At least for me It is a PX6 with all OTA updates applied. I attach some fotos so one can see exactly what it is. The unit comes with a Qualcomm bluetooth 5 module.

It trades as OWTosin at Aliexpress. zLink worked on stock rom.

The app apk is in the OEM bundled persists directory, with a /lib/arm subdir which carries all the library files.

Yes, it seems to crash once after reboot, but loads when started 2nd time. It doesn't freeze.

I replaced the original HAL9K version with the 3.5.54 apk (moved into persist folder and save the original elsewhere), but no change in behaviour at all.

In my case when I start the app I can still view info, assign keys and hit the "back to car" but. But then it keeps coming to the foreground every 3-5 seconds until I force it to stop.

When I go to Info on the zlink app, it shows a code number, reading through the forums, this tells me the zLink hardware is present and detected.

Pictures of the detail attached. Hope there is some help out there from people more capable than me.

Maybe this is the case where your Headunit has supported hardware for zlink and I am not

Maybe this is why it is auto freezed after reboot

So, I tried a new iPhone. Completely reset. Unfortunatly no change. I however realized that the iPhones actually recognise he HU as Car-Play capable. The bluetooth connection as well as settings -> carplay in the iPhone show the HU bluetooth name "CAR-KIT" as carplay capable.

It is just the zlink app not going beyond "waiting"

I tried all different zlink APK versions I found, same issue with any.

The channel error many people seem to get, when you don't have the library files (or wrong ones) in /lib/arm directory.

Maybe [MENTION] [MENTION=5092263]Hal9k_[/MENTION] [/MENTION] can support here?

I am currently also on 4.02.

But I have some problems with the Rome.

1. if the screensaver was active and it is closed the launcher is in night mode although the day mode was/is active before.

2. the GPS signal is 1 minute behind so navigation is not possible

3. when a call comes in, I can't answer the call at the HU, I have to answer the call on my mobile phone.

4. Google Maps has a too loud voice output, can I set it somewhere?

5. if I let apps start automatically after booting, it behaves differently at every start, reliably it only works after a cold start, at a hot start it is different every time. In my case the apps Blitzer.de, Amigo TomTom and PCRadio are started automatically, Amigo and Blitzer.de in overlay mode. Unfortunately this does not work reliably.

6. GoogleMaps starts with every cold start, can I switch that off
[MTCD Software Development] MediaTerraneo:
I suggest you to continue looking for a dmcu.cfg for your HU- visit other threads, as this one could be not so specific.

If you really can't find a specific one for your kgl HU, consider that there is a cross compatibility between some HU. So you could try flash dmcu.img and dmcu.cfg from a COMPATIBLE HU that you are able to find. Please do it at your own risk.

Consider that I have transformed an XRC into a GS without any hardware compatibility problem and in no thread I had found that possibility documentated, although at the beginning of the transformation I suffered of a mismatch due to the different resolution ( which was then solved by uploading a dmcu.ext file - specific to set the type of the screen).

One thing I would suggest to pay attention to is the specificity of your P30, because it seems P30 has a different HW from the PX5 just as far as GPS is concerned.

Edit: Before any dmcu flashing it's a good idea to Export the dmcu.cfg from the Factory menu.

Hi, the following is a solution I have just thought, not tried to check it works, but I am really confident.

You can try to install Family Link, that is the Google parental control and treat your unit as if it was your child's phone.

Once done, you have control of your unit via network and in particular you can temporary lock the screen.:o

---------- Post added at 08:29 PM ---------- Previous post was at 08:25 PM ----------

Hi, just some details in my experience:

2. on my HU (GS PX5) the GPS is very responsive: i get accuracy 10 m (some daye ago I have placed antenna near the car roof, and tried to activate BeiDou in Southern Italy), fix is very fast, and also the speed tracked by Agama is very realistic (no delay I mean)

4. You can set the volume with Maps settings themselves, scroll down the settings

5 Also I and other persons observed a not always stable star-up

6 Some post above is reported that issue; may be you just need to set your Navigation setting /options
[MTCD Software Development] mzisman4:
Is it possible to trigger the SWC commands through other apps? Are there intents I can send via tasker?

I've had a lot of trouble with resistive buttons being detected multiple times but bought a device that can output my SWC as USB keys. This allows me to use tasker or button remappers to use the head unit exactly how I want. Detection is much more reliable but the inbuilt SWC commands seem to be more powerful. For example, "next track" won't change radio stations the way I imagine the "next" SWC command will. I'd also like to use the "mode" command to scroll through inputs.

Thanks for all your work and any help you can offer!

Hi, finally managed to get OBD/Bluetooth device to work on Mod4 (was working fine on Mod3).

Very high level instruction, you need to install:

1. Latest Mod4

2. Rockchip MTCMtcServices activate service and go to OBD settings and add any word from you OBD/Bluetooth adapter name

3. Install xposed via magisk, I have used these https://magiskroot.net/download-xposed-for-android-pie/

4. Activate all modules, reboot device, grant SU and go to bluetooth app, execute search - OBD/Bluetooth device icon becomes OBD - pair and it works!

If you need details, let me now! Good Job Hal9k
[MTCD Software Development] djdavid:
This instruction will make recognise a led Bluetooth device? ?
[MTCD Software Development] Kazliux:
It might, because mine device is not real OBD device, it is just a bluetooth dongle added to car ECU (Honda OBD1) and I needed just to pair. So I can now pair device because the icon changed to OBD instead of Phone (never paired successfully.) Once your LED device is paired, I guess you can connect to it from specific app to control it. Worth to try:cool:
[MTCD Software Development] djdavid:
Wow. I will try tomorrow.

My device is not even discovered from the HU.

I did some research and adviced that those kind of device are not allowed to pair with HU (for Chinese...).

I hope anyway this will work.

I'll let you know, thank you!
[MTCD Software Development] Kazliux:
If is not discovered, when it might be a problem... Mine was discovered but as phone only. Easier way try is to use Hal9k Mod3, go to mod settings and add OBD name fragment, restart device and then it works fine without any xposed/magisk etc hacks. Good luck:good:
[MTCD Software Development] djdavid:
Ahhh ok ok.

So before I try Mod3, thanks.

Edit: no, for mod3 I should reinstall all.

It's too long and anyway I have a PX6.

I will try with instructions for mod4.

[MENTION=2875432]Kazliux[/MENTION] My OBDlink MX BT dongle paired OK on Mod4 (just as it did on Mod3) and the OBD icon shows. I didn't do anything special, it just works. Maybe the issue is limited to certain dongles...
[MTCD Software Development] testuser103:
Hey guys, quick question, I'm very new to this section.

Since two days I own a Dasaita MAX PX6 and I would like to test the HAL9K mod.

If I flash this image and run the Mod would it be possible to switch back to the original ROM easily?

would I just need to put the original update.zip to a USB and flash or would it be more complicated?

thanks

martin
[MTCD Software Development] Kazliux:
Yes, because your dongle has OBD word in name and it works. Mod4 does not have this feature (@Hal9k_ why?:)) in Mod Settings to add more OBD names (it had in Mod3), so you need to use RockChipMyMTCService for adding BT dongle names without OBD word in default name :) but it is fine, since I use RockChipMyMTCService for front USB camera automatic switch after reverse :)

[MTCD Software Development] Nico074:
Hello everyone!

Today I mounted this ROM and it's really fantastic! :D

My Dasaita MAX6 is practically another radio! More snappy, more stable and with a very pleasant graphics. Audio also feels much better, it's much more optimized.

I would have preferred only that by clicking on the time widget (on the main screen), I could activate the screensaver. Instead, by clicking, the google clock settings appears which is useless for me. Do you know if there is a way to recall the screensaver by clicking on the clock on the main screen?

Another thing I would like to change is that the available screen savers are all in English, while I would like the day of the week to be written in Italian. Is there a way to change the screensaver language?

Thanks!

On Android 8 Hal9k v3 mod it already worked.

[MENTION=5092263]Hal9k_[/MENTION] The option to restart apps that worked before sleep is bugged for me. When I switch this option on "Google maps" will always start even if it was closed before sleep, it also doesn't open the apps that were working before sleep, feels like an auto start Google maps function.
[MTCD Software Development] Silver_:
Totally agree with you. It would be interesting if this radio widget could be changed for another one that interests us and thus not lose the night / day function, hopefully [MENTION=5092263]Hal9k_[/MENTION] will take it into account for a future release.

Hi there!

I recently upgraded my Xtrons with a PX6 board, which came with an Android 10 image preinstalled, so I am currently stuck to that firmware, as i guess i can´t "downgrade" to Android 9 based Hal9k that easy ...?

I became used to Hal9k and now miss some functions on the A10 stock firmware ;)

As I did USB-OTG flashing in MASKROM mode a couple of times with PX5 modules I could also go that way.

Is the Hal9k v4 ROM available in update.img format somewhere, so that I can directly flash it via USB-OTG cable from the computer?

Or, another possibility would be a stock PX6 Android 9 ROM in update.img format. Checked many threads and sites but could not find that. This was different on PX5, but i think PX6 is simply fairly new :)

Thank you!

Flo

---------- Post added at 02:20 PM ---------- Previous post was at 01:40 PM ----------

I have one Xtrons PB7646BP with the BC6 BT chip and second one (same model but about 1/2 year older if I remember correctly) with the SD-968 module.

The BC6 worked fine on Hal9k v4 and I recently upgraded the PX5 (2GB) board to a PX6 board from M.T.C. bought via Amazon, which came with Android 10 preinstalled - BT also works flawlessly with this firmware.

The other one with the SD-968 module had problems with Hal9k v4 as this chip - if it has too old firmware - is incompatible with the drivers included in Android 9.

I could fix that issue as described here in the FAQ section: https://xdaforums.com/android-auto/...t/rom-hal9k-mod-v4-mtcd-e-head-units-t4046361

So, there are 2 types of BT module known as problematic as stated there - but not the BC6 module:

Q: Bluetooth MD725 does not work, although everything worked in Android 6!

A: If the MD725 type 2 Bluetooth module is installed in your HU, then it will not work in Android 9. The reason is that its driver was removed from Android 9.

Q: Bluetooth SD-968 does not work, although everything worked in Android 8!

A: If the SD-968 Bluetooth module with firmware made in March 2017 or earlier is installed in your HU, then it works in Android 8, but does not work in Android 9.

Solution: replace the module driver /system/bin/sdsdk968 with the old version. Do not forget to set permissions 755 on the file.

Or replace the module with another type

I try to restore factory firmware and also no sound at all, ok, I need to put to the rubbish my HU, thanks Hal9k!
[MTCD Software Development] marchnz:
Consider that you haven't explained what steps you took to resolve the problem.

For instance did you try holding reset afterwards - or - completely disconnect the head unit from power, by either disconnecting the car battery - or disconnecting the headunit, for a period of say 5 minutes, then try again?

If nothing works after trying, have you considered that the issue is a coincidence and not software? The next questions would be, what hardware level checks have been made?
[MTCD Software Development] Stefan McSleaze:
All you just wrote i already know, i red all the text on HAL9K's Website before installing Mod4.

Honestly a suggestion i'm searching for, if you have an idea, what could be wrong? In settings or similar?

Maybe something i can solve by myself...

[MTCD Software Development] f465gt:
Hi,

did you do a MCU update before updating to v4? If yes please tell us the version before and after. Probably there is an issue with the configuration. In the factory settings (code m123456) you can set things like amplifier and other hardware stuff. If you accidentally mixed it up with a wrong MCU configuration this will stay, even if you revert to stock firmware. You can either import a dmcu.cfg in the factory settings, or check if the settings are correct.

Also, even if it sounds odd, pull the radio from the dash and check if all wires are still attached properly. Wouldn't be the first time this happened.

Hal9k :)

So to summarise, the head unit does in fact show the OBD icon when the OBD adapter is paired to the head unit, the issue is the connection keeps dropping? So, it will connect, attempt to get PIDS for the car and then the connection is lost and it will try to connect again. Sometimes, apps like Torque did actually make a successful connection, but around 1 minute later the connection was lost again. I don't understand why this is happening?
