The only proven way to switch from one android version to another is the bootable sd card method that does not include just the recovery.img, but also kernel.img and misc.img. Another thing is the parameters which includes information about partitions.

So replacing the recovery might not be enough and it will be better to wait for a sdupdate.img for px6 android 9.

How can I install this Android 9 on my Android 8.1 system with PX6? Only found upgrade tutorials for PX5, not PX6...

Would be happy to find some help... Thanks, guys!
[MTCD Android Head Units General] scorillo_ro:
There is no modified PX6 update.img to use for creating a bootable sdcard to upgrade from 8.1 to 9 yet.

Maybe [MENTION=5092263]Hal9k_[/MENTION] will release one soon...

Dasaita px6

Hi my headunit is dasaita px6 rk3399 and have android 8.1 now. How can i upgrade to 9.0?
[MTCD Android Head Units General] Coldswellhh:
HI - Happy to hear that there is an update for Android 9 to bring back the splitscreen...

I bought my first headunit so it would be great if you could tell me how to correct update.

My Build is rk3399 hct.20190409 - can i use the hct4_rk3399_9.0(20190505)?

Do I need to update the MCU too? I have already the MTCE_GS_V3.07_3

Only think is to save the zip to an an SD card and start the update...?
[MTCD Android Head Units General] scorillo_ro:
No need to update your MCU. Just put the update.zip on a sdcard or usb stick and go for it. You can do it from recovery or directly from settings.
[MTCD Android Head Units General] vortxnat:
Anyway to get back the white UI after update?? Was nice and neat
[MTCD Android Head Units General] scorillo_ro:
What update? The hct4_rk3399_9.0(20190505) one contains the so called “white ui”. If you have the “brightness mode” set to auto, then the UI is white when you have the headlights off and is dark when the headlights are on. You can force the mode to be always “white” or always “dark”.

Not sure about the updates from HA.
[MTCD Android Head Units General] vortxnat:
Hmm i used the HA2 update instead of this HCT one. What is the difference though? Is HA for dasaita only?
[MTCD Android Head Units General] scorillo_ro:
No, you can use it. Afaik the main difference is the design of the UI.
[MTCD Android Head Units General] itsretro:
Maybe i am dumb, but where do i find the latest firmware versions apart from this thread?

Also where can I see if the UI has changed with a new version?

Thanks!

Same issue with Dasaita Max6 Rk3399 4/64 Android 9 for VW Passat B7

Dasaita says I should attach a GND cable to the case. This is not a solution for me and I will return the device.

Btw, I do not like the user interface at all.
[MTCD Android Head Units General] typos1:
You can change the user interface by installing a different launcher.

It may be your car thats causing the interference.
[MTCD Android Head Units General] mahtew:
static noise starts when android is up. [with first boot] there is no noise until first sound is played, so >in my opinion< it must be connected with initialisation of sound path. also static noise happens when engine is off.

with previous mcu board i had no static noise (i replaced it with newer one for DSP) so it is not a bad grounding. maybe something is poorly grounded on mcu board?
[MTCD Android Head Units General] Ati_gangster:
I know that I can change the user interface, I did that too.

In all my other Android radios (4xGS, 1xHA, 1xTONE, 1xLM) I have no problem with interference.
[MTCD Android Head Units General] danieleds:
Do you know a consistent, reliable way to access the recovery on this particular unit?

I can't boot the system anymore after trying to update to the latest android version (a minor revision of android 9).
[MTCD Android Head Units General] diablosblade:
I have just got the dasaita max6 rk3399 px6 and the black ground wire solves the noise issue. I have it in a qashqai and I attached it to one of the mounting screws when fixing the unit back in.

My issues are with how bright the screen is at night and finding a better bluetooth audio ad2p app
[MTCD Android Head Units General] typos1:
You could try another A2DP app from the Playstore if there are any (never looked) and if theyll work with the BT module (not sure).

If the brightness is too low on its lowest setting you could try an app which overlays the screen (theres one called "colour calibrator" or similar which might work) or wait for a custom ROM.
[MTCD Android Head Units General] diablosblade:
It was more that the brightness is too high.

So many settings to get used to though.

As for a2dp... it's a strange one as getting apps specifically for android head units or at least ones that work with them is a bit tricky anyway.

I tried flashing to the 5/20/2019 HA2 but having trouble getting developer mode enabled both before and now.

Nothing at all happens tapping build number as many times, nothing at all.
[MTCD Android Head Units General] scorillo_ro:
What do you need developer mode for?

You can access it when in ADB mode. For this you should use "adbon" password for Factory Settings. To exit ADB mode you must use "adboff" password for Factory Settings.
[MTCD Android Head Units General] taxableabe:
I would like split screen as it's not working on my model. I've input the "adbon" and it showed a small notification box on the bottom that ADB mode is on. What do I do now to turn on the Split Screen?
[MTCD Android Head Units General] scorillo_ro:
Split screen is working out of the box in newer versions of Android 9 (May 2019), no need to access Developer Mode.

Anyway, in ADB mode the Developer Options menu should be found in Settings menu, but will be hidden when you exit ADB mode.

Can we have a megathread where recommended brands and if they are indeed MTCD/E or not?

The reason is that there are some brands did mention that it comes with PX6 but whether or not the mainboard is MTCD/E is not mentioned.

So far, I only know Dasaita, and Joying only sells Intel model.

[MTCD Android Head Units General] typos1:
In the entire 6 years history of MTC units no manufacturer or seller has ever stated if their unit is MTC or not, post here and ask if youre not sure if its MTCE.

Joying also use Rockchip processors, bit not using MTC platform.

PX6 bluetooth

Hi all,

I have a PX6 for a BMW and i've been trying to figure out how to enable and use the bluetooth for more than phone calls and media streaming. I want to connect it to a bluetooth ODB2 device.

The PX6 seems to use some of the original headunit's functions and along with some of it's own Android features and functions. For example, i can use the original HU for FM radio, CD, Bluetooth for phone calls, etc. while using the Android for other functions like navigation (and any other android app i can think of).

So i ignored the Android bluetooth for the phone and continued using the original HU bluetooth. However, i've been trying to use the Android Bluetooth for ODB2. I've bought a bluetooth dongle (CSR 4.0 usb dongle) hoping that the PX6 will detect it. However, i can't seem to switch on the Bluetooth on the settings. depending on the Bluetooth App i use, it immediately switches off (1ms on, next millisecond off), or it gives an error saying "permission denied"

I tried telling the PX6 to use the Android Bluetooth instead of the HU bluetooth, just to see if the "Factory settings app" prevents control of the Bluetooth, but i can't find the Android bluetooth on my phone (i'm contacting the seller regarding this).

So now that you have the background, basically, i want to continue using my original HU bluetooth for the phone, and i want to have a full featured Bluetooth on the Android device (like a tablet would have). Any ideas on how this is possible? I'm hoping there's no need to strip the screen and remove electronic components from the PC boards?
[MTCD Android Head Units General] typos1:
Wrong forum - yours is not an MTCD/E unit (the MCU dosent start with "MTCD" or "MTCE"), try the Android Headunits general forum.

I m guessing you saw "PX6" and thought its the same as yours - the PX6 is a processor and many devices use it, so you cant identify your device by that alone, just as an HP laptop and a Dell laptop both with Intel core i5s do not use the same firmware and are not the same.

Help upgrading unit ...

Hi guys,

I have the 4x4Shop BMW F25 PX6 unit running Android 8.1 . It has the RockChip RK3399.

Attached is a screen shot of the versions I am running (6 months old). Is it possible to use one of the latest Android 8.1 or Android 9 MCU and Firmwares posted here (a few posts back) to update my unit?

And if yes, can you share any directions on howto upgrade it? Or point me to somewhere I can find some instructions?

4x4Shop won't help me update it and I would like to get a newer version (to hopefully fix some of the problem I have with the old one).

I am very good with computers, but have never updated anything on my unit... Any help would be greatly appreciated ...

Thanks in advance

Hello,

I have a Honda Jazz II (also named Honda Fit) and I would like to add an Android head unit. I saw on Aliexpress several models. In your opinion, is it better to take a Dasaita with PX5, 4G RAM, 32g ROM, Android 8.0 or another model with PX6, 4G RAM, 32g ROM, Android 9.0 from an unknown brand (YMODVHT) ? Prices of both are similar.

Thanks
[MTCD Android Head Units General] Manuele83:
Px6 will always be better than Px5. The heating problems are common on all the headunits, and the problem is the heatsink that is too small. You can easily improve that. There are videos on youtube. When its overheating the unit slows down, it is not easy to have real problems.
[MTCD Android Head Units General] Flemischguy:
Go always for a 'brand' like Dasaita, Xtrons, HuiFei(KGL) Klyde, Joying or even Ownice... Those brands are the most supported. Stay away from unknows brands
[MTCD Android Head Units General] typos1:
Xtrons is not a manufacturer, they are just a seller and they sell both MTC (mainly GS) and non MTC Android headunits. Ownice do not make MTC headunits.
[MTCD Android Head Units General] Flemischguy:
He didn't ask that, his question was if it's better to buy a well known brand with 'support' instead of an unknown brand that no one knows. I just named a few well known names.
[MTCD Android Head Units General] typos1:
I realise he didnt ask that question, a few things in your response were incorrect, so I just corrected them. :)

The best "Support" for these units = XDA.
[MTCD Android Head Units General] yurtesen:

[MTCD Android Head Units General] ChessSpider:

[MTCD Android Head Units General] typos1:
If you have the DSP version theres no mods for it and you cant use the Wadzio or cs-x(RU) mods, theyre both for non DSP versions.

It also sounds like your screen is broken.

[MENTION=1902805]ChessSpider[/MENTION], do you happen to have the dmcu update file for your PX6 CZ unit? I have a PX6 CZ with 3.06_2, your pictures show 3.10_2.

There is a new dmcu.img file on the site also you mentioned, it's from July 17, for CZ, but it's in the PX5 folder there, no version. I'm a bit afraid to flash it, especially since I have no known good backup dmcu.img.

Second, why do you need an app to sync the contacts from the phone? Mine sync just fine, I think. No voice command for calling, that's true.

Third, I read earlier, in some PX5 post, that the guy managed to calibrate his touchscreen by entering some settings menu. I don't have the link, though.
[MTCD Android Head Units General] typos1:
MCUs are not processor specific - a CZ MCU is the same for all CZ units, Sofia, RK3188/PX3, RK3368/PX5, RK3399/PX6 etc.

In factory settings just export your MCU settings, no MCU back up is necessary.

Calibrate your touchscreen in factory settings, password (normally) 126.
[MTCD Android Head Units General] esziszi:
MCU MISMATCH!

Do not download this dmcu.img, it is *not* for CZ, it is for XRC, mistakenly in the CZ folder.

Still works, but has problems.

Now I really need a dmcu.img for CZ.
[MTCD Android Head Units General] typos1:
Did you export your config before flashing ?

There are CZ MCUs in the cs-x(RU) sound mod thread.
[MTCD Android Head Units General] ChessSpider:
I didnt update dmcu.img; i only updated the ROM.. I dont know what to do to help, but if you do, send me a PM and ill try
[MTCD Android Head Units General] typos1:
You wont get an MCU mismatch if you flash a ROM, only of you flash the wrong MCU.
[MTCD Android Head Units General] latino-7:
Are you found any solution i have same problem
[MTCD Android Head Units General] esziszi:
I have a CZ unit and flashed an XRC dmcu.img by mistake. Android still starts, but there is an "Unmatch" message on the screen all the time and the unit beeps every few seconds.

Temporary solution:

Download McuUnmatchUnlock.apk from the same server (it is at the end of the folder).

Install it.

Start it.

Tap "UNLOCK".

Reboot.

As I said, this is temporary, until you find and flash a dmcu.img file specifically for CZ.
[MTCD Android Head Units General] typos1:
I ve told you told you the solution, flash a CZ MCU. Did you export your settings ?
[MTCD Android Head Units General] esziszi:
I replied quickly to [MENTION=5653239]latino-7[/MENTION] last night, so that they can use their head unit.

I checked about fifteen pages in the MCU sound mod thread yesterday, but for the life of me, I couldn't find a file for CZ. Will keep reading.

I contacted the seller, he promised he'll ask the factory on Monday for a dmcu.img for CZ.

I did not export the settings before flashing. Which is a bad idea and in hindsight, can give [MENTION=5653239]latino-7[/MENTION] extra work, as it did to me.

On my other (PX5 GS) unit, I never needed to, the MCU updates always kept the settings, but that's no excuse.

On this one, I had to check and enable each factory setting manually after the flash, with the risk of getting into a bootloop or black screen or worse.

I did actually get a black screen for a while...of default power "off" (screen off), because I mistakenly touched that setting and put it so that the unit was off by default. The display was black, the touchscreen was not working, unless the car was in reverse or there was a phone call going on, then it came alive. So I called my phone company's kind robot through Bluetooth and while she was talking, the screen was on and I was trying to figure out the setting that screwed up my PX6. Problem is, you have to apply the changes, but the Apply/Exit buttons are at the bottom, under the ongoing phone call overlay, even if it's minimized, and said buttons cannot be tapped. So no saving the new settings.

I think that only by mistake, I touched the power button (no physical buttons on my unit), and the screen turned on, without reverse or phone call. That's when I vaguely remembered a factory setting about this, went there, set it to on and it works.

So one should definitely export MCU settings. I got lucky...for now.

Still, some settings are missing with this substitute dmcu: cannot set steering wheel controller to CAN (so less freedom in button configuration), can't display battery voltage, and it's probably not as stable as a native CZ dmcu.
[MTCD Android Head Units General] typos1:
The cs-x(RU) thread has links to the MCUs in the first post, there are also link to MCU repositories in my signature.
[MTCD Android Head Units General] esziszi:

[MTCD Android Head Units General] typos1:
You have not checked well enough - look at the last few posts - cs-x(RU)'s MCUs are collated by a member and placed in a mega link, plenty of CZ MCUs there.
