Hello! My head unit in the recent after boot cannot be use touch screen, cannot do anything, cannot use any button, even cannot use SWC buttons. But the clock still blinking. Forcing me to use the toothpick to push on the RESET button hole to hard reset. After that, everything was back to normal. It seems that after a long night and starting the car, this problem just happened. Recently, I have changed the Boot Logo so it got such issue, not before. I tried resetting the touch screen and calibrating the touch screen again in Factory Setting but it didn't work. Is the Boot Logo causing the issue? Did someone get the same issue as me? And does someone know how to fix it? Thanks for advance!!!

I am also having an issue of downgrading from Android 10 to the hal9k mod on my px6 and the reverse camera not working. It detects the reverse signal because the screen goes black but no picture. When I upgrade back to Android 10, the reverse camera works again. The strange thing is when I first downgraded to hal9k rom, the reverse camera worked for quite a while but after doing the OTA updates it stopped working, even if I install the base hal9k rom without updates. It seems that the issue is software related.
[MTCD Software Development] Wesenwesen:
Is there anything else happening here, or do I have to go down to version 4.02 now?

Sorry for the bad English, it comes over a translator.

I have been using Hal9k rom v4 for a long time and so far I have not had any problems. ROM is great!

However yesterday I tried to connect a bluetooth GPS QSTARZ 818xt, but unsuccessfully. In the bluetooth application the device is shown as OBD and when I try to pair them nothing happens.

Does anyone know how to solve the problem?

I have a xtrons unit with GS V3.40 MCU installed just before the Hal9k 4.0.1 ROM and I discovered that AF in the radio is not working anymore. I am sure that before the upgrade of the MCU and the ROM, it was working. Is the problem related to MCU or ROM? Who has the same version of my MCU, has also the same problem?

[MTCD Software Development] royalhawk2002:
I need some help. I upgraded my MCU to GS V3.40 before to switch to Hal9k 4.0.1 ROM, because the prerequisites are requiring the last MCU version. But, it seems that this MCU version has the FM Radio AF not working. Previously I was on V3.07 and was working perfectly. May I come back to the old one without problem ?
[MTCD Software Development] Ati_gangster:
Yes you can install an older MCU without problems.

Here you can find a collection of GS MCU's

When in "SWC Key" mode, in the SWC study App there is the option for short and long press setup, but changing to "Key Can" only short press is shown in the App.

It is possible to set only the "short press".

Dac Volume Control

Does volume control work with external USB Dac in this new version or is this a generally an issue with px5 units?

I'm on 4.01 and mcu 3.41

The newest one is MTCE_MX_V3.41 which is linked in this post.

MX is the same as MX2, plus it contains car logos that can be set as boot logo from factory settings.

I've installed MTCE_MX_V3.41 which runs fine with Hal9k Mod v4.

I figured this out myself. I happened to be in Bluetooth where I discovered that a BT OBD II scanner that I had used some time ago was still showing as being connected, even though I had not used it in weeks. I just manually disconnected it and the OBD icon disappeared from the status bar. Shouldn't Bluetooth automatically disconnect a device when it is no longer powered on? Maybe the Dev could look into this?
[MTCD Software Development] foggydew88:
OBD problem for me too, since the last upgrade (4.1.0 OTA-package 25.07.2020) my BT ELM327 is no longer paired, it's seen in the available devices but no paring success, it worked perfectly up to 4.0.2 OTA-package (05.04.2020) upgrade.

Yes same issue !

I recently updated the MCU to the latest (received from th seller :carnaviplayer) and till now no issue anymore.

By the same Time i updated to the latest the hall9k rom.

Perhaps the upgrade to the latest hall9k rom is the a solution but hall9k told me it wasn't a bug's rom.

It is caused by the Boot Animation Logo. I have created a Boot Animation with colors out of the 255 color format which causes the occasional error of touch failure. I replaced it with another Boot Animation and got it fixed. For 2 days, everything is still good.

Hi all, ive noticed since 4.1.0 the bootup times on my unit are significantly longer. i have tried using recovery and restoring to factory 4.1.0 thinking i t might have been some earlier release junk, but that didnt help.

I also have an issue which has only started since Android 9.0 in that, while the unit is booting, if i shift to reverse, the rear camera comes on, but then i get an actual Android software error message at times "com.microntek.backview keeps stopping"

I didnt know the actual software even had any control at that level, i thought once the 12v was detected on the rear-input camera trigger, it switched to the camera source like it was another AV input.

Either way, is there any way to disable this "Microntek.backview" ? i have searched everywhere in the mod and cant see anyware.

Also, any tips on how to speedup the bootup process?

Sound jitter issue

I just bought the mod app, and latest hal9k ota package.

Install went fine.

However, i use spotify frequently, with downloaded and streamed music.

Somehow, in android 9, there is 5-10 twitts/flickers/jitters when playing music per minute. Its so annoying its kind of unacceptable.

I get jitter in these scenarios:

- Downloaded or streamed (high quality) spotify

- youtube any video

I dont get jitters, in a2dp streamed from the phone. However, using it this way, completely defeats purpose of me getting this unit..

It was working fine in android 8 stock from december 2018. :(

I tried disabling wifi/bt. No change. Didnt try to disable gps but.. then i cant navigate with waze..

Any ideas?

I installed: HCT2_PX5_10.0_ota(20200808) (using hal9ks mod updater) and now problem is gone. and i have android 10.

The friend Hal9k Rom is definitely better in all areas but I recommend you wait for the upgrade based on Android 10 and to justify it I received a PX6 device with stock V10 one month ago and downgraded to Hal9k Mod v4 Android 9 where does not recognize the back camera although I experimented a lot with MCU changes and camera replacement may not work!

Issues installing on PX-5 MTC-D Dasaita/HA

[MENTION=5092263]Hal9k_[/MENTION]

Got the message of the OTA available, downloaded it and proceed to install, but now my unit is stuck at the initial screen of Hal9K Android Pie

- Downloaded it OK, unit restarted

- Updating process started OK (the moving-colored rings), but the last 1% took forever

- Left the process until finished, the unit restarted on Recovery, complaining that the SW release was not right for the unit (???) Sorry, should have taken a picture, but I selected "Reboot Now"

- Unit start but stucks at initial screen (Pie9 moded). After 10 minutes unit restarts. It does that for a few times and then shut-downs.

If I get into recovery I have:

Hi All,

Love the ROM, it has a lot of useful features and tweaks, thanks for that! [MENTION=5092263]Hal9k_[/MENTION]

I've been using it for a quite a while but only upgraded to the 4.1.0 last week (will download 4.2.0 when I get WiFi access again)

I was pleased to see that the dynamic parking lines now can be customised by changing the colour. I'm just wondering whether it would be possible to modify any other parameters of these (shape, distance or perimeter markings), similar to the static parking lines? my camera has such a wide view that the traces are much narrower than in reality, which results the curve not being an accurate prediction about your manoeuvrer.

I would also be interested to know whether the "door open" image, triggered by the canbus, can possibly be customised, i have a van with sliding doors in the back, the default image shows wing doors..

Thanks.

I have the same. It happened when i updated to 4.1, but i was also updating mcu to v3.56 so dunno which one actually caused it. The update to 4.2 also didn't help. Have you maybe tried the mcu v3.6?
[MTCD Software Development] Techrev9999:
Updates take too long.

I tried to install the latest update. Something went wrong, so I had to wipe. Not a problem. The big issue I have is that it has taken me about an hour just to get from 4.0.0 to being able to test the latest update again. Which may fail and knock me all the way back to 4.0.0 again. Plus, I have to dig through my emails to find my activation code. I don't even want to reinstall mod installer pro again, because the download link is deleted, and I can't remember where I saved the apk anymore. I don't mind having to pay. I like that I can support the project, and I love the product. But, the hassle - it's a bit much. Please improve the system you are using. And having updates that can jump to the latest version in one shot - even if it's for major releases or something. This is just annoying at this point.

Honestly, sitting outside in my car for hours applying 50 updates to my car stereo isn't my idea of a great afternoon.

I have found if I pair my phone and its connected, then you cannot pair anything else, like the ODB2 bluetooth car dongle etc. If you disconnect the phone (still leave it paired though) then you will be able to pair the ODB2 bluetooth dongle. You can then connect your phone again and all is fine. Unsure why it does that, but I was struggling to get anything else to pair once I had my phone paired.
