How To Guide [TB132FU-Mediatek Kompanio 1300T] Convert from Chinese to Global

[als_bvg]

NEW: Install official Global ROM on Chinese TB132FU running ZUI 14 or Fake global​

DISCLAMER: Flashing on TB132FU is pretty much safe and a hard brick has not occured yet, but do it at your own risk. If anything goes wrong you can return to ZUI 14 using one of the restoration methods listed on the FAQ thread. ALL YOUR FILES WILL BE DELETED. Make a backup of your personal files before proceeding.

Current version: TB132FU_S000094_221117_ROW
To see what works and what doesn't check below.

To flash this version you will need:

1 - A computer running Windows
2 - Flashtool (attached to the thread)
3 - ADB drivers or UsbDk drives & MTK drivers
4 - ZUI 14 installed on your TB132FU. If you have fake global you can flash as well, but having ZUI is recommended.
5 - Firmware file
6 - Attention to the really detailed tutorial below.



How to flash

Preparation:
1 - Download and install the drivers provided above. If you already have them installed skip this step.
2 - On your computer create a folder on your Desktop. Name it LENOVO.
3 - Download the firmware file (download link provided above) and un-zip it inside the LENOVO folder on your desktop. So inside your LENOVO folder now you should have a folder called TB132FU_S000094 Global.
4 - Download the attached flash tool and un-zip it inside the LENOVO folder on your desktop. Now you have a folder called TB132FU_S000094 Global and a folder called MTK_Flashtool.
5 - Power off your TB132FU and disconnect it from your computer in case you have it connected.

Flashing:
1 - Go to the LENOVO folder, and open the folder MTK-Flashtool. Inside this folder find flash_tool and double-click to open it.
2 - Once it opens click the TAB download. Do not click the green arrow.
3 - For the Download agent click Choose. Navigate to your Desktop > Lenovo > MT_Flashtool and select the file MTK_AllInOne_DA_onyx_signed
4- For Scatter-loading file click Choose. Navigate to your Desktop > Lenovo > TB132FU_S000094 Global and select MT6893_Android_scatter.txt. You will see two files with the same name. Click the one with the paper with lines icon. Wait for it to load.
5 - For Authentication File click Choose. Navigate to your Desktop > Lenovo > MT_Flashtool and select the file auth_sv5
6 - You will see white and green lines below. Scroll down and find the line that starts with lk_a and UNMARK it. All the other options should be marked, only lk_a should be unmarked.
Ex:

7 - Click the green arrow DOWNLOAD and plug in your tablet. Wait until it completes flashing the firmware.
And done. Once it is finished you can unplug your tablet and turn it on. You now should be running the latest global rom on your TB132FU;

What works:
Google Sync
HDR with true black
Productivity mode (PC mode)
And almost everything else. I'm still testing it.

What doesn't work:
OTA - once a new update is available it will be needed to be flashed manually losing all data. OTA did not work on a previous version.
Ultra-fast charging. It has Rapid charge but not the super fast charging available on ZUI
Some users reported L1 when flashing this global.
For users who lost L1 status, no solution to get it back from L3 yet. :/
"Scroll to the left" on the home screen to access the media center will not turn off even if you try manually setting it as off.
Time-zone issue: Factory reset it after the first boot to get it fixed.
You tell me what else is not working.

Thanks for the detailed explanation.

Some cuestions that you may have an answer for:

1. Has the bootloader to be unlock? What happens if I have the bootloader lock? (I lock mine with zui 14 in order to get L1)
2. Is there a way to change region code like in others lenovo models? Will it have any impact on OTAs?
3. Can you rollback to zui 14?

Thanks in advance. I think that will be able to have a full working rom with OTAs and L1 eventually. This is a huge step forward

What doesn't work:
Ultra fast charging. It has Rapidy charge but not the super fast charging available on ZUI

Out of curiosity, does the Chinese model have an Ultra fast charging?
My Global P11 Pro gen 2 does Rapid charge and my cable display caps out at 10w which I wouldn't say is rapid...
Same cable and charger gives me much faster speeds on my Galaxy S22U.

It does. The Chinese running ZUI has Ultra-fast charging with the original cable and charger.

1 - You don't need the bootloader to be unlocked to flash this global version. I had Zui 14 with a locked bootloader and OEM locked, and the flashing worked. The OEM toggle will not be available once you use this version. It says you need to connect to the internet or contact your carrier.
2 - No way to change the region code so far. OTA will not work as described. It was tested on an older version. It will download and try to install but will fail. This is the latest rom so no OTA updates so far, we will have to wait to see if it will be the same.
3 - Yes, you can roll back to Zui 14. I did that quite a few times during my tests. Bricked the device more than 20 times and was always able to roll back to ZUI.

Thank you so much!
Generating User Accounts is working too? Wanted to use the tablet for the family, but ZUI doesn't offer accounts and Google Family doesn't work.

Hi. Thank you very much for the excellent work! Testing, so far so good. Do I have an L1 or am I misunderstanding something? Screenshot attached.

Thanks for the great work you do.
We have successfully implemented the global implementation.

My tablet is formatted with the SP Flash Tool. The serial number was lost at that time. (When I looked in the settings, the serial number was 0123456789ABCDEF.)
The serial number itself was recovered by rewriting the proinfo.bin. I think this formatting probably caused the Widevine-related settings to disappear and become L3.
I ask other L3 users, did you format with SP Flash Tool or python?

 

[tylerdanarg]

Flash mine today from ZUI 14 with bootloader lock, L1 and Google Play Certified to Global ROM and I kept L1, Google Certified Device and everything Is working. Even fast charging.

Thanks a lot! Let's see what happens when an OTA Will be available.

Generating User Accounts is working too? Wanted to use the tablet for the family, but ZUI doesn't offer accounts and Google Family doesn't work.

I bought it for my daughter to use and have Family link for her Google Account and its all kinds of wonky (it shows my daughters account under Accounts then it vanishes. the only way I can add it back in is by signing into the Play store but then after an hour or so it goes. Works fine with my google account. Damn Family Link!)

(its on 14.0.413, and has an update pending for 14.0.640 ST). Not a clue how to check if its a modified ROM or what, but was going to try the above and see how it gets on.

 

[tylerdanarg]

Just to clarify fast charging Is shown on the screen but I don't if it's 10w ir 30w. I Will do some measures today and keep you posted

Try the AccuBattery app, it may not be accurate, but it shows the charging current. I don't want to charge it yet. I will first discharge it and then install this app and start charging. It's convenient because it shows time to charge up to 100%.

Thanks for your input. I formated it before using the option "format + download" and serial number is now 012345678ABCDEF. I can try doing what you did with the file proinfo.bin. Any specific tutorial you used?

Go to your settings menu. If you see the word ZUI anywhere, it's the Chinese model and you can flash the global if you want.

Thanks! Yep, I have ZUI! I think its the family link attached to my daughters Google account that makes it annoying, but can't see any down sides in going to the Global to be honest. Can't get any worse... can it?!

It shouldn't get any worse lol, but if your daughter is a kid you might benefit of a global rom, it has Kids space and the possibility of creating multiple users.

Awesome! Big thanks.

What I did.
Install Python and mtkclient on a windows 10 computer.

python mtk rl --skip userdata "Destination path"
Backup everything but the user data with the above command

Open the backed up proinfo.bin with HxD and rewrite the serial number at the beginning.

python mtk wl "Destination path"
Flash the rewritten proinfo.bin with the above command.

I used to be able to do this, but I just tried it with a globalised tablet and it didn't work: the BROM mode (press power and volume plus simultaneously to connect the cable) is difficult to connect and even if it does, an error message appears and the process stops. When I get more time, I will switch back to zui14 and give it a try.

Nice one! I can test it tomorrow. It's actually easier to pull the proinfo.bin file using MTK META Utility by using option Dump NV region. I was able to get and edit the file. Not sure how to flash it again on ZUI with a unlocked bootloader. But that's a start. I managed to get another Serial number by flashing another user's backup, but I still have L3, so might not be connected. I'll keep trying.

I actually managed to get it back by flashing the edited proinfo.bin file using this command on ZUI with unlocked bootloader and OEM unlocked: fastboot flash proinfo proinfo.bin

Now let's see if it impacts or not L3. Testing...
