I am trying to figure out how to root this specific model. I have read abunch in the forums but am still not certain which firmware to install.
Also, am I suppose to make a backup with adb? How do I do a full backup that would be flashable in case I brick it?
Any help sure would be appreciated. I have the 2gb ram 16gb flash version (not sure if it is really 2gb/16gb, does anyone know how to check?) and the download links I have found are all for the 1gb version. This unit also has android 10.1 but I know that's not the case, but this unit just had to many different things than other units mentioned in these forums. I just don't want to risk it by blindly flashing something that is going to ruin my head unit.

I have this head unit that came installed in a truck I purchased;
http://www.amazon.com/gp/product/B00WG1PKJC?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
It runs 4.2.2 and looks to be new. My question would be, Is there anything I can do with it? It runs pretty decent and supports most, if not all of the apps I use. I would like to update it to a custom ROM but it's unclear if I can or not.
Thanks ahead of time!

Yes, this is correct. Completely read the first post, paying attention to upgrading to a pre-rooted 4.4 ROM and which MCU to install.
4.3.14-7-10-650201-150527
This is what my system is reporting what version MCU it has. How do I identify what I need to upgrade?
Anybody? All I'm looking for is if I can install 4.4.4.
Thank you.
I'm still confused on which unit this is. Any other way to find out other than mcu?
I really would like to upgrade this thing. I HATE the hard coded buttons at the bottom of the screen. They take up nearly half of it.
The upgrade method should be the same as with the rest most likely (copy the ROM to the root of an SD card, put it in the GPS slot, get into recovery and it should prompt you to upgrade). You should be able to flash any ROM that's made for your CPU, regardless of which MCU you have/need. I haven't flashed the MCU on mine since I see no reason to do it (if it ain't broke...) but the ROM and MCU can be flashed independently so no need to worry about the other if only one is a problem.
About the launcher, that's just an APK so you should be able to install a new launcher even without flashing a new ROM.
Having a hard time finding the latest or best Update.img for joying 10.1 head unit
Its still rk3188
Ive followed some links but the update. Img i tried failed I need link to the best latest rom for the 10.1 model Not sure if screen size is relevant for type of rom
Can someone please link me ?
Also should i out the .img on the nand flash or usb drive
What latest ROM? The official? Look on joying site.
Also, there are two different versions of 10.1. Both have different ROM requirements.
Is there a reason you need a new rom? That's a pretty recent product.

Yes there's a lot of necessary tweaks changes that make the unit desire able.
Mine is the 5.1.1 there is no rom for it
And I also just bricked it cause someone linked me to a 4.4.4 model rom..
Now I don't know how to try restore it
Cant get into recovery mode at all now
Where would I download the official 5.1.1 firmware through joying themselves?

Sorry to hear you might have bricked it. Yes, at the moment there doesn't appear to be any community ROM available for these units. You may have seen other other threads on the same topic.
You will most definitely want to contact Joying support about any possibility of unbricking.

FLASHING THE WRONG ROM WILL BRICK YOUR DEVICE AND VOID YOUR WARRANTY WITH JOYING!!!
If you have a 4.4.4 (MTCB) Head unit you can get the latest Joying ROM on carjoying website or you can use Malaysk ROM.
If you have the Lollipop Android 5 (MTCD) Head unit you need to contact your seller for the ROM and MCU.
I have had few head units already which do not even go into recovery because of wrong ROM/MCU was flashed.
There is no Malaysk ROM for android 5 MTCD Head unit now.
You can donate to support his work so we can send him a MTCD head unit to work on and develop Android 5 ROM
Hi,
This might sound a weird question but can anyone clarify the following
I got a unit which has MTCE_CZ_V3.17_2 MCU (Wondefoo)
Can I for example flash it with MTCE_MX_V3.41 with HCT4_PX5_9.0_ota(20191125) MX/WITSON Firmware?
Or the best is to remain with original MCU?
Can I stay with original MCU and flash with other brand Firmware like HCT4_PX5_9.0_ota(20191125) MX/WITSON?
In short: can I cross upgrade with "X" MCU and "Y" Firmware or the MCU and Firmware has to be always the same "X" version?
What is the best option / combo? The MCU should always remain the original and can upgrade with other brand firmware or can change both?
Thanks
You better ask this in the MTCD/E areas of this forum:
https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development
https://forum.xda-developers.com/android-auto/mtcd-android-head-units-general
Edit: which you alread did.
Don't cross-post. It is confusing and annoying. I understand that you try to get as much info as possible, but this is not the way.
And IF you cross-post, please refer both threads to one another. That prevents people from spending precious time giving the same answer as someone else already did.
So I bought this head unit and i am looking to root it. I'm accustomed to XDA and rooting and I also found the russian forum that disscusses these head units but I'm lost. It seems mine is newer(?) or more up to date than im seeing. It says android 10.1(it seems to be really 9) and is API 27.
Things i see seem to be giving root for my device but downgrading it. Is there any assistance I can receive on this? Attached some screenshots.

Okay so having the newer Android shouldn't be a problem as your unit type and MCU are right for modding.
I've successfully modded a similar unit only a couple of weeks back. Backup your current ROM by exporting the full memory dump, just in case of brick.
You start with installing TWRP recovery. Normally only version 3.0.2 will work. If not, try newer then older versions. One of them will stick.
After TWRP it's an easy ride. Install SuperSU v2.79 and if it doesn't work, try newer then older versions.
Now you can install Viper4Android. I suggest you stick to version 2.5.0.
Now just configure everything you need.
Ok thanks for the reply. I did some searching today on the forum after reading your post but all I see is flashing a whole new rom.
Is there a guide to just install TWRP to my current stock rom(I actually like it) and then the usual SuperSU to obtain root priveleges?

I just posted this this guide that provides custom firmware and lots of improvements to YT9216BJ, that includes TWRP, SuperSU and much much more. You can of course stick with the stock firmware but there is an option of making your unit much more appealing
Hi guys as the title says. I'm looking some advice of any compatible roms available for my android headunit. Its currently running android 10 however the stock firmware isn't great and I would like to try something different for it. I believe there are many different 8227l roms and not all compatible with all devices which is whay worries me. I've searched and searched but cannot find anything that i believe to be compatible, there are so many different types. Mcu etc. Etc. I don't want to flash something and brick my device. I've taken some photos of the system I hope this helps and thanks in advance for any assistance you can provide
EDIT 1:
When I asked the seller if there were any updates he says I was in the latest update. He send me a copy of the firmware and its named
8227L_8UI01-国外10_v2_20191115
If this helps
