[MTCD Software Development] tonycajjo:
If you installed the Hal9K Rom it is included as a separate "settings" app. The wording for what is actually the Auto Start is a bit tricky, I think it's just in the General Settings and says Allow Apps after Restart? I can look it up again later. But it works, i recently started using it to load my i-bus app automatically and it works as intended.
[MTCD Software Development] GoNzCiD:
Hi, I'm trying to install the rom but always return the same error: "Signature verification failed". after 371 seconds. I have tryed two usb memories and from SD with same result.

The unit is a PX3 upgraded to PX5 board and I have a android 8 system.

How can I install it?
[MTCD Software Development] GoNzCiD:
I have downloaded the file again and it's flashing
[MTCD Software Development] GoNzCiD:
I have been testing the ROM over a PX3 unit upgraded with a PX5 board. The performace is OK, the wifi is OK but I have an issue with the Bluetooth.

The Bluetooth settings are ok, it appears named as CAR-KIT and default pass 1234. But never find any device. Since mobile (I have tested 2) hu is discovered as CAR-KIT but always throws an error while trying to pair.

I have seen any other similar problems but usually wifi & BT are broken. In my case wifi is ok and BT is recognized but don't work.

My wifi & BT chip is rtl8723bu, as I can read it's configured as MD725.

I have seen any solution like https://xdaforums.com/android-auto/.../px5-fix-md725-type-2-bluetooth-oreo-t3865670 or any other, but I need to be root. How I can root the hu with this rom?

Thanks a lot.

Is it possible to create the zip from my stock eonon?
[MTCD Software Development] jogobelo:
Hi, switch the module settings to: WQ_BC6, and it will be OK.
[MTCD Software Development] nic2k:
If your chip is rtl8723bu then MD725 is correct. Have you tried connecting bluetooth with a different phone? I have had issues with devices not wanting to pair with my phone but work just fine with a friends phone.
[MTCD Software Development] Haebbe:
This call button on the right side is available in the other submenus of the Bluetooth app but not in the menu with last/missed and dialed calls.

I can also add a video to prove this.

I definitely found no possibility to call back the missed numbers which is a important feature and very useful.

Can it please be fixed ?

I have tested with a Huawei and a xiaomi without luck... I have a odb bt dongle and Hu doesn't discover when I try to refresh...

I have notice than when phone is trying to pair the wifi signal is too weak and in sometime completely lost. After the error it is restored automatically.
[MTCD Software Development] Hal9k_:
Usually a launcher works best with its widgets. Apk is located in the same folder as the launcher.

The problems that you describe are most likely related to hardware. Possible reasons:

Overheat,

Malfunction of touchscreen,

Phantom clicks on touchscreen or steering wheel buttons or panel keys.

The PX6 is a completely different device requiring its own firmware.

Train this button again. This has already been discussed.

The device cannot successfully pass the SafetyNet test even with stock firmware. Are you sure it can pass it with the new Magisk?

I wonder where you got it? :D

I do not have that.

I can say that the MCU has nothing to do with it.

Try to get logs.

Root is already built into Mod.

Check the type of your BT module.

For this you need to sell this device and buy MTCE.

[MTCD Software Development] theredbaron1834:
I don't have any idea if it works for head units, but the only way my phone could pass safetynet was with magisk and said module. However, I don't know the ins and outs of magisk, or how you got it in this rom. So its working is unknown.
[MTCD Software Development] ali-e90:
I got over-zealous and installed Hal9k's build already... lol

BUT, i did request updated firmware files (MCU and System) from Eonon tech support, so maybe we'll get something from them. Will post when I hear back.
[MTCD Software Development] omariscal1019:
Thanks hopefully
[MTCD Software Development] 10thDmenxn:
I was starting to suspect as much, and returned the unit. I will NEVER buy an Eonon or Xtrons again. I now have a Dasaita MAX6 PX6 and will wait for futher development for this chip. Thanks.
[MTCD Software Development] Keiuran:
I have this unit that's been giving me a decent bit of trouble.

First off, my steering wheel buttons for call and hang up do not function at all (I believe it is a hardware issue based on the wiring diagrams).

More importantly, I cannot get the "VoiceControl" app to function and I have no idea why it won't work. I have the optional Parrot FC6000T Bluetooth module installed in the radio and audio and calls function fine but I can't start them handsfree.

I tried to work around this by having the "Ok Google" or "Hey Google" work, but for some reason when I try to enable this feature it gets blocked from activating. When I push option to turn it on it looks like it goes, Google says there's already a voice recording, but then it's grayed out still.

Trying to get around this, I tried changing the keys on the panel control module (the little one in the center that comes with the radio) to activate the Google Voice app on a long press, but any attempt to open an App through changing the key settings just says "fail!".

I'm at an utter loss on how to get this thing to be handsfree. I feel like I'm locked out of doing anything I need to make this radio work how I would like.

Will this ROM help me out? I'm not really sure where to begin learning about these units in detail so I can get it work better. Eventually I would like to add an amp and new speakers to the vehicle, but if the headunit is this frustrating I'm not sure what to do.
[MTCD Software Development] tribalfs:
[MENTION=5092263]Hal9k_[/MENTION]

Yes, I am able to pass safetynet on your ROM using EdXposed module. The problem with Magisk v18 is just that the magiskhide settings not sticking on the selected apps.

Really helpful if you can give us an boot.img with Magisk v19 or push an OTA for the magisk V19* update.

Edit: Please see video here: https://youtu.be/g9Dq-GAOUXI

Thank you.

Update: I found one app that only passes safetynet check when not connected to the internet. Otherwise, it fails.

My headunit consistently passed safetynet using the built-in safetynet checker in magisk manager, either connected to the internet or not. Also tried several root and safetynet checker apps from play store, it passed even when connected to internet. I understand that magisk v19 may address this issue of some apps that checks safetynet beyond the safetynet api.
[MTCD Software Development] Nosstrom:
I don’t know for you but I got serious trouble with WiFi reception and sometimes stops downloading stuff it’s a little bit unstable and works perfect if I turn the WiFi off and on again .the stock rom had better WiFi reception and the signal was strong without problems. The radio stop working if I press the return button , on stock was keep playing no matter what. Can’t install new launcher apk , and I think that on stock the sound was better I don’t know if it’s viper but I don’t see any change no matter if switch on or off. Magisk doesn’t update to latest version says failed unpacking something like that .

Any help would be great . Thank u
[MTCD Software Development] Silver_:
Suddenly something strange is happening to me with the MTCDialer application (integrated into this rom). Before the sound of the radio muted me but I began to fail and now, the first time I start it does not mute the radio, and yet I start it again and I do the mute perfectly. I do not understand why this has happened, I suspect several things: that I have touched some MOD settings menu, that the Google app has been updated and that's why it fails now, or that MTCDialer has stopped being the default app.

Trouble installing Hal9k

Hello, and thank you for your effort. Looks easy to do it, but i am an absolute noob on this stuff.

I have tried to install Hal9k to my Joying with Android 8.0.0 and the PX5, but at the start it goes wrong already.

I have loaded Modinstaller.apk to my HU, but when i let it run (pressing the Install-button), it says "Please wait", and stays in that exact step. 20 minutes, 30 minutes, 1 hour..... Nothing changes. Luckily one touch on the return button in the top of the screen brings me back to the original state.

Where am i going wrong? :confused:
[MTCD Software Development] Mlkfahl:
how did you resolve this, my unit did the same thing and now I cant get into recovery, just a black screen with some words

I had Malaysk Oreo 8 rom installed and I tried upgrading to your rom as described in post#1 however I had a problem where I got stuck in a boot loop after partial install with hanging on your Hal9 logo. I couldnt get back into recovery no matter what I tried. I went the otg jig route and was able to flash your sdupdate.img, and after that I had problems getting recovery to see my usb drive, so i tried an sd card with your update.zip, that didnt work either, so I did a full format of the sd card and put the update.zip back on again and its now working.

So I've been running Hal9k for a solid 5 months now and never had any problem with it until recently I was putting my PS2 slim in my car and tried the AV in app, it's practically unusable.

Is there a way to change the speaker setting in viper4android? With hal9k rom viper4android has set the output of the car speaker to "speaker", which is correct but not ideal. It would be much better if it would be "headphones", because this section has way more settings. I couldn't find a way to force viper4android to do this.

[MTCD Software Development] ali-e90:
A member in another v4a thread said that despite my driver version being 2.5.0.4, my app appears to be v2.7, and they dropped support for lock effect.

I got v4a via this hal9k rom, is there an easy way to downgrade v4a to v2.5?
[MTCD Software Development] Ammby:
Not Driver version, App version
[MTCD Software Development] Ammby:
1. Uninstall viper4android

2. delete /oem/bundled_uninstall_back-app/ViPER4Android/ViPER4Android.apk

3 install attached version. Choose "recommended" if it asks.

In this version you can choose "lock effect mode" in settings. Choose "Headset" and you have all the v4a benefits.

Hi [MENTION=472138]hal9k[/MENTION] and others...

I have 2 other cars with Hal9k rom running (PX3 and PX5).

Now have another car in my car park (Volvo XC90) and it was hard to find a good Android unit for it for a fair price.

Ended up with a unit that has 2GB ram and this CPU: MT8227L Quad-core 1.3-1.5GHzCortex-A7Processor (manufacturer is Seicane).

After some Google search I saw that some people still updated their unit with this Rom (not exactly the same HU).

Can someone confirm that it works? I don't like the original firmware.

And can someone also confrim that after installing this ROM I can still acces the extremly full car/canbus settings (much more the I have on my other 2 units).

Thanks guys!
