In order to update to 9.0 firmware you must follow the instructions on very first page (page #1), 2nd post. Use MX version (Date: Aug 13th 2019. Source: MX. -->) because in my opinion it has all features fully unlocked, and it is a universal firmware.
[MTCD Android Head Units General] DHAmoKK:
Ok, I got an Android Update from Erisin support for my device (from Sep. 21th 2019) and a MCU update (MTCE_LM_V3.38), but I still can't add any security option like pattern, pin or password, still factory reset after a reboot. Additionally, I can only add an applock app for the time the device is running and not rebooted/shut down. After that, the device adminstrator setting and others (like start with device, show over other apps, etc.) will be reset. It's pathetic, there's no way to make it save from passengers access. I tried different apps, like Norton App Lock, Quick App Lock and LOCKit.

They want to send me a return label for an exchange of the device, but I need to know if this is really a defective device/a bug in their firmware or if Erisin doesn't 'want' you to secure your head unit?

//edit: OK, Norton App Lock still works after a reboot, but it loads way too slow, you can easily open settings and/or Play Store and remove it, rendering the device defenseless again.

Desperate to upgrade PX5 Android 6.0.1

Hello all,

I have no idea if I'm at the right place for my question, but as I'm new to android and have spend several hours trying, I'm getting absolutely frustrated. I have everything Mac, from laptop, desktop to phones, but now my car has an Android device. It's a PX5, Rockchip 8 core coretex A-53 @1,5g, ARMv8-A, arm64-v8a, with MTCE_GS_317bd and android 6.0.1

Now, I would like to update my android to a more recent version. As I came to understand, I can't use Android auto, since my car is a Passat b7 2011 and not supported. So, I think I would like the Android 9 Pie. I've updated the MCU (which came from MTCD_GS_v2.56_3) and so far that seems to work. Now I would love to update Android, but I can't find a simple way to do this. I have tried downloading and installing HCT4_px5_9.0_ota(20190813)升级包 , but when I go to settings, about tablet, system update, it will give me an error like it can't understand the file.

So, what do I need to do, who do I need to worship, who's butthole do I have to tickle, in order to get my Android running PX5 unit upgrade to a more recent version?! Is there a simple download, and installation guide, without having to manufacture my own USB cable, solder the motherboard, unscrew my steering wheel or remove lightbulbs?

Thanks all, for your wisdom and understanding.

Regards,

A mac enthousiast in transition

p.s. the reason I'd like to upgrade is because there are several things not working properly. Wifi connection gets lost very often, connecting is as hard as a rock, the UI is crashing from time to time, etc.
[MTCD Android Head Units General] eNubiX:
The only thing you're going to tickle is your own eyes while you read the OP of this forum you posted in. Everything you requested is on the first page. Mainly in post #2. Using mac must have made you lazy... ???
[MTCD Android Head Units General] primemp:
Hahaha, yeah, it has indeed! That's because Mac works so effortless. Updates are easy and compatibility isn't depended on chipset.

All jokes aside, I really love to find out the way HOW to do this. I have no SDcard slot, I will not (read: can not) build my own USB cable and none of the chipsets mentioned in the Hal9K mod is my chipset. I have an rk30sdk.

So, which way to go, without risking a bricked PX5?

Issues with my headunit

Dear XDA members,

This summer i have bought a Android 9.0 multimedia system with a PX5 A53 chip for my Citroën C4 from 2007.

The shop owner said it was compatible through Canbus with all my systems including my parking sensors. Although they arent working, as is my open/closed door indication and the diagnostic information also isnt showing.

The shop owner says he cant help me anymore (after a few months of troubleshooting) I have recieved a new canbus(which was programmed exactly the same way) and a power cable but that didnt help me in any way.

I am wondering if there is a way to get my factory built parking sensors to work because im 99% convinced it has to do with programming since the android system is infact responding to On/Off button of my sensor system (sensors fully function with my factory radio btw).

I hope and pray someone has the answer i am looking for.

Thanks in advance!

Where to check for MCU latest updates ?

Hi there. I bought an android head unit for my Hyundai i30 2014. The unit is a PX5, hexacore , 4gb ram, and came with android 9 preinstalled.

I am wondering where can i check for newer updates ? Originally it came with MTCE_MX_V3.32_1 from 28 august 2019. Is there any newer updates of mcu? Where does everyone checks for updates ? Many thanks

A couple of things to check, did the new screen come with a cable for the buttons, did you plug it in the right connector with the correct orientation, lined up correctly and is it in all the way.

Can't update recovery

I was able to upgrade my MTCE MCU on my LM PX5 running Android 8.0.0 to 3.77_1 but when I try the above instructions I get hung up. Everything goes as planned through step 10 above, but I don't have an SD Card slot. Instead I have an external USB dongle, which I don't see why it wouldn't be the same thing. Step 12 makes no sense to me. I have tried rebooting the unit with my USB thumb drive created with Steps 1-10 and it doesn't boot to that drive and upgrade the recovery to one I can use to install Android 9.0.

I really don't want to pay some guy 10EUR to give me an app that will upgrade my recovery. Is there no other option? I am easily able to install Android 8.0 system updates and MCU updates using the Android Settings route, but when I attempt to install an LM specific 9.0 ROM it aborts the install saying that it "failed to verify package compatibility: Device manifest and framework compatibility matrix are incompatible: HALs incompatible. android.hardware.drm. Installation aborted."

I assume that this is because I am on the 8.0.6 recovery and not 9.x.x

**edit, I tried two different USB thumb drives (1.0GB and 8GB) and both worked for MCU/Android 8.0 updates, but not for the instructions above.

***edit, the ROM I'm trying to install is https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 9/LM since it's LM specific rather than links in the OP.

Ideas?

Vote best reply to posters sense of entitlement.

Doesn't have the skills to avoid paying for a service, but doesn't want to remunerate for the work....
[MTCD Android Head Units General] nic2k:
He's given you the most accessible options, you choose the one that suits you.

I get your HU doesn't have the SD slot neither does mine but the connector is on the MCU and since they use the same MCU for all the different cars find one of the same model hat has the slot and ask the seller to send you a replacement slot and cable for that unit. There's no de-soldering involved with the OTG method everything is pinned. You will have to solder the USB cable to pins though and to be really safe you should buy a strip of pins from Mouser to match the connector. OTH if you're going to play around with custom ROMs having HAL9k's recovery tool will save you a lot of trouble and is worth the money and I'm not even considering that the guy deserves some compensation for his work or you wouldn't be asking for help since you'd have written a tool to fix it yourself.
[MTCD Android Head Units General] objecttothis:
Not wanting to pay for something that I can do for free is perfectly within my right. What makes that entitlement? If you think I'm entitled because of my response to [MENTION=744370]ikerg[/MENTION]'s pi**y response to something I wrote in my post but he missed then I can't help you. Most people respond with a little snark at the impatience of others that don't read their posts entirely.

Don't make assumptions. They are usually wrong. I have Bootloader unlocked and flashed dozens of devices without needing to pay for it. If [MENTION=472138]hal9k[/MENTION] wants to monetize his work, that's his prerogative, just like it's mine to try to do the task without paying for [MENTION=472138]hal9k[/MENTION]'s work. Hal9k is probably doing it by rooting the device and flashing the bootloader android on a rooted device, so for people to not offer help, but instead start calling people entitled when they want to try to figure out another means than the three options given in the OP, is counter-productive. XDA is a forum for helping people and the OP provides three helpful options, but they are not likely the only options and since the thread is titled "Head Unit Discussion Thread" I don't think shutting down discussion of other options by calling posters entitled is appropriate.</end rant>

---------- Post added at 01:03 PM ---------- Previous post was at 12:52 PM ----------

I'm going to try rooting the device and flashing a new recovery via ADB first. If that doesn't work then I'll buy [MENTION=472138]hal9k[/MENTION]'s tool since I would spend more than that in time and parts to solder an OTG cable. I agree that the guy deserves compensation for his work. If I end up needing it, I'll give it happily.

Hi guys,

This is my first post in this forum :) I recently bought an Android Head Unit (MTCE,PX5,Android 9,4Gb) and I have some questions that maybe you can answer. The MCU information of my device is:

MTCE_LY_3.10_1

Do you have any idea of what manufacturer is LY? it is not listed in the first post and I've not been able to find it. This current firmware does not have the "Split screen" option available so I was thinking of updating it with one of the mentioned in the previous posts.

On the other hand, I just installed my unit and I hear a white noise when the unit is on. If I mute it the noise disappears. I've tried to unplug the FM antenna cable but it does not change anything. Do you have any clue on how to remove that noise? Could it be because a faulty installation? I installed it in a volkswagen polo replacing the original RCD510. The only extra thing I included was the GPS antenna that came with the unit and the FM amplifier.

Thanks in advance!
[MTCD Android Head Units General] ikerg:

First of all, thank you very much for you help!!

Gracias de nuevo :)
[MTCD Android Head Units General] zimass:
A big thank you for this information.

I too have a problem with static noise. I will try with this technique.
[MTCD Android Head Units General] Dr. Monkey:
Hi again! I've tried the solution proposed by [MENTION=744370]ikerg[/MENTION] (connect GND to headunit chassis) but the static noise remains the same. Since I don't notice it while driving but only when the car is off, I think I will give up on this and assume that it is something I have to live with. Be as it may, thanks for the advice.

I have some more questions regarding my unit that maybe some can answer:

1. Regarding the firmware update, if I replace my firmware by one of the ones in the first post, will I still keep the apps that came in my original one? For instance, I have one app that came by default called vehicle, where I can see some canbus info (doors open, remaining fuel, etc.), another app to equalize the audio (DSP), another one to set the color of the RGB led buttons, etc. Will I lose those ones?

2. Is it possible to do a backup of the current firmware? I asked the seller to provide the original firmware but got no answer, so I'm afraid I can break something with the update, not being able to restore the unit to its original status.

3. I have an annoying behavior related to the Wi-Fi. I have my mobile set to enable the Wi-Fi hotspot automatically when it connects to the Head Unit bluetooth (so far so good). The problem is that, every time I turn on the Head Unit, the Wi-Fi does not automatically connect to the hotspot. I have to go to the settings an it appears as disabled. I have to turn it on manually every time I turn on the unit. It is worth mentioning that I have enabled the setting that enables the Wi-Fi re-connection to known networks. Is there any workaround for this? Would it be solved by changing the firmware?

Thanks in advance again!

Warning for owners of Android 9 PX5 head units.

If you have a firmware version that is newer than end of May or beginning of June, then you cannot install an older version.

This is a new limitation.

If you still try to install an older version, you will get a bootloop.

The following possibilities are available:

When you get a bootloop, you can enter the recovery and install the

latest version. Then the system will work again.

Another possibility would be to install the Android 9 Recovery via the GPS MicroSD slot. From here you can go back to any Android 9 version.

For users without MicroSD slots it is particularly annoying.

With the ModInstaller Pro you can first install the Android 8 Recovery again and then an Android 8 Rom. Then you can update to any Android 9 version.

Hello,

I have installed the 20190528 version on my Hizpo PX5 4GB and I have an issue with carplay. I am using a white dongle with AutoKit.apk and when I connect the phone to the head unit all I get is a grey screen. Audio comes, video does not.

Has anyone experienced this so far? I am posting here and not in the carplay dongles thread because I assume it is an issue with the firmware and not with the dongle or app as this has not happened on previous versions of android8 or 9 firmware.

Thank you

It's a factory replacement so the connector is the same. Orientation is also correct and I am quite sure that the (single) connector is correctly in place (the touch function itself works perfectly it's just the touch buttons not being recognized).

I am thinking of either a calibration issue (does it even know I touch the buttons?) or a software thing (like missing drivers or something like that?). I already tried different calibrations (via factory settings) and functions (like showing key presses, learning buttons etc. pp.)

Is there any other way to try? I will contact the seller in parallel but I am not quite sure if this is related to the rom or not (I don't want to bother him if I am responsible for this because it may be a rom issue)
