Ha, you are not off the hook yet, Hal9k !! :cool:

There is a general (software) problem with the head unit, and I'd like to know if it's only on mine or if it's on all devices / OS flavours.

Scrollbars in ListViews don't seem to work at all

When testing with any other device (tablet/phone), the scrollbars in my app were working just fine. I had made them extra-wide for finger operation in the car.

However, on the head unit they do absolutely nothing.

I've tested if the touch signal is recorded, with some OnTouch callback which gave the correct coordinates and movements for every touch attempt. It all looks normal. But there is just no way of moving the slider - except by flinging the list, of course.

Can you confirm this for other devices? I can make a small test app if you don't have one that you can test with.

So there won't be a android 10 version or was that the imposter saying that? I'm confused.
[MTCD Software Development] illuminerdi:
Is there a guide for how to install this on a Vanku PX6 with "Android 10" (quotes because I think it's spoofed and is actually android 9)

I tried installing update from SD but it would throw an error during the install process, I assume because of the fake Android 10 and I need to downgrade

The stereo is MTCE HT v3.60:
[MTCD Software Development] marchnz:
Two options;

1 Free

2 Paid

For free options see my thread.
[MTCD Software Development] illuminerdi:
Your thread is the u

Your thread is for the Malaysk fw right? I was hoping to do the Hal9k one because I like its UI
[MTCD Software Development] Hal9k_:
There will be a version based on Android 10, but a little later.
[MTCD Software Development] Hal9k_:
I didn't pay attention to it.

I can test your test app on my devices.

Does someone know if this should work on a 1280 x 405 display?

It is a GS-CIC head display mounted on a Bnw X5 e70 with native Android 9

[MTCD Software Development] lagos911:
what about mod 5 with android 11?
[MTCD Software Development] thefunkygibbon:
these devices struggle to run android 9. are you sure you want to bog it down with android 11?!
[MTCD Software Development] JFDee:
Here is a small test program. It's really just a nonsense list.

Maybe other headunit users can try it as well.

Edit: I just noticed that scrollbar dragging does not work on my Nokia 3.2 either ...

My Samsung tablets don't have any problems,

So it's likely not a HU issue but a general Android issue. Never mind!
[MTCD Software Development] fratellos:
Since my navigation (ZNY, PX5, 4/64 GB, Android 8) did not work exactly correctly, the voices of the navigation programs (iGO, Maps, Magic Earth, Sygic)) not being mixed or switched correctly with the radio working, and the level was very low (although in factory settings I set all to 20 and radio to 2), I installed MOD4, believing that the changes promised by the author in the description, regarding exactly this issue, will solve my problem as well. Unfortunately nothing was solved !!!

Besides the fact that now VocalizerEx2 no longer works, the voices are still mixed all the time, no matter what settings I choose (?!?), and their level is still low. The author is not interested in helping me, he guided me to ask for your support. Do you have any idea what I could do, what program to install, what settings to make so I can have a functional navigation program, whose voice prompts I can hear clearly while listening to the radio ?

Thnaks in advance for every reply ! Regards !

Now I have MCU MX 3.06_1. Is there an MCU software version that does not have this problem? I think that maybe this is where my troubles come from ....
[MTCD Software Development] fratellos:
Sorry...double post :(
[MTCD Software Development] Ati_gangster:
Show us your settings from

1. Settings - Car - Navigation settings

2 Modsettings - Applikation Manager - Navigation Apps
[MTCD Software Development] fratellos:
1.Magic Earth

2.Magic Earth (no other navigation apps are checked).
[MTCD Software Development] Ati_gangster:
Show me the settings.
[MTCD Software Development] fratellos:
Thank you for your interest in my problem !
[MTCD Software Development] Ati_gangster:
Show me the settings.

Remove Magic Earth from the first list in Modsettings, only in the second.

In the first you only have to apply Google Maps.

After the settings, wait a few minutes and perform a restart. Thats it.
[MTCD Software Development] JFDee:
And again I tackled the problem after posting ... Scrollbars are obviously totally unreliable. They may be draggable or not, depending on the device (or the manufacturer).

I found it best to use "FastScrolling" which seems to be working on all devices, including headunits. The design can be somewhat customized, within limits, and the thumb size is not proportional to the list size. But it's better than nothing ...
[MTCD Software Development] fratellos:
Thank you, Ati Gangster ! Good tip ! I tried with Magic Earth and I have now loud and clear vocal instructions. I will try with more navigation apps (iGO Primo is my favorite). Regards !

Hello. I'm not expert at all of modding rooting and so on. I just tryed to upgrade my android 8.0 px5 mtce to android 10 to get usb audio output that is not available on android 8 and use my USB external dac. I bought the hal9k app,but after rebooting and selecting update file (downloaded on this thread from Google drive) I got an error. So I tryed the option "recover" to have St least temporary the android8 as previously,but the screen turned off permanently. Now I have screen black. Nothing. Is there a way to start the radio or its definitely dead? Thank you for helping a noobie

[MTCD Software Development] khaosengine:
hi guys, im messaging a seller of a PX6 headunit. Trying for compatibility of hal9k fw.

Apart from MTCE. I also need the right bluetooth module? I can't find a list of working ones, just ones that have issues. Which ones are well supported? hoping for future updates too! thank u all

Also is android 9 or 10 recommended? I plan to use ModInstaller, as the unit im looking at doesn't have sd slots..

edit: just realised SD-968 after August 2017 is good.. any other modules to look for?
[MTCD Software Development] pabloalcantara:
Recently I have sold my wifi´s car, and now we share mine.

The problem I´m having is with bluetooth.

The unit only connect to the last one connected.

For example:

I use the car, and force the BT conn with my phone. It works perfectly.

If I use it onother time, it´s auto connects perfectly.

Then my wifi use the car, but the BT connectiond didn´t auto connect with her phone, she has to force the connection.

Has anyone know how to make the HU auto connects the bluetooth ignoring who was the last user?

I have a force close message for magisk at each boot ( i read about it and aware it is probably of trying upating magisk )

I tried clear magisk stoage and disabling magisk hide and still the same case

@Hal9k_ is there a full rom with the latest ota so i can dirty flash the rom, i am a paid user but do not want to start with v4 then latest ota ( afraid to have severe issues )

Also i want to have wifi forced ON once the headunit boots up

There is a feature to turn on for known saved networks but this is the case when thr headunit is already powered on and not after boot
[MTCD Software Development] ALJ55:
So I have no speaker sound randomly on startup. I started experiencing it in Android 8 Mod 3 where when I start my car, there would be no sound and it would take several reboots to get sound. On occasion I would get sound on startup. I wiped and installed Android 9 Mod 4 without sound and no sound after upgrade. I wiped again and I had sound for a few reboots and then no sound again. Has anyone experienced this on a Seicane for Jeep Wrangler JK with amplifier PX5 MCTE_HF with both MCU 2.96 and MCU 3.3 in Android 8 Mod v3 and Android 9 Mod v4? It started happening about a year into Android 8 Mod v3?

It doesn't seem to be related to the speaker inputs. The sound is clear when its there, until it stops when the unit wakes upon starting the car. I wish I could tail -f /var/log/, but I'm not sure where that's located in Android. Likelky a rooted terminal session? It'd be nice to access that!

Is there a way to really wipe everything? I typically use settings > system > apps > wipe (or something like that). Any help much appreciated! What to look at, where to start. Thanks!
[MTCD Software Development] fratellos:
Imho it is more of a hardware problem; the pcb tracks for the sound processor/sound amplifier should be investigated...

Hi, is there another possibility to downgrade from Android 10 (PX6) to Android 9 than using Mod Installer Pro?

My collegue have a problem with WiFi and I told him to change to Hal9k mod (I have mod from almost 2 years and I love it :) ), but he os afraid that he'll pay for app from Hal and it will not working either.

Done it and its working great

Hi guys, I have seen many times, in the last posts, 2 issues that could be simple solved this way:

a) WiFi off -> you can create a simple Macrodroid macro that turns on WiFi when it's off

b) Making a voice call invocation -> I usually do that, pls try:

1. Set up your MTCdialer

2. Set up your Google assistant

3. Create a Google shortcut by mean of a simple word, such as "tel" and place as action something like "start up MTCdialer", in your language

4. When you call your shortcut saying "tel", MTCdialer will start in listening mode. Say the name you want and it's done!

So: "OK google" ; "tel": "<the name you want to call in your agenda>"

[MTCD Software Development] khaosengine:
hi I have a px6 headunit with a mtce mcu above 3.4 so im compatible.

I have a weird issue with the stock android, using zlink for wireless CarPlay, it connects to the iPhone creating a hotspot and bluetooth, it works but there is an annoying interference, buzzing sounds/ like white noise. as soon as aeroplane mode is activated, or wifi hotspot off the noise is silent. im wondering, does the hal9k include z-link for CarPlay, and if so, work all good?

The issue I have with stock rom is the wifi hotspot, then link automatically opens, when it connects to iPhone, it creates "noise" in the speakers, really annoying! my Px6 is supposedly android 10, but i'm not sure it really is.

I have installed Modinstaller and tried android 10 for Malaysk rom

I made a refund as it still have some issues and i see that Hal9k current Android 9 is better,

can i revert the process and install Android 9 recovery then Hal9k rom again @Hal9k_ ?

I have px6 and i am asking here first cause i am afraid of flashing android 9 recovery over the android 10 that it can do hard brick

Thanks in advance

edit : my unit came with factory android 9 and i was on Hal9k rom then i want to android 10

I have a PX30 with stock Android 10. If I want to install this ROM, do I first need to downgrade to stock Android 9 or is it possible to install hal9k right away?
[MTCD Software Development] noise672:
You need Recovery 9 to install Android 9.

Modinstaller can take you to Recovery 9 and then you can install A9.
[MTCD Software Development] shouk_1987:
I started from scratch back to android 9 then the free rom then all OTAs one by one

All is fine except magisk force close pop up at boot

Anybody has a solution to it ?
[MTCD Software Development] khaosengine:
quick question, for those who have px6 and stock android 10... was it worth 'downgrading' to android 9 and hal9k, im very tempted to, just wondering if I will loose anything by ditching android 10??. or is everything much better with hal9k? how is gps for example thank you!
[MTCD Software Development] noise672:
My HU came with Android 9 (May 2020).

I went from STOCK A9 to Malysk Android 9.

For me, both A9 were very bad with GPS.

I went with STOCK A10 as soon it became available June 2020. All is good.

(HCT4_PX5_10.0_ota(2020/06/24) MX/WITSON)

I will not go back to A9
[MTCD Software Development] okij:
@noise672: OK, but...

This thread is about Hal9k Android 9 rom. Did you even try it?

I'm using it on my MX/Witson head unit and it has great GPS reception. @Hal9k_ also made some improvements to the GPS driver in the Mod4.x updates.
[MTCD Software Development] noise672:
Thanks for your advice, I have no doupt Hal9k is a great rom... I read the threads all the time.

But now that I am on A10 STOCK (Plain vanilla for performance PX5) Rooted and all is good...

Thank you

N.B. Just for precision, I run HCT4_px5_10.0_ota(20201216) MX/WITSON on a LM HU

But most important is that my car was build in MUNICH and I love it.

How can we have a code lock on the screen with stock Android 10?
[MTCD Software Development] shouk_1987:
As far as i understand , you cannot downgrade to android 9 recovery if your HU came with stock android 10 recovery

My HU came with stock A9 and hence i was able to revert to A9 recovery after trying A10
[MTCD Software Development] khaosengine:
I do not understand that, I thought with ModInstaller I would be able to install the android 9 recovery and 'update' hal9k. I just have the hal9k boot screen now and it won't load :(

Hello

I got a Dasaita MAX6 with PX6 processor and DSP Board.

My problem is, that no external Soundcard works. I would like to use SPDIF to connect my Helix DSP Pro digital.

The soundcards will be detected and I can use the buttons to go forward etc. But no audio will pass the external Soundcard. Is this fixed with this custom ROM or is it depending on the Kernel?

Actually is HA2_rk3399_9.0_ota(20210301) and MTCE_HA_V3.75 installed.

Thank you in advance

[MTCD Software Development] Cavalier Condorelli:
Hi, this is an historical issue I have, I asked about it everywhere, you can follow my threads, Hal9k also answered me at the time he used to answer questions and admit the issue, I'm wondering if new android 10 mod5 version will fix it.

Are you sure you the sound card was really detected? Look at kernel log when inserting it and search if you have a similar error: "V/[ 1192.909639] snd-usb-audio: probe of 1-1.1:1.0 failed with error -1"

It seems that the failure that is received (snd-usb-audio: probe of 1-1.1:1.0 failed with error -1) prevents the regular registration of the DAC at a later time

-or-

that the system does not know to which USB device to route audio, whether bluetooth or Dac.

Furthermore the snd-usb-audio seems to not be able to manage two different audio outputs with two instances

simultaneously. In this case one on bluetooth and one on Dac.

I found this is related only to PX6, not PX5 devices.

Hello distinguished gentlemen,

I could really appreciate some support. I am trying to upgrade from Stock Android 6.0.1 to this custom ROM and I was instructed to update HCT firmware first, so I downloaded HCT_PX5_6.0(20180125) ( https://yadi.sk/d/pc2OIUsUozriFw ). However, the installation fails and it says I got a wrong image, pls see the photo attached. The thumb drive is FAT32 and update.img is the only file on it.

Any hints to what I could do would be greatly appreciated! Thank you!

[MTCD Software Development] noise672:
Hi @octibv,

You need the proper RK Recovery.

For this Hal9k Android 9 Rom, you need to be on RK Recovery 9.

Many ways to install RK Recovery:

Have a look at @marchnz [MTCD/E] Android 10 upgrade using official Free tools.

The easy solution would be Hal9k's ModInstaller Pro for some $$$.

You may need to upgrade MTCD to MTCE, not sure. Check around the threads you will find informations.

[MTCD Software Development] Angryhellfire:
Thank you for your reply. I will give a look what the log says and also if the DAC is recognized. Buttons on the module are working, but no audio.

Yesterday I upgraded to HA3 Android 10 and problem is still there. As far as I know the problem should be the Kernel and not the Android. So we have to look deeper.

This is something I found about RK3399. We could give a try...

My USB/DAC module (PCM2704) is very cheap, but before I order the Helix USB module, this must be sufficient to find the problem.

Hi, is possible to install hct7 launcher(the same of android10,with day/night mode) on this mod?
[MTCD Software Development] Cavalier Condorelli:
Same problem as mine, I confirm is a kernel issue and I suspect which is the cause.

Also Hal9k said me that on Android 10 he has the same error in the kernel logs. Look at this thread where I discuss about it in the past. PX5 USB Audio problems & finds discussion thread

there are also PX6 users with Hal9k mod in the discussion.

A developer friend of mine help me to understand which could be the issue and I sent an email to Hal9k with our thoughts... But he didn't answer.

As you will see I tried with different DAC chip hardware with same result.

But if you use UAPP (Usb Audio Player Pro) app, which came with it's own audio driver the Dac works perfectly, but only through this app, not android sounds.

Hello, i have two questions:

- I would like to desactivate the rear camera screen (and desactivation of sound) when you put the reverse gear

- I prefer a white theme for all thoses menu screen, it's much better in day light in our cars, with thoses dimmer screen

All of this was in the Hal9k Android 8 version, but was removed in this new version Android 10.

Otherwise, great addition to a already excellent changelog.

Hi I need some urgent help with this. I've paid for the updates and its all upto date. I really love the stereo as a whole, works like a charm except 2 problems.

1st being on three occasions now, after leaving the car parked overnight in the morning the stereo screen does not turn on, just the nob lights and the only way to sort it is by removing all the trim and unplugging the stereo. Anyone have a similar sort of problem?

2nd when car play is on the volume drops on the system and when a notification comes through the music stops playing and you have to go back in to the music player app.
