How To Guide Install Stock ROM - Xiaoxin Pad Pro 2021 [TB-J716F]

[Cris74m]

@Cris74m How did you manage to get it to recognize it? Change driver?
Just download Google Play Store and install it manually.
BTW did buy your tablet with global ROM and wanted to go back to chinese?

The device was off I suppose, since it was booting by itself, but the screen was off, so I think after a while it powered itself off. I pressed the up button for like 30 secs and than while keeping it I plugged it to the laptop and magic, the laptop recognized it as QDLoader. I tried several times before but it didn't work, dunno what changed this time.
Yes I am installing google manually.
Yes, I bought it from Banggood and they took the liberty to unlock the bootloader and install a custom ROM, but I wanted the original one (since the ”global" didn't have updates and some features)

 

[Cris74m]

Now everything works fine, it even got an update to version 12.6.238. The problem is that now when I check for an update it just keep saying that it's checking, and if I go back and open it again it says that the device is rooted, but I didn't do anything apart from installing the firmware

 

[Tropaion]

@Cris74m Yeah, because with unlocked bootloader lenovo doesn't provide all updates.
In the chinese lenovo forum I read an suggestion but I don't know if it works, didn't try it but according to them it should be possible in some way.
Maybe you could try:
1. Lock Bootloader
2. Flash again with QFIL
3. Factory Reset
I can't guarantee anything, didn't have time to try more until now and currently I'm trying to get kernel source from lenovo.

 

[Cris74m]

Thank you for the advice, but right now I don't want to try again since I almost died of fear thinking that I had bricked it .
I'll wait till someone tries it before me.

 

[Tropaion]

@Cris74m I can understand that .
I will probably try it next month if I don't have success in getting the kernel source. I'm still hoping for a custom rom.

 

[Cris74m]

Yeah, I wanted to try custom ROM too but didn't find any :/

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​

• I downloaded platform-tools_r31.0.3 (https://developer.android.com/studio/releases/platform-tools)
• I unzipped it into Disk C. Example: “C:\platform-tools”
• I started CMD in the folder
• Again I turned off the tablet, started fastboot (low volume button & Power On/Off together for ~30s) and connected to PC.
• I downloaded Drive ADB (https://developer.android.com/studio/run/win-usb?hl=pt-br)
• I went to Device Manager and updated the drive (https://androidmtk.com/install-google-adb-driver-manually)
• I went back to CMD, and typed in the following commands:
  • fastboot devices (To check if the Lenovo Tablet really was there)
  • fastboot flashing lock (To lock Bootloader)
• Then the tablet asked me to confirm if I was sure I wanted to lock the bootloader (Just use the volume button to navigate and Power On/Off to confirm)
• That's it. Bootloader locked!!

- 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

This driver issue is VERY IMPORTANT, don't forget to install.

Locking Bootloader Again

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.

I couldn't install Netflix from the Google Play Store, I don't know why.

Pro pessoal que busca ajuda em Português:

Oi pessoal, vou deixar minha contribuição aqui. Fui forçado a reinstalar a ROM pois tive a brilhante ideia de bloquear o Bootloader com a ROM 'Global' instalada. Deu tudo errado e meu tablet não iniciou mais, só ficava na tela do Fastboot. Depois de ter entrado em pânico, encontrei o tutorial do “Tropaion” que me ajudou bastante.

Eu estava usando o Windows 11, e ele não reconhecia de jeito nenhum o tablet e quando reconhecia dava um erro na hora do “download content” no QFIL, o erro do “sahara fail”. Pelo menos no meu caso, tive que fazer os procedimentos pelo Windows 10 recém instalado na máquina.

Bora começar

• Usei o QFIL que vem junto com QPST_2.7.496. O instalador dos drivers da Qualcomm veio junto também. (https://developer.android.com/studio/releases/platform-tools)
• Após a instalação do QPST coloquei a pasta da ROM dentro da pasta bin. Exemplo: “C:\Program Files (x86)\Qualcomm\QPST\bin\TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.211_ST_210730_qps”
• Iniciei o QFIL e configurei de acordo com que o “Tropaion” ensinou.

O Tal do EDL

• Como meu tablet já estava preso na tela do Fastboot, então desliguei ele e pressionei o botão de volume cima, conectei o cabo no PC e no tablet, esperei alguns segundos e soltei o botão.
• Logo ele entrou no modo EDL (Ele fica com a tela desligada, mas conectado no PC) e continuei o procedimento no QFIL. (Caso dê algum erro e você queira sair desse modo é só pressionar o botão volume cima & Power On/Off juntos por uns ~30s, mas se tudo der certo você não vai precisar)
• Então ele fez a instalação e o Lenovo Xiaoxin Pad Pro 2021 funcionou perfeitamente. Porém com o bootloader desbloqueado.

Bloqueando novamente o Bootloader, agora com a ROM certa instalada.

• Baixei o platform-tools_r31.0.3 (https://developer.android.com/studio/releases/platform-tools)
• Descompactei dentro do Disco C. Exemplo: “C:\platform-tools”
• Iniciei o CMD na pasta
• Novamente desliguei o tablet, iniciei o fastboot (botão volume baixo & Power On/Off juntos por uns ~30s) e conectei no PC.
• Baixei o Drive ADB (https://developer.android.com/studio/run/win-usb?hl=pt-br)
• Fui lá no Gerenciador de Dispositivos e atualizei o drive (https://androidmtk.com/install-google-adb-driver-manually)
• Voltei pro CMD, e digitei os seguintes comandos:
  • fastboot devices (Para verificar se realmente o Tablet Lenovo estava lá)
  • fastboot flashing lock (Para bloquear o Bootloader)
• Em seguida o tablet pediu pra confirmar se eu tinha certeza de que queria bloquear o bootloader (É só usar o botao de volume para navegar e Power On/Off para confirmar)
• Pronto. Bootloader bloqueado.

Quando liguei o Xiaoxin Pad ele já tinha uma atualização da Lenovo. E foi atualizado com sucesso!

Instalei a Play Store pela loja da lenovo , e inclusive o tablet está com o Certificado do Play Protect ativado e Widevine L1 tudo ok.

[Atualização]: Netflix e Disney+ ja estao disponiveis pela Google Play pra download!!

Importante: Esse método funcionou comigo, porém não quer dizer que com você vai funcionar. Podem acontecer imprevistos durante o procedimento. Como nunca instalei uma ROM na minha vida, demorei bastante pra conseguir reparar meu erro e fazer meu Tablet voltar a funcionar . Então faça por sua conta e risco.

As imagens vocês podem conferir no meu comentário em inglês.

Espero que eu tenha ajudado!!

@PHRS thanks for your contribution. How many updates did you get? Because there is one you get even when the bootloader is unlocked (security update) and two or three after which you only get with Stock config.

I installed ZUI 12.6.211 version and it received the update to ZUI 12.6.238. I don't know what the latest version made available by Lenovo. But I hope the tablet keeps updating.

 

[Tropaion]

@PHRS ZUI 12.6.238 is the update you get when the bootloader was unlocked.
If fully updating works, you should at least receive three updates, so it propably won't keep updating.
If you open the updater now an wait for the check it will tell you that you won't get updates because of root.

I have now entered the updates and there is no message, no error message.

Hello everyone, recently I bought a lenovo xiaoxin pad pro 2021 from banggood. On DRM info app on the build info it says TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.5.126_ST_210527. Is it the original ROM or this crap-global ROM? It has no system update selection in the settings menu
Which ROM should I install so I can have the system update menu and can you tell me the process to do it? Is the one that tropaion explains in page one?

[Tropaion]

@sabaku_chris "CN" normally stands for Chinese ROM, but I don't know the naming of global ROM because I have never seen it. If the only available language is Chinese and English then its Chinese ROM.
@fazioso PHRS already wrote a bit about his expierence here, but it's not that difficult.

1. Lock Bootloader
2. Install Stock ROM (this thread)

I can't verify if updates work after it but according to @PHRS it works. I will try it myself soon too.

Thanks Tropaion.
Sorry maybe i read wrong. I believe you put in your tablet the China ROM and everything works... including update, WiFi, eccc...
Because you open a lot of threads with guides...
Understand wrong? Thanks for reply

 

[Wualk]

Adding my contribution here - I got my P11 2021 tablet from Giztop, and after two updates it is running 12.6.238 ST, just as mentioned above.

I runs the Android version TB-J716F_CN_OPEN_USER_Q00209.3_R_ZUI_12.6.238_ST_210824

This is the Chinese ROM with English translations provided (which are ok, but could use some improvements from English speakers).
