What you have to do is install the recovery of android 9, because you are going to change from 8 to 9. Next step is to install a Stock version of android 9, no matter dasaita or MX from the same recovery. Once installed, put the Mod4 of Halk9 in a pen-drive and install as if it were an update from the settings menu. This is the safest way to avoid signature problems. I put a link with the recover of version 9. You can follow the steps of the pdf that the other partner has passed you.

Where can I find stock android 9? In archive above?

So what I have to do

Install bootcard.img from thah package, and next install sd update?

After two years on a PX5 with your Mod I got my PX6 on thurday and installed v4 and it's working like a charm.

Thanks for all of your hard work. The opportunity to get OTA updates and support you at the same time is a very fair strategy and it will insure that you can do further development and improvement.

Thanks.

Hi all, I've a little issue with steering wheel and HU commands, I'll try to explain: After ROM install, on my PX6 (firstly 4.0, then 4.01 OTA updated) when i open Sygic, both steering wheel and Head unit commands doesn't work. Only volume on steering/knob works. Forward or reverse commands used to control spotify don't work. Outside Sygic, all commands works with any problem. Does nobody has this same issue? Solution?
[MTCD Software Development] klain13:
Hey guys what kind of launcher do you use? Would you like to post the pictures?
[MTCD Software Development] okij:
It's a problem of Sygic. It captures steering wheel and media key presses, although there is no apparent good reason for it.

The only solution is nagging Sygic support (i.e. support@sygic.com and urgentsupport@sygic.com) so that they at least add an option to turn off this bad behaviour in Sygic settings, plus leaving a 1-star review with description of this problem at Play Store.

I already did so some days ago, and when you and hopefully others will follow, hopefully they will listen and react.
[MTCD Software Development] vadmajom:
I have the same problem with sygic and poweramp. But intreresting that the "factory" music app reacts to the wheel key buttons under sygic :confused:

Just had the chance to check obd11 devices so not one out of 10 will sink with device. They all sink on the cell. So is a firmware issue. All of them did connect in 8 so between 8-9 something broken. I down load the rockchip apk not help. Hopefully next update resolve it or I have to back to 8 for this. Also lots of apk still won't work with this andriod 9 so seems some of the Google required files not installed so this why alot of playstore apk say incompatible or not shown.

Is there a way to update Android 8.1 to 9 on the PX30 without modinstaller?

There is for the PX5 and it worked great for me.
[MTCD Software Development] orbter:
So far I found those annoying issues:

launcher does not allow to change default home screen

GPS still lags a lot (even with advanced settings off, as suggested here)

Turning dark/light mode off does not work (it ignores dev setting to always on/off or clock dependant)

Can't make other music player as default. It wont start playback after HU turns on no matter what I set in Hal settings

Radio does not store RDS names on memory buttons, but frequency only

FYI : I could change the default home "wallpaper" by going to an image app and chosing the "set as wallpaper" feature.

I changed the default launcher to agama launcher without problem.

All my 5 obd2 adapters failed to connect, despite the "obd" logo displayed next to the device name in the BT settings of android.

Today I receive a obdlink sx (usb), I hope it will work. Someone said it works, but he was on another rom (I can't tell which one).
[MTCD Software Development] royalhawk2002:
I discovered that is not possible to remove the OBD adapter from the list of the bluetooth devices. This prevents to recouple it , i.e. after PIN change.

My OBD adapter is working well with Torque and AlfaOBD on my Note 9 with Android 10. It was working perfectly with the Hal9k previous ROM Android 8, but is working only with Torque on the actual ROM. AlfaOBD is connecting and after a while is loosing connection. I hope that [MENTION=5092263]Hal9k_[/MENTION] will solve the problem.

Finally got an OBD2 adapter working

Cross topic Dasaita Max6 PX6. Finally I found a working OBD2 adapter. ODBLink SX USB is working flawlessly and plug and play. I'm using it with Hybrid Assistant. Here is a video of my boot sequence to get all my favorite apps working at boot (I used tasker) :

https://streamable.com/v0o1o

Please note that the global delay (1mn) is due to the wifi tethering delay, not the PX6 speed :

- the hu connects to the phone using BT

- the smartphone activates tethering at this moment

- the hu connects to the wifi

- tasker launches camsam (radar app) and spotify. Spotify don't behave adequately without internet, it loses it's active playlist.

At the end of the boot I can customize tasker so that I stay on Hybrid Assistant or rather go back the Agama home. Here is the agama look :

[MTCD Software Development] dafunky:
Hybrid assistant is dedicated to some Japanese hybrid cars based on the toyota HSD engine. You can search more on YouTube or google play store.

You can find the "obdlink sx" on Amazon or eBay using this name. As said before is it usb, I plugged it on one of the three usb ports available. It works on the other ports too.
[MTCD Software Development] tagallo:
Guys one question, if I add apps to the list “do not stop when sleep”, does that increase my standby power consumption?

I’m leaving my HU in sleep always (no turn off). I have measured the power consumption when the car is off and it looks okay. However I’m curious if adding FCC launcher and Spotify to the list will increase the power.
[MTCD Software Development] _snIP3r_:
hi all!

today i encountered a massive bluetooth problem. i cannot connect to my former paired smartphone (nokia 7 plus, android 10). the smartphone is shown in the paired devices but if i try to connect i get the message from smartphone "cannot communicate with car-kit". deleting the pairing (on bothe sides) nor rebooting the HU does solve the problem.

has anyone encountered the same? any suggestions?

thx

snIP3r
[MTCD Software Development] okij:
It doesn't increase standby power consumption, because it only lets the whitelisted apps stay in RAM, which keeps powered in standby anyway.

The apps aren't running during standby and the deep sleep times of the CPU stay the same.
[MTCD Software Development] foggydew88:
Yep, same for me, GPS fix is a pair of minutes long and after that is laggy, in any settings conditions.

Anyway thanks to Hal for his work.
[MTCD Software Development] nagibo77:
yes same to me too, the GPS still lags a lot.
[MTCD Software Development] shouk_1987:
Sorry but bear my ignorance

So you are connecting the obd interface to the OBD port and then under the dashboard you are connecting the other end to a free usb port from the headunit ?

What app do you use on the headunit to see the car's status and what info you can read/modify?

Is the below from amazon is the same device that yoy have ?

https://www.amazon.com/ScanTool-OBD...=obdlink+sx+usb+android&qid=1583931476&sr=8-3
[MTCD Software Development] tagallo:
Thank you for your reply. That is exactly what I was looking for.

On my Dasaita Max6 (px6) I have measured a consumption between 10-20mA when off and 20-30mA when on sleep. That is after 90s power latch. So that is around 10mA difference. To put things in perspective, my OBD adapter consumes 5mA when the car is off. Definitely worth keeping it always sleep in my opinion.

Not sure if after ~40min it will drop when off. Did not test that yet. Planing to test that on weekend.
[MTCD Software Development] dafunky:
Hybrid assistant is dedicated to some Japanese hybrid cars based on the toyota HSD engine. You can search more information about ”hybrid assistant" on YouTube or try it using google play store (free app).

You found the right genuine "obdlink sx" on your Amazon link. As said before is it usb, just plug it on one of the three usb ports available, and on the obd2 plug of your car on the other side. If you want to get real time data from your car use Torque, if you want to permanently change some car behaviour you can try with Torque but the better app is carista which is dedicated for that (11$ for applying the changes, but free if you just want to check the available features on your car). If you have a hsd engine you can monitor it with hybrid assistant. You'll find useful videos on YouTube.

[MTCD Software Development] [GER]Roxxor:
Already started reading a lot from your signature. A lot of information to take in. Is there a possibility to backup the stock firmware of my device before flashing this ROM?
[MTCD Software Development] Hal9k_:
What is it ?

What app are you talking about ? Why is there no link ?

About connecting BT devices:

In general, the connection of Bluetooth devices to the HU is implemented as follows:

Each device has such a feature as Class of Device/Service, which consists of Major Device Class and Minor Device Class.

If the Major Device Class of the device that we want to connect to the HU is 0x1F (Uncategorized: device code not specified), then the HU will consider this device an OBD adapter. And the OBD icon will appear next to this device.

Otherwise, the HU will consider that it is a phone.

And it is precisely the 0x1F class that is installed in ordinary cheap OBD adapters and Bluetooth modules like this

For phones, pairing is done with the pin code specified in the settings of the Bluetooth application. It can be changed.

And for OBD adapters, hard-coded pin codes 1234 and 0000 are used (first the first, and if it did not work out, then the second).

Moreover, for the long-suffering MD-725 module, only one pin code is specified at all - 1234. :)

Therefore, “cool” OBD adapters that have a different Major Device Class, sometimes completely absent from the Bluetooth specification, often cannot connect to the HU.

So, the Bluetooth module in my Vgate OBD adapter had Major Device Class 0x0B. I changed it to a module taken from a BT module, the link to which is upper, and it began to connect without problems.

About the GPS accuracy.

The number that the GPS Test shows is largely invented from whole cloth.

Since the GPS library calculates it in Chinese. :D

Here is a screen from Ublox native software:

View attachment 4970837

The antenna lies at home on the windowsill.

We look at the value of HDOP

To convert to meters, in different sources, they suggest multiplying it by 2.5-5

This accuracy is obtained in reality.

This happens on some older boards where Android 6 was originally installed.

The solution is to repeat the wipe data until it is completed without errors.

This is a limitation of the MCU.

The authors didn't expect you to connect the piano keyboard to the HU. :D

Hi, I own PX5 device and recently upgraded to 4.01 version of this great ROM.

hi thank you for the great rom!

since using the alternative equalizer i realise that the main volume is lower than before.

after some testing, i discover it is linked to the gain page, by touch the sync checkbox or readjusting the gain slider for the front speakers.

the volume returns to normal, will you be able to troubleshoot that?

And update is without data loss?
[MTCD Software Development] dafunky:
1 - get your serial number in the android settings and pay 10€ here :

http://hal9k.ru/

2 - receive the code by email

3 - go to settings -> auto -> first submenu -> enter serial code.

4 - reboot as requested after entering the code. The HU automatically shows a popup saying there's an update ( 87mb).

5 - proceed to the update, it's fast and painless. No manual action needed, just say ok / ok then it reboots and voilà.

French

Il faut noter le numéro de série du poste dans les infos de build android puis aller ici et payer 10€ via PayPal :

Ensuite une fois reçu le code par mail (aller directement voir dans les spams) il faut aller dans le menu voiture -> premier menu -> enter Access code -> rentrer le code et le poste va demander de redémarrer, puis demander à télécharger la maj de 87mo, enSuite ça roule.
