Hi

with the method I described here I solved 90%.

Now the voice is heard well and you can make a normal phone call.

Before the change it was practically impossible to speak to the other party because of the badly positioned microphone capsule.

To understand what the defect is, just insert a paperclip gently on the reset hole and if you reinsert it on the MIC photo it will enter for almost 2 cm which is the same distance as the reset button, too deep (do not press too deeply to not break the capsule).

Although the change may be fine, I want to try to achieve 100% quality by applying a very small preamplifier.

But it's just my personal craze .... I'm too geek :)

Hi

you must insist on the method shown on the first page, or try MY method and you must be fast enough to move the negative pole contact.

Your big problem, however, is finding a ROM compatible with your devices (scatter etc).

Did you make a note of the ROM before blocking them? (YT9213 YT9216 etc.) :eek:

Device manager won't show anything, unless spflashtool is up and running and expecting a connection, at this point, you plug in the device USB cable to the computer while shorting the test points.

Keep experimenting, it will work eventually :highfive:
[Android Head-Units] Panja83:
You can try this

Microphone volume:

1. Go to the MTK engineering (app from playstore)

2. Hardware tab

3. Audio item

4. Point Headset (it is he who changes the volume of the microphone on the face)

5. In the drop-down list, select Mic

6. The Level parameters are written off on a piece of paper.

7. Level0-Level 10 I had values ​​from 180 to 255. I set everything to 240 (at 255 the interlocutors said that they hear themselves if I have a high volume of speakers. Accordingly, if you have too much noise or excessively loud, then can experiment with the values). Level 11-14 I had zeros - I left it.

Goodmorning everyone

finally last night I made the changes to the devices as I had planned at the beginning and I want to share the experience.

NOTE !!!!!!!!

- before making any changes always DUMP your ROM, follow the instructions on page 1

- this procedure can be useful for those who do not want to risk dangerously loading ROMs at random to obtain TWRP and ROOT

Installation of TWRP + MAGISK (root) + MAGISK MANAGER directly on the original ROM.

Procedure I used: With SP FlashTools

- from ROM YT9213A kindly (sent to me by Pajurpl whom I will thank for life :) :good: ) I opened the scatter file

ATTENTION even if they are similar files everyone must use the scatter of their ROM.

- with the mouse I deselected all the lines and I left only the recovery line selected.

- clicked on the Recovery line I selected the TWRP recovery from the PC disk that I copied from another Russian YT9213A ROM.

- NOTE ! after clicking download the upload started but it always stopped with an error message regarding the connection which was strangely disconnected.

I clicked download again but at this point I immediately turned on the devices and the loading was successful !!!

While loading the screen was on but remained black.

I turned off and on and through the free apk terminal emulation program already installed I typed the command line "reboot recovery" and I hit enter.

At the start of the TWRP recovery I entered settings and I deselected the program timeout .... unfortunately it doesn't get along very well with the device, and then who cares ... it's always connected to a power supply :).

With TWRP then I loaded MAGISK.zip.

At power on I then loaded MAGISK MANAGER APK (required to manage root permissions etc.).

At the end with Root Cheker I checked if the root was installed correctly.

End

Car Settings in Alps 8227L panel

Nice bro, I've a question. As showing in your 3rd shared pic, there is an option of Car Settings. When I press it in my same android panel, it says "There is no Car configured to this device."

How to configure this option according to the car? :confused:
[Android Head-Units] fani:
its the same here too. No car configured. May be someone can shed some light on this?
[Android Head-Units] lemmon:
I think that menu is only activated when you connect the radio to the car’s can bus system
[Android Head-Units] spedward777:
If CAN is connected you can go to factory settings and change "protocol settings" I think it is (it is in the top left corner) select the proper protocol and vehicle and it will provide vehicle specific options. Mine provides HVAC controls for my Honda. I bought the one with the controls and when I bricked that I just bought the generic device and kept same connections and configured it in settings. You can even check out car settings for some of the other vehicles but won't be functional.

1. I've decompiled the apk, then replaced some images,

changed some .xml code and recompiled the apk...

2. Yes, LauncherUI4 can get mods too.

What kind of icons would you prefere?

3. In the original apk there are some hidden widgets and the hidden feature for using 3 Homescreen pages with scrolling between those and hidden feature for adding custum app icons and/or 3rd party widgets.

This can be seen in the layout.xmls of Homescreen.

I will try to unlock/activate these hidden features in

LauncherUI2.apk...
[Android Head-Units] raphael.atienza:
1. Okay. I honestly have no idea how to do that.

2. Well basically I just want it to not have the Silver circle background (in the attached screenshot) and for it to look stock or look like Android Pie Circular icons (like in the second screenshot).

3. Oh nice. Okay that is way beyond what I know about customization of the launcher of Android Headunits. I just used Nova Launcher or currently the UI4 launcher.
[Android Head-Units] bitstra:
I'll try to patch LauncherUI4 for your needs.

Please give me some days, because I'm working on unlocking the hidden features in LauncheUI2.

[Android Head-Units] raphael.atienza:
What USB port did you use? The upgrade option for me only works on USB2. On USB1 it just fails and says update error. The drive is FAT32 and only has the zip file upgrade right?

Also make sure the USB drive works with the XYAUTOUPG for stock firmware method on USB1. If it does the upgrade via ZIP using USB2 should work on stock firmware.
[Android Head-Units] cafsta:
\

Yes my flash drives are in FAT32 format. I've used a 4gb which worked the first few times. The 16gb then upgrade android stays greyed out.

I tried port 1 and port 2 but neither works. Yes I had the upgrade as a zip file on my flash drive.

What do you mean "Also make sure the USB drive works with the XYAUTOUPG for stock firmware method on USB1."?
[Android Head-Units] fani:
Did you try formatting the usb drive with SD card formater? (mentioned in post 1)
[Android Head-Units] cafsta:
Yes I did. I always use the quick format option. Should I use the "Overwrite format" option?

When I select the software named option over the protocol parameter settings, the camera icon appears on the screen, and when I press it and shift into gear, the camera works.

Does anyone know why it doesn't pass automatically?

OK having had no problems with a flat battery after switching the power line to aux only, I decided to try other power modes today.

Reconnected to +12 via an ammeter.

Currently Power in user mode:

Power on unit on 800mA

Power off unit off 500-600mA (waited for 2 minutes)

Into engineering screen and changed power to sleep mode (engineering mode code in this thread)

Power on unit on 800mA

Power off unit off ~1mA (after about 20s)

Screen still dies when key removed (correct) and now it will not drain the battery weekly.

Much better, hope this helps someone else.

[Android Head-Units] rockrider81:
I too have a Suzuki Jimny !! :)

To solve the microphone problem you have to disassemble the device and then you have to disconnect the microphone capsule (just cut one of the two poles with a small scissor)

Then connect an external microphone that you can buy in any store.

See HERE

REVERSING CAMERA :

You must connect the wire with the plate where it write "BACK" to the positive pole of the white reverse light bulb.

When you engage reverse gear, the camera activates.

The black and red cable connected to the camera is used to power only the LEDs and must also be connected to the positive pole of the reverse light bulb.
[Android Head-Units] oguzhansan:
ABOUT CAMERA:

As you said connections, however, the image comes only by pressing the virtual button on the device. there is no image when reverse gear is engaged

Anyone know what is the most up to date version for YT9217B? USB or SD card version

Thanks!
[Android Head-Units] rockrider81:
mmmm ...... :rolleyes:

It is not possible ...

With the engine off and the keys inserted and the engine connected (first click of the key clockwise), engage the reverse gear and check with a tester that there is a voltage of 12V in the electrical wire labeled "rear" or "back" or "reverse" .... (contact 5)

I don't know what color the thread is, you have to check on the scheme provided by the shop.

I combined a thin red and black cable with the cable of the camera which I connected in parallel to the wire of the reversing light bulb, wrapped it with the black cloth tape and passed it under the plastic covers of the car, in this way I reached the dashboard and I was sure to have the voltage of 12 Volt in the red and black cable every time I put in the reverse gear.

Long live the Suzuki Jimny !! :)

Even if it's my wife's car ....

Hi

I have one of these 8227l head units and I'm really happy with it. The only thing I would like to change is the annoying picture for the music player of some random singer on the home screen. I thought it would display album art and change with the track but it seems to be a fixed picture. Does anyone know how to change this or delete the picture from system? Id rather have a blank circle.

Also, I'd like to delete the 3 preinstalled songs but can't find them anywhere in the file system. They show as being in the folder 'insidefiles', but I can't find it. Do I need to root? If so, how?

Any help appreciated

See picture in 1st post for the subwoofer audio out pin on the back, there is no wire, so you have to repurpose one of the unused rca.

it will be controlled via the "subw" slider. if you don't have subw slider then try the "low" slider. it also has some effect on it.

Hello, I have the YT9213A / Android 9.1 / MCU 3.1, as you can see in the image http://prntscr.com/rzw9ll

My problem is that I can't control the balance or the equalizer. The icon doesen't appear on my device and when I move any slider from the equalizer, nothing really changes in terms of sound. I've heard that is a problem with the firmwire or something like that but I can't figure it out what should I do. Which are the steps in order to reinstall/reflash a compatible Rom for this model. If somone could help me I would really appreaciate it because right now this forum is my only hope. The sound is really ****ty and it doesen't worth to keep it at this state if I can't find any solution to fix it somehow. Here is a picture with the equalizer menu, where the audio settings icon is missing http://prntscr.com/rzwe9z

Also, when the rear (parking) camera activates, it doesen't make any sound to warn me about the obstacles distance.
