Did you only toggle the OEM options or did you unlock the bootloader with sn.img? If you only toggled it, then your bootloader isn't unlocked. You can flash the QPST like this on Windows or like this on Linux.
[Lenovo P11] asc93:
"I cannot find the sn.img file on the ZUI website, and the email did not reach me. Additionally, I did not unlock the OEM. Nevertheless, I managed to flash the original ROMs, but the device doesn't turn on, and the following message appears in the attachment."
[Lenovo P11] Ungeskriptet:
You have wait at least a day after initially connecting the tablet to the internet to get the sn.img from Lenovo.

If you have already waited a long time, you can try this guide.
[Lenovo P11] asc93:
Sure. I will wait until the end of the weekend, and if I don't receive the file, I will try this guide.

Estou no ZUI 14.127 ST, e quero comprar uma capa de teclado para usar como se fosse um PC, tem como, ou só com monitor externo?
[Lenovo P11] Kauan Timbó:
Porque eu estava lendo as respostas e várias pessoas falaram que o modo pc só funcionava com monitor externo. E eu quero comprar uma capa de teclado original, então quero saber se funciona ou não.

Can you ask your question in English? This is an English forum so please keep it this way.
[Lenovo P11] Kauan Timbó:
I'm on ZUI 14.127 ST, and I want to buy a keyboard cover to use as if it were a PC, is there any way, or just with an external monitor?
[Lenovo P11] Kauan Timbó:
Because I was reading the answers and several people said that pc mode only worked with an external monitor. And I want to buy an original keyboard cover, so I want to know if it works or not.
[Lenovo P11] Ungeskriptet:
ZUI 14 only allows PC mode on external monitors but you can use this app to circumvent the restriction
[Lenovo P11] Kauan Timbó:
How do I do this?
[Lenovo P11] Ungeskriptet:
You download and install the prerelease APK and launch it
[Lenovo P11] Kauan Timbó:
OK thank you
[Lenovo P11] kazamama:
Is ZUI 14.127 ST the latest update for the tablet? It's been months and no new updates so far.
[Lenovo P11] localbus:
that is the latest... don't think will have anymore updates... is pretty old device.
[Lenovo P11] carlosfla21:
A new update came out, I'm trying with the Chinese VPN, but I still haven't been able to update if someone can and can post the file here.
[Lenovo P11] Ungeskriptet:
If someone gets it, they can capture the link with adb logcat|grep mobile-ota from a computer. USB debugging has to be enabled on the tablet for this to work.

ZUI 15 - Android 13 for TB-J716F

It's not perfect as it looks like it might be a closed beta build? But some people may be able to use it as a daily driver.
[Lenovo P11] rollie006:
How to install?
[Lenovo P11] Ungeskriptet:
Read the README.md file inside the package
[Lenovo P11] kacang87:
just completed update to zui 14.0.266. everything seem okay so far. pc mode can be use again.
[Lenovo P11] kacang87:
is this official beta?
[Lenovo P11] Ungeskriptet:
No, not official. According to the developer they made it from Lenovo P12 firmware.
[Lenovo P11] Ungeskriptet:
I just got the 14.0.266 update myself. Here's the link: https://mobile-ota-cdn.lenovo.com/firmware/2023630162138297-7780.zip

Seems like this is a incremental update, so it can only be installed on top of 14.0.127.

EDIT: Here it is on archive.org: https://archive.org/details/j716f-firmware
[Lenovo P11] carlosfla21:
The update arrived here for me also via OTA. Back to pc mode, updated security patch, and the tablet is now faster.
[Lenovo P11] disconmair:
Hi, do I have to keep the bootloader locked before installing the update?
[Lenovo P11] Ungeskriptet:
I could download and install the OTA update on my tablet with unlocked bootloader. Although I had some problems when trying to install the zip manually, it kept saying it's corrupt.
[Lenovo P11] Tomasbr:
I have Same problem like you with manuály zip instal..

And Ota update have aby bug. After click on instal button tablet restart and after restart again show update on 266 ...
[Lenovo P11] Ungeskriptet:
Try wiping data in recovery. It should work after that. Make sure you have a backup before doing so.
[Lenovo P11] disconmair:
For me, I tried to install via OTA. It installed to update with no error, and asked me to reboot. However, nothing changed after the device rebooted. It still notifies me about the new update and the system is still on 14.0.127
[Lenovo P11] disconmair:
It still says the package corrupted after wiping data. And OTA update check keeps saying that I'm not online.
[Lenovo P11] kazamama:
Does this mean TB-J716F will get Android 13?
[Lenovo P11] Ungeskriptet:
Have you tried rebooting after setting it up again to get system update working? You can also try connecting to a different Wi-Fi network
[Lenovo P11] disconmair:
It said it had completed the system update, but still nothing changes after rebooting.
[Lenovo P11] Ungeskriptet:
Have you tried putting the update on a SD card and flashing it through recovery?
[Lenovo P11] mcdull:
From description, it only bring back pc mode.

And enhance pen functions
[Lenovo P11] mcdull:
That is the old description. This update size only 90MB. Nothing big
[Lenovo P11] darkassassinclone:
Is anyone experiencing different sound on this update? I swear dolby atmos isnt working properly and twitch streams sound different. I can tell no difference between dolby modes.
[Lenovo P11] kennyboda:
Hi Guys!

I was able to update with success but I have an unlocked bootloader. In the past I had a lot of problems returning my tablet from the dead after trying to lock it.

My question is, anyone tried to lock it in 14.0.266?

Thanks
[Lenovo P11] disconmair:
Oh yes, it keeps saying the package corrupted.

It doesn't matter if the size is small or big
[Lenovo P11] mkhakk:
Good morning guys, please I need help if anyone was able to recover widevine l1 I had l1 in zui 13 and after updating to zui 14.0.127 it went into L3 mode, it's been like this for a few days and when I saw the new update I thought maybe L1 would come back but not.

Can someone tell me if there is a way to have widevine l1 again, I have a blocked bootloader, and I need to know if factory reset or downgrade has worked for someone, I read that when performing a downgrade the bootloader does not block, so I would have another L3 time, so someone was able to solve and how?
[Lenovo P11] Jacruztin:
I installed the update with no problem
[Lenovo P11] MM.626:
PC Mode is back on 14.0.266 FINALLY
[Lenovo P11] MM.626:
even youtube sounds off... i think they changed the dolby equalizer

the sound is so bad rn the tablet went from home theatre experience to potato phone speaker from 2010
[Lenovo P11] kazamama:
Definitely the same for me too.

Was watching a movie just before updating the table but now after the update the sound feels off and quit bad.
[Lenovo P11] mkhakk:
hi. this version is okey?. widevine l1 its working? sound?
[Lenovo P11] MM.626:
Turning on mono audio and changing dolby to movie mode seems to make it sound a bit better but loses stereo audio...
[Lenovo P11] furiseto:
Audio got messed up with the latest official update, I'm really tempted to just update to that closed-beta ZUI 15 rom now.
[Lenovo P11] mkhakk:
Apparently Lenovo doesn't give a damn about its already sold tablets, zui 13 worked almost everything fine, only my youtube revanced didn't load microg correctly, but since it's a modified version there's no problem, now widevine l3 is disgusting, dolby sound ruined, and the Browsers crash when they feel like it.

only zui 15 beta left, but if the "stable" one is complete rubbish, the beta given the statistics promises to be complete unstable rubbish.

someone tried it??
[Lenovo P11] mkhakk:
did you get widevine l1? after downgrading
[Lenovo P11] Kwawarmah:
After OTA update to zui 14.266st my play store is unregistered, can someone help?
[Lenovo P11] furiseto:
go to Settings -> Apps Management -> click the 3 dots at top right -> turn on Google Basic Services again
[Lenovo P11] kazamama:
How do you turn on mono audio?
[Lenovo P11] mkhakk:
Well, yesterday finally ZUI 14.0.266 drove me crazy, it doesn't let me watch YouTube, it crashes. Oh, let's not forget that even when connecting my keyboard, it still doesn't hide the virtual one. I searched everywhere and couldn't find a way to fix it, and let's not forget about the sound, it became horrible. In other words, its purpose of being a tablet for multimedia consumption no longer exists, and it's not productive either. So, I unlocked and locked the bootloader, those who have done this will know that doing this automatically results in a factory reset, but no, it didn't work, it's still on WD L3, and the sound is still bad.

So, I downgraded to ZUI 13.0.430, I tried to lock the bootloader knowing that it would give me an error, but in the end, hope is the last thing to die. So, in the end, I stayed with ZUI 13.0.430 with the bootloader unlocked. I noticed that after downgrading, the WD Crypto API returned to 16, not 15 as in ZUI 14. Then I thought, if I'm going to have WD L3 anyway, then I rooted the tablet, installed YouTube reVanced with Magisk, and patched the apps that gave me the most ads with Lucky Patcher root, root firewall. What I mean is that I did what I could, the sound is great again, but for videos, unfortunately, I'll have to use piracy with Blu-ray rip.

To anyone reading this, if you still have time, don't go for ZUI 14, it's garbage, wait for ZUI 15 and comments.Or even better, never update.
[Lenovo P11] Kwawarmah:
It works but not registered as in bootloader unlocked.
[Lenovo P11] localbus:
hmm... you are right... the audio sounds weird... the quality is bad... but it is way louder than before 266.
[Lenovo P11] fazioso:
Can anybody write his impression about zui 15 beta? Is it good or too many bugs?

We understand that zui 14 266 update is really bugged but we like to know about beta zui 15.....

Many thanks
[Lenovo P11] CptanPanic:
I just got 14.0.266 and notice the screen brightness doesn't get dark enough anymore. The auto brightness used to get too low before in complete darkness, but now not dark enough. Can't find a setting for this.
[Lenovo P11] prozack1983:
Has anyone tried the (possibly hacked together) zui 15 beta? If so, is there anything notable or is it best to stick with gsis for now?
[Lenovo P11] kauantimbo:
Can you tell if the tab p11 pro 2021 will receive ZUI 15 and when?
[Lenovo P11] kauantimbo:
Or n Will receive? Because the sound was horrible with this new update and if it doesn't receive an update I will try this other version soon
[Lenovo P11] MM.626:

[Lenovo P11] MM.626:
its been a while since the release of this tablet, have anyone come up with a solution for 90hz flashing youtube yet?
[Lenovo P11] fazioso:
wait for update fix.... official from lenovo.... the other image was an unofficial zui 15 from another tablet...so full of bugs....and a lot of crash....dont do it....
[Lenovo P11] mkhakk:
Oh my God, it took 1 year for the update to come out between each update. Waiting for Lenovo to fix the problems is almost like praying to God. Remember that this tablet is from 2021, how many years of support does Xiaoxin provide? Can anyone guarantee they won't discontinue it? The best option in the short term is to do a downgrade
[Lenovo P11] fazioso:
but in the 266 update ..... the only bug is audio or are there others?

cause if tis only for audio there is a fix around..... i will post if i found (was in the lenovo china forum)
[Lenovo P11] kazamama:
Please do post it once you find it.

The audio issue makes it really hard for me to watch movies/Tv Shows and that is 99% of what I do on the tablet.
[Lenovo P11] fazioso:
I will post the apk

3.07 MB file on MEGA

mega.nz

works for me....

with the last update dolby app is cancelled.... you can reinstall with the apk and use the equalizer for move the volume up...
[Lenovo P11] kacang87:
I can confirm sound bug solved by installing this apps. works like charm.
[Lenovo P11] Link_gsk:
Would you guys post your custom settings for good audio? I installed the app and used almost the exact same levels I had previously but the tablet still sounds worse. I shouldn't have updated for sure.
[Lenovo P11] mkhakk:
Constant unexpected app closures, goodbye to Widevine L1, it only left L3, and then there's the issue with the sound.
[Lenovo P11] fazioso:
sorry to hear....

strange things is with dolby apk i fix (almost like before) the bug soung problem....

but also strange that the app crash for you, and most, with the new update you lost L1 widevine....

strange....for me its still L1 by now with new update 266.....
[Lenovo P11] laonglaan100:
Hi, would you also happen to have the APK for P11 Pro J706F? This tablet also got the 266 update, and ruined the audio. It's the only problem my tablet has now. :(

[Lenovo P11] localbus:
installed apk on J716F .... the sounds seems better... but the on/off button for dolby still greyed out right ?

I do not notice audio issue (tested with some audiopile youtube video). and I do not have netflix but I notice L1 security in DRM Info App. Lastly, I attached the keyboard and it run in PC mode automatically, and the virtual keyboard disappeared normally.

i need french language... i would like to stay with zui 14 but i need french language on the menu...

thanks for help

Apparently it's not using the official firmware. It has always been Chinese and English so will probably never change.

Has anybody managed to figure it out? Unfortunately I cannot go back to ZUI 13 so need to work around this. And it is super annoying indeed.
[Lenovo P11] raymerjacque:
nope, not to my knowledge... and its one of many super annoying things...

i had all kinds of weird glitches on ZUI14. screen seemed to be less responsive to touch at random times, battery would drain faster, charge slower, PC mode was screwed, then someone made a patch for it, but some features of pc mode are gone... my drop down panel was all messed up, only worked on one side of the screen, the botton dock is super f@cking anoying and you cant disable or remove it... there were other things to, but you can see, i made a wise choice to just go back to ZUI13...

You can disable it at the desktop settings

Does anyone know if the tablet will receive ZUI 15? Or is there a way to install it in a stable way, because some tablets are already receiving the update via OTA
[Lenovo P11] Kauan Timbó:
And if you're not going to receive it, you can install it because ZUI 14 isn't very good.
[Lenovo P11] fazioso:
For me zui14 is good...no audio problem and other big problems.my opinion.

For zui 15 ,lenovo start now to send beta zui 15 for certain users that subscribe to Lenovo channel.

When beta close ,zui 15 will be available for all us
[Lenovo P11] localbus:
Still in beta...
[Lenovo P11] devexa:
At least it means we will get ZUI15, which is a huuge and great news !

Multitasking was vastly improved in ZUI 15 ! We will be able to adjust floating windows aspect ratio which is not possible with ZUI14, open up to 4 apps side by side, change the default language of any app (thanks to android 13), have a decent default note app compatible with the stylus ... and more !

Why in the screenshot of other user says "snapdragon 8250" ?!?!?!

Ours is snapdragon 870.....

I think this update is not for ours j716f.... Maybe compatible but sure not official....maybe alpha version....

If someone that use this update give us feedback..... every day use.....

If not ,for now not install this update!.... We don't know where it comes.....

[Lenovo P11] TheNiceGuy11999:
I took this chance to try ZUI 14, however there were definitely a lot of issues I've encountered.

It wasn't able to root, wi-fi gets broken, and other issues that were already mentioned here. [1](The Google Account issue that was mentioned here didn't happen to me, I got it first try.) I actually got TWRP to install in ZUI 14 (credit goes to @Ungeskriptet) however it had issues mounting the system partitions. This was the same issue that happened on Android 12-based GSIs on this tablet.

Though I'm actually curious that the update moved the whole OS to Slot B instead of staying in Slot A. The boot logo also changed to Qualcomm's logo instead of the usual Lenovo logo, as well as the unlocked bootloader message not showing up after.

There were two new bootloader options too, one being booting into FFBM mode.

In conclusion, stay away from this specific ZUI 14 update for now until there is news of a more stable update.

Sean remember this is not official update...and maybe neither for our tablet but for other p11 Lenovo model..... I think is a alpha version in my opinion....stay away if you don't want troubles...or if you are real good with Android stuff....

Thanks for your advice fazioso. You just replied me in a very good moment. Because Im bein updating all zui 13 updates during this day and just now I was downloadong Zui 14 to update the tablet. But I think I will stay here in the zui 13.0.560 thanks to you.

I have bootloader unlocked. Today I updated from zui 12.0.211 ,I made 6 updates in total and Im in 13.0.560. Should I lock the bootloader now or I keep the bootloader unlocked?
