Soft touch buttons not lighting up

Hello Good People,

I have two questions I am in need of help with

#1.

My soft touch buttons have never been lighted up since day one. I am wondering if I have the wire connected or not. I used the orange wire from the harness as it said its the illumination wire. After reading and doing a search from the forum I learned that Viktorsaari connected the his illumination wire to the red power wire to have the touch buttons always on when the unit powers up. I did the same thing and still no illumination. When I go to factory settings and click on the soft button option it tells me to go to lighting debug?

The only remaining wires on my harness is:

KEY1 and KEY2

What am I missing?

#2

Anyone have a front view camera working with their unit?

I installed a USB camera with the hope of using Sygic's Real View Navigation. The USB camera came with its own ADAS app which works, but the camera does not come or is made available when in Sygic. I did a search on the 4pda.ru forum but with no success.

Any tips of this would be very appreciated.

Thank you :)

Android os: Android 8.1 Go

XY AUTO: 3.0 (8227L)

CAN BUS: 3.0 (8227L)

DDR: 1G

FLASH: 16G

cpu: A7 1.3GHz x 4

Capacitance: 10000 uF

Amplifier: AC7315 MOS bile duct 45W X 4

My Question

1. My device can flash firmware from 1st post?

2. if i need to update firmware to new UI5 (Now i use UI4) can i flash "Firmware 20190522 HiFi: (Link) (Thanks foxgiggle , iSevenAuto)" from 1st post (I gues, it's a new firmware and i hope it come with new launcher)?

3. My device is not have a Mic connect (only build-in Mic) but i found a pin connector from 2nd post, can i direct connect Mic to pin A19 and A20?

Thank you
[Android Head-Units] fani:
Don't update, Your firmware is already newer. 20190729

Also its slightly different veriosn YT9218DH_AHD

Launchers sometimes misbehave like that, when there are more than a couple installed.

try uninstalling others and keep only one or 2. and set its permissions in Android settings.
[Android Head-Units] fani:
If it didn't work since day one, then probably there is a fault. When you opened the unit, did you noticed any unplugged connector or ribbon cable? if you ever open the unit, you can try the LEDs with multimeter, if they even light up.

well.,,, not the way you want to use it, but I have mine set up through a switch and relay, to work as front parking assist (when needed) spliced into the back camera input.
[Android Head-Units] fani:
Ah,, bummer... we'v all been there at times.

try unzipping the update file (the ones named xyauto***full_8227L_demo-ota***.zip ) into a fat32 formatted usb, connect to usb1 or 2 port and boot up. it might start updating at boot.

Otherwise, You probably have to restore the boot1 partition from the backup.
[Android Head-Units] SHAMBALA:
Thank you viktorsaari for your reply,

I have set permissions in android setting to use UI5 as a default launcher completely, but my problem still occur. How can i do?

Thank you
[Android Head-Units] scheichxda:
Hello and thank you

I have (unfortunately) no backup of boot1 - is there a chance to take that from xyauto***full_8227L_demo-ota***.zip

ciao

ho letto un po...ma con calma leggo bene :)

però volevo chiedervi

perchè il mio legge su usb la musica e il video ma non sento l'audio

e cosi anche per il telefono niente audio :(

cosa devo fare ?
[Android Head-Units] scheichxda:
Hello and thank you very much.

I did download a ROM corresponding to a yt9217

Now: How to transfer?

Do I have to edit the scatter.txt?

Or take the latest update, copy the ROM to it (instead of boot) and upload?

Thank you in advance

Regards
[Android Head-Units] PamelaGirl:
Thanks for the reply, much appreciated.

As much as I would like to get those soft touch keys lit up the thought of removing the unit from the car AGAIN and opening it up makes my blood pressure increase to the point where it aint fun or funny anymore. I think I will look for some type of app that allows for floating controls.

Thank you again :)
[Android Head-Units] fani:
Read the first post, it has all the info regarding different procedures. :good:
[Android Head-Units] Raptordin:
I am still confused. :)

Hello there.

Please do not tell me to read as I did so either I can't see it or I actually can't see it.

I have read the first post and went also to the Russian forums and all are awesome and well explained.

But for the hell of it I do not seem to get the following;

1- how do I access recovery mode.

2- where are the actual recovery files and how to flash (From USB)

3- where are the files for Root and how to flash (From USB)

My Firmware is good and I do not need to flash a new (Older) Rom thus all I need is to flash recovery and root.

So I Can't seem to find the actual files nor do I know how to access recovery to flash from USB.

Moreover, I tried to put a Rom (Just for testing) and tried to upgrade from settings and it reported wrong version.

My head unit information are as follows.

"

Android: YT9217B_00002_V004_20190808

Android os: Android 8.1 Go XY Auto: 3.0 (8227L)

CAN BUS: 3.0 (8227L)

DDR: 1GB FLASH: 16G

cpu: A7 1.3GHz x 4

MCU: 3.1 (8227L)

good morning

i succesfully installed the correct rooted version on my 8217b and the only problem is with the physical butto that not work corretcly, is there a way to fix it?
[Android Head-Units] fani:
About accessing Recovery, Page 74, Post # (732)

Rooting not possible via usb flash drive i'm afraid, you need to use PC and spflashtool. TWRP file and info at

page 74, Post # (738)
[Android Head-Units] fani:
yes, its mentioned in 1st post.
[Android Head-Units] Raptordin:
Thanks.

Thanks a lot for the information. It would be a problem for me to disassemble my Head Unit to access recovery then.

I could get my Laptop in the car and try the SPFlashtool if I can use it to flash and access recovery. If not then I am out of luck.

Thanks again and have a great day.

[Android Head-Units] xxgeorgegr:
Well I formatted a usb stick fat32 and put the zip xyauto***full_8227L_demo-ota***.zip and i renamed it to update.zip. and for the first time after 10 mins of boot loop it recognized it. But it gives some errors:

1.Can't find system/build.prop in usbhost/update.zip

2.Warning: No file_contextsThis package is for "8227L_demo" devices; this is a " "

3. E: error in usbhost/update.zip

What's the problem? I can't understand

At motherboard there is no xyauto model

It only is written CM103_MB_4.0_180712
[Android Head-Units] fani:
it looks like your motherboard is a different model.

Did you ask the seller for the update file and procedure? otherwise if you are updating at boot, then the zip need to be extracted into a folder named XYAUTOUPG

Hello

So I did but still having a question

May I show you what I did up to now?:

After installing Smart phone flash tool (reading instructions.docx before) I deflated "Memory Dump Rooted TWRP 20190523 YT9217C HIFI"

After "transferring" the scatter.txt to the Smart phone flash tool I got three options

- boot

- recovery

-android

If I understood the "instructions.docx" it is better not to check boot.

so I read in your instructions on page 1

"Load scatter file and preloader (Link) in spflashtool."

I have a corresponding preloader to my device. But this preloader (recovery-twrp-UI2_20190127-1726_20190616-2013) has no scatter.txt file.

But this boot.img is not the same as the one in "Memory Dump Rooted TWRP 20190523 YT9217C HIFI"

Do I have to substitute the preloader that is corresponding to my device with that from "Memory Dump Rooted TWRP 20190523 YT9217C HIFI"

Or do I have to expand "Scatter and Preloader.rar" and take "MT8127_Android_scatter.txt and preloader_8227l_demo.bin"?

Looks like you are mixing two different procedures. Memory dump is raw hex data. You need to follow "Memory Dump Procedure" for that.

*.img files are part of the firmware, which should be uploaded using "Uploading Firmware (full or parts)" method.

Use the scatter and bootloader which works for your device. There are multiple to chose from. (links in 1st post)

Best of luck.

Do I understand the howto on Page 1 in the right way?

Hello

I am trying to recover my headunit via Memory Dump Procedure as explained on page 1

"Memory Dump Procedure:

Load scatter file and preloader (Link) in spflashtool. Press Ctrl Alt V , then go to Window and select "write memory". In file path select "user", in begin address put 0x0, In Region select the partition named "EMMC_USER". Hit Write memory. "

Does this mean:

I take the scatter file and preloader to SP Flashtool (Folder: Scatter and Preloader)

and

In file path I select "user" from the dump I want to transfer (Folder: Memory Dump Rooted TWRP 20190523 YT9217C HIFI)?

Additional question:

In my version of SP Flashtool I had to rename the file "user" to "user.img" otherwise the file is not shown in SP Flashtool.

Is it possible that this is the reason for errors.?

Waze mutes background music (like Spotify)

Hello Guys

My HU was an annoying thing which has been solved with a new firware 20190522 and new MCU 3.1. The issue was that when Waze started to tell me the directions music which was played in the background stopped and seems music player (I use Spotify) killed. Now with the new fw and MCU it is working great. Music volume going down while Waze speaks then goes back to the normal level when Waze stops speaking.

Hello and thank you

Yes I did : go to Window and select "write memory"

I was - after reinstalling Windows - able to write Boot_1 and Boot_2 - but the error is still alive.

When trying to write "user" I get the message:

ERROR: S_DA_INVALID_RANGE [3049]

I did edit the begin address to : 0x0

In the file "partitionsize.txt" of the dump I used I can read:

EMMC_PART_USER	Size = 0x00000003a800000

Do I have to write instead of: 0x0 the term 0x00000003a800000 to have a successful flash?
