Hello thread author and everyone might reading my comment, I really need your help and support for my lenovo pad with the codename for SD870 is TB138FC.

Actually I really need the original Chinese fw, because my device just suddently stuck and all systems were lagging, in the end its turn off on its own.

Now, everytime I try to boot to system, it just loads on the lenovo loading screen (not showing any animation, and just stuck there).

Now even worse that it just not show anything on screen, just vibration as a response (hardbrick?)

Before, I did format factory/reset data through recovery mode. But its still occurrs the same issue (stuck loading on lenovo bootlogo).

One thing I would like to mention, is that my BL still in locked mode (I have not done any UBL)

Could anyone please help me, because this device just came 2 days ago and I wish not to send it back to China (takes time and money too).

Thank you for your kindness..
[Lenovo P11] ZhenMing:
Thank you for your dedication to write this article for us. Appreciate a lot on your work.

Could I request to load Windows 10/11 ARM image to our beloved TB138FC? 😂😂🤣🤣
[Lenovo P11] BlackVictor:
Theoretically, this is possible if you follow the instructions of Xiaomi Mi Pad 5 from the Renegade Project, but I see no reason to look in this direction. The main thing is to make a backup copy of all partitions, or wait for the full firmware image
[Lenovo P11] ataman76:
I have the same.
[Lenovo P11] BlackVictor:
Boot into bootloader mode, connect the tablet to the PC, and use platform-tools to try to enter the command:

Then try rebooting, if the command didn't work, type

Devices with an A/B partition structure are difficult to kill, how did this happen to you?
[Lenovo P11] Sparta321:
As I said, that the tablet suddenly becomes lagging and suddenly the screen freeze. I let it sit for a while but then it turned off. After that, everytime I try to boot into system, it just not display anything.

Now the device in hardbrick mode. It wont even vibrate anymore.

I also contact the store to return for warranty.
[Lenovo P11] BlackVictor:
If it is possible to return to the store, then it is better to do so, but in general any partition on the tablet can be restored using the EMMCDL_GUI program in Qualcomm 9008 mode
[Lenovo P11] Sparta321:
Yes, I did research on that method. But isn't it will require original firmware to do so? Using QFIL right?

*Anyway thankyou for replying on my case, really appreciate it
[Lenovo P11] BlackVictor:
You can ask someone to make a backup of the desired partition from the work device. And then upload it to your tablet. The main thing is to know what exactly you need

[Lenovo P11] B.G.A.A.:
Clearly understood about it.

*Just pretend it as a rumor*

Yet I recently came across some random reply, claiming that they'd swiped the ROM into crDroid and worked perfectly fine🤔; though I can't find such firmware of corresponding model under the Lenovo family on the website.

Inspite of that, I think that installing the custom, stable ROM alike crDroid for TB138FC-SD870 is feasible in the coming future, right?
[Lenovo P11] euphoriaaaa:
Hi @ZhenMing, would you mind to share your feedback on the 14.0.820 ST? What are the notable improvement and flaws in this update.

Much appreciated.
[Lenovo P11] ZhenMing:
Frankly, I didn't feel much different but possible stability and more recent security update. 🤣🤣🤣
[Lenovo P11] ZhenMing:
Good news!

The beta testing of the new firmware has begun.

The main testing is on the new PC Mode.
[Lenovo P11] Sparta321:
I wonder if they are willing to upload the full ROM package for us, or would it just incremental package just like before? Even I really need an official full ROM package when things go wrong, like in my case, I did send my device back to the Hong Kong store where I bought it. My device just won't get turned on anymore, so the last option I had to do was claim a warranty. It s*cks that I have to pay for the delivery fee. But I hope it can fix the issue.

If I encounter the same error, then I wouldn't want to buy a Lenovo tablet anymore 🤔; I will use Xiaomi again since they give more support and transparency on their ROM package (it can be accessed publicly).
[Lenovo P11] Sparta321:
Could you tell us where we can get this kind of information or any related community for ZUI updates?
[Lenovo P11] ZhenMing:
So far are not sure how the update will be. But if it is still ZUI 14, I bet it will be incremental.

But if it is ZUI 15, I'm pretty sure it will be full ROM.

Let's wait for the official and I will copy the update package file to host in cloud for you.
[Lenovo P11] ZhenMing:
I just bump into their Weibo official account time to time and saw that info. If you could read Chinese, you could go in here.
[Lenovo P11] ataman76:
After all, on the screen you can see that it is unfortunately ZUI 14
[Lenovo P11] Sparta321:
I really appreciate your informations, I hope they'll soon release the full ROM package when ZUI 15 release, so user can fix the immature software issue by their own.

I wasn't expecting that Lenovo is more less put attention about this one, which in Xiaomi brand will give better support regarding ROM package (maybe it's because from the beginning, Xiaomi focusing on their mobile products).
[Lenovo P11] ZhenMing:
Since they are already promoting ZUI 15, we might not be far from it.

However, as I red from the Chinese forum, they said that ZUI 14 feature was fixed to have no PC mode when attached the keyboard. This will not change.

Unless ZUI 15 might had include that. So, hopefully this is true where we are expecting ZUI 15 with PC mode by the tablet itself.
[Lenovo P11] ZhenMing:
I'm checking ZUI14 OTA news letter for other tablet and seems like they are enabling the PC Mode and side shortcut bar. We might expecting that for our tablet too... Let's wait for the new OTA... Soon...
[Lenovo P11] ZhenMing:
Great news!

I got my OTA today and I'm using the PC Mode with my keyboard attached on the tablet, by the tablet, to write this post.

You will get yours very soon. Or you could download the OTA file here and update yourself.
[Lenovo P11] ZhenMing:
Basic review of the latest OTA 14.0.832ST where the PC Mode work very well within the tablet itself. I enjoy it very much.

However, the side panel wasn't implemented in this update. But I could live with it.

This update is very much recommended.
[Lenovo P11] evertonmdz:
Which keyboard model?

Here updated alone, test today! Let's see if it fixes the bug of closing microsoft edge alone!
[Lenovo P11] ZhenMing:
Did it had different keyboard? I just got one which is for our tablet.
[Lenovo P11] euphoriaaaa:
Hi ZhenMing, I am currently on 14.0.625 but I am only seeing 14.0.820ST as the latest update.

Did you use the Chinese VPN to get the latest update? Or was it pushed to you automatically?
[Lenovo P11] euphoriaaaa:
Manage to update to 14.0.831 after the 820 upodate.

However I found a major flaw/bug with it.

Once I exit PC mode, my keyboard will not come back up. Only way to bring it back is by rebooting.
[Lenovo P11] ZhenMing:
Yes, it pushed to me automatically.

But if you did not get the push, you could download the OTA file from the link above and do the manual update. It was from 820 to 831 OTA update.
[Lenovo P11] ZhenMing:
Is there any error message? So far for my case, I unplug while screen was turn ON/OFF, both scenario gives me a message to turn OFF/ON the PC Mode.

If I unplug the keyboard and exit the PC mode, the soft keyboard did come up and work as usual. Maybe you want to test the setting under the Physical keyboard under settings. The following will by me settings.

However, once you quit the PC mode, all the current apps will be closed and you had relaunched the individual apps manually. Wise versa.

[Lenovo P11] ZhenMing:
How was the update? Everythings fine?

I just notice the Lenovo Official Weibo just posted yesterday on this update. And we had enjoyed it for few days already.
[Lenovo P11] ataman76:
Unfortunately, only me can save the entire ROM, but the producer does not provide it anywhere.
[Lenovo P11] ZhenMing:
The 831 OTA is just a minor update. So, it won't be the full firmware. Unless it is a major to update from ZUI14 to ZUI15.

I expect the major update on our tablet will happened on this year Q4 looking at the current launch of ZUI15 on some of their products.

Just to make me sure to buy it for question no.2 : is widevine L1 just on DRM or netflix as well? Can we play HDR 10 with this device?

Hello,

I am new here and I am totally lost :)

I am planning to buy a TB138FC (Xiaoxin Pad Pro 2022 8GB RAM and SD 870) which has a Fake Global Rom.

I assume this fake Global Rom implies that the bootloader has been unlocked, which means no OTA updates and no Netflix HD (Widevine L3 instead of L1).

From reading this thread, it seems I need to Flash it to restore the original ROM (ZUI 14) and lock the bootloader again to get back the OTA updates and the Netflix HD (Wideveine L1).

However this is where I am lost, I cannot find the information on how to proceed with flashing it to original ROM and locking bootloader. I can only find the tutorial for TB132FU (which is the Mtk 6Gb version of the tablet).

Any help will be most welcome before I buy the tablet!
[Lenovo P11] ZhenMing:
If you want to have the OTA, why don't just bought the one comes with the China ROM instead? That will be Bootlocked and OTA will be provided.

However, you could also source for the P11 Pro Gen 2 with SD870 with WW ROM. That should also comes with the official OTA too.
[Lenovo P11] azazvb:
Because I am buying it from a French marketplace at a very good price ($275 new) and I asked the seller to get chinese ROM but didn't get any answer

I didn't understand your second part of your answer sorry - where/how can I get the original ROM?
[Lenovo P11] ZhenMing:
What I meant was, there is a variants that is call P11 pro gen 2 with sd870soc, which will comes with official English ROM.

[Lenovo P11] galr:
Before buying, does it have variable refresh rate like the 12.7 version?

I mean, is there an option for auto refresh rate that lowers to 60hz if the image is static?
[Lenovo P11] ZhenMing:
These are the refresh rate that is avaliable to TB132FC. I believe there are different type of screen that offers different refresh rate. LCD can go up to 144hz, but the TB132FC is using AMOLED.
[Lenovo P11] ZhenMing:
Guys,

With help from the telegram (in Chinese) members from China, we had the access of the full Chinese ROM file, but the method to flash is different than usual Recovery way. This will need special skill and experience.

If you are interested and desparately want to try, please contact me for more information.

At the same time, there is PE13+ version for those who had rooted the device to try. However, this version may not be having full function as like the ZUI14. Such as the ATMOS might not be working well and the Lenovo Pen won't work too.

If you like to try, do let me know too.

Please be reminded the action above will have the risk to brick your tablet and void your warranty. Please be caution of the consequences.

Thanks to 原来的我 as he will be one of the Telegram Admin that will also help you to get the files above too. You can PM him for more details.
[Lenovo P11] galr:
Thank you. I was not asking if it can go to 144, just wanted to know if it knows to reduce the refresh rate to 60 if the image is still (saves battery). But from your screenshot, it appears not.

Thank you!

Would you buy this tablet today , 1 year after release?

I don't know which one to get.

Option 1: Xiaoxin pad pro 2022 with SD870 and 8/128 (OLED - 600nits).

Option 2: Xiaoxin pad pro 2023 with sd870 and 8/256, but it is a 12.7 LCD @ 144hz (400 nits), metal body and sadly slow 20W charger.

Price is identical - $320

I guess I can live with the 12.7 LCD since it's a good quality panel, but the slow charging is rough.. almost 3 hours to charge it. Also, it seems that the Pad Pro 2022 can hold longer on battery.

Decisions decisions..
[Lenovo P11] ZhenMing:
Welcome, you are right. It will not step down the refresh rate.

If looking at the option, same price, the Option 2 comes with bigger screen with higher internal storage. It is pretty obvious that this will be a better choice. But, this only for my perspective on the selection.
[Lenovo P11] galr:
That's what I eventually did.

12.7 Pro ordered.

Thanks for your input!

Bonjour @ tous,

Juste une question basique : est-ce que vous pensez qu'avant la fin de l'année une version en français sortira pour cette tablette (ZUI15 par ex avec le bon firmware) ou elle restera définitivement en version chinoise . Bien à vous .... jérôme

In English:

Hello everyone,

Just a basic question: do you think that before the end of the year a French version will be released for this tablet (ZUI15 for example with the correct firmware) or it will definitely remain in Chinese version. Yours sincerely.... Jérôme

if you are having TB-138FC you will only get the chinese ROM. But if it can change the language to France, I could not confirm.

I'm no using Netflix, but the Disnye+ did work well on HDR+ Dolby Vision. Just sometime you got black video, but if you minimize and maximize again, it works again.

Of coz as long as you are locked BL.

bought pad pro 2022 870 version instead and it cost 1797 yen with 2 years warranty about 250$ !

anyway for future support will GSI work on this device ?

If you got pad 2022 it's not that bad if you don't mind install custom rom performance a lot faster

and if you don't mind having lcd screen on tablet in 2023 I think at least decent oled panel should be the standard for 2023
[Lenovo P11] ZhenMing:
Sad to say, this model having the least support of custom ROM. If you gotten the 1300t SOC, they had more fun thing to work on.

So far, there is only Pixel Experience, but with plenty of features are not working. Mainly the PEN will not work for sure. You could head to the Telegram group for it.
