Lenovo Tb 371Fc with locked bootloader is not booting after starting before the start programm of "dwas"to reinstall some bloating lenovo apps(, because "allow usb debugged on this PC" was not switched on the whole time) . After that: No booting, you can only seen the sign of lenovo on the top.

After pressing POWER a few seconds , the screen will become dark, then leave the power and start pressing then (both)volume up and down for a few seconds .It will appear Android recovery menu (see attachement above).

By choosing reboot system now, nothing happened , it will only appear the lenovo sign as the left picture above,

if i choose reboot to boatloader there a some possibilitys choosing volumme keys

"Start, Restart bootloader;Recovery mode, Power of,Boot to QMMI, Boot to FFMB"

all menues showing:Fastboot Mode in Red first and at least device locked

I tried it to reboot or reboot to bootloader, but no success, but the solution is simple: see next post

SD card

The problem is you can only choose sd card as portable sd card (,not fore file transfer between PC and tablet) a nd first you have to format sd card into tablet before transfer music and other data from pc on the card. You cant' use it vice versa, not first transfer data from pc to card and then use it in the tablet.

Ladies and gentlemen, from the wonderful 4PDA Russian thread for our device, here are the original boot images for a few versions of ZUI for your rooting pleasure.

Good.

What will rooting bring to the tablet?

Has anyone managed to get Google Lens working on .650? It says I need to update Google and opens the Chinese app store. The Google Play store says everything is updated.
[Lenovo P11] demil7:
Off the top of my head:

- system-wide adblocking with Adaway

- ability to charge device to desired % using Advanced Charging Controller (AAC)

- tons of extra modifications I can't think of at the moment (Google it) that you can make to your phone that normally you can't do...but you have to be careful because you will have full control of your device, so you can easily mess something up

Hi! I noticed that USB-C port seems to be extremely noisy, to the point where quiet listening/watching videos is impossible on most wired setups (ambience, voices, etc. are completely distorted). None of the dongles were acceptable with IEMs and only some with my less sensitive pairs even though all of them were completely fine on all other devices I tried.

Dongles I tried on the pad:

Apple - doesn't work at all <- fixable perhaps?

UGREEN - unusable

Realtek ALC5686 based dongle - fine with HD650

FiiO KA11 - fine with all over-ears

Essager - unusable

Baseus - unusable (and not recommended)

Other devices:

Honor Magic 6 Pro

Xperia 5 II

Redmi Note 11

Galaxy Tab A8

My Desktop (MSI B550 MPG mainboard)

Headphones/IEMs for reference:

Neumann NDH20

Sennheiser HD650

Senhheiser IE 400 & 600

7Hz Salnotes Zero

Moondrop Chu 2

Does anyone else have this issue?

Hello ,

Have you tried with a 68w charger?

I heard information that it supports >45w, but no one has verified it

I recently picked up one of these and am on the stock rim in order to keep L1.

Most apps are willing to use English except a big one for me which is the fanfiction.net app, which does like 15% English at best in menus.

Does anyone know how one might go about changing this? I've set the languages in the app, in the tablet settings and wherever I can, but have had no luck so far.

I've seen wom comments about using commands in order to change the tablet's language or something, but am unaware what those commands would be and whether they'd even work on an unrooted, stock tablet.

I'm on Ziui 15.0.650.
[Lenovo P11] AllexBast:
Find the locales value using the setedit program and change it to en-US
[Lenovo P11] Dannyboy3210:
Hi, thanks for the reply.

I installed the app and tracked down three locations in SetEdit that mention locale and all three were already set to en-US.

Did I miss something or is it perhaps the app (fanfiction.net) itself that may be misbehaving somehow?

Edit: I do not appear to have system_locales in the System Table.

Double Edit: Solved it!

Had to try method 2 from page 14 of this thread that someone posted and got it working!

Hi, so as far as I can tell, I followed the steps from here:

[TB371FC] XiaoXin Pad Pro 2023 12.7 Sharing and support

Hi, I post the theread to exchange information about xiaoxin pad pro 12.7 TB371FC. Some of the issues I have found are as follows, so if you know the way to fix it, please help me. #1 The latest ZUI is 15.0.490 and once you uppdate, you can't...

xdaforums.com

I installed the SetEdit app:

SetEdit SettingsDatabaseEditor - Apps on Google Play

Provides direct access to the Android settings database

play.google.com

I followed method 2, which required I download and installed:

CtsPreconditions

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

www.mediafire.com

Which I believe inserted the line:

"system_locales" "en-US,zh-Hans-CN,zh-Hant-TW,zh-Hant-HK"

Into the 'System Table'

(and possibly other stuff)

I think after that I had to go into the tablet's menu and select English US as the language again and that was it.

It was a few days ago now, so let me know if I forgot something... (If I did I'll try and figure it out and correct my post)

Also, prior to all of this, I had set every option I could find in the menu to English.

After these steps, like I said, I had to go back into the menu and re-select a language as I believe none was selected anymore.
[Lenovo P11] anameeeen:
Thanks. I will try it later today.
[Lenovo P11] benedictsalamat:
I have unlocked my bootloader. Any twrp for this tablet? I can't download the one available in 4pda forums. Any rooting guides for this tablet?

after patching via magisk how to flash in fastboot since I don't have twrp yet.
[Lenovo P11] nickytheshaft:
To see the field you have to change in seredit,the tablet language has to be set to Chinese.

After reboot, you should not set the language through the settings, it will overwright what you did in setedit
[Lenovo P11] Dannyboy3210:
I appear to have accidentally bastardized the process in my zeal to get it working...

Not entirely uncommon for me and Chinese mobile devices (also owned a Mi 9, a Mi Pad 4 Plus and still use a Poco F3).
[Lenovo P11] demil7:
- copy the patched magisk boot image from your phone to your computer where the adb is located on your computer

- connect your tablet to your computer

- open a terminal where your adb is located on your computer

- type command: adb reboot fastboot

- when fastboot loads up, type command: fastboot flash boot [name of patched magisk boot image]

(for example: fastboot flash boot patched.img)

- type command: fastboot reboot
[Lenovo P11] benedictsalamat:
Ok I will try it later.
[Lenovo P11] AllexBast:
It is not necessary to include Chinese. Using the setedit program, you can create a variable "locales" and assign the value "en-US". After this, you need to restart the tablet.
[Lenovo P11] Kamil_leq:
This method worked on 15.0.490(bootloader locked) but the battery icon disappeared.

Is there a fix for battery icon? And also, if i update to lastest version will the language change back to English/Chinese? (Now is set to pl-PL and some settings are in English)

Edit

I found two ways to fix the battery icon ONCE, after the screen turns off the battery icon disappeare again

First(more time consuming)

1. Settings>advanced features>Pc mode

2. Enter the PC mode

3. Reboot device without exiting Pc mode

Second(quicker)

Settings>notifications & control center>custom status bar>enable custom(you can just enable it and disable it immediately)

ブートロックを解除せずにバージョン 154 を 405 にダウングレードし、ブートループに入っています。 「fastboot set_active a」と「fastboot set_active b」を試しましたが、うまくいきませんでした。ループから抜け出す方法はありますか?
[Lenovo P11] sasasa3:
From154 to 405, You need to unlock bootloader otherwise the device go into bootloop.

So the only method you rescue your device is unlock the bootloader now.

You check your Serial number in your fastboot, then Get the SN.img from

http://cdn.zui.lenovomm.com/developer/tabletboot/"YOUR SERIAL NUMBER"/sn.img.

Hope you can save your device.

I couldn't unlock it. Is it because I don't have USB debugging turned on? The bootloader is just stuck in a loop, so I can't do anything.
[Lenovo P11] Ledesma90:
Maybe if you go into recovery mode, you'll get a reset option and you won't have to unlock the bootloader
[Lenovo P11] aradai:
Thank you for your reply! I can't enter recovery mode. You will be returned to the bootloader immediately.
[Lenovo P11] Ledesma90:
What version did you have before flashing and what version did you want to put on the table?
[Lenovo P11] aradai:
Downgraded version 154 to 405.

Then it went into a bootloop.
[Lenovo P11] Ledesma90:
You could try uploading to the 440 and you might not need to unlock the bootloader, and if that doesn't work you're going to have to unlock with sn.img (Some commented that from 405 to 440 didn't need to unlock) you'd have to do it by fastboot.
[Lenovo P11] aradai:
I tried flashing 440 but it didn't fix the loop. I'm ready to unlock it but it's not working. Is there any way to get it out of this state?
[Lenovo P11] Ledesma90:
On this page you will be able to download the sn.img file https://m.zui.com/iunlock and the command would be "fastboot flash unlock sn.img"
[Lenovo P11] AllexBast:
You need to use QFIL to save the frp partition and change the last byte from 0 to 1 and save it in the HxD editor. Then flash the modified partition. After this, you can unlock the tablet.

I don't really understand it, so I haven't moved it from where I downloaded it.
[Lenovo P11] Ledesma90:
Please place the sn.img file in the folder "Minimal ADB and Fastboot" and execute the command that I gave you correctly without errors "fastboot flash unlock sn.img"

Did you download the sn.img file from the Lenovo website?
[Lenovo P11] aradai:
Yes, I downloaded it from the Lenovo site.
[Lenovo P11] Ledesma90:
I think the problem is your sin.img file or your version of ADB and fastboot is very old, I can't think of any other problem...

Can you share your tablet serial number with me?
[Lenovo P11] aradai:
Is the serial number the one shown on the bootloader screen or the one written on the box?
[Lenovo P11] AllexBast:
Open sn.img using HxD. Find the serial number on file. It should fit in the fastboot. If it doesn't match, it needs to be changed. HxD needs to be downloaded from this link https://mh-nexus.de/en/hxd/
[Lenovo P11] Ledesma90:
The one shown on the bootloader screen please

This Abd lacale setting doesn't require root or bootloader unlock.

Just open the developer option and enable adb debugging.

Neither adb nor this app has any possibility to brick the device.

I don't know the manipulation with lenovo utility, but TB371FC is sold only in china so probably you cannot change it to US Version.
[Lenovo P11] aradai:
I enabled ADB debugging at the very beginning, wrote the ROM from 154 to 405, and it's been stuck in a boot loop ever since. I think it's probably been initialized, so I don't think ADB debugging on the tablet is enabled. However, I can't do anything from this point on.
[Lenovo P11] AllexBast:
If the "oem unlock" item is not enabled in the developer settings menu, then you need to change the frp partition using QFIL by changing the last byte from 0 to 1. It's so simple, but you don't know what to do. I restored my tablet in half an hour, including searching for instructions.
[Lenovo P11] AllexBast:
To begin, press and hold 3 buttons on the tablet. After 10 seconds the tablet should turn off. The USB cable must be disconnected. After the tablet turns off, charge it to 100%. Next, you can install QFIL and drivers from here

https://xdaforums.com/t/guide-unbrick-lenovo-y700-tablet.4509297/

The firmware : https://xdaforums.com/t/tb371fc-xiaoxin-pad-pro-2023-12-7-sharing-and-support.4642987/post-89251897

Firmware cannot be flashed via qfil until the bootloader is unlocked.

Issue with sd card in Lenovo xiaoxin pad pro 12.7

If I take a sd card 500gb, 1TB or 2 TB from Ali for 5€, I have to format sd card first. If I fill them outside with movies and mp3 and put in the device, first i can show this movies, but f I turn off device or reboot, the sd card shows issues and want to format again.

Is this a bug or is the sd card with 500 GB or more bad or to big for the device? If I format the sd card outside, which kind i have to choose to format it? Is there a solution?
[Lenovo P11] siamese007:
The SD card that you've got is fake. The seller of this item is scammer. There is no TFT SD card with 500GB or bigger at this price. Just trash it.

I plan to buy Xiaoxin Pad Pro 12.7 Qualcomm version but still gathering reviews and information. I'm worried about unlocking the device since there is/are someone(s) who cannot unlock it with official method. I don't have Netflix or any others so No worries about DRM Widevine L1 working or not. Just for usual game and movie purposes. Only worried whether or not the Play Protect fo its Stock ROMs will work. Since some games require Play Protect to work or they'd consider the device as hacked and possible for cheating.

Good luck for the current users.
