It´s easy if you read the message on the screen.

The update you try to install is for Android 10 and your unit is on Android 9. that doesn´t work like you are trying... You just can update within the current used Android API. Exactly this is readable on your screen.

If you want to upgrade to Android 10:

Follow this way if you really know what you are doing and you are able to do that on the desk, having a stable power supply available with at least 3A.

If somethings going wrong, you are a happy user with a nice metal door stopper.
[Android Head-Units] d0nni3dark0:
The problem is that I do have Android 10 already. 🙂 Here's a picture that confirms it. That's why I'm asking for help here..
[Android Head-Units] gassnico:
You probably have a fake android 10 !

try to install aida64 from google store and check android version
[Android Head-Units] d0nni3dark0:
I didn't know such thing existed.. how do I understand what Android version I actually have then?
[Android Head-Units] gassnico:
Try to install aida64 from google store and check android version
[Android Head-Units] rigattoni:
Why Aida???

AIDA is one of the most unnecessary apps on a head unit.

Install Fake Device Test and it gives all information you need.

BTW: It is not important what is written in the settings menu. Important is the used Android API, and this needs to be API level 29 if you have Android 10.

What you have is a pre-version of the UI of Android 10 on API level 28. That´s done by most sellers... unfortunately.
[Android Head-Units] d0nni3dark0:
That's very annoying man! Thanks for the advice, I installed the app and it confirmed my px5 has Android 9.

Does this mean that it's not recommended to upgrade to Android 10? I saw the first post and I'd be in trouble if I had to remove the unit for troubleshooting on a table. What would be the pro/cons of upgrading for a PX5 system?
[Android Head-Units] rigattoni:
It is common practice that they implement a new UI and sell them as an upgrade. Most of the units in the wild are fake Android versions. Mostly propagated as Android 9.1 or 10.1 or something like that.

Well... it depends if this is recommended to upgrade, or not.

If you don´t have any issues with the unit, just keep it as is.

For UPGRADE to Android 10, I really would do that on the table and not in car... and mostly you have to open the unit for shortening these both contacts on the board in there. How do you handle such work in the car, not having the right length of cable, sitting in front of a partially removed unit... No way...

You need to have a right USB male/male cable and you should not be frighten to brick the unit. That should not happen, but it can happen.

If you really want to upgrade... just follow the link I posted yesterday in #3. Good luck however you decide.
[Android Head-Units] gassnico:
I received a new firmware and MCU from klyde for my heda unit !

I share it but don't forget, that is not without risk and as rigattoni say, if you haven't any bug you probably don't need to update your head unit.

On my side, I'm a old geek and know the risk of brick the system.

This update is specific for my configuration PX6 64GB with DSP and screen 1024x600L

Build version : 202212091124

MCU version : CSN2_D_03122022_103312_V102

Android version : 12

Files sent by Klyde team are available HERE --> no more available

You can find a copy HERE until 27/01/2023

I performed the update and it seems to works but I didn't used it enough for say that is free of bug !

Best regards

Nicolas

Hi, anybody knows 6-pin sim connector pin-out in px6 model? H conector.

I buy one in aliexpress beacause old was broken and my wife throw away, but when I connects the fuse blows.
[Android Head-Units] marchnz:
One could always spam the forums with the same question, hoping someone knows :)

Ask seller - what do they say
[Android Head-Units] rigattoni:
I really don´t know why you posted this question in this thread?

This has nothing to do with Klyde and nothing to do with the MCU´s handled in this thread.

So please stop spamming the forum with one and the same question. Get familiar with your unit and aks in a new thread with the needed information there are:

Which MCU is in use?

Which Android version is in use?

What is the type of CPU used in this unit?

Nevertheless: Read the last sentence of marchnz... Ask the seller about a new harness,
[Android Head-Units] SeroS89Rus:
Hello! Can you add screenshots of this firmware and check if it is real android 12? Program Fake Device Test view version API
[Android Head-Units] gassnico:
Which kind of screenshot ? I already attached system info screenshot !

Personally I use agama car launcher and not the default one !

Herewith AIDA screenshot with API level : 31

I will try Fake Device Test and take you informed !

I confirm that is a fake android 12 ! API version read by Fake Device Test is 29 --> Android 10

I will send a message to my klyde contact !

[Android Head-Units] gassnico:
I have a WQ_RF210 bluetooth module on my PX6 and the ELM327 works fine !

Are you sure that the OBDII is not already connected to your phone for example ?

best regards
[Android Head-Units] rigattoni:
I knew this already.

Android 12 is coming later as far as I got the message. It´s just the UI from the upcoming Android 12

...and as I always write prayer wheel-like, AIDA is not usable on these units.

They just use the written Android version, instead of checking the Android API. That´s a real bug since years now and they don´t fix it.

All you guys need is this Fake Device Test app, available for free in the market.

You can do your checks for CPU, memory and a lot more.

Well... Have you already bonded your phone with the unit?

Check the PIN which is on Klyde units always 0000.

Check the PIN which is needed for your OBD device (most probably 1234).

If both PINs are the same, okay... if not, change the standard PIN on the head unit.

As you can see in the video, the PIN is set for the OBD to 1234 and the head unit shows 0000.

Change the head unit to the PIN used on the OBD and you will get it working.

...and as always: Connect the OBD BEFORE you connect your phone with the head unit!
[Android Head-Units] erfanoabdi:
may i ask whats your device mcu and firmware version?

i tried any possible pin number, nothing helped..

But yeah no phone connected at all

btw do you know if there's a new update for my device?

Current version: CSN2_D_04282021_174043_V205
[Android Head-Units] gassnico:
As you can see on my previous messages my MCU is : CSN2_D_03122022_103312_V102

and build version : 202212091124

But my ELM327 was working fine with all previous version

Best regards
[Android Head-Units] rigattoni:
There are not a number of different PINs to choose from.

You need to check the OBD device for its PIN and have to set the same number as standard in the head unit.

About updates for your unit... Get in contact with Klyde and they will send you the newest.
[Android Head-Units] erfanoabdi:
my old px3 headunit just works with 1234, i tried both 0000 and 1234, none of them helped
[Android Head-Units] rigattoni:
One page back, in posting 2136 there is a link to a fake Android 12 version, but at least the newest you can get.

Just use the firmware. With the MCU, I would be carefully and ask the guy about his unit... screen size and stuff.
[Android Head-Units] erfanoabdi:
Yeah but that's 102, mine is v205
[Android Head-Units] rigattoni:
That´s why I wrote to use the firmware only, not the MCU update.
[Android Head-Units] erfanoabdi:
thanks so i'll just do the firmware update and see how it goes :D
[Android Head-Units] erfanoabdi:
updated but unfortunate it wiped my userdata and i lost my zlink activation.

no luck on obd2 detection too

uuh i hate my life, why i didn't buy MTCE :((

this klyde units are broken in every possible way

Update:

I've realized Bluetooth is controlled by some binary called gocsdk

Bluetooth data goes to /data/goc

I was able to manually move my obd device to paired devices on the database

But still getting error 07 on connection..
[Android Head-Units] rigattoni:
I can´t blame Klyde in any way...

I have in use 2 CSN2 one 10" and a 7" unit, CSM4 with a 12.2" and another C7PA with a 12.8" screen.

All are working fine also with a cheapo OBD dongle for 6 USD, buyed at Ali. So I expect that the dongle is not compatible with this new unit... and you would most probably have the same issue with any actual MTC* unit

I would check just another cheap OBD dongle...

Well... Updating the unit always deletes the user data, that´s quite normal for nearly all units. Only my C7PA is able to keep the data.

Get in contact with Klyde and tell them about the missing activation for zlink.
[Android Head-Units] erfanoabdi:
well actually as i said my obd works perfectly fine with px3 mtcd unit

thanks, i'll contact them
[Android Head-Units] rigattoni:
Older PX3 are completely different as the new PX5/6 units.
[Android Head-Units] erfanoabdi:
anyway do you know if its possible to order MTCE base board and replace it?

i mean.. is it gonna be compatible? csn2 board has 2 more connectors by the looks of it
[Android Head-Units] rigattoni:
I don´t know anyone selling MTCE boards, but you can order PX6 boards on Ali.

If you really want to switch to a more or less outdated MTC* unit... To buy a new radio would be cheaper as the way of changing the boards. You still have to take care of the screen... Can be the same, but there is no guaranty.

Nevertheless...

Get a 10 bucks OBD unit and use the CSN2. It´s a good unit and you will have no issues for years. Just hanging on a former working OBD stick is just a stupid decision.
[Android Head-Units] erfanoabdi:
Thanks man, so i'll try a new dongle first.
[Android Head-Units] Hot-P-Tgz:
Hey everybody

I purchased a Kunfine head unit for my 2013 Prius - everything works fine, but as many here I was wondering if there is a way to update Android (or find a way to use Android Auto, really).

I had a search on the forum / thread and although I managed to identify it's a CSN2, I wasn't able to find the rest of the MCU version anywhere.

What can I do? Is it possible to root / upgrade? What files should I use?

Thanks for your help!

(I attached the pictures I took from the unit "About machine" page. Thanks again!)
[Android Head-Units] rigattoni:
Just read the first page of this thread. All visible there.
[Android Head-Units] Hot-P-Tgz:
Hi there

thanks, it's just that I'm not sure of what firmware I should use. I'd like to avoid bricking my unit :-) Shall I use one of the following?

Android 10.

Mar 31st 2021 202103310921

Mar 23rd 2021 202103231402 with Erisin launcher

Jan 4th 2021 202101041604 + MCU CSN2_D_1152020_114303

Apologies and thanks :-)
[Android Head-Units] rigattoni:
Jan 4th 2021 202101041604 + MCU CSN2_D_1152020_114303 (n)

Mar 31st 2021 202103310921(y)

I would ask the seller for further updates after you upgraded to Android 10.

But... There is always a chance to brick the unit. As always: Upgrading a unit and root is done on own risk.
[Android Head-Units] Hot-P-Tgz:
Thanks for your help. I bought this unit on Amazon and the seller has already replied to another user that they're not supporting any update - which is fair enough I guess.

I'll read on how to do the flashing and I'll keep you posted :-)
[Android Head-Units] Hot-P-Tgz:
Out of curiosity, is there a way to get Android Auto to work on my PX5 Android 9 unit?

Do I need to upgrade to Android 10?

Thanks
[Android Head-Units] rigattoni:
You should have CarbitLink on your unit.
[Android Head-Units] Hot-P-Tgz:
Thanks for your reply and apologies, I'm a supernoob.

What's that? And what does it do?
[Android Head-Units] rigattoni:
That´s another solution instead of using Android Auto... and by the way... Why using Android Auto if your unit is fast enough to use any software on the unit instead of digging around with a messy Android Auto.

Keep in mind: Android Auto was developed to be used on OEM cars wich don´t have the ability to use other software as the one the OEM installed.
[Android Head-Units] Hot-P-Tgz:
Yeah, I really have no idea of what I'm talking about.

In a nutshell I just want Spotify to work :-D

It seems like Head unit reloader may do the trick, I found that in another post on this site.

I'll give that a go :-)
[Android Head-Units] rigattoni:
Then just install Spotify on your head unit...
[Android Head-Units] paralias7:
Hello. I have a CSN2_D_********_****** unit with PX5 chip. Android 10. I have problems with the car's original volume knob. It is working very badly. Also the built-in radio app does not support 3 bands of fm with 6 stations. If i upgrade to the latest android version, will all these be solved? Do i need to unplug the unit for the upgrade or a laptop? Or just the downloaded file within a usb? i am a little bit confused. Any help here?
[Android Head-Units] rigattoni:
Which MCU and which exact firmware is installed now?

Which car and which original volume knob?

Never heard of your FM-issue.
[Android Head-Units] paralias7:
The car is citroen c4 ii (2014). I mean the volume wheel which we turn to increase or decrease volume.

The last picture was taken before i install the new head unit but the volume knob remains.

As for the radio stations i mean the most of the radio players have 18 memory stations with 6 buttons. We have the first 6, and when we press band button it then goes to the next 6 memory etc etc. Mine doesn't have this. It has one touch button( on the screen) that show all 18 stations to choose, and i am wondering if a newer version of android 10 if it has different radio player.
[Android Head-Units] rigattoni:
Have you tried to swipe to the side?

There are 18 stations...

Nevertheless, You should update the MCU and the firmware.

Before downloading, install "Fake Device Test" app and check if this is a real Android 10 or not. There was a short period, where we got a fake Android 10.

You can do the update within the same Android version in the car. If you find out that it is Android 9 instead, and you want to upgrade to a real Android 10, you should remove it from the car and do that on bench with a good power supply, to prevent power outage.
[Android Head-Units] paralias7:
Yes i tried to swipe but with no luck. Very bad fm radio app. I tried NavRadio+ but it doesn't support my head unit.

Yes i will install the "fake device test" app because if it is android 9, i will not try to do anything more. I am afraid that i will destroy it. Also i don't have the equipment for that. I hope i will be lucky and the test shows that is real android 10. If it is real android 10 what file should i download for android and mcu?
[Android Head-Units] rigattoni:
If it´s Android 10, you can download the latest firmware for PX5

MCU would be the latest one with CSN2_D_*** If you use a different one you would get no sound out of it. Can be repaired by installing the right one, but if you can prevent that, it would make your life easier.

Check the first posting for MCU and firmware...
[Android Head-Units] paralias7:
If i am correct i should use one of these three files? Only the 3rd has mcu?
[Android Head-Units] rigattoni:
Use the one from March 31st as firmware and the MCU out of the third link.

Update procedure is written in posting 2
[Android Head-Units] paralias7:
Ok thank you very much for the helpful information. Now the other thing that scares me is that if my device bricks, i dont have buttons on it to do the necessary steps to unbrick it.....
[Android Head-Units] rigattoni:
But you have a micro-switch on your unit. There is a small hole marked with RST to be used instead. Read the full second posting. ;)
[Android Head-Units] paralias7:
Once again you helped me a lot. Actually i did see the reset hole. I will return tomorrow with the results of the "fake device test".

Thanks again!!! (y)(y)(y):):):)
[Android Head-Units] paralias7:
I did the "fake device test" and the results are these....

So i am good to go with the easy method of the update?

Also one more question. I downloaded the first file as you told me. I see that the second file mentions that has erisin launcher but its older. Does this mean that the first file which is newer also has erisin launcher?
[Android Head-Units] Clandaries:
Does someone know any updates for Fake A11 devices?

It is from the seller Skyshadow: https://de.aliexpress.com/item/3297..._main.104.21ef5c5fjpfnZc&gatewayAdapt=glo2deu

PX6 and DSP.

The head unit does not stay in stand by it always start from 0 but keeps settings, so i think it is a false in the firmware?

Maybe it is possible to fix.

Thank you
[Android Head-Units] rigattoni:
Yes!

No... The first one is the firmware you should use and it has the Klyde launcher. From the 3rd link you should use the MCU file and send the firmware to the trash. This is the oldest one and has still issues.
[Android Head-Units] rigattoni:
Did you get in contact with the seller? He should be able to send you the latest version...

If not, just install the latest Android 10 version. As this is a fake Android 11, you can just install Android 10 on it.
[Android Head-Units] paralias7:
Yes i understood the difference between android and mcu files. What i said is, we have 3 files with 3 dates right? From the 3rd i only take the mcu. Ok with that. Now the second one in the middle says that has erisin launcher. And i am asking... Does the first one has erisin launcher too?

I am asking that because as i said my built in radio tuner app does not support memory stations 3x6=18 as we know it. And i am wondering if erisin launcher has that thing. Also how do i know what launcher my head unit has?
[Android Head-Units] rigattoni:
You can try it and if it is not as you want, just flash the other one...
[Android Head-Units] paralias7:
I'll do that! Thank you very much. I'll repost with the results of the upgrade!!
[Android Head-Units] paralias7:
Everything worked out in the end!! Thanks again for your help!! Here's a photo of the unit after the update...
[Android Head-Units] lew26:
A lot of the apps require an internet connection to fully function. Traffic, weather, stream music etc.

Not all HU include a cellular modem. Some people would rather not pay a monthly fee for a data plan for their HU.

Hot Spot isn't included with many plans.

_yuzo_ - My gps receiver is on the top of my dash with no obstruction. It hasn't change. I'll have to check the wiring to make sure it hasn't come loose but doubtful. When I use the stock "GPS FIX" app, it normally sees 13-14 satellites but can't get a lock. The SNR is the about the same as my Note 8 which easily locks. I'll try a later firmware.

Q? Is there lock screen option on the new fw?

Hi guys, I just got myself a new android unit from skyshadow.

It's running on a android 9.0, I would like to ask if i can just install the firmwares here ?

So far it is a positive experience except for few issues

1. Can't get my OBD2 to connect

2. When my healights turn on and off, sometimes the USB sticks unmount and mounts itself...which is irritating when you playing some music

3.Modem sticks will not connect if you restart the car without restarting the unit, therefore i will need to connect to a wifi/hotspot first and disconnect it, and the unit will auto connect back to the modem.

would be good to know if anyone else experience this and have a fix for it.

Are there any instructions for this apk? Is this safe to use or will it install some kind of keylogger to the ether?

---------- Post added at 12:12 PM ---------- Previous post was at 12:07 PM ----------

Good to know, I installed the fw but not the MCU. I'm still having problems with a very slow GPS lock, especially after it looses the sat in the cities. Using "GPS Test" I can see that it can view over 12-15 sats but just can't get a lock on them so it looks to be a software issue. I am also going to try to root the unit so I can update the gps.conf file.

Root APK is tested and safe.

Root the device:

1- Install the apk

2- Choose "root shell comands"

3- Press "Root"

4- That's all.

NOT UPDATE THE SU APK OR FILES, if its are updated in the next reboot of device you have a NICE BOOTLOOP
[Android Head-Units] _yuzo_:
Your MCU is CSN2_D, seems like you have DSP module installed. Please do NOT try to update firmware for now. MCU is a bit different and you can receive the unit without the sound and the android version is not the same. If you have photos of internals that would be useful for us.

Great. Thanks you for the details. It would be useful for other people.

Thanks! It looks like the units from thread, so most probably, we'll find the way to flash android 9 to our units. Could you also remove the shield from the main-board and show it in more details. If you have some spare time, I'd like to ask you to make a dump of recovery/system partition of your unit.

Thanks! Yes, SU apk should not be updated.
