FYI to anyone looking at a microphone upgrade.

Attaching the microphone to the pin outs in the plug in adapter didn't work for me either. I tried a couple microphones and in the end burnt or otherwise damaged the board where the original mic sits but soldering the mic wires to the mic+ and mic- near the hole where it says 4G- works well.

Anyone notice people still can't hear them well on phone calls? OK Google commands work perfectly and even at high speeds. If I record a audio sample recording it plays back great, clear audio but when I am talking to someone via bluetooth in a phone call, they can't hear me at all.

Could it be a DAC conversion issue on phone calls?

Also, if you've never installed the Headunit Reloaded app you don't know what you're missing:

Hi

Has anyone managed to find a definitive solution for the radio without having to replace the original rom? :cyclops:

Unfortunately, the radio.apk link published on the first page is no longer active and I ask you whether to have an alternative link.

The terminal works well but even if RDS does not work the radio application however it does not allow to have a list of radio channels that can be selected and renamed in a practical way.

After the scan it creates a hundred touch buttons with writing on the frequency, they are not practical at all.

I would have liked a numerical list of even 10 memoirs.

Some idea ? :rolleyes:

Hello Guys,

Need some help here.

I already update my unit with YT9218C_00005_V003_20190225_HIFI ROOT TWRP USB through XYAUTO folder in usb disk and did the reset button...worked like a charm.

I changed the boot logo and boot animation - just perfect.

Now i'm trying to install radio apk with rds with no success...

I downloaded the file in the first page FMRadio.apk

And using root explorer replaced the file in System > priv-apps > FM radio also gave permissions 0764

Rebooted the unit but nothing... i open the factory settings - Radio Settings and have 3 options.

1 - Auto match

2- nxp6851

3 - FM

Mine was in nxp6851.. i changed to FM - rebooted

and if i start the radio aplication already show the new layout of radio app downloaded here but i can't discover any station.

I went back to Factory settings - choosed NXP6851 and the radio gone to default layout and discover stations...

Is it possible to use the new layout with rds and station names?! what do i need to do?

Thanks for the help

There is no workaround for the hundred touch buttons with frequency writing issue yet.

Boot looped 8227L with YT9216-VERO.1 XY AUTO 2019-03-20 board

Hi,

I changed the boot animation and logo and now have the loop problem. My PC doesn't see the head unit and I'm not having much luck getting the ROM files to work either. One file seems empty which I'm not sure is correct.

I made a little breakthrough last night, I attached a momentary switch to the 2 test points and found a way of booting my unit into recovery mode, I found that by applying power while holding reset, release reset then hold the switch attached to the test points. As soon as the recovery mode appears pressing the switch cycles through the 3 options, recover, normal boot and fast boot. However, I can't invoke any of the commands as I don't have a VOL- button, the switch attached to the test points seems to be functioning as VOL+ as per the response and what the screen is displaying.

Has anyone found a way of running recovery using this method? I tried a USB keyboard but that doesn't respond, will try a mouse later too just in case that works.

Thanks

Ian

You need to run the learn routine for the soft buttons

To recalibrate the touch screen, it is necessary to place the palm of your hand on the screen for several seconds and the calibration appears. At this point, 4 dots appear. touch each point when prompted and the screen will recalibrate.

The system then asks if you wish to enter touch button learn, click ok.

Here you see a screen that has different boxes with a function, in the case of this product there are 5. Touch the box labelled " Start" then select one of the five functions. Touch the corresponding function button running down the left side and the system will learned the position on the touch screen for that function. Repeat the process with all others then touch the large orange box to close the learn function. After pressing ok, the new parameters are displayed and the screen is fully calibrated.

Do not connect you head unit to you pc, first open the flash tool, select files then connect the usb cable to your head unit. For me I didnt need to connect 12v, try with just usb but be aware the screen will not light up but doesn't mean there is necessarily a problem

Hey guys, Im thinking about buying this HU to my work car, which I'm using for long trips across Europe and need navi. I've read one user review on BG that this unit is not capable to play music via spotify on background while using navigation, that there is slow down and lags, could someone confirm that? I know this unit wont be the most smoothest ever for those money, but the only thing I need from it is turn on waze or sygic and play music from phone with bluetooth or via spotify app. I've watched tons of video reviews but no one shown this "multitasking".

I'm freaking out !!!! and I have to ask you a stupid question, and I'm ashamed of it.

I have read dozens of forum pages but I cannot understand how to connect the device with SP FlashTools.

I can't understand how to set up the device before clicking the "download" command.

I tried to connect both USB sockets, it doesn't work

I tried to turn it off completely ... it doesn't work

I tried to click "download" and turn on the device ... it doesn't work

I tried pressing RST ... it doesn't work

In all ways the download does not start.

Is there a combination of buttons to press to activate USB mail as a host ?

I have been using mediatek CPU devices for years but this model drives me crazy.

I can't even connect it with MTK Droid Tools which usually connects any Mediatek.

I humbly ask for your help ...

PS: I would also need a working TWRP recovery for this unit.

I extracted one from a Modded ROM ... but I don't know if it will work ... I don't trust much ...

At this point if I can not connect the device to SP FT I could also try to load a complete ROM via the key but I'm afraid of finding myself a brick paperweight.

I don't know if the ROMs around are compatible and which one I could load.

Do you have any suggestions for me? :eek:

Do this in this order

1. Make sure your head unit is not connected to anything.

2. Launch the flash tools, select the 2 files you need.

3. Connect just USB to your head unit.

4. Back up your ROM.

5. Download you files to you head unit.

Hope this helps

flashing wrong firmware on YT9218C 2/16

Hi all,

I have a YT9218C 2/16 HU and has been struggling this few days updating firmware on it.

First, I flash using the YT9218C_00005_V004_20190624_HIFI (UI1) FLASH.rar file and it's successful.

Then, I flashed the firmware YT9216C_AHD_00005_V004_20191017_HIFI (2_32) UI3 FLASH.rar and was also successful.

Both use the XYAUTOUPG method (reboot and update from flashdrive)

I got these files from [MENTION=10042218]Maxkir[/MENTION]'s post on "Head unit ML-CK1018 and similar, based on MT / AC8227L processor" thread on 4pda.ru, referenced on the first page here.

The problem is, after I upgraded using the 2nd firmware, HU could not be full shutdown when the car engine is turned off (ignition off).

When my engine starts, HU enters the home screen in few seconds. There is no boot process as normal.

This causes the battery drain and the engine hard to start.

I am sure it wasn't caused by the wrong cable installation, because at the beginning of the installation I did not experience this problem.

The stock firmware takes long time during the boot proccess.

I tried to flash the first firmware again use the same method but it didn't work.

Using the QuickBoot application from playstore, when restarting the system doesn't detect any upgrade files on the flash and boot as usual.

I also tried using a file xyauto_ui2_9218C_full_8227L_demo-ota-20190522_HIFI.zip through the upgrade menu in the system info. But getting the error message "the upgrade file version is incorrect"

And my fault, because I haven't understood the use of SP flashtool, I don't have a backup of the stock firmware to restore

The question, how can I flash it again using the firmware I want and which method should i try.

Until now I haven't found a detailed explanation using SP Flastool to install firmware on this unit. Already download + install the driver and the app, but cant manage to download the file into the unit.

I dont even know that my laptop is connected or not. No progress when click the download button.

Any advice will be highly appreciated

Now raise another question,

- Does this Quickboot feature consume power when engine off? Cause it drain my battery

Sadly i still cant upgrade using XYAUTOUPG method, not sure its the flashdrive problem. Since i've been using it to flash it before

Subwoofer Output Pin

For anyone having trouble with the subwoofer:

The default AUX_out pins on the back are actually the Mid-range outputs and controlled by the Mid slider in the mixer.

The pin highlighted in the picture is the Sub frequency output (Mono) and controlled by the Subw slider in the mixer.

What I have done is rearrange one of the aux pins to that location and use the same signal to amplifier inputs.
