Hello,

I have a px6 unit and I have a couple of questions - issues, if anyone knows.

First of all, bluetooth stops working after a couple of start ups, bluetooth name in the settings is blank and in order to get it working I have to select the bluetooth mode ( the same mode ) in factory settings and reboot once or twice. After that it works just fine.

Also, can I use a different music player? I am used to using folders and in the embedded app there is no such option. I have installed a different app but I think I need to set it as the default player somehow?
[Android Head-Units] _yuzo_:
Try updating MCU and firmware. Also there could be a power issue. Check if the module has 3.3v.

There is no way to set the player as default. The default music app is a part of CarUI.apk
[Android Head-Units] bkran:
Thank you for your reply. I think though I have a later firmware version installed from the ones listed in the first page. I have asked the seller off course but they seem to take their time responding.

When you say to check the voltage, do you mean on the board with the board? Wouldn't want to try that, not too familiar with these kind of things..

Somehow out of curiosity, would there be any significant benefit to upgrade for people like me whose units work well with the existing firmware except for relatively minor issues such as button binding (cannot bind multiple buttons to apps)? What would be the tangible benefits of a new firmware? Thank you so very much!

I got an Erisin 8715V bwith A10 and updated to latest firmware with erisin launcher (thanks to the author!)

Can i update to latest version without erisin launcher? Any screenshots of normal version? And does the normal version store fm radio names instead of frequency?
[Android Head-Units] Exutor90:
Good evening.

I hope I can disturb you.

I currently have CSN2_D software on my Erisin 8791V radio. SCREEN 2

I would like to have the latest software.

Unfortunately I always get an ERROR. Screen 1

I use a USB stick.

What am I doing wrong?

Here are a few screenshots.
[Android Head-Units] fight2k:
Format UsbStick

Put kupdate into it

Connect to the usb in your unit

Put stick or something into hole "reset" and hold until led pannel flash 3 times then relase stick and instantly press it again.

You will see progress.

Do not forget to backup yours apps etc. , update will remove your data. So fresh start like factory new.
[Android Head-Units] _yuzo_:
The answer is simple: your unit runs android 9 while you're trying to install android 10. If you still need that, please follow the instructions on the first page and install android 10 using pc/laptop.
[Android Head-Units] Exutor90:
Good Morning. In my Radio Settings stands Android 10.0 not 9.0.

[Android Head-Units] project2:
The latest posted version runs way smoother than the latest erisin one.

Also the fm radio doesnt start anymore when powering up. Great!
[Android Head-Units] Exutor90:
MCU have been updated successfully.

I have now This one

But how can I get the newest Software?

I have android 10 say my Navi
[Android Head-Units] _yuzo_:
Again. Your unit runs android 9!!! The error about platform rk3368 instead of rk3386_Android10 means that! No matter what in the lot on Ali (or in some other store), or seller, or even android version in your unit says! That is android 9 (could be fake android10, that is equal to android 9).
[Android Head-Units] _yuzo_:
Radio does not start on powering up if it was closed by "back" button in top right corner. Otherwise it starts on the boot.
[Android Head-Units] project2:
Nope. It doesnt start now even if it runs when i switch the ignition off and back on
[Android Head-Units] criszz:
What rom version ?
[Android Head-Units] goy2k:
Just like me, you have a "fake Android 10" (rk3368_Android10 in the messages) on the ERISIN. I have the ES8783 and had the same error. You have to update to a real Android 10 first (see at the very beginning: https://xdaforums.com/t/...2_8600_d-android-8-9-10.3912413/post-79144645). It worked great for me. You can then install any new A10. The firmware versions available here (especially the last two) seem to come directly from Erisin.

PS: looks harder than it is.

PSPS: the correct USB port is marked with a flag at ERISIN that says OTA :) you don't have to search long

Hi, as I see you're from Germany, so my answer in German :)

Du hast genau wie ich ein "Fake-Android 10" (rk3368_Android10 bei den Meldungen) auf dem ERISIN. Ich habe das ES8783 und hatte den gleichen Fehler. Du mußt erst auf ein richtiges Android 10 aktualisieren (siehe ganz am Anfang: https://xdaforums.com/t/klyde-px4-p...2_8600_d-android-8-9-10.3912413/post-79144645). Hat bei mir super funktioniert. Danach kannst du jedes neue A10 aufspielen. Die hier verfügbaren Firmware-Versionen (insb. die letzten beiden) scheinen direkt von Erisin zu kommen.

PS: sieht schwieriger aus, als es ist.

PSPS: der richtige USB-Port ist bei ERISIN mit einem Fähnchen beschriftet, auf dem OTA steht :) da musst du nicht lange suchen

Hey Guys. I have a PX5 Erisin with CSN2 MCU. I updatet my car with a AMP. Now i have no volume with the android head unit. The original is working great.

I have read, there is a setting named "examp". But i cant find it.

Where is this setting or how can i fix it ?
[Android Head-Units] Exutor90:
Where can I find the right USB Port for Update Android 10 for Erisin?

I can only find 2 Ports by Cable.

3G USB

Carplay

This two are wrong.

It came this error at the red X
[Android Head-Units] gassnico:
in my case when I tested USB port one was declared as ehdci and one as xhdci and in fact the xhdci worked for OTG !

[Android Head-Units] Exutor90:
Thanks Nicolas.

Do you have the same Ports like me?

3G USB and Carplay? By Cable?

Which Unit do you have?
[Android Head-Units] gassnico:
no I don't have the same !

but one of them should be an OTG one !

you can try to search on russian forum with google translate if someone already had this kind of USB naming.
[Android Head-Units] Exutor90:
My 2 Ports are not xhdci

All 2 are ehdci

[Android Head-Units] _yuzo_:
Can you disassemble the unit and say the mainboard revision?
[Android Head-Units] Exutor90:
Yes tomorrow. I think it's 1.2.

If yes then I must build a new Cable right?

Or no chance to upgrade Android 10.0?

Thanks
[Android Head-Units] Saiphable:
Make cable like in tutorial, swirch to mascrom mode and burn android 10
[Android Head-Units] goy2k:
On mine the right cable is marked as Carplay/OTG
[Android Head-Units] Exutor90:
When I test the Carplay cable for update can I destroy my unit when this cable is wrong or does the update cant start with this cable because it's not OTG?
[Android Head-Units] Exutor90:
What is Mascrom Mode?
[Android Head-Units] _yuzo_:
Not destroy, but make it a software brick and then soldering skills are required. You need to know what to do and how. And read instructions carefully at least 3 times.

The only known scenario where I do not know how to fix the unit without motherboard replacement - unsuccesful or interrupted upgrade of MCU firmware. Android part is a simple thing to fix if you have skills.

Mind that no one there will fix your unit for free in case of failure. If you have no problems with the unit, leave it as is.
[Android Head-Units] Exutor90:
So it's better don't make risk with an non OTG Port and better to build a cable and a new OTG USB Port like your instructions?!
[Android Head-Units] Exutor90:
I only have one known problem.

My steering wheel buttons don't always work.

Sometimes yes sometimes no.

With my old device everything worked perfectly and without any problems.

And so is Carplay. When I connect my cell phone it always takes 10 minutes by car until everything works, otherwise everything breaks off.
[Android Head-Units] _yuzo_:
You can do nothing with unit in terms of upgrade to android 10 via non OTG Port. Once you run andriod apk to start an upgrade your unit will be temporary bricked and only direct connection from PC via OTG Port can unbrick it.
[Android Head-Units] Saiphable:
Maskrom mod is option how to switch HU to OTG mode. So you can burn android 10.

[Android Head-Units] Kenlider18:
I, made it to update to the latest version, and I'm still having the problem, kia logo then android is starting and then restart after a minute, and looping again, what else I can do? When I first buyed the radio it didn't have a kia logo, I picked in the interface, but after restoring and reinstalling firmware logo is still there! Wasn't suppose to erase everything?
[Android Head-Units] _yuzo_:
Logo is copied to the partition which is not modified during the firmware upgrade. So that is expected behavior.

Check the power of coreboard (see a schema in the heading post). It should be powered from +5V (Page 3, pins A5, A6). If you have less there, change all electrolytic capacitors. Do you have a LTE modem on board? DVD? LTE consumes 0.6A and could cause bootloop if the +5V line have less than ~4.8V
[Android Head-Units] ecolibra:
I need your help friends, I try to find out in the forum but I am lost ... the seller has offered me an update to android 10 to solve my problem, my radio is a px5 csn2 (I attach an image) now I have android 8, I can install the Vendor upgrade to android 10 directly from a USB stick?
[Android Head-Units] _yuzo_:
NO. You should go using the instruction for upgrade via PC/Laptop.
[Android Head-Units] Kenlider18:
Yes it has a DVD onboard, modem I think yes, but not connected the sim card cord, once in recovery mode, never restarts Only while loading android and never reach to open, it's this also may be related to energy consume? I will, check everything you told me about capacitors.

I really appreciate your help! (Attached my radio picture?
[Android Head-Units] ecolibra:
Thanks for answering me, better then I install another update ... can you recommend an update even from android 8 more recent to mine or android 9? that can be installed by usb memory.
[Android Head-Units] ecolibra:
I have another question ... the only thing I want is that the original settings of the car appear, now I am missing things ... would it be enough then to update only the mcu? Which one do you recommend for my px5 model with android 8? Can I update it using just a USB stick?
[Android Head-Units] _yuzo_:
Symptoms say about weak +5V line. I can be wrong, but still that is most probable reason. Modem works even if there is no SIM card. Recovery mode does not require lots of resources, so it could be stable.

I can try to advise more, but I need to have measurements of power lines and maybe a video of updating firmware process. Also there could be a power button constantly shorted to the ground, but in this case the unit should go to recovery constantly instead of bootloop.

You can install only android 8 using USB stick. Take the most resent from the first post.

Most probably, no. As android part and app should be present to add some custom settings. I even not sure if the needed functionality is present in android 10. You can take the most recent MCU with DSP from the first post. I do not recommend updating it if you have no other issues. Install MCU after upgrade to android 10 if you decide to do that.
[Android Head-Units] ecolibra:
I just want the function of calibrating the wheels to work for me when the car warns me of low pressure in a wheel, everything else works fine for me. Is there any way to activate this function in any menu of the device? I mean to be able to turn off the tire pressure warning light that appears in the photo.
[Android Head-Units] Kenlider18:
i have checked voltage, dont know if i do that right, i leave some pictures, and im also uploading a video when checking voltage and installing firmware.

When picking from right to left a5-a6 reading is 0v, but if i pick a4-a5 it shows readings from 4.85 - 4.95 almost stable at 4.95

When picking from left to right readings are about 3.6 v.

also picking

Hello

This is the video where I'm taking the voltage,

it seems to be right, but picking A5 and A6 from right to left reading is 0v, I needed to pick a4-a5 and reading shows 4.95. if I start from left to right in the same position reading is kinda 3.6 v

I think my circuit board is different. But I count the pins and they are the same quantity. I'm uploading a video where I'm showing when installing a new firmware.

Any other thing to check?
[Android Head-Units] Kenlider18:
This is the video when installing firmware
[Android Head-Units] _yuzo_:
this point is correct and OK.

This video was really helpful. You have a hardware problem with android coreboard. The firmware is being installed for a long time, the formatting of /data partition takes something like 5 minutes, while in my unit it takes less then a second. Then android tries to boot, it tries to start the launcher and finally fails and restarts. It looks like a NAND memory failure. The rest of things I can say after diagnosing it by myself and replacing a coreboard. I would recommend contacting a seller with the problem - the unit does not boot. Maybe he will send a replacement of coreboard or whole unit.

If your unit has canbox adapter, it could be fixed on android 10, but there is no guarantee. I did not see such a function, to be honest.

Cam Hyundai 2019 Kona 2

After read Kona circuits diagrams I found the rear camera is controled by MM-CAN BUS, no direct connection with Monitor/Card Radio. Just there is needed some different trigger for fire up the rearview. As you told, in fact there is nothing to see as soon as camera signal just not came (not turn on).

If found also Hyundai 2019 cameras a NTSC, and I guess will work on next try to fix it.

is it possible to update CSN mcu to CSN2?
[Android Head-Units] Uk. Inte:
[MENTION=382443]YUZO[/MENTION]

Firstly, Thankyou so much for putting this thread together. There is so little information about CSN2 on the web but you have put it all together and written very good instructions for updating these new units.

I just wanted to report, I purchased a Pumpkin ND0293 and it came shipped with CSN2_04162019_112307 MCU and Firmware build 201903151040

I didn't like the Pumpkin launcher very much and I wasn't too keen on the way Pumpkin skinned the Radio and Music app as they had a transparent background which didn't suit me as I use a KLWP (Live wallpaper) for my setup. It made those apps look messy.

I was also having trouble with Voice dialing. Google assistant will follow my voice commands but will not make a phone call.

So I decided to try the May 8th firmware update (Note: Had trouble with 3 different SD cards on my unit, none would flash the new firmware so I ended up using a USB Stick). Overall I'm happier with the new firmware but unfortunately It has not solved my issues with Voice dialing. Is there anything else you could recommend I try?

Thanks again for this wonderful thread. I will be following it closely and looking forward to what comes for our CSN2 head units.
[Android Head-Units] _yuzo_:
here is my step-by step guide re voice dialling written for 4pda community:

0. phone is connected via Bluetooth to your head unit (HU);

1. Press the voice (microphone) button on your wheel or open Google Voice search app;

2. Say what yon need. I told "Call Four Seven Seven" - point 1 on sreenshots (yep, Ukrainian is my native :) );

3. If the number is present in contact list (saved on Google side, in my case a short number 477 is there ) - point 2 on sreenshots ;

4. press 3 dots - point 3 on sreenshots ;

5. chose 'Bluetooth' app, we do not have 'Phone' app in our HU - point 4 on sreenshots ;

6. press Call button - point 5 on sreenshots ;

7. all further calls will be done automatically once the contact is found/recognised (I tried "Call Four Seven Seven" and "Call Wife");
[Android Head-Units] _yuzo_:
Do you have a picture of your canbus adapter? Maybe you can try to upgrade the firmware there. We have examples of update the canbus on KIA Sportage IV, most probably it this the same for all Korean cars.
[Android Head-Units] uk.intel:
I didn't find this because these options don't appear on the downloaded 'Assistant' app but I found them within the pre-installed Google Voice search app.

Everything works as it should now.

Thanks for pointing me in the right direction. Much appreciated.

Somebody that can help me

I bought this double-din for 6 months to this store in ali-express:

https://es.aliexpress.com/item/3297...ail.1000016.1.50353c5693alCc&isOrigTitle=true

The problems started about 2 months ago when suddenly the sound was not heard and the solo began to reinitialize. Each time he did it with more assiduity. I contacted the seller who sent me a new firmware with instructions to install it. I try it and it stays at half installation it restarts and enters bootloop. I get back in touch with the seller and start apologizing until he stops answering. I've been looking at how to fix it and I found this forum. I have downloaded the firmwares of the first page and with all the same happens more or less half of the update it restarts and starts again. Unfortunately I do not have any information that the MCU, the update that the seller sent me is like the ones on the first page the kupdate.zip and the update2.bin. I send you some photos and a screenshot with the original zip they sent me.

This is that seller sendme and I always do:

PX5 upgrade method update instruction:

1. Power off, plug in the USB with the upgrade software

2. Press and hold the power button (reset button), power on

3. After displaying the Update icon, release the power button (reset button)

4. Automatic upgrade

5. Upgrade Android system software

6. Android system upgrade completes into the following interface

7. Automatically enter the MCU upgrade interface

8. MCU upgrade is complete, the system prompts the countdown to restart reboot after 5seconds and restarts after 5S

9. After rebooting, the system automatically installs the pre-installed application, with a circle symbol prompt during installation.

After the pre-installed application is installed, the status bar circle icon disappears and the entire system is considered to be upgraded!

And this is the document:

On step 9 there is a GUI picture. Do you have the same interface? If yes, most probably your device is not from this topic. In any case we'll know exactly once you disassemble the unit.
[Android Head-Units] segu45:
That is not the GUI. The problems started when I stopped hearing any sound. Then the buttons on the steering wheel started to work. At the end it restarted every moment (this is the video that I sent you). the seller sent the firmware, try to install according to the instructions and stayed in the middle, restart and from there nothing else, always enter the installation starts and half cut and start again.

Thanks for the photos. The interface is the same as in this thread.

So let's try to fix your device. Please download May 8th firmware from the first message in a thread and put kupdate.zip file to USB Stick and try to flash. If it still fails, try another USB Stick. We had the cases when the reason for the failure was in the USB Stick.
[Android Head-Units] segu45:
I tried the May, April and March, with different USB stick in the two USB outputs, with a micro-sd card in the sd and the gps. All with the same result, start the update of the system with the circle and the bars walking and more or less in half stops and the system is restarted,starting again the update and so in an infinite loop. My ideas have run out and the seller does not answer, ali-express with the dispute blames the seller. The seller at first gave me the opportunity to send the unit for change but I live in the Canary Islands, the shipping and subsequent resale the price is almost like buying a new one.
