I didn't want to change the ROM either but had to as I found out I had the Chinese firmware and I rebranded to USA firmware.

I took a look and it's a really good price if your down to $500 for 4GB 64 GB version , I say go for it.
[Huawei Mate 9 Questions & Answers] mazinya:
I have ordered the device but now I am wondering which model is it as they dont specify and although it says global version they dont say the exact number and I hope this is not a Chinese version. I asked them and they cant tell.

Could anyone try and guess according to the page specs which firmware is that? is it MHA-L29? MHA-L09? or other? EU version? Asia? US?

[Huawei Mate 9 Questions & Answers] 5[Strogino]:
They wrote "Dual sim" in description, so it can not be L09.

They sell from HK - it should be Asian version, but I'm not sure on 100%
[Huawei Mate 9 Questions & Answers] mazinya:
Can it be a MHA-AL00 Chinese variant? (i hope not)

and if its MAH L29? thats European version?
[Huawei Mate 9 Questions & Answers] Csetoue:
I'd like to know that too.
[Huawei Mate 9 Questions & Answers] mazinya:
Its Asian version
[Huawei Mate 9 Questions & Answers] Csetoue:
So, not rootable and not unlockable, right?

The main purpose of this thread is to unify all the useful web links, mainly other XDA threads, that contribute to improve and expand the development, guides, discussions and all other useful sources of data related to our device.

"HOW DO I KNOW IF THIS IS MY DEVICE?"

The device we are talking about here is a Huawei Mediapad T1 10, which consists in at least 3 different variants:

- LTE variant (T1-A21L)

-WiFi variant (T1-A21W)

-LTE chinese variant (T1-A23L)

They are exactly the same device in terms of hardware and software (this one vary a little), the only difference is that one has SIM slot (T1-A21L) and the other one no (T1-A21W).

An important point to keep in mind is the codename of our device, which is a technical name all Android device have and which identify exclusively to the device. This is very usual in development threads such as ROMs and Recovery threads, so you might see it in the thread title.

The codename of our device is

hwt1a21l

-Technical information of our device.

Specs are from the LTE variant but it applies for the WiFi variant expect for the SIM slot: [url]http://m.huawei.com/ukmobile/consumer/tablets/detail/mediapad-t1-10-uk.htm[/URL]

If you still have doubts about this topic i suggest you to ask you doubts or check other people's doubts.

RULES:

1- Please only discussions related to our device (Huawei Mediapad T1 10 T1-A21L/T1-A21W). See previous paragraph to know if you own this device.

2- If you want to report an issue or any other subject related to an existing rom, recovery or other subjects try to keep the conversations in the respective thread of what you want to talk. It's not mandatory but it's a good way to keep conversations in the proper thread so other people can check it.

I had my pc broken quite amount of time and i could not work on some roms that i was testing. I was planning to upload CarbonROM Kit Kat for our device, but unfortunately i see a lack of users activity for this device which makes me think that maybe it is not very relevant to create and upload the builds (which takes much more time than what it seems, and my time for this activities is quite limited).

If i see more interest for this then i could upload the rom, and maybe future ones.

Dear mustang_ssc, I don't know if you are still wondering about usefulness of uploading CarbonROM KitKat for th t1 10 ? There is an important interest from my side for more than 1 device.

If I can be of any help to avoid important workload to you, I ll be pleased to contribute.

+1 to that. I have the stock rom with root access.

The tablet mainly sits and collects dust right now so I wouldnt mind using it for testing.

Let me know if I can help.
[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Though the bug are not solved yet, I will probably open a thread for the rom this weekend so people interested like you can install it, test it or keep it on his tablet without mind the current bugs.

I will keep you informed :)

[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Don't worry, i will open the thread and people with the WiFi variant will be able to download it. I want people with the LTE one to test it because i own the WiFi Varian as well.

Also a reminder for everyone:

Keep in mind that the rom still has some few critical bugs which you may not be happy to flash the rom. The main bugs are:

-Camera not working

-Notification led not working

-Weird bug with the Play Store which does not allow to use it unless, on my experience, you wait for about 1 day to be able to use it.

[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Alright, have good and bad news, let's start with the good one:

I have a completely working 5.1.1 Android ROM (EMUI 3.1) from the T1-A23L which works on the LTE and Wi-Fi variants (T1-A21L & T1_A21W), big thanks to [MENTION=8534276]tenderVeteran[/MENTION] who sent me this ROM and informed me about it. This means we finally have Lollipop for our device and we have the possibility to port another Lollipop ones.

The bad new is that i need to make it flashable but for some reason it does not boot. I need some more time to figure out about a solution on this topic and i will publish it as soon as i get it booting.
[Huawei MediaPad, T-Mobile SpringBoard] Apexaddicted:
Glad to hear about the progress! Cant wait to try it out. Please let us know if there is anything we can do to help.

Additionally...Ive been looking for ways to compile a custom kernel for the mediapad. Have you tried this yet?

Rob
[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Yes, i have tried to compile some ROMs with the kernel source from our device got from the official Huawei website a lot of times but I'm facing a lot of issues on the compilation process.

You can find the stock kernel source for our device on my github profile: https://github.com/Mustang-ssc/android_kernel_huawei_hwt1a21l

I also have uploaded the device tree and propetary vendors i created but i think i would need to update them.

The current blocking point from my side is mainly what seems to be a missing driver file from the lcd screen which for some reason it is not present. This is shown when i start the compilation and it fails due to that missing specific file for our device.

I need to contact to Huawei in order to know why this is missing and continue trying to progress on the compilation, but if this driver file is a must to have it and Huawei does not provide it to me i think it probably would mean a game over for the real and big development, so let's hope we can progress on it.
[Huawei MediaPad, T-Mobile SpringBoard] ddscentral:
Hello there. Sorry for resurrecting an old thread but I'm also interested in getting something ported to this device because the stock software is no good. I have the LTE variant, T1-A21L.

Kernel does build fine from source using Huawei's build.sh script and toolchain from their open source download (T1-A21L open source code.zip).

I do have some experience working on Android ROMs (mainly Android x86 stuff) and could help with porting.

Mediapad T3 7- does it have a voice calling functionality?

Dear Forum Members

someone recommended Huawei Tablet Mediapad T3 7. does it have a voice dialling functionality like normal phones?

Looking forward to your helpful comments

Verogg
[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Send me a PM for this, i may be interested :good:

The main problem i am facing at this moment is the kernel compilation with LineageOS source and toolchain, which throws forbidden warnings and aborts the compilation.

I merged our stock kernel source to the Cherry one from LineageOS official repo although probably it is not functional at all and the source importation of our kernel source was not done properly, but i guess it's something. You can check this on my github profile.

EMUI 3.0 didn't boot

Hi mustang..ssc, I'm a new member! I downloaded and installed your version for my Mediapad T1-A21L. It was perfectly installed with the CWM on the tablet. But it don't boot at all! Any idea what i can do or made wrong or forgot to do?

Thanks in advance
[Huawei MediaPad, T-Mobile SpringBoard] sd11aa:
have you unlocked the bootloader?if not,I don't have ideas.or you can flash the stock rom and wipe /data and /cache,you can use stock recovery in stock firmware to flash the huawei update.APP
[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
I need someone with the T1-A21L variant to test my TWRP recovery.

Requirements:

- Bootloader unlocked.

- Knowledge on how to flash recovery with fastboot

- If possible have the stock ROM which comes with the device, this means without my custom rom based on stock.

- Backup your device content and ROM (optional).

Quote me and i will send you a PM.

I'm planning to release it on a few days, but first i need to test it on this variant.

Thanks.
[Huawei MediaPad, T-Mobile SpringBoard] sd11aa:
I want to help you to test it
[Huawei MediaPad, T-Mobile SpringBoard] mustang_ssc:
Yes seems indeed something is wrong for some users. I recommend you the following:

- Make a backup of your stock ROM which came with the device.

- Flash my ROM.

- Restore the boot.img from the previous ROM.

This should work if im not wrong. I don't remember if Philz Thouch had the possibility to restore only the boot.img but if not let me know and i will send you my TWRP test build so you can try it.
[Huawei MediaPad, T-Mobile SpringBoard] sd11aa:

Hi mustang, I haven't any more the stock ROM from Huawei. I was fed up with Huawei - its Android KitKat-version, its support etc. Later on I had to recognize that no upper Android version exists for this tablet, so back to Kitkat. I downloaded from Huawei Germany and UK the firmware ROM for this tablet, but both cannot be installed. The installation aborted after a few seconds. The only ROM that bootet perfectly is the Carbon ROM! But it doesn't run really well - Apps are ending and many new starts. So I would test your TWRP immdiately, when you finished it.
[Huawei MediaPad, T-Mobile SpringBoard] sd11aa:
only the stock recovery can flash the stock ROM，philz touch recovery and twrp recovery are not support flash huawei stock ROM，if u need it，I can send you the Chinese version stock ROM and recovery,download the updata.app and put it into /sdcard/dload, flash the stock recovery,shut down the devices and put power,volume up and down to flash the stock ROM(huawei update.APP). it's based on Android L and it's Chinese version(this recovery can only flash this ROM)
[Huawei MediaPad, T-Mobile SpringBoard] Fazer37:
Hi sd11aa thanks for your answer. So please send me this Chinese version of the stock recovery for flashing one of the two stock ROMs I've already downloaded. And if you are thinking it's necessary, the Chinese stock ROM too.

Command not allowed

Hi.

I bricked my tablet a few years back, and pretty much gave up on it until now.

I've been trying to flash the stock rom with fastboot, but I get a "Command not allowed" error whenever I try to execute a command.

From what I gather this is because of a locked bootloader. Is there any way I can unlock the bootloader with fastboot?

Yes, you can find here the EMUI 3.1 build (Lollipop 5.1) for the T1-A23L model. Build number: T1-A23LC233B117:

http://update.hicloud.com:8180/TDS/data/files/p4/s10/G731/g0/v63645/f1/full/update.zip

Below the changelog:

http://update.hicloud.com:8180/TDS/data/files/p4/s10/G731/g0/v63645/f1/full/changelog.xml

Proper credits to [MENTION=9741044]timea[/MENTION] who somehow found the links and reached me with them.

About the installation:

I have not tested this as I no longer use the device, but [MENTION=9741044]timea[/MENTION] did and found it is working correctly.

If you have the T1-A23L model it might work by just installing the update.app file, unless region restrictions are the case.

Requisite: You will probably need an unlockeed bootloader.

The installation process that should work:

1. Backup all your data and rom using twrp, save them in your pc. Once done flash again the stock recovery. This is not mandatory but suggested.

2. Extract from the update.app the img files.

3. Flash system.img and boot.img using fastboot:

fastboot flash system system.img

fastboot flash boot boot.img

4. Reboot and wait to boot (should not take more than 5 minutes)

If there is something else I might have missed maybe [MENTION=9741044]timea[/MENTION] can help on it ;)

Hope you all can update this device deserted by Huawei.
[Huawei MediaPad, T-Mobile SpringBoard] Ali_Shaikh744:
Hi Mustang. I would like to ask if you would be willing to help me install this custom ROM on a T1-A21L? I know this forum is really old and I understand if you don't have the time to help me.

I have never installed a custom ROM before so it might require more patience. For step 2, where exactly are the image files located and do I extract it to my PC? For step 3, how exactly does one use "fastboot" to flash "system.img" and "boot.img"?

Thank you.
[Huawei MediaPad, T-Mobile SpringBoard] ndreisg:
Hi

Tool to extract the image files from update.app:

https://xdaforums.com/showthread.php?t=2433454

The fastboot tool is contained in the Android Studio command-line tools. You can find them here:

https://developer.android.com/studio/command-line

To get into fastboot mode you need to follow these steps:

Turn off the tablet completly.

Hold Volume Down button and connect usb cable to phone.

Wait until you see fastboot mode on the screen.

If you see "PHONE LOCKED" on the bottom of the screen you will need to unlock your bootloader first.

Here are instructions how to get a bootloader unlock code (note: not free!): https://www.dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code

Good luck
