I don’t know of any way to leave widevine L1 on a unlocked rooted device, and you can’t get root on a locked bootloader. And lastly, if you lock the bootloader with magisk boot patched, the device simply will not boot
[Lenovo P11] BlackVictor:
I'm not sure if the program supports English, as a last resort, use a phone with the google translate application through the camera.

In any case, be sure to make backup copies of the files you plan to modify.

My TB138FC arrived bought on Aliexpress to Brazil, when starting I noticed that it took a while, I did the initial configuration and downloaded the update that was available, in the middle of the process the tablet turned off the screen and stayed like that for + -10 minutes, I thought that it had run out so I forced a reset by pressing the Power button + auto volume + volume down, when resetting the device it started to have problems, it kept crashing and showed an error in the operating system, I tried to restore factory default but it didn't solve it. At the moment it doesn't even turn on anymore, it stays on the home screen with the Lenovo logo and doesn't change. I searched the Forum and saw that there was a ROM posted in the first comment, but I couldn't download it, could someone give me the link to the original CN ROM to restore the system please?
[Lenovo P11] mooms:
The problem was on your end, not on 1fichier.

The 1fichier mirror is not corrupt, it's the exact same file than the one hosted on MEGA, that I've downloaded and uploaded on 1fichier.

Depending on your country, you may have better speed on one or the other.

I've downloaded them both again and compared their checksums to be sure, they are the same:

Here is the link again: https://1fichier.com/?amf62cgo1wt84hqv1j3l

For anyone who have issue to download the file, either on 1fichier or MEGA, you can use Jdownloader, it can resume the download.
[Lenovo P11] mooms:
So, I ve uploaded the file on Mirrorace, with multi mirrors:

Preciso da sua ajuda, meu tablet chegou e na primeira atualização o software foi corrompido, depois começou a engasgar e reiniciou sozinho. Restaurei o padrão de fábrica e não resolveu o problema, reiniciei e tentei reinstalar a ROM que encontrei no primeiro post do fórum mas o tablet não entra em modo boot ou não sei qual combinação usar pressione para entrar no modo, o que isso causa? que o QFIL não reconhece o dispositivo. O que eu posso fazer agora? O bootloader está bloqueado então não consigo instalar outra ROM ou restaurar a original

***Translation***

I need your help, my tablet arrived and during the first update the software was corrupted, then it started to choke and restarted by itself. I restored the factory default and it didn't solve the problem, I restarted and tried to reinstall the ROM that I found in the first forum post but the tablet doesn't go into boot mode or I don't know which combination to use and press to enter the mode, what does this cause? that QFIL does not recognize the device. What can I do now? The bootloader is locked so I can't install another ROM or restore the original one 😞

Pls help. On ZUI 15 what keys must be pressed to enter recovery mode?
[Lenovo P11] LokiCatAU:
I was happily using my tablet, stock ROM and Zui 15 for a few weeks now. Today it rebooted without prompting and got in a state where it got to the lock screen but either as soon as you interacted with it or left it for a bit, it would reboot again. It did this over and over. Eventually I did the abd method to wipe/factory reset and now it will get to the setup screen and I can sometimes make it to WIFI settings but it lock up and then will restart. The first attempt, I managed to switch language to English so every reboot attempt afterwards will show up in English but just freezes after a few seconds. Sometimes if i leave it, it will go to a black screen but get stuck so I have to hard reset it. The only thing I can think of to try now would be to request unlock and reflash but not even sure this will assist much here

OK updated, I got the sn.img from ZUI website, I am entering fastboot by sending adb reboot recovery during startup and then entering Fastboot but then

> .\fastboot flash unlock sn.img

Warning: skip copying unlock image avb footer (unlock partition size: 0, unlock image size: 5386).

Sending 'unlock' (5 KB) FAILED (remote: 'Download is not allowed on locked devices')

fastboot: error: Command failed

So it won't accept the file meant to unlock it because it is locked? :(

I am guessing I am screwed since it won't let me get to Developer options before the device decides to lock up / restart. Factory wipe doesn't prevent the eventual freeze reboot

Hello everyone!

I'd be interested in rooting the device as I want to change the layout of the physical keyboard, specifically I want to swap the CapsLock and the Ctrl keys, and the methods to do this without rooting the device don't work (If anyone has faced this problem and found a solution or knows Chinese and knows about a forum that discusses this issue I'd be really grateful for the info).

Anyways to the rooting problem I'm facing,I am using adb from Linux and the following command works fine

But the fastboot command fails

I've updated the device to the latest version (firmware ZUI 15.0.259). I have done a factory reset before trying to root the device to be sure the protection measures (fingerprint, pattern, ... ) and/or other things didn't interfere with the process. The developer options are accessible and both the OEM unlocking and USB debugging are active.

Does anyone have found something similar? Is it because I'm in the latest version? I can't flash ZUI-14 as the bootloader has not been unlocked yet.

Anyways, I hope someone can throw some light to this issue (or how to swap keys in the physical keyboard).

Thanks!

[Lenovo P11] kanios:
Hello, I bought a Lenovo Xiaoxin Pad Pro 2022 TB138FC SD 870 tablet in the CN version and updated it to ZUI 15 and I have a few questions about the TB138FC_CN_OPEN_USER_Q00024.0_S_ZUI_14.0.625_ST_220901_qpst.rar ROM:

1. After uploading, does it allow you to change the language to other than English or Chinese?

2. After uploading, will I be able to update it to ZUI 15?

3. Is there anything I should check before starting the process of flashing this ROM to avoid crashing the device?
[Lenovo P11] ZhenMing:
The original ZUI14 firmware is available in the 1st post. And you should able to OTA to ZUI15.
[Lenovo P11] ZhenMing:
If your tablet is locked BT, this firmware won't help, as it is the same. Furthermore, to flash this ZUI14 firmware will need to unlocked the BT.

It do not have other than Chinese and English. However, user had discover an app that could set it to other languages, do check few post above for it.

Hello, I have the XiaoXin Pad Pro 2023 version that is already flashed with the Global ROM. But right now, I'm trying to find ways to change the Widevine L3 to L1 to access Netflix HD.

So far, I found that I can possibly do that with Magisk but I need the stock firmware for the 2023 version. or is there any other method or suggestions/alternatives to Magisk or etc to access Netflix HD?

Can anyone help? Been trying to communicate with the seller but they aren't helpful.

Thank you!
[Lenovo P11] ZhenMing:
Good question. I'm also looking for the answer. maybe need to use
[Lenovo P11] ZhenMing:
So far, no solution found, yet.

As long as the BL is unlocked, you will only get L3.

[Lenovo P11] inhalt:
Thanks for your guide. I was a bit worried since I hadn't flashed any device for ages, but I made it trough very easily and finally left that crappy "global" rom behind 😀

Now I'm running on Android 13 (after 2 updates) with an open bootloader and I'd like to know how to get the Widevine L1 back...

Would I have to relock the bootloader? Is there any tutorial I can follow?

Also read something about rooting and using some software to get the L1 back, but seems too much hassle... Can anybody help with this? Thanks 😊
[Lenovo P11] josemartinezx:
Hello, everyone. As many others here, I purchased a TB138FC through AliExpress, and received the one with the fake global ROM. This forum helped me to switch to ZUI 14, and I definitely like the tablet more with the original Chinese ROM. I am unsure about updating to ZUI 15, because I see no real benefit for me to install it, but perhaps there are advantages in the newest version I ignore.

But I digress. I have seen here many people asking for a way to relock the bootloader. I have just relocked the bootloader of my tablet by following this guide written by a user in an official Lenovo forum regarding TBJ606F (it is a different model than ours, I know, but the steps are exactly the same). It is an easy, straightforward and relatively safe procedure. In order to do it, you need administrative privileges in a Windows PC. Also, you need to enable the developer options and the ADB debugging mode in your tablet.

RELOCKING THE BOOTLOADER WILL ERASE ALL THE CONTENTS OF YOUR TABLET. MAKE SURE TO BACKUP EVERYTHING THAT MATTERS TO YOU SOMEWHERE ELSE BEFORE PROCEEDING. DO IT NOW. REALLY. YOU HAVE BEEN WARNED.

IF YOU DECIDE TO FOLLOW THIS GUIDE IS BECAUSE YOU ARE TAKING FULL RESPONSABILITY OF THE OUTCOME. I DID IT AND I WAS SUCCESSFUL, BUT YOUR FINAL RESULT MAY BE DIFFERENT THAN MINE. DON'T BLAME ME IF ANYTHING GOES WRONG. YOU HAVE BEEN WARNED.

Now that you have a copy of all your important stuff and that understand the risks, follow these steps to relock the bootloader of your TB138FC:

1. Make sure you have installed the appropriate ADB drivers for your tablet. Connect it to the computer with the USB cable and allow in your tablet the ADB debugging connection.

2. Open a CMD prompt as administrator.

3. Type adb devices and make sure that your tablet shows up. If it doesn't, please check that your drivers are current and that there are no unrecognized devices in the Windows' device manager. If your tablet is shown in the output, you can proceed with the next step.

4. Type adb reboot bootloader. Your tablet must be now in bootloader mode.

5. Type fastboot devices and make sure that your tablet shows up. If it doesn't, please check that your drivers are current and that there are no unrecognized devices in the Windows' device manager. In my case, I had to update the drivers via Windows Update before my tablet was recognized. If your tablet is shown in the output, you can proceed with the next step.

6. Type fastboot flashing lock. Your tablet will ask if you want to lock the bootloader. Use the volume up and down keys to select "Yes" and press the power button to confirm.

7. Done. Your TB138FC will reboot and will be ready to be set up as a new bootloader-locked tablet.

Note: This procedure was successful in my device, running ZUI 14, flashed from the file in post number 1 of this thread. I don't know if it is possible to relock the bootloader of tablets in the fake global ROM. I assume it is not, but who knows for sure.

That's it, folks. Have fun. Cheers!
[Lenovo P11] ZhenMing:
Thank you for the sharing.. however, I used to guide an owner to do so before, but it failed .. It might be due to not getting the CMD in administrator mode.

Any other people owner tested this and confirm it is working? Do feedback so that I could put a link to this post in the 1st post as a guide for other owner...
[Lenovo P11] mirlo82:
Not work for me. In "fastboot devices" i have a listed device but when i try last step, fastboot flashing lock, said command error. I try also with fastboot oem lock... not worked also
[Lenovo P11] josemartinezx:
Thanks for the feedback. I have been reflecting about the factors specific to my experience that could have aligned for me in order to be successful. Here are the ones that I can think of as of this moment:

1) The system version of my tablet is 14.0.625. I did not update to any upper version (my update app keeps saying version 14.0.820 ST is available). Version 14.0.625 is the one included in post number 1 of this thread. So, perhaps downgrading to that version might help.

2) The ADB drivers and bootloader drivers of your Windows computer have to be updated through Windows Update in order for everything to work out smoothly. I was about to give up at flashing ZUI 14 because the Qualcomm flashing tool was unable to recognize properly my tablet. It was until I updated the drivers and rebooted Windows that the process finally went through. Also, when relocking the bootloader I had to do a similar procedure, because the Windows drivers in bootloader have also to be updated through Windows Update.

I will follow this thread closely to find out if anyone else succeeds, and also to write down the ideas and possibilities that lead to a general method to relock the bootloader. Hopefully more people will try to do it and we all together will figure out the right step-by-step approach to this. At this point, I'm beginning to think I was just incredibly lucky, but I'm sure there must be a way for all of us to relock the bootloader of our tablets.
[Lenovo P11] BlackVictor:
This method of unlocking the bootloader works on ZUI14, it is described in my message when getting root https://xdaforums.com/t/tb138fc-sd870-xiaoxin-pad-pro-2022-sharing-and-support.4498469/post-88476491, but on ZUI15 there is no really working way to unlock the bootloader without problems with rolling back to ZUI14
[Lenovo P11] inhalt:
Thanks for sharing. It worked for me, but not right ahead. My PC wasn't able to detect my tablet in fastboot mode, so I eventually figured out I would need to update the fastboot driver. Windows Update wouldn't provide it, so I searched the web for help and found the file attached. Worked like a charm once I updated from the device manager.

What a great tablet this is :) I have got back to Android 12 to give it a try. I have noticed there is no double tap to lock the screen like in Android 13...

Well, I hope this can help others with the same problem I had. Cheers!
[Lenovo P11] josemartinezx:
Awesome! Thanks for confirming it works, and for providing the fastboot drivers. Hopefully more people will be able to relock their bootloaders. I'm especially interested in knowing if ZUI 15 can be downgraded to ZUI 14, and if after the downgrade this method is still valid. I suppose we need to wait for more people to try it before knowing for sure.
[Lenovo P11] inhalt:
Actually I downgraded from ZUI 15 to ZUI 14 by installing the Chinese original rom again. I didn't stop to think whether it would work out 😅. Note that was with an unlocked bootloader (in case it makes a difference). I haven't tried downgrading with a locked bootloader.
[Lenovo P11] josemartinezx:
Thank you for confirming that this works in ZUI 14 after downgrading from ZUI 15. Hopefully the ones who tried before and failed because their tablets were in ZUI 15 will downgrade and try again.

Now I have a question for you and the whole community. I am still in ZUI 14 ver 14.0.625. I have never been a fan of upgrading to newer versions just because, and in my long experience using gadgets, upgrading is not always the best you can do (new firmware bugs, decreased battery life, worst performance, weird cosmetic changes, etc.)

For instance, my daily driver phone is a four-year old Huawei P30 Pro. It once updated itself to Android 11 and I hated it, so I downgraded back to Android 10. I have never felt I'm missing anything important: I can install and use every app in the Play Store (and in the F-Droid catalog), the battery management is much better and the user interface is cleaner. Perhaps it is just that I am a pretty basic phone user...

So, the question is: will I miss anything really important, or useful, if I just keep my TB138FC in version 14.0.625?
[Lenovo P11] inhalt:
I didn't notice anything wrong with ZUI 15 during 2 days. It felt very similar to ZUI 14. So far I'm only missing the double tap to lock the screen...

However, you can just try ZUI 15 and get back to ZUI 14 if you don't like it. Downgrading is as easy as flashing the original firmware just like you did to get rid of the "global" ****ty rom it came with 👍
[Lenovo P11] josemartinezx:
You are absolutely right. There is no other way to know than trying ZUI 15 out.

Regarding the double tap to lock the screen, unavailable in ZUI 14, I know it is not the same, but screen can be locked by tapping an icon in the control center (revealed when swiping down from the top of the screen). If you reorganize the icons in the control center, you can actually lock the screen with a swipe and a tap. Agan, not the same, but pretty close to the double tap.
[Lenovo P11] OttoKS:
I have the fake global rom version and just tried to flash it. But it keeps saying Download Fail. How do i get it to actually flash the firmware?

EDIT: I redid everything the same way, but on windows 10. Now it worked perfectly well!

Edit 2: I was trying on multiple Windows 11 devices.

hi

I encountered a problem with my TB138FC tablet running version 14.0.820, and I believe it has a pseudo-global ROM.

I decided to remove the pseudo-global ROM from my TB138FC.

I downloaded TB138FC_CN_OPEN_USER_Q00024.0_S_ZUI_14.0.625_ST_220901_qpst from https://mirrorace.org/m/6BuwR

I installed Qualcomm USB Driver V1.0 and QPST_2.7.496.

I turned off the tablet, pressed the Vol + button, and connected the cable. The tablet appeared in devices as something like "Qualcomm....9008 (COM5)," and QPSTConfig.exe also detected it in the Port tab (on com5). It was confusing that nothing was displayed on the tablet screen, just black as if it were turned off.

I opened QFIL, checked the necessary checkboxes in Configuration,

In QFIL selected the only available port with device com5.

I unpacked TB138FC_CN_OPEN_USER_Q00024.0_S_ZUI_14.0.625_ST_220901_qpst.rar and pointed contents.xml from there.

When I attempted to click "Download content," QFIL complained that QPST was running (I closed QPSTConfig.exe that was running at that time) and clicked "Download content" again."

Here is what QFIL wrote further (LOG in the attachment)

Actually the tablet is disconnected from the computer, the black display did not go anywhere and now when connected to the computer, there is a sound of connection and is defined as an unknown device USB Device Manager.

In fact, the black display was from the moment of clamping + and connecting the cable, I do not know if it is normal.

On the Power key also seems to not react, in any case Unknown usb device does not disappear.

Any ideas what happened to it and how to revive it or is it just a classic brick? And how to revive it then?

UPDATE: while reading the topic, I found a message from Blackvictor

"Hold "Vol -" and the Power button for about 10 seconds,

after vibration, release the buttons

-" Then hold down the "volume control button +" to load the bootloader, select "Turn off the power" in it.

Then, after turning off the device, hold down the "volume control button +" and connect the USB cable."

and the tablet started working, I did not re-enter the EDL yet

It helped, but the question is, did I really try the right steps to update the pseudo-global to put the Chinese ROM?

Offcourse ... Win 11
[Lenovo P11] Alexislol2001:
BTW, I'm having this issue...

When I charge, it start charging, then it shift to turbo-charge, the problem is: it looks like it stop charge and immediately start charging again and then turbo-charge to loop the same cycle over and over... It's a bit annoying because it vibrates every time it start charging again...

Is my tablet port broken? Is my charger? I'm using the original one 68W that looks like Motorola's one (probably the same) also happen with original cable, I bought 2 Anker cables 100W and is the same...

When I charge slowly with my Samsung A52s charger of like 15W, this doesn't happen
