Mediatek MT8173 & MT8176 development
Hi folks, after I've long been working on my device and only made little progress in building LineageOS for my Xiaomi Mi Pad 3 I decided to look for other developers with similar devices.
My Mi Pad 3 (codename: cappu) is a tablet based on a Mediatek MT8176 SoC. It was launched in April 2017. The tablet comes with a 7.9" display with a resolution of 2048 pixels by 1536 pixels at a PPI of 326 pixels per inch. It is powered by a 2.1GHz/1.7GHz Hexa Core processor ( 2 x 2.1GHz Cortex A72 + 4 x 1.7GHz Cortex A53 ) and it comes with 4GB of RAM. The tablet packs 64GB of internal storage that cannot be expanded. It was shipped out with Android 7.0 (Miui) and is still on this version).
Two months ago Xiaomi finally released Kernel Source Code for my device. It was broken, but I fixed most of the conflicts, streamed the kernel up to latest linux-stable and added some features. I also tried to build LineageOS & AOSP trees, but I have to admit, I'm starting to get desperate. For this specific SoC - even it's predecessor MT8173 - there is no activie development. And that is what I am looking for!
I collected some devices that either use MT8176 SoC, or the older MT8173 SoC. Some of them have Kernel Sources, which I listed and linked below.
All questions, requests for help, suggestions, ... are welcome. If you own any of the listed devices feel free to write and help. This thread is also on Reddit.

First thanks for your initiative! And I am very interested in obtaining a Custom ROM for my Teclast T10 E3C5 device with the aforementioned MTK8176 Chipset. I cannot help you with development but are open to test it and report bugs.
Hi Goayandi,
I'm not sure how many experienced ROM developers you will get. (I'm not one of them. I have compiled and modded existing ROMs, but never ported one.) I've heard several people say they will look into building a custom ROM for mt8163 or mt8173. But that's always as far as it gets. They never come back with any results. So I was just curious, what are you getting stuck on?
As far as I can tell, one major problem with porting to Mediatek is that they modify a lot of Google's OS code like frameworks and libraries. I do see that you already have some MTK customized repositories in your github library. You may have to do some reverse engineering of the stock ROM to confirm that the MTK changes are the same ones you have in your repos. Yes, that's a huge pain. It's also likely that MTK's patches for mt81xx and mt67xx, which is probably what you have, are pretty different.
One suggestion I want to make is to start out with a ROM that's as close to stock as possible. That means building a plain AOSP build NRD90M. This will reduce as many trouble-causing variables as possible. That's how I would do it. If you accomplish that, it will be easy to move on to higher Android versions or LineageOS, etc.
I would also use the prebuilt kernel for now. There is not much point to compiling your own for the same reason I just mentioned. A lot more variables would enter the equation. (Unless maybe you can test it independently with the stock FW.)
Any chances of giving TeamMAD access to one of these devices?
I have a Teclast T8 stuck in fastboot mode. No recovery, no system. adb cannot see the device. Is there a way to recover from that?

In T10 thread I have heard of same kind of issue. Disconnect battery (solder) or wait for device to die, then charge and it should be fine

I tried that. That would work if recovery were bootlooping, and system were intact. In my case, my T8 cannot get to system. The Teclast Logo goes through its animation on startup, then gets stuck there. Holding volume up and power gives me 3 choices: recovery, fastboot, normal. Recovery and Normal are both broken. Fastboot is the only one I can do. How to recover from that?

You need to reflash firmware/rom with the sp flash tool.

You should flash stock firmware on your tablet with SPflash tools. Search for Mediatek SPflash + your device name in Google. Flash procedure should look like this:
FLASH Mediatek device
- Unpack FlashTools, and Click on Flash_tool.exe
- Select "scatter-Loading" and search MT8173_Android_scatter.txt in ROM
- Wait file to be added into Flash Tool
- Select "Download Only" or if upgrade "Firmware upgrade"
- Turn off your phone (and don't turn on the phone).
- Press “Download” button to start
- and connect your phone into the computer via USB data cable.
- The process will start and a red progress bar will appear after color purple, yellow.
- And green circles display
- Finish !
- You can now safely disconnect your phone and turn it on.
So you should look for your ROM/FIRMWARE and than flash it. Key step for you is to turn of the tablet, push download button in SPflash tools, and then connect USB to the tablet. Flash will then start!
But Google for instructions on how to use SPflash
Thank you, BiG_FooT and fastmix! Leaving it in power off state before SP flash was the missing step. I don't know how I missed that in previous Google searches. Fully working tablet now.
I now have two of these things. If you (or any others interested in developing this Mediatek) want me to use one of my Teclast T8s for testing for you, let me know.
Has anyone successfully flashed the firmware??
The system.img for all the ROMs is corrupt
Hi! I have an Alfawise Tab (rebranded JDTAB 01) with MT8173 chipset and android 6.0.
I managed to find the stock firmware and recovery, so i tried to port this TWRP recovery: https://forum.xda-developers.com/mi-pad/development/recovery-twrp-3-2-1-0-mi-pad-3-cappu-t3744185 unsuccessfully, maybe because of the different android versions(?)
I don't know....
Does anyone know how to port- build a custom recovery for these chipsets (mt8173-76)?
Or know if there is a working TWRP based on android 6.0 and these chipsets?
So, is there still any development? Where kernel-sources for Teclast devices can be found?
What an utter failure. Of both the manufacturers and the community.
It's fairly clear that the problem is hardware fragmentation. There is just too much diversity in Android hardware platforms, even too many different ARM-based CPUs, and too few users on many of those to justify a major development effort for any of them.
The moral of the story must be: if you want your tablet to remain useful for more than a couple of years, don't buy a cheap Chinese generic one made by a company that isn't a famous global brand. Stick to hardware that has sold in the millions.

What we really need to do is reverse engineer a few roms already built for these chipsets, then see what they all have in common. This will help us figure out what needs to be done to the kernel, and what firmware we need.
Any news? Has anyone tried to flash GPD firmware on one of the other tablets with the same chipset? I have a Chuwi Hi9 with MTK 8173 and I would love to be able to change the ROM, the default one sucks big time. I actually bought it because it had the same chipset as one of the GPD devices.
Where To Start??

Hi,
If I were you I would start by having a really good look through the MTK_X20_BASE_AOSP open source code here https://github.com/archermind/MTK_X20_BASE_AOSP
In that you will find all the required mtk binary's and documented associated google dependency's and stock mtk app's needed. Dig through all the make files and compare your project_confg which should be in your system/data/misc on 6.0 and vendor/data/misc 7.0 with the one in that source to see whats built.
Because it's mediatek it's messy and things are all over the place but after days of reading it you can kinda start follow the rabbit eventually :laugh:
Take what you need and assemble it into a nice logical fashion using a experienced dev's work as a example and try a AOSP build if that works then try Lineage.
When you have things stable follow others who have stepped up in firmware version.
Most things should work if you have a working kernel.
Best place to start would be HERE it's invaluable :good:
There are other places and make's for BT WiFi GPS etc etc so ensure to explore it well.
Obviosly get the blobs from your own device if poss else pinch them form that source and give them a try it's all trial and error.
If I ever find the time I may join you one day to build a rom for the Lenovo Tab2 mt8165 please note most of these mt8xxxx have a equivalent mt67xx/mt65xx see my sig below for a example.
Good Luck and Happy building :fingers-crossed:

Hello!
Do I have a chance to do this with my teclast T8 device if I don't have even kernel-source code? For now I've ported most of firmwares different from my stock ROM (MIUI, ZenUI etc). But I would like to upgrade android version ( Nougat to Oreo) if it possible. Since not so long new device ( alldocube X) was released on same chipset (mt8176) with installed android Oreo, maybe this may help some way?

Hello To All
I have a Teclast M89 That I rooted with Magisk and have a working TWRP for backing up.
I am very interested in Testing Kernels and new Roms.I have already wiped and reflashed device a couple times -now Everything for testing,flashing, and booting has been verified.
@Goayandi
Just stopping by to say thanks for this, used some stuff from here for lineage-12.1 on Fire HD10
https://forum.xda-developers.com/hd8-hd10/orig-development/rom-lineage-12-1-t3953677
3 years ago somebody downgraded somebody I met at the internet successful my Samsung J5 to Android 5.
Now I think about the possibility to downgrade my Samsung A7 (A750GN) to Android 4.
Would it be possible?
In know with such a questions a lot of people want to know why.
It's simple.
I love how 4 looks.
I could still enjoy 5 if I have too.
And Android is gone the same negative way like Microsoft with Windows 10.
Every new Android Version has more and more rubbish included I don't use and I don't want,
Today is (for me) my Android Version a overloaded fat elephant with so many bad functions I can't turn off.
I would like to have a "Android Lite" and I would like to have a Android that looks like 4 or 5.
But would it be possible?
I have never ever done something like this for myself.
That last time with my J5 somebody installed a remote control on my laptop and I plugged in my mobile and this guy has done everything remote controlled.
I have still to today no idea who he was and from where he was.
But it worked fine.
He downgraded my J5 to Android 5 and he changed something in such a way the mobile never ask for a update and when I try to force a update I get the wrong answer the newest update in installed.
Absolute great.
That is what I'm looking for with my A7.
Any ideas?
It is NOT possible to downgrade your A7 to android 5.
When a new phone comes out , for example the A7 2018 , it was launched with android 8.
It can not be downgraded to any version below the version it came out with.
Even after updating from android 8 to the latest android 10 , i don't think it is possible to even downgrade to android 8 again (because samsung updates, patch your phone with the new update.)
Galaxy J5 was released with android 5 touchwiz, the android 5 system customized by Samsung.
The person who was connected to your computer has installed a custom rom (probably an AOSP rom , as you described being a "lite version".)
AOSP roms are roms without the Samsung add-ons and customizations , created by developers here on XDA.
For the moment , an AOSP android 10 for A7 2018 is not available , but there is another way to get a "lite " version of android 10 on your device.
As it needs a lot of reading and understanding on android development, i do not sugges you doing so .
It is called GSI and you can find by reading in the correct thread , for example :
https://forum.xda-developers.com/galaxy-a7/help/how-to-install-gsi-samsung-galaxy-a7-t4165617
Please , be aware that you might brick your device if you decide to experiment with its system.
Hope this helps you.
Hello everyone !
I've got a question about Windows My Phone and Android.
They added last year the possibility to see Samsung apps on Windows, using "My Phone".
I've found this : Use apps from your Android device on your PC (microsoft.com)
Here they say it should work with any Android 11 devices. I still have my OnePlus 6t in Android 10 (it should be updated to 11 ... one day), and I want to know if some of you were able to use this functionnality with their Android 11 device which is NOT A SAMSUNG !??
No one is using it ?
Have you checked the OnePlus 6t forum Section for information...
Hi, I'm not looking only for OnePlus but all smartphones on Android 11 !
Hello everyone, i have the global version of the x3 nfc and today i was happy to see the android 11 update finally appear .
When i got home and connected to wifi i couldnt find the update and now im sad .

Dude you aren't missing out a lot i got the update and installed it I can tell it's really bad battery life isn't as good as on Android 10 + so many lags and glitches here and there, even there's no option in settings for Android 11 bubbles and the bubbles aren't circle they are squares. It's so messed up.
I want to go back to android 10 if someone knows how please let me know.

Not rare, just not popular, Huawei devices are not sold and used everywhere, they are banned in some countries.
If you want to be able to modify devices, buy better quality, more popular devices because those are the devices that receive development from the developers that create what we use here. If you use low end, cheap and unpopular devices, you will have to learn how to build your own custom recovery and custom ROMs because the developers here do not use those kinds of devices or create development for those kinds of devices.
