I need some help from the gurus.

I managed to brick my tablet constantly going into fastboot loop.

I was trying to upgrade to latest firmware using QFIL but contents.xml contained a reference to rawprogram_unsparse0.xml and failing. I removed those references and here I am - constant fastboot loop mode - can't install recovery or execute any other commands.

How have folks been updating global rom with QFIL with a busted contents.xml?

I was finally able to get into QFIL mode - how do i flash a rom with a busted contents.xml? any other approach? pls help currently in only loop fastbood -

Two errors that are breaking the upate

1. Could not find the meta_cli.exe in the Meta build

2. Fail to load contents.xml: Stop parsing, file not found: rawprogram_unsparse0.xml

I'm assuming both Lenovo active 2 and precision pen 2 work, but there might be cheaper or better alternatives out there.

Don't remove them ... fix the entries.

I had a similar issue (using TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_14.0.714_ST_230403_qpst.zip) and my goal was to go back to stock ZUI ROM and lock the bootloader for Widewine L1 support.

I opened the contents.xml and replaced all (4x) "rawprogram_unsparse0.xml" with "rawprogram0.xml"

I had my tablet delivered with the global ROM (cannot remember what version) and flashed TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_qpst.zip using QFIL. Did several updates over wifi untill it reached ZUI14 (not sure what build) before I locked the bootloader. However after locking the bootlader this message was displayed:

"Your device is corrupt. It can't be trusted and will not boot Visit this link on another device: g.co/ABH"

and then the tablet entered fastboot mode.

Then I used QFIL again with TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_14.0.714_ST_230403_qpst.zip (including the fixes to contents.xml mentioned above) and the tablet was bought back to life with Widewine L1 support.

I then updated to ZUI15 over wifi. All good...

Hi everyone.

I just got this tablet, with global rom (don't remember the version), and flashed it with global rom version TB128FU_S100022_231020_ROW as soon as I got it, and got the hardware not compatible message.

Unfortunately I didn't know about the whole thing before I did that, and so now I can't get to android, no matter what version I flash. Every global version says hardware not compatible, so I tried the CN ZUI 13 rom but it just got stuck on the Lenovo logo if I'm not mistaken.

I've been reading this forum ever since, but I'm a little lost as to what exactly I'm supposed to do.

I saw the region patch, but I don't have a frpinfo partition, only frp, but it doesn't look like the one mentioned for the patch in HxD.

Anyone able to help?

Thank you.
[Device Reviews and Information] cnbbs:
Thank you for the instructions!

I followed your instructions and installation went perfectly right on the first attempt, but the tablet is constantly freezing for a second and there's no audio. I installed the lineage-20.0-20231116-UNOFFICIAL-arm64_bvS-vndklite.img.xz

Any idea how to solve it?
[Device Reviews and Information] cesc1972:
I think if you want to flash a global version to the xiaoxin you have to flash a modified boot.img, you can find them on 4pda, but I can't link them here.

Hi guys, do you know how to get rid of OTA notifications ? I can't update since boot.img is not the stock one and I don't want to loose data with a full reinstall.

[Device Reviews and Information] xd4d3v:
@mamad2000 I personally didnt even need to follow the guide to get google services. I believe there was an option in the app section menu. I suggest that you look there, or start from scratch.

Regarding the Lefile translation, the firmware is for China, we're lucky that most of it also works in English, except a few exceptions like this, that can be easily replaced.
[Device Reviews and Information] cesc1972:
I flashed Zui 15 and didn't like it, I went back to global but not the one I had, the latest one with Android 13 ( TB128FU_S100022_231020_ROW with a modified boot.img )

Everything seems to be working fine, the only thing I don't like is that the navigation bar cannot be hidden anymore, with the magisk module I used on Android 12. The line stays there with gesture navigation and steals screen space.
[Device Reviews and Information] xd4d3v:
Can you post link to global? I wonder who makes these. Are they P11 firmwares adapted to work in Xiaoxin?

There is a great project from the Russian speaking community here to translate ZUI https://github.com/LeyrObnimus/ZuiTranslator

Thanks for the feedback.

I wonder if it is defective, or maybe I just screwed it up with all the flashing.

I'll keep researching.

Thanks.

Hey guys!

So anyone able to help me? I'm really at a loss about what to do to get this thing working.

All global rom versions I tried say not compatible. All chinese 13 roms from different sources just boot to crashdump mode. Lineage 20 and the global rom that came with it kept freezing for a second every few seconds.

I wanted to flash it with the chinese version, but I don't know if I should flash versions 14 and 15.

I have no idea what else to do.

Any help is appreciated.

Thank you!
[Device Reviews and Information] cnbbs:
Finally managed to install global rom with a modified boot.img from 4pda.

Unfortunately the stutter still continues, as shown in the video, but better than with Lineage.

Is this something that can be corrected or is it defective?
[Device Reviews and Information] xd4d3v:
It's actually useful information for the dev working on the magisk module to translate and clean zui, but I've tried contacting @mamad2000 over pm, but he seemed not wanting to help or his answer unclear.

@mamad2000 we would appreciate your help in this matter as long as it's clear and understandable format, rather than posting each individual Chinese app you find.

Zui is a Chinese rom, it will have Chinese apps, and spamming the thread won't help.

I understand there is possibly a language limitation here, but we have many members doing their best using Google translate, with good results.

If you want to help, please provide me via pm, which app (ideally package name) is in Chinese, and why it's important to translate rather than just delete. I will send this info to the dev working on the module.

Personally the only irreplaceable app i found (for the time being) is the package manager.

It has a built in antivirus, which is great, but when it tries to explain the risk of a suspected apk, it's in Chinese.

For everyone else, please feel free to pm me for this too

Hello everyone and thank you very much in advance.

I have purchased a Lenovo Xiaxin Pad 2022 4Gb/128Gb tablet with Snapdragon 680 processor, it has a Global ROM, it has Android 12 with ROM TB128FU_S300168_220916_ROW and Software version TB128FU_RF01_220916. The problem I have is almost every day the tablet freezes after using it for a while (I don't think it's due to overheating) and I have to turn it off by pressing the power button and the VOL- button at the same time. After much reading in the forum and having many doubts, I want to ask several questions:

1.- Is it possible that this Android crash is due to the tablet's ROM?

2.- If I decide to change the ROM that comes with it to a more current one or to the Chinese ROM, is it possible to make a backup of the ROM that the tablet currently has?

3.- Is it necessary to save any information file on the tablet before changing the ROM?

4.- The tablet belongs to my little son and he uses it mainly to play ROBLOX and similar games (sometimes he has also watched Netflix on it). What ROM do you recommend? A Global version like the one I have (but it doesn't freeze) or a Chinese ROM. It would be nice if the ROM could be put in Spanish.

5.- Could someone tell me the detailed process to follow to change the ROM (both the Global and the Chinese ones)? I've read a lot and I think there are several methods to load a new ROM, but I don't want to risk it getting bricked. Although I am not an expert on this tablet, but a while ago I changed a ROM on a Samsung Galaxy and I defend myself well by installing Drivers and Software.

A greeting to all and many thanks in advance.
[Device Reviews and Information] cnbbs:
So I'm still fighting to get the chinese ROM on this tablet.

I've downloaded rom TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526 from two different sources and both boot to crashdump mode.

Downloaded corrected contents.xml, boot images and vbmeta image from 4pda, and tried all combinations of those files with both downloaded roms and same result.

Tried "fastboot --set-active=b" ; "fastboot flash boot boot.img" and "fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img" for both slots with different vbmeta and boot files, with both roms and still same result.

I can still flash the global rom or Lineage with the modified boot images, but with constant stutter that makes the tablet unusable, and really can't seem to get the chinese rom to work.

I did notice that the stutter only happens after booting to android.

I'm starting to get a bit desperate here. Is there anything I'm missing? I'm completely lost and out of ideas.

Anyone able to help please?

Thank you!

I recently bought this TB128FU tablet from an online store and global rom(TB128FU_S100022_231020_ROW) is installed. Every time, I try to open the "developer option", setting app force closes. Due to this this reason, I am unable to check oem unlocking and USB debugging and ultimately not able to unlock bootloader. I have tried to install multiple versions of global roms and zui and everytime my device get stuck in fastboot mode. But I successfully unbrick my device using Lenovo smart assistant. How can I install ZUI in this device while bootloader is locked.

I tried to unlock bootloader using change the serial no to HAHAHAHA method and tried to fastboot sn.img, but device does not go into fastboot mode. I tried power off, then power key plus volume - key, but of no use.

My question is

1. How can I check the USB debugging and OEM unlocking while setting app force closes (bootloader is locked)

2. How can I install ZUI in locked boot loader?

3. Any help regarding the unlocking of bootloader?

- Reinstall Play Services (failed)

- Reinstall the entire Google Play Services suite (failed)

- Reflashing (Failed)

- 2-step authentication disabled.

Any rom I install gives the same problem. I can't log in to my Google Account
[Device Reviews and Information] glees.shin:
1. Were you able to connect your device using adb? You could try to log the Setting app, find out what's causing the crash and reinstall it using adb.

2. ZUI will give you a notice of corrupted device if you attempt to install a lower version of ZUI with a locked bootloader. The current ZUI is 15.0.585 but there has not a firmware packaged extracted yet. You will have to unlock the bootloader then you can flash your device with any ZUI. However, if you want to relock the bootloader, flash it with ZUI 15.0.348 then update to the latest ZUI.

3. Try to enable oem unlock first -> change the sn to HAHAHAHA -> flash with the very first ZUI (13.x.xx I believe) -> put the device in fastboot -> unlock the bootloader using sn.img -> you can now flash the device with any ZUI. Hope it helps

Sorry for my English.

Bought a TB128FU on Ali, it arrived with Global Rom, manufactured 2023/09/25.

I follow the instructions on the third page, https://xdaforums.com/t/lenovo-xiaoxin-pad-2022.4465085/post-87819851, thanks @mcaleb, I install OEM rom ZUI_13.5.365_ST_220526 and update via OTA to ZUI_13.5.476.

Everything works without problems that I detect. OTA shows me the next ZUI14 update but I decide not to update for fear of not being able to change the rom again and problems with Netflix L3 on ZUI 14 y 15 with lock bootloader, according to what I read in this thread.

I want Widevine L1(Netflix) but when reading the entire thread I have doubts if I can close the bootloader without problems with my current rom version, ZUI_13.5.476.

I read from @Lehile and @gitanillo87 that the problems when trying to lock the bootloader are due to not having the latest rom update installed.

Is this really so?

If today with my old rom installed without updating, OTA shows me the next update of ZUI14, I try to block the bootloader in ZUI_13.5.476, will the tablet be blocked?

Thanks in advance
[Device Reviews and Information] glees.shin:
In short, if your bootloader is unlocked, you can flash to any firmware you want and use the tablet normally without L1. By the time you lock the bootloader (to get L1), you must be on the latest fw (currently ZUI 15.0.585). Your tablet will be soft bricked if you lock the bootloader when using any other fw. I read somewhere that if your tablet is manufactured after August 2023, it will require some tricks with the hardware to unbrick your device when trying to downgrade from ZUI 15 to lower fw.

I lost my L1 after updating it to ZUI 15 but other people didn't just fyi.

Hello guys!

I need some advice!

So there is a seller in aliexpress who sells this tablet with installing global rom.

Im not an expert... but im wondering ... Is it worth to buy this tablet?

Or could this rom change cause faulty software? What should I expect?

As I am hungarian will everything translated to my language or will I see chinese app names in google play?

I suspect ther will be no OTA updates.

Can I update it manually to a fully working global up to date lenovo firmware? Or as an incompetent basic user, it is better to buy something else with an official global rom( like redmi pad se( same soc, but there is no gps:( )

Thanks
