device works now. Thanks!

i also have the device is corrupt issue and am only able to access fastboot. When i have tried to unlock my bootloader with sn.img it says the serial number is not matched. My serial number on the fastboot screen is different to the one on the back of the device. I also tried getting a sn.img of serial number on the fastboot screen and it is not recognised as valid on zui iunlock. Is there any fix for this or am I screwed?

Bom dia!
Eu não tenho outros links, na verdade esse link é compartilhado entre o pessoal do forum.
Faz o seguinte se for por causa do limite de download do mega:
Baixe um gerenciador de download (Jdownloader por exemplo) e espere o tempo necessario para continuar o download.

Good Morning! I don't have any other links, in fact this link is shared among the forum staff. Do the following if it is because of the mega download limit: Download a download manager (Jdownloader for example) and wait the necessary time to continue the download. bye

    Okay, your bootloader is now locked.

    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 folder 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

    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:
    https://www.mediafire.com/file/1bzfblquyofokgi/LenovoUsbDriver_v1.1.34.zip/file
    * Download this "LockUnlockBootloader" tool:
    https://www.mediafire.com/file/51352hr83iz87g5/LockUnlockBootloader.zip/file
    * Request "Bootloader" Unlock Image (sn.img) on Lenovo website:
    https://www.zui.com/iunlock

    Foto UnlockBootloader4.png


    It is necessary to inform the device's Serial Number and a valid Email to receive the file. 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 pasta 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

    2) TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.238_ST_210824
    para
    TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_13.0.346_ST_211108.zip
    https://mega.nz/file/4h13DI4R#09imnGFk0c16CPNG635AYIClewuF5rXkiaj3xqGmjA8

    3) TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_13.0.346_ST_211108
    para
    TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_13.0.364_ST_211115.zip

    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.mediafire.com/file/1bzfblquyofokgi/LenovoUsbDriver_v1.1.34.zip/file
    * Baixe esta ferramenta "LockUnlockBootloader":
    https://www.mediafire.com/file/51352hr83iz87g5/LockUnlockBootloader.zip/file
    * Solicite a Imagem de Desbloqueio do "Bootloader" (sn.img) no site da Lenovo:
    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”;
