I'm about to do the same with Arduino, i prepared the sketch and the circuit diagram, but it shouldn't be a delay timer, it should be a timed pulse to keep the inside capacitor charged, and not to turn on the screen (pulse in milli seconds) each 30 or less seconds, i'll share the full solution with diagrams once i finish it.

Hi I am new on this forum.

I purchased lately from a Chinese reseller a head-unit SEICANE H543 which at my big suprise doesn't not support RADIO RDS functionality.

In Europe even radios 20 years old support RDS...

System information :

1Gb RAM / 16GB ROM

Android YT9216C_AHD_00005_V004_20190522_HIFI

MCU HW8227L-3.3-SWO-3.1 (in fact it is AC8227L)

I have accessed the Factory settings and under some menu I found the radio information which looks that supports name of the station as text : I saw the name of the station written in text. Sorry I can't upload an image for the moment.

Radio shown is "'CHIP ID 6625".

Seller says "Sorry this unit doesn't support RDS". I think they don't want to deal with upgrades even if the hardware supports RDS.

My question is how to upgrade this Radio.apk which is very rudimentary : No station saving, No RDS.

Thanks for your help.

Hi,

Me and [MENTION=9936717]viktorsaari[/MENTION] have the same problem, we are looking for bettere radio app, trying them from other HU similar to ours.

No luck so far.

Btw you need root, becouse it's the only way to replace FMradio.apk in /system/priv-app.
[Android Head-Units] Eri76:
ROOT

PS.

I have another question: has someone already root-ed the HU type YT9216-9217-9218 ?

"I mean no one has thought to develop a tuner application that uses Phone radio chip and doesn't need internet..?! It is crazy how people depend on internet connection these days "

The main problem is: Radio app are made specifically for the chip and framework used in the HU, becouse there is no pre made android layer for FM radio

Rooted FW is in the 1st post,

I'm currently using it, without any issue. Also viktorsaari has installed it.

You need to flash using SP flash Tools
[Android Head-Units] fani:
Yes, and it has proven a lot more stable version. :good:

I screwed up again

Tratando de actualizar a la vercion yt9217c con flash tool, acabo de bloquear mi hu, ahora no detecta el cable usb al conectarlo, la pantalla enciende de color blanco parpadeante al conectar el cable, pero ya no se escucha el sonido de conexion, al accionar la llave de contacto flash tool no hace nada, antes empezaba a cargar.

Lo que hice fue usar el MT8127_Android_scatter que esta en a primer pagina, dento de la carpeta de Rooted_TWRP_ YT_9218C_00005_V004_20190523(UI2)

Seleccioné boot.img y Android solamente. Luego resetie desde el agujero en vez de apagar desde la llave como lo hacia siempre.

No se bien cual fué el causante, estoy un poco asustado. solo me queda desarmar y probar sin corriente puentendo los puntos de prueba, si tienen algun consejo estaré agradecido.. gracias.

Trying to update to the version y9217c with flash tool, I just blocked my hu, now it does not detect the usb cable when connecting it, the screen turns on a blinking white color when connecting the cable, but the connection sound is no longer heard, when operated The flash tool contact key does nothing, before it started charging.

What I did was use the MT8127_Android_scatter that is on the first page, in the Rooted_TWRP_ folder YT_9218C_00005_V004_20190523 (UI2)

I selected boot.img and Android only. Then reset from the hole instead of turning off from the key as usual.

I don't know which was the cause of the blockage, I'm a little scared. I only have to disassemble and test without power bypassing the test points, if you have any advice I will be grateful. Thank you.

Is my unit 1GB or 2GB DDR?

Hello Good People,

Is my unit 1GB or 2GB DDR?
[Android Head-Units] fani:
did you check with cpuz? or similar app?

There are a few of those "fake 2gb" devices as well out there.
[Android Head-Units] PamelaGirl:
Tricky Tricky!

Looks like I have 1GB DDR and not 2GB.

Geez, it even also says I am rooted but I aint!

So I should be safe to use the file you provided in the link?

Thanks :)
[Android Head-Units] Eri76:
In my opinion it is obviously 1 GB DDR . It says so on every screen you show :)

Also another indicator is the price :

1Go RAM => 100-120 US$

2Go RAM => 200 US $ or more.
[Android Head-Units] PamelaGirl:
Right on Eri76!

This is tricky business getting the correct specs vs what you bought. Now its time to dig in and root this once and for all.

Thanks :)
[Android Head-Units] fani:
That qualifies for a full refund.
[Android Head-Units] Eri76:
Very easy : download a Root check app on Google Playstore so you will know.

There are many ex https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&hl=en

However to have your HU root-ed you need a pre-rooted ROM installed.

I have checked many ways to root it with other methods but I didn't succeed.
[Android Head-Units] PamelaGirl:
I have contacted the seller and awaiting a response.

I may be able to get access to a friends computer running Windows 10.

I have experience with using Odin but not this Flashtool. If your time permits would you please walk me through the exact steps needed to perform root using Flashtool?

My Male to Male USB cable is ready to go.

Super Thanks :D

This didn't work for me on 2 different USB sticks. Zipped or not zipped.

When I go to the Menu / Setup / car settings / system info : Android upgrade is grey (not activated).

I am waiting the MALE/MALE USB cable to try with SP Flash tool. I tried to install MTD drivers on my Laptop Windows 10 and they failed .
[Android Head-Units] shiner88:
For MTK driver i've used this on Win10 without any issue https://mtkusballdriver.com/download/mtk-usb-v1-0-8
[Android Head-Units] fani:
It depends on what file you are using to upgrade. I have not yet come across YT9216C_AHD upgrade zip.

But I'm guessing it would probably be named similar to this:

"xyauto_ui2_9218C_full_8227L_demo-ota-201900522_HIFI .zip"

From your previous post, looks like you already have the latest firmware and mcu.
[Android Head-Units] PamelaGirl:
Hello All,

I attempted to use flash tool to root my device and for the last hour my head unit stays on the bootup screen though not frozen.

I flashed Rooted_TWRP_ YT_9218C_00005_V004_20190523(UI2).rar

MT8127_Android_scatter continued to fail

MT3367_Android_scatter went through the transfer process and gave the "green download ok" check image.

I disconnected the USB cable and powered up the head unit. It seems to start up as normal but is stuck on the bootup animation.

Yikes! What should I do?

I did not check the reloader.

Sadly I unplugged the head unit and plugged in back in and now no boot up screen, just a faint backlight, and flashtools doesn’t recognize a USB connection :(

[Android Head-Units] fani:
Flash the Boot_1 dump as well, and try, its in same folder.
[Android Head-Units] Eri76:
I dont' even have access to the device, let alone SP flash tool.

1- Installed MTK driver with Windows unsigned drivers safe mode.

2- Device put in "USB debug mode : ON".

3 - Tried to connect with my Linux Laptop and USB drivers for Linux : no result.

I installed ALL-MTK-Drives manually but Windows says "Windows can't start this device - Error 10"

Backlight screen with my USB access :(

First off I want to give a huge THANK YOU to everyone on the thread that has responded to my post.

I have held my own by rooting and installing custom ROMs on all my 15+ Android devices in the past, and never bricked on!

With that being said I need some help because now my device boots to a backlight screen and flashtools doesnt recognize its USB connection.

Where do I go from here?

A working unit is better than a non working unit, a rooted unit is better than a non rooted unit.

Viktorsaari, I am looking in that folder and do not see a Boot_1.

What is the next step to get the unit to bootup and return access to the USB port?

Super Thanks
[Android Head-Units] fani:
Sorry, its ROM_1 BOOT1 4mb, its the first partition, which holds the preloader.

I think the only way is the test point method. (picture is in first post)

Anyone have installed Google Assistant? I can't use it due to unsupported device :(
[Android Head-Units] Eri76:
Thanks Victorsaari.

For some reason it didn't work when installed in my car even unit was off -- I removed completely the HU, took it to my desk and connected with USB. Now it works.

The problem is that the ROM in the first page named "XYAUTOUPG-701+701Ui1 (1)" seems quite old version YT9216B and all my buttons don't work anymore.

Also most of ROMS i found in russian board, when downloaded with SP FLASH says "Scatter file invalid" !

Can you help me with process to map the touch boutons ? I did enter the factory code 8888 and was in the menu but I don't understant how to map the buttons with HU.

Thanks.

Same problem that Pamela Girl: I tried to install another ROM from Russian forum YT9218C flashed perfect, then when I turned on the unit the screen stays blank : No update progress.

Now I wanted to turn back to same ROM but SP FLASH TOOL deosn't recognize the HU anymore :crying:

I tried to open the motherboard to find the test points but the screws are soooo tight that i almost broked 2 screwdrivers !!!

HELP.

I just want to bring it back to what it was an hopefully resell it if I can. It is very very low quality material

[Android Head-Units] PamelaGirl:
Viktorsaari, your becoming a legend / hero in these parts :)

Thank you kindly for the response and the upload. So it looks like I need to crack this unit open. If I can a head gasket job on a car than this should be easy enough. I just need to ask a few more questions to settle my nerves.

1.Open unit and connect a short out the two test points with a single wire? Does this mean I need to solder the wire or can I hold a wire to the test point?

2. At this point I would start FlashTools?

Exactly what files should I be flashing at this point?

In the Flashtool menu should I be in: Download only or Firmware Upgrade or Format All with Upgrade?

My device is not working like yours but with your help I am hopeful I can get it working.

Super Thank you :)
[Android Head-Units] fani:
Follow the Memory Dump Procedure, in first post, but only write the boot_1 at EMMC_BOOT_1

Only hold the short while connecting the usb cable and wait until the write process starts. Pencil lead works too. No need to solder.

Although I have permanently soldered thin wire with a push button at the end, so I don't have to open it again, while I test different roms :silly:

After jumping the test point I was able to install the ROM_1 BOOT1.

At this time I disconnected the USB cable and powered up the unit. It would not take me to the desktop, instead it would hang during the bootup animation and would take me into TWRP Recovery.

[Android Head-Units] PamelaGirl:
Hello again my friend,

Was doing the Memory Dump from the Memory Dump Rooted TWRP 20190523 YT9217C HIFI file and getting the flashing backlight at startup.

Did I download the wrong Memory Dump file for my YT9218 unit?

I will download and try the Memory Dump 20181222 which is a much larger file.

Should I be doing a Memory Dump of A or B

A:

ROM_BOOT1

Boot2

User?

B:

Boot1

Boot2

User

The User Memory Dump is over 15gb?

After a successful Memory Dump, should I flash the firmware YT_9218C_00005_V004_20190523(UI2) but not the preloader?

How long should the first boot take?

I need to reference this as a means of troubleshooting.

Thank you :)
[Android Head-Units] fani:
Hi, I'm glad it worked, and your device is now ok. :highfive:
[Android Head-Units] Maxkir:
Apparently boot1 does not fit. Need to flash another.

Choose according to the firmware version that you had after the purchase.

Do you have a screenshot where the version of the firmware that was installed from the store is written?
[Android Head-Units] fani:
it depends, what was the original rom version on your device?

start with just the "user" and experiment.

Out of 15gb, the firmware part is under 3gb, the rest is empty space,

If you want to try, read through the scatter file for locations, and use a hex editor to crop out just the firmware.

Try the regular ota upgrade via usb drive after that.
