Ok, Do you no much about this and why this is? Would it not be possible to make the hardware and software same as what a phone as so it can work with all Bluetooth devices? Thanks
[Android Head-Units] rigattoni:
Wait... I think you need to call phone and head unit as different things. The only common ground is that both use Android... but that´s it.

BT functionality is not part of the Android itself it´s provided by the MCU. For most of the hardware related functionality the system is responsible and Android is just showing the functions. So there is no possibility to get anything changed/implemented...

Could you please re-upload again. I currently have the same csn2_d_04282021_174043_v205 and I'm looking for the latest version.
[Android Head-Units] gassnico:
You can download it HERE

But I'm quite sure that is a fake Android 11 (Android 10 rebadged)

I can't be responsible in case of problem or incompatibility on your HU ! You do it at your own risk.

Best regards
[Android Head-Units] Bezzey:
Thank you mate! Where did you get that update file from?
[Android Head-Units] _SpeciaList_:
Possible also if I want to update from Android 9?
[Android Head-Units] gassnico:
It was Tina from Klyde sales team who sent it me in november!

I tried to contact her in february, but no more response !
[Android Head-Units] gassnico:
I suppose that it shoud work but in my case I was on android 10 before to proceed to update !

If everything works correctly and you're not a geek as me I recommend to stay on your version .

Each time that you update firmware you can have a bug during update or a drivers incompatibility (sometimes for a "same model" thay can use different model of bluetooth module, WiFi card, screen or ....)
[Android Head-Units] rigattoni:
To get from Android 9 to 10 is no update... it´s an upgrade.

You can´t just update to Android 10 and Klyde would never give any instructions for that, because you would grill them if somethings going wrong.

And indeed... it happens quite often that people completely overestimate themselves when upgrading the Android version to a newer one.

So if you are not sure that you exactly know what you are doing... forget about that.

If you know what you are doing... on the first page of this thread you find starting in posting #3 or #4 the instruction to upgrade.

Don´t say that we did not warn you about the possibility to get rid of a working unit...
[Android Head-Units] _SpeciaList_:
I have bugs on the android 9 version, so I just wondering if I can just upgrade to a newer version, same procedure as upgrade to the smartphone.

By the way, my device is not rooted.
[Android Head-Units] rigattoni:
No, this is no phone and needs different methods to upgrade.... written on the first page of this thread. You really need to read, not just asking. ;)

Hi guys i have a question: i recently updated the firmware using this instruction. Alle went fine but now my bluetooth isnt working anymore. I tried the latest android 9 firmware and the fake android 10 firmware. All is working exept after install exept unable to find any bluetooth devices. I choose the correct BT mode in the factory settings (FC6000TN), and restarted multiple times but cannot find any device. Tried all other BT modes (even they are not the correct module) -> same issue. In the version that came with the device (i dont know which one it was) there was no issue.

Hello,

I need some advice from you on how to flash my HU.

My starting point:

px5

4gb RAM / 32gb flash

CSN2_030202019_103040

Android 8.0.0 // Build 201903151040

Kernel 4.4.103

uboot-01_02_2019-19:00:28_M11 1024x600

I would like to upgrade to at least Android 9, or Android 10 (if it can be done without soldering).

Furthermore I would like to have GNSS with GPS+Glonass / as long as other systems can be integrated there too, gladly that too, as I can get to the GNSS antenna quite easily to replace it.

GPS+Glonass is already possible with the current antenna.

If you link me the right files, and a manual, I'll be fine - just don't want to brick it.

THX

[Android Head-Units] jgr1978:
Thank you very much gassnico!!

Can you help me for update the HU? Where do I get the "update2.bin" file? or is it not necessary?
[Android Head-Units] gassnico:
I didn't receive any update for the MCU !

But as we already said ! update firmware is a bit risky !

You could have issue with screen (resolution not recognized), bluetooth, wifi ....

You can win a bit (bug fixes) but also loose all (Head Unit )!

Which version is compatible .

I dont know which i need.

please help me
[Android Head-Units] rigattoni:
This unit is not supported in this thread, This thread is used for units with CSN2 not for MTC.

You need to search in https://xdaforums.com/f/mtcd-software-development.7379/ if there is something available for your unit.
[Android Head-Units] dkMoNe187:
Im apologized ....can u tell me in detail what I need....that's was very nice ...it's a little bit to difficult to find the right mcu....can u help me please🙈
[Android Head-Units] -gh0st-:
Hi again,

i updateted my HU successfully to the linked version of Android 8 from the first page.

But i receive GNSS without Glonass / would Glonass supported with Android 9 or 10?

My GNSS-antenna is able to receive the Glonass-System.

regards

-gh0st-
[Android Head-Units] dkMoNe187:
What do u mean with glonass?

Is that GPS or what
[Android Head-Units] -gh0st-:
Glonass is another/additional kind of a GNSS - its from russia ...

In urban areas is GPS-only sometimes bad, because of many reflections or a weak signal.

If you use more than a single GNSS it would quite easy/fast to get a 3d-fix.
[Android Head-Units] rigattoni:
Sorry, but I don´t know anything about your MCU so you need to ask in the linked forum or search for this particular unit in there.

BTW... I only would update the unit if you really want to update and your unit has issues you want to get fixed. Even if you think you found the correct update, there is a high risk that you brick your device or things do not work anymore...and that would be really bad.
[Android Head-Units] rigattoni:
This is not related to the Android version and the used antenna.

If the unit did not use GLONASS before updating the unit, you won´t be able to receive the data afterwards.

From my knowledge this is related to the used receiver on the board...
[Android Head-Units] -gh0st-:
@rigattoni

Ok, thats interessting news - i thougt, that the receiver is into the antenna and only transmitting the positioning signal to the mainunit/mainboard ...
[Android Head-Units] rigattoni:
Would be nice, but that is only half of the reality. At least the chip on the mainboard needs to be prepared to receive these data from the antenna. I still have some units laying around where I have GPS only even completely updated to Android10. Just some other units connected to the same antenna show both.
[Android Head-Units] Stooooffffel:
Upgrade from Android 8 to 9 with PX5 went great, but my Bluetooth doesn't work anymore and it doesn't find any devices.

Can I get help please?
[Android Head-Units] rigattoni:
You need to change the BT device in the settings menu.

...but tbh: This statement is not new, has been reported a couple of times with different results because the BT chip is not supported in the software. It´s a try and error and sometimes you just need to switch to another BT-stack in the settings and after reboot back to the old one and reboot.

Takes some time. If not... You need to go back to the original firmware.
[Android Head-Units] Stooooffffel:
Can you explain to me how that works? Please
[Android Head-Units] rigattoni:
Enter settings menu

Car settings

Factory settings (PIN: 126)

FUNC

Scroll down to BT-Mode

Remember the stack which is activated!!!

Switch to BC-6

Then the unit should be rebootet. Happens automatically at least after you stored the settings.

Test BT. If it does not work... go back to 1. and chose another setting and test.

I put update2.bin with the kupdate.zip when I have proceed to the update but my MCU version still the same (it's a bit strange that only 1 digit change between the 2 versions). Did you already have this kind of mismatch ?
[Android Head-Units] Stooooffffel:
everything worked great again.

Thanks !
[Android Head-Units] Cpt_Hardy:
Is there a way to replace the pre-installed version 1.2.9 of GPS Test with the current 1.6.3 Premium that I bought for my phone some time ago. I get the error "App was not installed"
[Android Head-Units] Cpt_Hardy:
is there a way to replace the internal DVD app with something else? Reason: You can only operate this app with the included remote control. But I know from other radios that you can operate it on the touchscreen. Here, for example, the DVD menu cannot be operated at all via the monitor, only via the remote control. I do not like that at all.
[Android Head-Units] Cpt_Hardy:
and one more question please: I immediately ordered a build-in 4G modem for the radio. Unfortunately it doesn't connect to the internet. The SIM card is recognized but no app can access the I-Net. There also doesn't seem to be an app to set anything else. Of course I turned off WiFi. Or does it work like with the USB surf sticks, that a W-LAN is set up that the radio has to dial into? I wouldn't really like that because I don't want WiFi in the car.
[Android Head-Units] rigattoni:
Yes...

Device needs to get rooted and with Titanium Backup you are able to remove the current version.

Did you remove the PIN from the SIM before you put that into the radio?

You need to remove the PIN before in some mobile phone, before you can use it in the car.
[Android Head-Units] Clandaries:
Hello all,

i have a question about my version that is installed.

It is a PX6 with 4x64 and DSP and fake Android 11. API is 29.

They told me they are working on real Android 12 ATM.

Can someone tell if i can install another version or is this the latest version?

And how is it possible to root Klyde devices?

I always bought MTC devices but here i am new and dont want to crash this device.

Thank you :)
[Android Head-Units] rigattoni:
I would not recommend to try something else. At least even if you would try, it would not work.

Rooting should work the same way as for the MTC* units. No difference... Use the Magisk way, otherwise the root is gone after rebooting the unit.... if we are talking about CSN2 and CSM4 units.

BTW: Your screenshot does not show the MCU version. Would be helpful to know.
[Android Head-Units] Clandaries:
OK i leave it is A10 so ok.

Here you go.
[Android Head-Units] Cpt_Hardy:
of course, this SIM perfectly works in a HuaweiE8372, there is no PIN on this SIM
[Android Head-Units] Cpt_Hardy:
further more in case there is a PIN on the SIM this is checked on boot.

I am afraid the build in 4G modem is not working at all, Will do some more tests and come back later.
[Android Head-Units] Clandaries:
This Root method worked for me.

https://xdaforums.com/t/root-for-android-10-px6-mtce.4134041/post-83072455
[Android Head-Units] rigattoni:
Then try setting a new PIN to the SIM card and try again.
[Android Head-Units] Cpt_Hardy:
the PIN on the SIM was only to get the screenshot. Meanwhile I checked the 4G modem with two sim-lock-free SIMs and it is not working at all. I am waiting for a reply from Klyde if it is possible, that I myself can remove the build-in modem and return it to them....

[Android Head-Units] gassnico:
You can try to disassembly HU and try to identify the exact model of Bluetooth board.
[Android Head-Units] rigattoni:
Ask the reseller to send a working firmware. At least:

This and the former posting is not complete.

You need to come over with the MCU version and the original firmware.

To look manually inside the unit for the BT hardware... may work but if you are sure about your BT-Stack, then you need the firmware from the reseller.
[Android Head-Units] Clandaries:
I got this link from SKYSHADOW.

They sell Klyde devices on Aliexpress.

Maybe someone wants to test?

[Android Head-Units] gassnico:
Do you have more information about these files ? it seems that is for PX6 but without iformation about version for SP or not and no information on MCU (update2.bin), it's not so interesting.

Could you ask to SKYSHADOW for more details ?
[Android Head-Units] Clandaries:
Oh yes, sorry. It is a PX6 with DSP. I have installed it. Here is a picture.

Hi good people. I need some help.

I purchased a four (4) pin car multimedia 4G LTE slot from AliExpress. When I plug it to my Klyde PX6 HU I received a blur screen and the screen got frozen.

1. I tried rebooting unit severally after removing the foreign plug but the screen returned blur.

2. I tried to flush with the software below

PX6 Firmware

Android 10.

Aug 27th 2021 202108271854 But the screen did not lit up for me to know whether it was successful despite showing process took place.​

3. Three times I plugged my laptop to one of the USB connections whiles flushing the HU on the other the screen came back with all working. But as soon us I unplug the laptop the HU goes back bricked. No light on screen and or screen touch is frozen.​

4. I tried to update the update2.bin file whiles the laptop was plugged but the screen got bricked after the update.​

I need help what else I can do to have my HU functions back. Information of my HU attached.

Regards

Felix
[Android Head-Units] Cpt_Hardy:
Hi,

does anybody uses the build in 4G modem and have some experiences with it?
[Android Head-Units] Clandaries:
I have a question.

I have installed a Klyde head unit in my moms Suzuki Vitara.

Everything is working nicely but the question is, does those units have a sleep mode like MTC devices?

When i shut down the car the head unit turns off. After starting the car the head unit starts from zero but it keeps the settings and so on.

Thans and regards.
[Android Head-Units] rigattoni:
Sure...

Settings --> Car settings -->
[Android Head-Units] Clandaries:
Thank you.

By the way, ich have written to @Hal9k_ he has thinked about to make a custom ROM for Those devices but he needs some informationb about the devices.

Here are the questions:

Can you organize the information on the compatibility of the editions of this device with each other ?

What are the hardware and firmware versions ?

How many versions of the Mod need to be made for all existing devices ?

What do you think about it? And maybe someone has the information he needs?

Regards.
[Android Head-Units] rigattoni:
I am not a friend of custom ROM so far. So may be someone else needs to dive in there. As already a couple of times mentioned... There is no need for a custom ROM. You can use anything you need and personalize the unit as you want with internal settings or just apps... without one thing which is missing:

A proper method to avoid apps like tasker to loose accessibility settings on deep sleep. But... there is a workaround for it.

What I can say:

There are different types of units.

CSN2 with digital sound proc and without. Based on PX5 or PX6, some less units based on PX30.

CSM4 with digital sound proc and without. Based on PX5 or PX6. This type is quite new and has some strange things ongoing, like having some sort of permanent button bar on the bottom and a speedometer on the left side. That means that all apps just have around 60% visibility of the app itself. At least no one needs an additional speedo on the screen if you are running a navigation software. The issue in the radio SW has already been fixed. I managed to get rid of the side bar and buttons below by freezing some apps with Titanium... but this is another story.

Both types of MCU are more or less hardware identical, just the CSM4 has a rotational screen, so I would not assume to invent time for CSM4 at this time.

CSN2 and CSM4 are completely different in using the BT, Radio and some other stuff as they are used in MTC* units. (too long ago that I used a MTC* to compare...), but at least Fcc was able to handle the radio with its CSN2 settings.

CSN2 firmware can normally be exchanged with any other CSN2 firmware based on the same API.

Root is the same procedure as for any other MTC*, even with using Magisk.
[Android Head-Units] Cpt_Hardy:
I just got an FW update from Klyde.

My old/original version is:

new verion is dated Aril 2022.

please check, if it fits to your radio and use on your own risk

kupdate.zip

1 file sent via WeTransfer, the simplest way to send your files around the world

wetransfer.com
[Android Head-Units] VAHID:
Hu

Can you share photo from launcher of this update?
[Android Head-Units] Cpt_Hardy:
will do as soon as I have made the fw update. I just received the file.

Unfortunately no instructions on how to make the update step-by-step.
[Android Head-Units] rigattoni:
No instruction needed.

Take the kupdate.zip, put it on a formatted USB stick (FAT32 formatted) and stick it into the unit. The update will be recognized after the USB has been mounted. Press ok and wait until the unit reboots automatically.

Remove the USB on rebooting, format it again or store it somewhere safe... or rename it on the USB stick as kupdate_2022_05.zip... In this case you are prepared.
[Android Head-Units] Cpt_Hardy:
can I use a SD-card or USB-Stick?

is it ok that other files are stored on the storage?

Why should I format the storage after update?
[Android Head-Units] rigattoni:
You can use both.

I always would use an own SD or stick for updates, but you can just copy the zip file on a used one with files on it.

The reason to use a single stick/SD is, that you should make sure by formatting in front is, to be safe that the SD is in a good condition and not to run into faults while updating....

To format after the update is, to make sure you don´t use it by accident and flash the radio again with the same SW.... You remember that you lose all your data on flashing the update?
[Android Head-Units] Cpt_Hardy:
does size of upgrade storage matters? I can use

64gb SD-card or

128gb USB-stick
[Android Head-Units] rigattoni:
Why don´t you just try that? :unsure:
[Android Head-Units] rigattoni:
btw...

Grabbed the KD-2000 out of the car and installed the new firmware:

It changed the system apps to a new-isher look. On top the new firmware overtakes the background from the set launcher.

I like that. In the past I always changed radio, phone and others to have a common look.... and yes still some things to do to change the buttons as I would like to have them as in my Fcc launcher. No big deal, just some work to do.
[Android Head-Units] VAHID:
Hi

How you change this?
[Android Head-Units] rigattoni:
Unzip the OEM apps, change the icons and whatever picture is needed, paste them back to the right folder.
[Android Head-Units] Cpt_Hardy:
that must look pretty nice at the end, perhaps you can post some sceeenshots.

Do you need root to do that?

So you have the latest firmware installed, which I posted before.

Did you made a backup from your old firmware?

How could I do that (have no root) or can I somewhere download the March 2022 firmware-version somewhere (just to be safe).
[Android Head-Units] rigattoni:
As long a you use the files directly from Klyde, there is no need to backup. At least my unit is 2 years old and I have a bunch of older firmware laying around... Not the one from March.

Yes to do things like I mentioned, you need root, otherwise you don't even see the needed apps.

May be in some weeks I start digging in the apps. For now I just set the unit back into the drawer.. I have enough to to beside that.

other files on the stick no not matter.

after update and on first boot system is installing 3rd party app, which lasts quite long, do not interrupt.

Here are some screenshots...

I always cancel these 3rd party app installation. No one needs Facebook and Youtube on these units.

Send the last picture with the error message to Klyde.
[Android Head-Units] Cpt_Hardy:

I guess modem is broken or perhaps wrong modem (non-Europe)?

What I have to do is to remove the modem from headunit.
