I found another bug with the Tab P11 Pro/Xiaoxin Pad Pro that may be of interest. Using Productivity Mode with a third party launcher seems to break the Recent Apps functionality with third party launchers.

Steps to reproduce:

Install a third party launcher (I’ve tested Nova & Lean Launcher)

Set it as the default launcher

Turn on Productivity Mode

Use the toolbar buttons and resize some app windows (may not be required)

Turn off Productivity Mode

Open an app/apps and try using Recent Apps

I’ve tried restarting the tablet, reinstalling Nova, clearing the default launcher’s cache/storage. I’ve had to revert to the default launcher for now (Smart Launcher).

How to Fix the "Device is not Certified by Google" Error

Are you having trouble with signing in to your Google account? Can't access the Google Play Store or use Google apps like Gmail, Maps, Play Music, or Photos? Seeing a "device is not certified by Google" error? Here's how to fix that.

Let us know if it works. I will receive a tab p11 pro soon.

Here is another link about how to install international firmware with QFIL:

前言与联想的朋友聊了几句，对方答应送我一部新出的小新 Pad Pro体验一下，当然体验是有代价的，总得表示表示对不？于是就有了这篇文章——的前身。写完评测的开头我就觉得无聊了，这明明只是一个主打性价比、屏幕不错的平板，并不值得大书特书，除此以外还有什么好夸的呢？思来想去我又问了问有没有操作空间，答复是：有，刷国际版系统，对于Google生态用户而言比国内的预装ZUI好用多了。于是这就有了下面内容，当然在开始教程前，简单介绍这部平板。个人主观体验我用来看完了Netflix的新剧Queen\'s Gambit...

[Device Reviews and Information] MattySAu:
Thanks for that

I should probably have mentioned that I did enter my devices GSF Device-ID at https://www.google.com/android/uncertified/ to see what affect that might have. It doesn’t appear to have had any affect; Netflix still has to be sideloaded.

My experience was not the same as per the article. I never received a “device is not certified by Google” warning prior to completing the GSF Device-ID registration. So, perhaps Google have changed the way this is handled – perhaps the warnings don’t appear immediately after you login to your Google account anymore?

Or, perhaps Google has different categories within the “Device Not Certified” designation. I don’t believe that this situation is what play protect certification is really about – the Xiaoxin Pad Pro tablet has identical hardware and (with the ROW ROM installed) identical software to the certified Lenovo Tab P11 Pro. The device is not rooted nor is the bootloader unlocked. Perhaps there is more leeway because of this, or, for large manufactures in general.

I’m not certain as to the exact reason why a TB-J706F_PRC is not certified, given that the Chinese/ZUI ROM *I think* now supports GSM. I’m guessing it’s because Lenovo didn’t submit the TB-J706F_PRC with the ROW firmware for certification – for legal, political or just cost saving reasons?

These tablets are very interesting, thanks for the review. I wanted to ask you please could you extract the system apk from these tablets (clock, calendar, calculator ...) and upload them here or on apk mirror? On apk mirror the zui apks are old. Then I wanted to ask you one more thing, are these system apps the same in both the "zui" and "international" versions? Or in the international version have they been replaced by the google counterpart? Example zui clock and google clock
[Device Reviews and Information] Tamlyn:
As someone who is following this thread with interest, could you let me know if the sideloaded Netflix still let's you watch stuff in HD?

I'd be very interested in what it shows under App Settings -> playback specification for your device!

Thanks for your input into the thread - great to understand the options here

It seems like a lack of Play Protect certification (failing a ctsProfileMatch check) doesn’t affect Widevine/Netflix DRM. I guess there is no guarantee that this will continue to be the case.

From my understanding, any developer can use the SafetyNet Attestation API to:

Hide their app/not allow it to be installed via the Google Play store (this is what Netflix does), AND/OR

Allow their app to run but block certain functions (such as with Google Pay - you can’t run contactless setup)

Block the app from running at all (I think some banking apps do this, but not the ones I use, fortunately)

I’m not really sure why the TB-J706F_PRC fails a ctsProfileMatch check though. I presume it’s because Lenovo didn’t/couldn’t submit the TB-J706F_PRC variant (the Xiaoxin Pad Pro) for verification.

Reading some Chinese/Taiwanese forums (via Google Translate) it seems like the Xiaoxin Pad Pro’s firmware (the original Chinese ROM with ZUI) didn’t support GMS (Google Mobile Services), but an OTA update has since provided support. I guess supporting GMS does not include passing Play Protect certification though.

The other possibility is that just flashing a different ROM is the cause (even when using Lenovo’s official software to flash their official TB-J706F firmware).
[Device Reviews and Information] Tamlyn:
Thanks for that @Mattysa - really informative answer.

Given me lots to think about :-)
[Device Reviews and Information] Dr.Schall:
Can you explain what exactly you mean ? Because when i just think about the term "crushed black" it seems like this is something which i experience on several display types, depending on the compression algorithm for the video clip, when nearly black areas in the video are displayed in some greyish artifact style...I saw it also on the P11 pro but only rarely and on specific source material where my other OLED panels have similar issues displaying it correctly...
[Device Reviews and Information] someguyinindia:
"The term “black crush” refers to a certain condition where a display panel outputs inconsistent colors and severely pixelated blocks while rendering blacks on the screen"....hope this explains. In my case it only occurs in dark background and brightness is low if I increase the brightness to 100, it generally goes away.
[Device Reviews and Information] zerosignull:
From what I could tell from their support matrix most tabs get one major upgrade and the P11 pro is getting updates until late 2022. The p11 is getting updates till 2023

Edit: it's 2023 and 2024 for the updates

The Snapdragon 662 platform specification states that the maximum display resolution is 1080 x 2520 https://www.qualcomm.com/products/snapdragon-662-mobile-platform, but the Tab P11 specification says that it is 1200 x 2000. How can it be 1200 ?

[Device Reviews and Information] sansei:
I just got my xiaoxin pad pro. Netflix was preinstalled, but upon launch complained that it needs to be updated. Update via Google Play didn't work obviously as store said that the device is no longer supported by this application. I had various cheap chineese tablets and never seen such problem.

What's wrong with this tablet? Does it contain some spyware that it doesn't have Play Protect certificate? Is there any chance this will ever be resolved by Lenovo?
[Device Reviews and Information] zerosignull:
When flashed with the global rom the tab is not Google play certified and some apps won't install from the playtore. But you can just sideload the app.

edit: Finally got it to work. Limizin's settings and using specifically TB-J606F_S120025_210107. Thereafter I was able to flash the latest 210420 fw. There's 6 hours of my life I will never get back. As a side note, the screen protector included with the official case is rubbish. 🙃

Hey guys - I recently bought a P11 (non pro) from Banggood. Based on what the comments on Banggood and posts here said, I wanted to flash a newer firmware on it because the older fw it was on was not finding any OTA updates. (It came with the 201105_ROW fw).

I tried QFIL and the Lenovo Assistant.

QFIL hangs/doesn't proceed after clicking download - it gets stuck at "2021-05-23 10:07:26.622 ***** Working Folder:C:\Users\****\AppData\Roaming\Qualcomm\QFIL\COMPORT_12"

on the log. I left it for an hour thinking it might do something , but it doesn't. It also gives an error "Could not find the meta_cli.exe in the Meta build" after loading the xml.

I tried @Limizin's settings in the config window as well without luck.

It is detecting the Qualcomm device on COM port correctly though.

Lenovo assistant gives a big red fail button on trying to rescue the device.

I'm using windows 10 if that makes a difference.

Anyone have any ideas? Otherwise I'm stuck with a brick =/

edit: It does still boot into the original firmware. Guess all the attemted flashing actually did nothing.

I would still like to update it though, so any help would be appreciated! :D

[Device Reviews and Information] Dr.Schall:
Well, its a more or less completely different Pad and also relatively new and so far only on the Chinese market...today was the first day I got info on this tablet, there was no info during last months for this. Maybe that's why nobody is talking about it so far...

Is there anyway to "force" the OTA? I saw May 30th update is out on the firmware mirror page, but mine still says no update available on the tablet.

(flashing it with QFIL will wipe the tablet right?)

Also, XiaoXin Pad Plus was announced/released! SD 750G! I'm having slight regret of getting the P11 and then essentially a week later this is released. (Although shipping only in mid June). Kinda itching to buy this one when it goes on sale and sell the P11...

I have the XiaoXin Pad Pro and 2 days after i bought it, i flashed the ''TB-J706F_S240073_201229_ROW'' from the mirror site above. I did this because i had a much older version. The thing is, i don't remember how i did it!!! Then i unlocked the bootloader, flashed the unofficial twrp 3.4.2 and rooted with magisk successfully. Everything was fine, untill a few days ago i started receiving system notifications about the newest official rom ''TB-J706F_S242001_210430_ROW'' which update is only 144mb and of course fails every time. I then went to the mirror site and downloaded the full raw rom to flash it with qfil. I unistalled magisk, i even did a factory reset, but the flash fails every time! Even the LMSA method fails too!!

I don't understand what is the problem! Any help is apreciated.

UPDATE

Never mind, just did it and the post by

Can you get it to boot into fast boot by removing the usb cable, then power up the device holding the volume up. The tablet will buzz but the screen will stay black. Reconnect the usb cable and the qualcom drivers should pick up the device.

[Device Reviews and Information] flotux:
Hi,

I've bought the Lenovo P11 Pro as "Lenovo Xiaoxin Pro" from Banggood (hardware model: TB-J706F).

It uses the global ROM that can be update OTA.

When I started the configuration and installation of my apps the hardware keyboard was attached via the pogo pins. During installation of several firmware updates up to version TB-J706F_RF01_210601 I used the tablet without the keyboard. After several reboots I wanted to make a final test and attached the keyboard back via the pogo pins. But suddenly I had a reboot and Android was in boot loop: the Lenovo logo showed up, rebooted showed up again. And finally the recovery prompt was show as you can see in the following screenshot:

The problem can be reproduced as often as I like. It occurrs when the tablet is running but also if it is shut down and I attach the keyboard and switch it on.

The strange things are:

With the initial firmware there was no problem with the keyboard.

Even when I'm at the recovery prompt I can use the hardware keys of the keyboard to switch between the options.

When I do not attach the keyboard I can use the tablet without any issues.

I made a screen recording how it looks like when I attach the keyboard:

I already did a factory data reset but the error still occurrs.

Any idea what could be the problem or better how to solve it?

Kind regards

Florian

Make sure you are using the right, older, version of GFIL and turn off the tablet then start it up holding the volume button. Do not have the usb cable attached untill you have done this. Then use QFIL to flash the ROM.

@flotux : if you want to try, see can we get new firmware via LASM? Then we can use QFIL to flash with that firmware.

@trunglocke: I keep my fingers crossed that you manage to get your tablet up and running again. If I hear a positive sign I will try to update also to this new version.

I did a adb logcat and found some interesting information:

It seems that the German layout of the keyboard is not recognized and thus causing this error. I will provide this information also in the official Lenovo forum. Let's hope that they will fix it soon.

I am not an expert on this topic. So the most detailed explanation would be much appreciated.

I see that the link of Keshon is just linking to sets of files. I guess each is a firmware.
