click video link and comment. im not a developer i just listened to the amazon sellers directions and then searched 8227l in google and found a bunch of files, then tested them and now i want to pass the info on.
tp the guys asking if itll work?
i dont know you gotta test it like i did. they worked on my unit. and the files i donloaded came from other style stereos with android.
i just generally think they are all same firmware if it look similar to actual stereo design and ui .

This is what I have.
Android : YT9216b_00002_V004_20190728
8227L
MCU 3.1
MODEL NUMBER 8227L_DEMO

Is this the 8.1go or just 8.1?
Also the android 9.0 has multi screen working?
Can i safely flash my head unit with the firmware listed?

Yes u can ( always do at your own risk like me); but use one of the touch only files. I can't upload pictures yet but i tried to post a screenshot of each firmware look. If its 8227l firmware it should update/flash.

Ok i may try to flash it this few days. Btw the 8.1 is the go ver or just 8.1? What is your recommendation to install 8.1go or 9.0 which is smoother and better?

They both looked very smooth even when running on my stereo. And i have a touch & button stereo it worked flawlessly no lag no glitch.
Only error was for the firmware being for touch screen only

Hello, I would like to know if this type of software has in some menu the option of autosleep to program that it turns off completely and does not remain in standby, in other Android it exists but here I do not see it. Can this Android 9.0 image be flashed even if it now has 8.1? Is it official or is it rooted?
thanks

i have the following head unit in the link attached will android 9 rom support this head unit ? It has touch button such as back,home,volume up/down.
and how does UI2 look like?

Hi guys! I ask for your help, a few days ago I bought an android radio unit on aliexpress, specifically the Junsun brand, with these characteristics:
Model: 8227L
Android version: 8.1.0
Kernel version: 3.18.79 (gcc version 6.3.1 20170404 (Linaro GCC 6.3.2017.05) [email protected] #57
Comp. Number: alps.mp.o1.mp5
2GB Ram
32Gb Rom
7 inch
With Canbus (ford mondeo 2007)
Its my first time with an android radio unit and I am very lost, I would like to know if I can change the firmware or update it, the one that it brings is very limited and does not let me change the brightness of the device or bluetooth functions.
Thank you for support!

Hi guys!
Is it suitable for me?
'Android 9'

Above are 2 android 7.1 & 8.1 example. Below is Android 9 example.
This is for those who have a ( 8227l ) android stereo and are looking for the update file zip. Also the mcu in the about phone menu should begin with ts . I have 5 files from jby tech, they are the Amazon seller of my hizpo android 8.1 stereo unit. From lots of research and emails to the company, i found that these Android stereos come in many brand names but run the same 8227l system. Another company with the same unit is joying but the device name is different along with the entire UI. Please do be sure you have a 8227l unit before proceeding. Other updates for other brands can be found on google and xda forum. I will try to remember to put link for xda forum. Below I have listed 2 groups of files. One is for touch screen only android stereo and the other is for touch screen with volume knob. Please choose according to your type of stereo. And follow the steps below exactly.
1. Download proper zip for your device.
2. Extract the 2 files from within the zip folder.
3. Copy & paste the ( .bin ) & other file on to a blank sd card or usb flash drive. Make sure these are the only 2 files on the sd card or flash drive.
4. With stereo unit powered off insert the sd card or usb flash drive and power on stereo. (Note some units will recognize the file immediately during boot, and others will prompt you after loading main screen. If unit does not recognize it, power off for 40sec and when u power on tap the screen in middle repeatedly with finger until the word "detected" shows in green. If it gives a message in red saying failed please check you have good download copy and have followed the instructions exactly. Will answer questions as i am able to.
All links to files and sites mentioned must be copy pasted. Im not able to attach external link yet.

[Q] 2DIN 'S07' Android 4.4 Using RK3066 - Root?

I recently bought a generic android head unit from Ali Express. It actually works well but I really need to connect it to a CAN bus and write some additional software (background: I want to replace the factory unit in a Nissan Leaf, so it needs to display some vehicle info, show the heater settings and set up the charge timer). I have experience in Android app development and embedded Linux, but I'm still a 'noob' when it comes to Android hacking (root access etc).
I'm pretty sure I will need root access to do what I want. It has 'CAN tx / rx' pins on the back, and I am pretty sure they are wired to one of the serial interfaces internally (I will need an adapter to convert UART to CAN as well). I played around with an app to access the serial ports (i.e. ttyxxx) but I didn't have permission to use many of them - probably the ones I wanted!
I don't want to re-write the existing music player, amp control and radio; I just want to add a new app to carry out my vehicle-specific functions.
I tried the root process given here but it didn't work.
Here are the device details:
Model: S07
MCU Version: MTCB-HA-V2.60
Android Version: 4.4.4_01062015
Kernel Version: 3.0.36+ [email protected] #278
CPU: ARM7 1.6G x 2
CPU/SOC is an RK3066 on a modular board. Pictures attached.
It doesn't have any physical buttons except reset - there are touch sensitive buttons for power, back and volume. It has one SD card slot for map data and no USB on the front (several on the back).
I haven't figured out how to get to the recovery console, or connect it to a PC via USB.
Any suggestions for how to root? Or get to recovery console?
Anyone else with a similar device?
Check out the Huefi thread above. It has everything you need. first page covers root. basically, download the rom you want, put it on the GPS SD card, insert it, and wait for it to ask you to update. Once you do that, it will be rooted. there is no other way to root it if it has 4.4.4. DO NOT INSTALL A MCU file for it unless it is for HA devices. HA is the manufacture of the unit, and if you use an MCU file for a different device, you run the risk of loosing the physical buttons on the unit. This can be repaired by going into recovery and flashing the HA MCU, but that is a lot of extra work
Hi! Thanks for your reply.
I was wary about installing a new image because I don't want to lose the existing radio app and amplifier controls (which are specific to the device rather than the RK3066 SOC module, if I have understood the structure correctly).
* Would a new image replace these apps, or are they actually in the MCU firmware anyway?
* Can I back up my current image first? I looked at some backup tools, but they all needed root access... =Catch 22.
Sorry for noob questions... I'm getting the hang of Linux but still new to messing with Android at a low level. I'd love to play around with a stripped Ubuntu or similar on the device, but I don't want to have to write my own software for the radio parts - at least not yet.
BTW do you know how the bootloader system works? Is it possible to boot from SD card or USB (therefore allowing some other OS to be booted without replacing the onboard image)?

I cant help with the bootloader issues, but I can with some of the others:
-Radio and Amplifier apps are the same on all units, or should I say is compatible across all units. If you were to go into the settings, then factory settings and enter 126 as the password, you can see all the settings you need to make sure your unit functions after upgrading your rom image.
-You can not back up your factory image. its not possible. You can always reach out to your seller and ask them if they will send you a copy of the factory firmware.

SUCCESS! I just downloaded and installed the latest image from Malaysk (I think?) and it looks like it is working well! Radio, music player and amplifier work, and I have root access. Woo! So far so good... Thanks!

Hi, I also didn't know the screen resolution, and it is not mentioned on the "About" screen.
In the settings menus, I found some options for recording a video of the display (I don't know why!) and the maximum resolution there was 1024 x 600. I figured that you wouldn't bother to record at higher res than the screen had, so the resolution must be 1024x600. This seemed to work!
My stereo has absolutely NO branding on it anywhere so I don't know whether it's a clone of Huifei or something else, but it worked with the "Malaysk" firmware, which I downloaded from the Huifie file repository (linked from here), under firmware->Malaysk ROM->Malaysk DualCore RK3066).
I picked the bottom one (12th Jun 15, 1024x600 with different launcher).

I just installed the same unit. Only complaints are streaming music via Bluetooth only works if you open up the Bluetooth app (probably because android doesn't act as a Bluetooth sink). The other issue is, I cannot seem to change the brightness of the screen...its a touch too dim for daylight (I have a convertible) and a bit too bright for nighttime.
Glad to see you got a custom rom working.
Hey jcolebaker, do you think you could post what the LCD model number is? Is it a Hannstar HSD070IFW1-A?

Sorry not sure what the LCD is - I don't want to pull it apart. It has a board on the back which has the following on it:

That's soldered to another board that says:

Update question
Do I burn the update.img file to the sd card or do I simply copy it? And does it have to be my gps sd card or can it be a spare blank one?

Doesn't appear to be an img file in the context of "burn it" so I think that answers that question (just copy it) The head unit doesn't seem to do anything when I drop it in though (either with it on when I insert it or with it already inserted during a reset). Any thoughts?

The file should be "update.zip". I used a new SD card - try formatting one with FAT32.
You just copy it to the card and insert it - I think the stock Android image automatically checks for update files that look like this, and loads them. This process worked OK for me - if not then hopefully someone here knows more about the update process than me.
HI !
I also try to root my 2din android without success... I have the same as your and I fail to get recovery and the android can't detect the update.img (or update.zip)
I have tried many tips, my sd card is in fat32, well detected by android ...
Do you have the tip to access to the recovery ?
Thanks

I think the file is "update.img" not "update.zip". Anyway I have not figured out how to get to the boot loader on mine, and I never got any recovery console. Sorry I am too much of a beginner myself to suggest anything.

Instead of flashing a new image, go to the factory settings and type in *#hct#root#
This should give you root, no need to flash a new image

Bonjour.
If you would like more than root and you're still having trouble getting into recovery with your Hot Audio RK3066 1024x600 2 DIN Head Unit, the steps below have worked for me when the system does not automatically detect the mcu or update.img.
*** Prior to flashing any OEM or Custom ROM firmware, I recommend using a backup app like Titanium to save all your existing apps and data to your external micro sd card or usb memory stick.
1) Install Quick Boot or a similar apk from the play store.
2) Attach a wireless usb or usb keyboard and confirm it is working as intended. I use a Lenovo N5902 but most usb or wireless usb keyboards should work for this task.
3) Make sure you have the update and or mcu image file on your gps micro sd card or an attached usb memory stick (not the zip file).
4) Open Quick Boot, select recovery, and the system will shut down and boot into recovery.
5) Use your usb keyboard to scroll or arrow down to the update option with correct img file location, then press enter to execute the mcu or android firmware update or both.
6) After you update the android firmware, it is highly recommended that you go into the Settings > Backup & Reset, and select reset to factory and check the box to delete all data from the internal sd card. This reset to factory and internal sd card wipe should give your updated android system a clean start and help avoid system issues due to left over data from the previous firmware.
7) Delete the mcu and or update image from your external micro sd card. Done.
Hope this helps...
Best to all,

So.if I understood correctly....
You have updated your unit (not joying) with the joying Android 6 firmware. And now you have issues on boot as it appears a message that "ui and mcu dont match"
Do your unit boot?

You have to enter into recovery menu to downgrade to your seller Android ROm.
Check on forums how to get into recovery.
Some guy wrote about plugging a keyboard and some key combination resulted into recovery menu.
There you can force to upload a new software (this time use the one supplied by your seller)

So.if I understood correctly....
You have updated your unit (not joying) with the joying Android 6 firmware. And now you have issues on boot as it appears a message that "ui and mcu dont match"
Do your unit boot?

The boot is normal. I asked the seller, but I do not know how to get into recovery mode.
I still do not have enough information.

That is *NOT* the product you own. The specifications on that product indicate "RK3188 Cortex A9 Quad Core 1.6GHz CPU"
Yours is clearly an Intel/Sofia x86 CPU, which is so different that if you tried to install intel/sofia firmware on the rk3188 unit, it definitely would not boot.
Now there is something I find extremely interesting about your unit;
the MCU string indicates that it is an FYT5009 unit, just like the Joying, but with a manufacturer of "KEQ". Up until now, we have only seen Joying units with the FYT5009. If you can figure out how to load the Joying MCU firmware on there, then it just might work. This might be accomplished by just re-running the update process. There is a file that you would have to rename though -- 5009_20.zip has to be renamed to 5009_60.zip.
But beware; there is also the possibility that the Joying MCU firmware could brick the thing. I doubt it though, it is likely that yours is built from the same schematics.

The product is SOFIA chipset is right. It is written by the seller differently from the actual one.
I will attach an image link before the update.

As doitright6 said, it is not a joying product, but it could be updated in the same way.
I will attach the updated JOYING 6.0 firmware and my unit's 5.1.1 genuine firmware.
Please let me know how to fix it.

Thanks.
My Android unit is not a joying product. However, I am using the same CPU chipset (intel sofia).
Joying has been updated to the new version of Android 6.0, so it Like that string "UI and mcu does not match". I have genuine firmware but I can not downgrade it.
Help me eliminate red letters and yellow background in my product.

I can't find fyt.prop file and I had rooted. I have android 10 , is there another solution?
In the same boat. Found the file in CX file explorer (yes, I'm rooted and CX is in root mode), but it won't save my changes ("Cannot save the file".).
Is there a known way to edit and save the fyt.prop file?
At least I only have $20 and a few evenings invested (I found my unit brand new at a thrift store). Been one of my better behaved ones but I got greedy on updates. Also, I flashed the wrong file because I misread my MCU version number, and what *should* have been the right file loops when I try to flash it (reboots after the "CUSTOMER ID" text of the MCU update, have to reset to end the loop)... Whoops!

Help identify unit, manufacturer code ZQ?

I bought one of these Chinese Android boxes that integrate with your existing head unit and I'm trying to find any information about it, and which forum I should be posting questions to. FWIW I have a VW Touareg with an RNS850 system that is basically the same thing as the Audi MMI 3g+ system, but with a touch screen.
Here is some model and version info:
Model: ZQ8002
MCU: TUREG-ZQAND-1.1
APP: MTK-8002_C37_GA1_DZSJ_DaZhong_EN_2019-05-27
Android: 6.0
CPU: 4 core 32-bit CPU Coetex-A7 @1.3G
RAM: 2GB
Flash: 16GB
Baseband Version: MOLY.WR8.W1449.MD.WG.MP.V61.P3
Kernel: 3.18.19 [email protected] #2
Hostname: fise8321_tb_m (seen via ADB shell)
It has a "Factory Settings" menu similar to other Android head units I've seen mentioned here. That presents a numeric keypad. I figured out a few codes for it:
0000: Bunch of debugging toggles, also toggle for ZLink CarPlay
5555: Just says "ok" when you enter it. I think this turns on ADB over TCP. I was able to ADB to it after this, but I had also use a terminal emulator to enable it.
9999: Single item to allow installation of "APP", which I assume is the firmware?
The box on Amazon: https://www.amazon.com/gp/product/B07PJGLD41/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Main issues I'm trying to solve right now is that my skip track buttons on my steering wheel aren't doing anything, even though I can see the CAN bus events in the logs when I press the buttons. I'm hoping there's a Factory Setting code I haven't found that might let me change the CAN Bus settings. It has carCanBus and FactorySettings apks that I was able to decompile, but didn't find anything useful.

I don't know how is it possible to exctract the MCU file (.bin) by the interface. I could try to find online anything to do it. i try to find softwars and so on, if i'will try i tell you something. I send many mails to producer of the unit, but everytime i do it, he tell me to waiting for response of the engineering department......and i wait. My MCU was TUREG-ZQAND-1.3 but i think your version 1.1 coluld going rigt for mine.

MCU version of Erisin ES6292B 9" PX6???

I received an Erisin ES6292B 9" PX6 for Mercedes Benz.
I don't know why but for some reason I was sure it was a MTCD/E version so without prior checking, I immediately went for the upgrade to Hal9K MOD.
The upgrade finished and the unit rebooted. I am not sure if I saw the boot logo (I think not) but as if this was not enough, during first boot, someone in the workshop cut the power to the car and the unit was bricked!
I wrote to Erisin and they sent me the Stock image to try to apply from recovery. However it is impossible to enter recovery with any way I tried. As long as I hold the reset button the unit is dead. When I release it the backlit starts but the screen remains black even after 10 minutes. No recovery, not even boot logo! It seems the MCU firmware is corrupted.
At the moment I have an ST-LINK/V2 programmer in my hands to go for unbricking with Wadzio method but STILL NO ANSWER FROM ERISIN IF MY UNIT IS MTCD/E or different.
Anyone knows?
Also, anyone knows a direct link to download recovery.bin for my unit?
What are the names of the files that were being applied for upgrade? Are you able to share these - assume you had two files, one MCU and the other android.
Also the stock image ersin supplied.
Note the wadzio Unbrick is for MCU unbricking, are you sure that the MCU is bricked? I.e. you are sure you were upgrading the MCU, because from your description, sounds like you were upgrading the SOM/Android.
Details are everything.

When there is no boot logo, I guess it is the MCU. Correct?

The zip doesn't contain an MCU, and is an android OTA zip, therefore if your power outage occurred while applying this file, the SOM emmc/nand is probably corrupt, and you might not be able to enter recovery.
I've had a number of SOMs sent to me exhibiting the same symptom, so not uncommon.
If unable to SDCard boot, SOM recovery via OTG is the likely path to recovery. Refer my threads/signature.

I still have not managed to find out if my MCU version is MTCD/E or other. Still waiting for Erisin's response. They requested a video with symptoms which I already sent.
Supposedly my MCU's version is an STM32 and I tried to install Hal9k's ROM (specific for MTCD/E) wouldn't that corrupt the MCU? To my thinking, this is the most probable scenario.

The files you list are not MCU updates.
Its trivial to determine if you have an MTCD MCU using Wadzio's decryption tool, however & once again, the MCU is separate to Android. You cannot flash the "wrong" platform MCU (ie. MTCD vs STM MCU) in recovery.
Once again; the files you list are ANDROID and not MCU. Unless you havent described what you were doing to "upgrade" the unit, which lead to corruption; the SOM is bricked and not MCU.
Again, for clarity, MCU and ANDROID are not the same. They are separate images and cannot be flashed together.

Kind of getting there. Ha ha, my knowledge is very epidermic! Tomorrow I ll try the SOM recovery via OTG as you suggested and report. Thanks for your time
Just a (silly?) question: Could we say MCU is equivalent to bios on a PC and Android is the equivalent to PC OS? If the MCU (=bios) is still untouched, even with Android (=PC OS) corrupted, why is it impossible to boot from SD or simply access recovery?

The MCU is more like say an auxillary fan and button controller, connected to a serial port, but still controlling the power supply to the computer.
Why impossible to boot or access recovery - corrupt emmc/nand.
Your unit doesnt look like an MTCD/E device.
Unfortunately hardware used in my PX6 implementation is quite different from what shown in SOM recovery over OTG page. I don't have the tools needed to uncover the SOM (75W soldering etc). Judging from the bottom, it seems the SOM is embedded on the mainboard and there may not be any pins accessible. However, rk3399 supports what is called MaskRom mode (a relevant link translated from Chinese) allowing programming of the SOM with the use of a male to male usb cable. But this would be possible only if we access the interior and find that the test points to bridge exist. My last resort if nothing else is possible.
Another issue I am facing is that my firmware is not in update.img format but comes in .zip split in several files. I think I need to repack it in .img format in order to be able to program my unit with existing tools and I don't know how
Just a last (stupid?) question. Accessing the MCU via ST-LINK/V2 programmer is possible. If we new the starting memory address of the SOM firmware or the various parts, would it be possible to flash from there?

It is an STM32 eventually. I managed to unbrick it but the MCU was changed. Both firmware and config. I am stuck with an 800X480 desktop on a 1024X600 display.
Can you export your MCU.cfg file and send it to me please? I think you need to go to settings/about then toggle between Kernel Version and OS Version 6 times in total to enter hidden menu. If a password is asked, try 666666 or 123456. From there you can go down and select export config.
Thanks in advance!

Need Android 10 Model: px5 MTCU_HT Custom Firmware

Hey there
My Head Unit is no longer saving the last used memory and the radio just stopped working this week.
I am looking for custom firmware to try and hopefully get my unit working properly.
I have searched online and with not a lot of luck. I found someone with custom Firmware on Youtube
but I have used his firmware on another unit a few years back and you can't turn off the auto screen saver option
so I would rather not use his firmware again.
Any Help?
My specs:
Pumpkin Android Radio
Model: px5 (1024 x 600)
Android Version: 10
Last security Update: 5. May 2020
Build NUmber: rk3368-userdebig 10
Kernel-Version: 4.19.111
MCU-Version: MTCU_HT_V3.71_1 Dec 19 2020
CPU: Octa-core Cortex-A53 @ 1.5G
Memory: 3937 MB
I hope someone can help
Thank you in advance.
The file I uploaded is the firmware update the seller sent to me.
Seller instructions:
Update methods:
Download the link on your computer--Don’t unzip the file update.zip. Copy this file " update.zip" to the USB root directory. Connect the USB stick to the USB port of the radio. If the radio detects the update immediately and wants to install it, click on Cancel.
Then open Settings> System> System Updates> tick the box > click Install.
I installed it all Okay. Still have the same problems.
I also found this firmware
Hal9k_Mod_5.0_MTCx_HCTx_PX5_eng.rar
From
And it also installed Okay. Looks very different (I don't really like it that much, far too bright) however I still have the same problems.
I am starting to think it's a hardware problem.
I will post back after trying something else.

Then open Settings> System> System Updates> tick the box > click Install.
I installed it all Okay. Still have the same problems.
I also found this firmware
Hal9k_Mod_5.0_MTCx_HCTx_PX5_eng.rar
From
And it also installed Okay. Looks very different (I don't really like it that much, far too bright) however I still have the same problems.
I am starting to think it's a hardware problem.
I will post back after trying something else.

You even did not tell anything about your issues you are facing. What do you mean with:
My Head Unit is no longer saving the last used memory and the radio just stopped working this week.

So really think about that and communicate correctly.
The same would be if you call your workshop that your car does something wrong and don´t tell them what happens.
Would you get any instructions? I think not.
So tell us the issues and then thee might be some answer possible.
@localos : I think just pushing links to any firmware version without having a bug report does not make any sense.
