OMG!! it worked!!! thanks a lot.

About the soldering, I just put a wire connecting the two test points.

Again, thanks for all.
[Android Head-Units] Joewilm:
how long would it take to do "write memory"? It seems not running...should i fill in "File Path"? If so, where would i put it or take it?

did you use the 8227L Hi-Fi folder for the scatter file to recognize device?or from yadi.sk link on your first post... i am confused.
[Android Head-Units] fani:
the two part rar file I have shared includes the new scatter file (MT8127_Android_scatter.txt). it is also in the attachment to the first post.

The scatter file in the original 8227L Hi-Fi folder did not show the three partitions on the device.

it does take a long time to write the 3rd file "USER" because it is about 14GB. in file path you select the files, in begin address you put 0x00, in Region you select the partition on the device with similar name to the file. Hit Write memory, then plug the usb cable in, while shorting the test points together.
[Android Head-Units] Joewilm:
viktor...so, i will select the file path from the two rar file u shared? for example, the Boot 1 from the two rar file that you mentioned?is that correct?
[Android Head-Units] Irimia:
Any ideas to remove the Ford animation that comes with the new rom? I tried to replace it through the configuration menu, but got stuck in the boot :( and had to flash the rom again.
[Android Head-Units] fani:
Maxkir is right. Try a different Boot_1. There are a bunch to chose from. (Link)

the one worked on mine was from "Shuma50"
[Android Head-Units] PamelaGirl:
Okay, thanks

Thank you :)

Hi,

I realized what bricked my HU was selecting "Preloader" in the last ROM : this is a killer. If the scatter file doesn't select it, no need to add.

Also ROMs for 2Go/32Go RAM are not compatible with 1Gb/16 RAM models.

Unfortunately the "Memeory Write" method with the big file Memory Dump Rooted TWRP 20190523 YT9217C HIFI didn't work for me. It seems that SP Flash Tool doesn't recognize the HU at all ! It doesn't react or maybe I need to load another Memory dump file.

I also short-connected the 2 test points with a flat screwdriver head (they are tiny) : The SP flash tool didn't respond..This is supposed to be the ultimate solution or maybe I did something wrong.

---------- Post added at 03:13 PM ---------- Previous post was at 03:05 PM ----------

Another thing I forgot to mention is that the unit and application oppening was a little lagged from factory. It seems like old smartphones of 5-6 years ago.

Have you noticed better responsive (fluid) experience with the new ROMs ?

thanks
[Android Head-Units] fani:
That seems more like a driver issue, Does the device manager loads the new device as you plugin the usb cable?

As a general rule, "you get what you pay for". For 60 euros, its more than decent. Serves the purpose, Navigation, Music, Reverse cam and occasional Youtube. After the recent update to rooted 0523 version, it seems a lot more stable and responsive. no more hangups and lag. And the fast boot loads my agama launcher in less than 2 seconds and music starts within 5.
[Android Head-Units] epilef10:
a mi me pasó igual que a vos, con el destornillador no tuve exito al puentear los puntos de prueba. Lo que si funcionó fué soldar un pequeño cable en el punto de prueba y conectarlo con el cable negro gnd, al conectar el cable usb a la pc se escucha un sonido, cuando comienza a cargar rapidamente desconecto el cable de prueba y conecto gnd a la fuente para encender el hu, ahí comienza a cargar el software. dura 30min la carga.

It happened to me just like you, with the screwdriver I was not successful in bridging the test points. What worked was to solder a small cable at the test point and connect it with the black gnd cable, when you connect the usb cable to the pc you hear a sound, when you start charging quickly disconnect the test cable and connect gnd to the source to turn on the hu, there begins to load the software. The load lasts 30min.

Gracias, al armar el hu tuve un accidente, la ficha de alimentacion estaba muy agarrada y al soltarse pego un tiron y la malla del display se dañó, se cortador dos filamentos que para poder verlos tuve que quitar el display, los soldé con dos cables pequeños y por suerte funciónó.

Ahora no enciende la iluminacion de los botones tactiles del costado, estoy pensando que tal vez conecté al revez la pequeña malla de la plaqueta de los botones, o tambien puede ser que por la nueva actualización me esté faltando configurar algo.

Me da mucha pereza desarmar todo denuevo, tengo de desarma medio auto para quitar el hu.

Thanks, when I mounted the hu I had an accident, the power connection was very tight and when I suddenly released it and there was a tiron and the screen mesh was damaged, two filaments were cut to see them. , solder with two small wires and luckily it worked.

Now it does not turn on the illumination of the touch buttons on the side, I think maybe I connected the small mesh of the button plate badly, or it may also be due to the new update and I have to configure something.

I am too lazy to disassemble everything, I have to disassemble half of the car to remove the hu.

Ya lo arreglé, había conectado mal el cable de los botones.

I fixed it, the buttons cable was wrong.

Ahora tambien funciona el modo sueño, es increible tarda 1 seg en aparecer el launcher y 3 seg en sonar la musica. Tuve que invertir los cables rojo y amarillo.

Now the sleep mode also works, it is amazing, it takes 1 second to appear the launcher and 3 seconds to play the music. I had to invert the red and yellow wires.
[Android Head-Units] epilef10:
A mi me funciono bajar "Firmware via flash tool: Rooted TWRP 20190523 (Link) Thanks Maxkir" luego descomprimir y dentro de esa carpeta cargar MT3367_Android_scatter.txt en flash tool, despues alt + ctrl+ v, despues ir a ventana, elegir write memory, luego cargar desde write memory el archivo user, en begin addres poner 0x0, en region poner emmc_user. luego puentear puntos de prueba, hacer clic en write memory, enchufar el cable usb, luego desconectar el puente de prueba y encender el hu.

esos fueron mis pasos, luego desconecte el usb, apague el hu, encendi el uh y arrancon funcionando correctamente.

It worked for me to download "Firmware via flash tool: TWRP 20190523 rooted (Link) Thanks Maxkir", then unzip and in that folder load MT3367_Android_scatter.txt in the flash tool, then alt + ctrl + v, then go to the window , choose to write memory, then load from the user type the user's file, in startup addres put 0x0, in the region put emmc_user. then skip the test points, click write memory, connect the usb cable, then disconnect the test jumper and turn on the hu.

those were my steps, then disconnect the usb, turn off the hu, turn on the uh and start working properly.
[Android Head-Units] PamelaGirl:
Congrats on getting your device up and running!

I am still having bootup issues ( freeze at boot animation, sometimes goes into recovery, from within recovery I do a reboot and it starts all over again.

First off I cannot get the write memory the large user file.

I get an error message, anyone know who I can resolve that or would there be smaller user files available?

Thanks :confused:

A few things

REMOTE CONTROLS -Anyone get the steering wheel remote controls to work with this head unit, I have not been successful at getting them to work on my honda. Tried to set them in the settings but nothing works then I tried to wire up key 2 (wasn't originally used in the honda harness for this unit. ) key 2 is just another ground but still nothing .

REV CAM -Issues with back up camera and the settings are confusing because of bad translating, anyways the I finally got the backup cam to work with the reverse trigger connected to rev light circuit but now when I shift out of reverse the picture freezes and won't return to the radio/home screen. Not sure if anyone else has had this issue. It would be nice to know what all the settings in menu do.

RADIO -not only is the radio app terrible, the reception isn't great so I got a antenna amplifier thinking I could improve the signal, but that doesn't seem to work, went into the engineering mode and messed with the settings there but i only managed to only make the radio inop until restart lol.

RESET BUTTON FOR FLASHING -Also, not sure if this is valid but I have flashed a boot partition by holding down the reset button after disconnecting usb to pc then plugging in the usb starting the download or memory write, then releasing the reset button. once the button is released I hear my laptop connect to unit and transfer completes successfully

---------- Post added at 01:12 AM ---------- Previous post was at 12:49 AM ----------

Anyone get a hold of the software from the similar Seicane units? They seem to be very similar but have a different user interface, wondering if then chinese units can be flashed with that firmware.
[Android Head-Units] fani:
Check this and see what memory size it says on it?
[Android Head-Units] fani:
You might need a CAN box for your specific car make and model. The head unit keys interface work with Series Resistance based keys. There are some aftermarket solutions, but I'm thinking of building one of my own.

Never encountered any issue there.

No issue here, only the RDS info not shown, otherwise all ok.

Thanks for the tip. I'll try and see if it works on mine.

There are a few UI available. See the 1st post. Also AGAMA and CarWebGuru works great.

Engineering mode access! Pass code requested .

I have used 8888 for factory access.. But for engineering mode it request another code! Please any ideas.?
[Android Head-Units] fani:
try 26959910. Only one I know.
[Android Head-Units] Eri76:
First of all thanks to Victorsaari for his patience with us and epilef10 for the GND tip.

Unfortunately the GND + test points or Short-2 test points gives the same result in my case :

the HU is recognized in Windows Device manager as "Mediatek USB Preloader adapter" for 1-2 seconds then even if I hold the test-point it shows as disconnected.

Maybe what I am doing wrong is that the HU is in my desk not receiving any 12V input.

Should I connect it to 12V source and then short TEST point ? (I have a 12v battery, no need to mount in the car)

I will try with the RESET boutton + USB cable maybe a miracle..

---------- Post added at 02:56 PM ---------- Previous post was at 02:46 PM ----------

If you use the original harness no problem. In My Huyndai santa FE it worked very well (Volume, Mode..everything). Normally KEY 1 is enough.

There is a setting in ENGEENER mode but normally you have nothing to do. You problem seems due to a short somewhere. In the hairness you have a wire labelled "reverse" : this needs to be connected to +12V from your camera.

YES The radio app is horrible : in my case no Station programming ie P1, P2 etc. Also no RDS even if the chip supports RDS.

The radio app is decent with Seicane radios from version 643 and more.

I have used as alternative AGAMA which is very customizable and very nice.
[Android Head-Units] fani:
That is the correct response.

When the Flashtool is started and is ready to receive a connection, at this point when you connect the usb cable, it will start writing and connection will continue.
[Android Head-Units] SamirXda2019:
Engineering mode access! Pass code requested .

it works thanks !

Changes in sleep mode are not visible, what the difference between the 04 SLEEP MODE in this menu of Engineering debug test ?
[Android Head-Units] epilef10:
Lo que hice fue conectar cable amarillo y rojo a +12v. Deje un cable preparado en (-)

Entonces lo que hay que hacer es puntear el punto de prueba con el cable gnd, enchufar el cable usb, luego de escuchar el sonido cuando se ve actividad en la barra de progreso desconectar el cable del punto de prueba y conectar gnd a (-), luego tendría que seguir la carga de datos sin problema.

What I did was connect the yellow and red wire to + 12v. Leave a prepared cable in (-) So, what you should do is touch the test point with the gnd cable, plug in the usb cable, after listening to the sound when you see activity in the progress bar, disconnect the cable from the test point and connect gnd to (-) , then I would have to continue loading data without problem.

95.5% Successful!

Hello All,

I re-flashed the Rooted_TWRP_ YT_9218C_00005_V004_20190523(UI2)

I now have a working WiFi and GPS (its cloudy today so GPS isnt working at strong as before from my workbench).

I posted a new image that says I actually am on Firmware YT9218C_00005_V004.

The Settings windows says:

YT9216C_00005_V004_20190523, could this be due to the Boot1 file?

How do I get my backlight side buttons to work again?

I have tried going into: (You may need to remap side touch buttons in Factory settings -> Touch settings).

Thank you :)
[Android Head-Units] Eri76:
Congrats to all who successfully flashed their head-unit.

I did other tries with and without battery 12V supply. None of the tries succeeded.

Now for some reason, no test points needed : The HU is detected as soon as i lauch Dowload button from SP Flash tool the I get an error:

exemple of same image :

[IMG="error 4032"]http://i.imgbox.com/iIDqNQN5.png[/IMG]

Not sure I want to continue with this HU -- I have spent litterally hours trying to revive it. My wife is mad at me.. :D:eek:
[Android Head-Units] Maxkir:
You need to flash the boot and preloader files first, and then the rest of the firmware files.
[Android Head-Units] PamelaGirl:
Hang in there, your so close!

1. Try switching the ends of the Male to Male USB cable.

2. Close the Flash Tool app and try again.

I truly never wanted to open up this device, this has been the toughest root ever and I was sweating bullets with every test point process. My eye aren't what they used to be and I feel a little wiser but more older since my first root. :angel:
[Android Head-Units] Maxkir:
You have a YT9216C board. It will be so displayed on any firmware.

Setting touch buttons. Use the translator. http://4pda.ru/forum/index.php?showtopic=936535&view=findpost&p=82706353
[Android Head-Units] PamelaGirl:
Maxkir,

Thank you for the link, much appreciated!

As for the YT9216C board, when I first started this journey the head unit said it was a YT9218 board. I was careful not to install any YT9217 firmware due to a radio chip difference, much less YT9216 firmware. This head unit has been funny business since day one when it said I had 2GB DDR instead on 1GB DDR.

When I get my side touch buttons working I will be good to go. I will leave the firmware alone and enjoy the root along with a few must have apps.

I will report back when the touch buttons have been properly remapped.

Thank you kindly :)
[Android Head-Units] fani:
I would try with a different scatter file.

hahaha... been there too my friend, been there too.:D
[Android Head-Units] PamelaGirl:

Hello,

I tried ALL the firmware of the russian page and had lot of "Invalid scatter file" Error messages.

I tried the "Memory dump YT9218C..........." file that is 15Go. Scatter file is OK however now i get a the same Error message (4032) over and over again.

I tried under Linux, I have a dual-boot laptoop and Flashtool for Linux which works well, still I get the 4032 error message under linux so USB drive is not faulty.

I reversed USB male-male sockets : no change.

I tried "Format all + download" : same

After a research I made the DRAM Error message is due 99% of time to a bad firmware but i don't see what is wrong with the firmwares I am trying.

My HU motherborard original specs:

MCU 3.1

Firmware YT9216C...

Build 8227_demo

Image is just for exemple (not from HU) -- just to illustrate the same message I have :

Hello everyone

My English is not good, please forgive me.

I live in Japan. FM in Japan is 76-90 MHz, but my Head Unit is 87-108 MHz, How fix it?

If Flashtool ROM can fix it, can pro information still be retained? Because I want to use the keys on the steering wheel.

In the 2018 firmware, I had option to chose FM radio region. ie, Europe, Asia, America etc.. but in later versions I have not seen it.

Hello All,

Which color wire on the power harness is to be used to remotely power up an Amplifier?

My Kenwood head unit had a blue w/white stripe wire but not seeing anything for this Android head unit.

Thanks :)
[Android Head-Units] fani:
# 7 AMP-C
[Android Head-Units] PamelaGirl:
Thank you kindly friend. :)

I will have a closer look at the harness with the RCA connectors. Either I do not have a #7 wire or I overlooked it in all the excitement of retrofitting its different 1 Din body into a traditional 1 Din slot. (A bit of a tension fit with foam, cough cough)

Thank you :)

How did you connect the headunit to the pc? I also can't boot head unit via its usb1 and usb2 port..
[Android Head-Units] fani:
Read the 1st post.
[Android Head-Units] PamelaGirl:
To connect the head unit to a PC you will need a Male to Male USB cable.

I had two old cables so I cut off the ends not needed and wired on the end needed to make a Male to Male cable. Its really simple, line up the colors

white to white

black to black

red to red

etc
[Android Head-Units] deepszn:
Thank you.. I tried making my own boot animation and the screen is now black but music and touch works but cannot see what is going on..

Will you be able to walk me through how to install firmware or resolve this issue? Thank you..
[Android Head-Units] PamelaGirl:

Secondly has anyone connected the SWC from their vehicle to the unit. I have tried connecting the key 1 to my Honda but with little luck. I have a connects 2 unit with a universal patch lead but still can't figure a way to connect it. The Russian site says use only key1 but where do we connect it to?
[Android Head-Units] PamelaGirl:
Hello Good People,

By now many are aware of the slow transfer rate using Wifi, as a result this can keep you in your vehicle longer when trying to download and install apps like maps etc.

What helps for me is to install VNC Server app onto the head unit. Afterwards you can remote control the head unit from your smartphone or computer. Keeping in mind the head unit will need to be turned on so this means having the key in the ignition or inside the vehicle depending on its model.

With this method I can monitor large apps being installed that can take hours(maps) while still being in the house doing other things.

You modify your Wifi to have a static IP address, and have your VNC Server app to boot at startup.

Cheers :)
