[Android Head-Units] pajurpl:
In the end I was able to upload

After a few hours of torment, my beloved radio managed to put me on my feet.

I uploaded with preloader selected because I had a brick (black screen) radio and it didn't turn on. If your radio has no brick, uncheck the preloader when downloading the firmware.

No power supply needed for uploading, just usb (4pin)

Below full firmware with preloader and scatter full firmware package YT9213A_00009_V001_20191126 ready to be uploaded by SP Flash Tool.

Below the upload instructions are recorded quickly.

I saw that someone above was also looking for a preloader for this model should definitely be useful.

Anyone able to get maps go and navigation for go working on their radio? They both installed fine.

Issue is there is no navigation button.

Good lightweight google maps for devices with 1gb.

[Android Head-Units] pajurpl:
I just tested it and it looks like this app

https://play.google.com/store/apps/details?id=com.google.android.apps.navlite

from this link is an add-on, a module for this main google map application, therefore there is no icon although in the application-settings is visible

I don't know if that was the case.

Thanks for testing. Yes, that app should enable the navigation button. From reading its an issue with landscape devices. Need portrait, then go back to landscape. I tried the rotation app but couldn't enable portrait. Also enabled all the permissions in settings.
[Android Head-Units] fani:
I did just that, and the yes the "mclaught" app unpacks to Sources and Resources. But when I unpack my original app, it only unpacks to Resources folder.

The app from mclaught does not allow for custom background image. And honestly, I like the style of my previous app. I had made custom adjustments in it. Therefore I made the necessary adjustments for the Station name display in my own app. but can't modify the hifi issue because it doesn't unpack the Sources. :rolleyes:

YT8216B and STM32 chipset

Hello all,

ive bought the unit and Ive decided for the following:

- radio app with RDS

- change the microphone due to bad outcoming call quality

- to recieve the full access and ROOT

- add the active antenna adapter to improve radio reception

I no in the TRAP with the first point:

I have the image, but Im not able to connect to the device:

1) SP flashtool and USB

- all MTK drivers installed correctly under WIN0

- new A-A cabel

- tested with POWER OFF and POWER ON, all USB options checked in the device - NO PROGRESS (seems like the USB is power supply only)

2) ADG and WIFI

- tested all possible hints how to connect

adb kill-server, adb tcpip 5555, adb connect....

PING is working, but with adb connect the device will refuse the connection with code 10061

3) SD card

visible in the device, possible play the music

any zip as update is ommited during the device start

4) SP flash tool and short TEST POINTs

What was the function of the pins in the first post?

Any Idea which pins can I try?

Ive found in the FACTORY SETTINGS the menu UPDATE, unfortunatelly all options are in chinesse? (Picture 3)

Thank You for any hnts, proposal etc. :)

Hello :D

sorry if I ask about this old question.

I need an advice.

I would like to know if after soldering the two wires of the new external microphone I have to desolder or unplug the old microphone too?

Or can I leave it connected?

Is it a problem if I leave them both connected?

Thanks for any response. :good:
[Android Head-Units] wooldogsinc:
I recommend taking it off. As you will reduce the quality. Can you send me a close up photo of your work?

Looking at doing this mod too.
[Android Head-Units] emta43:
Sure, disconnect the old one. At least one pin. Its possible without the knob demounting.
[Android Head-Units] rockrider81:
Thanks everyone for the quick answers. :)

I forgot to say that my device does not have the knob but the classic backlit touch keys.

I am a little worried as the internal microphone seems to be connected to a thin plastic strip on which LEDs and touch keys are connected.

Touching at that point scares me .... especially if I approach the soldering iron on .... :rolleyes:

I will try to take some photos and post it on this thread ... :fingers-crossed::laugh:

The two PINs to be welded should be highlighted on the attached photo.

xyauto_ui2_9218DH_full_8227L_demo-ota-20200110_DSP

hi guys i found the soloution and i tought its better to share

1st the 9218DH is completely diffrent with 9218c-91218DL-9217-9216-9213

2nd for the HU with DSP chip inside you have to find the firmware with dsp in end of it

xyauto_ui2_9218DH_full_8227L_demo-ota-20200110_DSP

3rd update is very easy

format a usb flash drive with fat32 format system, put the zip file in root of flash drive connect to 6 pin useb cable(if you connect to 4 pin the update will start but will failed after 1 min)

from the HU Go to Car seeting-Sytem info just touch the Android Upgrading Bottom and sit back

its take about 5 minute to complete and enjoy it

for firmware you have to find in 4pda.ru dont worry if you dont know russian like me:D;just use google translate and looking for zip files which is same with your HU model number for example

xyauto_ui1_9218DL_full_8227L_demo-ota-20200106_DSP ((9218DL is suit for tesla models 12 inches Horizental device)

xyauto_ui2_9218DH_full_8227L_demo-ota-20200110_DSP

this two firmware is diffrent because of one word differ L&H

it's worth trying to upload YT9213A_00009_V001_20191126 to your damaged device. maybe it will succeed and work. and select preloader when uploading in sp flash tool.

with bricked radio probably the computer will not detect you radio via usb (4pin) and you will have to try through test points to detect when uploading.

unless you have a backup and you need a preloader and scatter to upload it, I can get the files you need from it.

---------- Post added at 09:54 PM ---------- Previous post was at 09:27 PM ----------

after testing this version of Rooted TWRP firmware 20190523 HiFi, I returned to the original firmware. because these firmware with our version of the yt9213 device do not work all functions. euqalizer does not react at all (as if it were inactive), the volume at level 1 is as loud as at level 10 or higher and it does not go down. somewhere on the Russian forum I read that yt9213 does not have the physical components as yt9218 and others and therefore some functions will not work with us

hi Pajurpl

Last night I took a small step forward but also one step back on my YT9213B device . :(

I managed to download the two ROM files; at the end of the third attempt the files were found to be functional and unpackable without errors.

The problem was with the MEGA server, not with the files !!! :silly:

I immediately tried to restore the device with SP Flash Tools.

This time I got a different message (not enough internal storage space).

I searched the net for a solution and a video on YouTube advised to try to remove the flagh from CACHE and from USERDATA.

I clicked the download button again and this time the download started !!! :laugh::good:

At the end of the procedure I turned on the terminal and a startup logo (AUDI) appeared but the device stopped and remained on showing only the Audi logo :rolleyes:.

I restored the ROM again by loading the other version of the Twrp ROM removing the flags from CACHE and USERDATA.

A new error appeared to me but this point at restarting the screen presented the image of the robot with the belly door open :mad:.

I reloaded the first version ROM and the PC after it reached 50% SP Flash Tools made me see a connection error. :crying:

I turned the device back on .... you can see the light behind the screen but it remains black and what worries me most is that it no longer connects via the USB, is not recognized by the PC.

The adventure continues ....:cowboy: .....
[Android Head-Units] pajurpl:
i find in page 45 this method

"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."

Hi Pajurpl :good::fingers-crossed:

your advice worked !!!

the device has awakened .... :victory:

Quickly connecting the negative pole from the poin test to the negative pole of the power supply, he recognized the port and started to load the ROM

I always got the message "memory error not enough space" and I tried again removing the two files CACHE and USRDATA.

With this method, the upload was successful and it seemed OK.

Unfortunately now the AUDI logo appears on restart and then the small robot lying down, the AUDI logo reappears every now and then the small robot reappears. :rolleyes:

It goes on like this forever (loop).

Now I will wait some time 30 minutes and I will let you know .....

:cool: However, I'm happy and I'll thank you forever ... it seems that the device seems to be recoverable ... :laugh:

EDIT : nothing happened, I had to turn it off ....

I hope to find a solution.

Hi

here are some photos of the external microphone connection.

The car is a Suzuki Jimny.

The microphone is that of the old Kenwood radio which was removed and scrapped, the rest of the material I found at home and recovered from an old PC card.

At the beginning I wanted to weld it vertically but it was too high and the device could not be closed then I soldered it horizontally.

I have tested the operation and the voice is now feeling very good.

There are two reasons why the microphone was not working properly before.

The microphone capsule in my opinion is too small and was found in depth in a very small hole, at the same distance that is inside the reset button, too much inside !! .

Hi everyone,

Recently I have successfully installed a new rom in my unit with YT9216B. After installing I have encountered 2 problems, one that I have solved was that the touch buttons on the left side of the screen were not configured.

The other problem that I have is that the buttons I have on the steering wheel don´t work and with the original ROM worked.

If I am not poorly informed, the steering wheel buttons work thanks to the CANBUS, could someone tell me what the solution might be for the buttons to work?

Thank you so much and sorry for my english
[Android Head-Units] rockrider81:
Yahooooooooo

this is the right ROM !!!! :laugh:

I will never stop thanking you for the help :highfive:

Loaded with SP Flash Tools without errors, now my second device works 100% as it originally did.

The loaded rom is now YT9213A (before it was B) ;)

Opening the back cover to access the test contact, I noticed that the motherboard of this device (iMars 7) is different from the others, a audio CIP is missing and there is another one more positioned differently.

There is no front and rear speaker balance adjustment.

For the rest I do not notice any differences with the one to which I connected the external microphone.

:confused:Hi

I have to ask you a technical question. :confused:

I have a friend who wants to buy one of these 7" 2 din devices but I can't recommend it well because even if externally they are all the same they have different motherboards.

There are dozens of offers on the Aliexpre store and it is not clear what you are buying.

What do you think is the best model? :eek:

The differences I noticed are:

- RAM memory (1 or 2 GB / 16 or 32 gb))

- Android version that goes from 6 to 9.1 (true or false?)

- Additional radio CIP present or not present

- HI FI mode present or not present

- Front speaker volume adjustment present or not present.

Prices are almost all around € 50 but some models cost € 20 more than another.

Is it worth spending € 20 more?
[Android Head-Units] abdollahimo:
Here is my idea

For sure you have to buy at least 2gb ram device because 1 GB will cause crash time to time

About rom you can device but 32 GB is better may be you need it in feature

Android version all is fake they are all on android 6 but it written 8.1 or 9.1

But be sure to find the model with DSP CHIP inside

It's all about 8227 motherboard but for sound quality and better adjustment I prefer to look for HANSTONE BRAND low quality in display resolution but sound quality is perfect

Hi

I confirm the procedure to restore USB recognition and to be able to use SP Flashtools again.

I did not want to solder a wire to the test point contact but I leaned over the tip of a clip wire crocodile, the other terminal was connected to the negative pole of the device (attention! Wire and yellow and red joined, otherwise it will not turn on).

On the tip of the crocodile I put a little piece of tin wire.

You must be fast enough.

When you press the download command, connect the USB port and always keep the contact on the test point.

When you see the red line appear, remove the contact from the motherboard and connect it quickly to the negative pole of the power supply and do not turn off the device until it is fully charged.

You will see that the download will be successful.

As pajurpl says you must have a ROM compatible with your devices; or you need to know what type of ROM you originally installed (yt9218, yt9217, yt9216, or other) and download it from the internet

Hey, did this solve your issue? My unit has really bad microphone. I contacted the seller and they sent me a replacement unit with external mic connector for free. This still didn't solve the issue. I was wondering maybe I should remove the internal mic and solder in a better mic.
