[Android Head-Units] OperatorB:
After a restart no such thing should happen. I suggest try combat the issue from inside the current OS/recovery and/or do a power cycle to the HU.

According to my experience there are as many OSes as many manufacturer so flashing one of the mentioned OS should be the very last desperate try.

Is there any kind of sound what your HU can make currently? Is it completely mute?
[Android Head-Units] JEAS9:
Thanks for answering. The only sound it makes is that of the keys and touchpad
[Android Head-Units] simbac:
mine never recovered from this problem. Tried ereything including OperatorB's instructions but to no avail.
[Android Head-Units] JEAS9:
Can it be something of the equalizer? Everything related to sound is not heard. Anyone know how to reinstall that app?
[Android Head-Units] OperatorB:
Yes it could be the equalizer. Try to reinstall that. If no result then try to reinstall Music app also. You may also do a factory reset(on your own responsibility).
[Android Head-Units] JEAS9:
Install version STM32-20190929 and the problem was solved. :) But ... now the screen is in 800x400 instead of 1024x600.

In hardware information it says:

RK3399 - ROM 64gb - LPDDR4 - 800X400.
[Android Head-Units] JEAS9:
After several attempts. In the end I got it. Thank you very much for the help. Now I just need a good music player ?
[Android Head-Units] aphilgr1:
I have exactly the same symptom. My unit is 1024X600 but the firmware I installed is 800X480. Already rooted

How did you manage to solve it?
[Android Head-Units] JEAS9:
Could you give me more details about your radio? Version, STM..... You updated the version with an .IMG image and it stayed like this? or was it with a .zip?
[Android Head-Units] aphilgr1:
My unit is Erisin ES6292B PX6 STM32 MCU. The link to firmware Erisin gave me was for os_update_HC1E0201-P0N-1.1.4.3.1_20190904_112936.zip. As I had a totally bricked unit that could not enter recovery, I had to go in maskrom mode to flash a firmware only it had to be in *.img format. The only STM32 firmware in *.img I could find was from a Russian forum.

After the first firmware update, the unit works fine but with a desktop of 800X480 in a 1024X600 screen and touch control reversed. The guy in the forum says you need to update OS with en extra update in *.zip format this time. He also says that the MCU is updated as well. When I apply the second firmware, the unit goes back to BRICK mode although I can still see the boot logo!!! Exactly the same happened when I tried to apply Erisin stock ROM. So I am back to the first firmware waiting for instructions to fix the screen.
[Android Head-Units] aphilgr1:
apply export config data

EDIT I gave the answer myself. Copy it on an SD card, insert it on the unit and select the appropriate update (config) from the menu and execute

Does anyone knows how to apply an exported config data file to an Android 9 PX6 STM32 unit?

It comes with a name android_config1582534380185..1 that when extracted includes android_config.xml

A sample of the content of the xml file in the attached picture

[Android Head-Units] JEAS9:
My solution on different radios was this: - (SD) First update the radio with the .img file - (USB) I copied the firmware and the MCU to the USB. Then update the radio MCU file and finally update the radio with the .zip file If your unit does not have USB, you can do it perfectly on the SD card. You format the card and copies the MCU file and the .zip file. Check if it works like this. ?
[Android Head-Units] aphilgr1:
Which MCU file did you use to update the unit before update? Is it this one

mcu-201909181001KC6-1809.upd

or different? Is there a link?
[Android Head-Units] JEAS9:
Yes, I use that file
[Android Head-Units] aphilgr1:
Unfortunately I have hit a wall!

Whatever update I put on the SD card, although works ok from within Android, it doesn't work on boot or from the recovery menu. I tried with two SD card. Card 1 a very old 1 Gig and Card 2 a new 8 Gig. This is what is happening when I try from recovery. folders on SD cards are shown, files not!

When I boot normally, card 1 gives a black screen and card 2 boots normally on Android. Could it be something wrong with some part of the memory? The MCU firmware? Recovery? Actually the recovery of this firmware version 20190929 - 701F is different from my Erisin stock recovery. On Erisin I had the option to update from USB, perform a MCU update and I was also able to enter recovery mode simply by powering up with reset button kept pressed for 5 seconds.

I don't even know the architecture of the system but I guess I am stuck with only one option: Since I can still go Maskrom mode and load firmware from there as long as it is in .img format, I need to find an .img version for 1024X600 displays. So far, he 800X480 from the Russian forum is the only one I have found.

Desperately looking for a link to 1024X800_Firmware.img to get rid of this headache!!! :eek:
[Android Head-Units] Malaysk:
I ordered this device from China too)
[Android Head-Units] aphilgr1:
Success!!!

I managed to flash the latest update from recovery => Apply update from ADB!!!
[Android Head-Units] aphilgr1:
That's big news! Are you planning to create a custom firmware for STM32 version MCU?
[Android Head-Units] marchnz:
That's great news, well done. For the benefit of the community, would you mind posting what steps you took to recover your device, along with any detailed information.

Also, from what I understand, OTG is readily available on these units, directly via the USB port, with no mods or removing the SOM.
[Android Head-Units] aphilgr1:
Correct me if I am wrong, but from what I understand, any Rockchip unit can be flashed in Maskrom mode with standard male to male USB cable. A simple search with plenty links here

I will post my experience on un-bricking my totally bricked unit at first chance
[Android Head-Units] marchnz:
No, your assumption is incorrect; not all RockChip processor based Android Head units can be flashed via OTG with a simple Male to male cable - that's why I reverse engineered the MTCx units to create a solution. You didnt even need to remove the SOM, whereas for MTCx units, in most cases, the SOM must be removed and a "JIG" made to get OTG.

Again, you seem to still be confused about the different types of manufacturers, you dont have an MTCx device. You also seem to be confused by the terminology.

OTG = USB 'on the go' flashing via USB male to Male

MaskROM = Forcing the RockChip System On Module to enter a factory mode to force writing of the nand/emmc storage, by shorting pins on the SOM [ this is often required when storage is corrupt/bootloader corrupt]

MASKROM, is not necessary, usually LOADER MODE works OK

Loader Mode = The standard mode of flashing via OTG, where the storage bootloader/recovery is intact.

If you list the steps you took, you can then help others on the XDA community

Anybody of you got the Netflix App running? I tried some versions but no one worked.
[Android Head-Units] nobodyknows1:
I received my PX6 unit with STM32 and obviousoly a new MCU Version STM32-20200103-11-KC6-33. When I go into reverse it shows me the cam picture and in a small window the car pdc. Is it possible in this units to deactivate the cam picture so that you can only see the pdc radar? I saw some videos how to do it in xtrons and so on but I can´t find it in my unit. It´s an Eunavi unit. And I also found a bug, when I go into settings - display and want to change the font size, it changes it but right afterwards it switches to the rearview cam picture and stays there until I restart the unit. Any solutions for this?
[Android Head-Units] nobodyknows1:
and is it possible to change the fm radio app? Mine is showing only the frequencies and not the channels name. Also a very annoying thing is that it always makes a sound when touching the screen but I can´t find anything in the sound options to disable it. Do you guys maybe have some solutions?
[Android Head-Units] DreadfulDrummer:
On my unit, that horrid sound can be deactivated by going to Settings - General - Buzzer, toggle it off.
[Android Head-Units] mandarino22121958:
hi can you tell me please what kind of cable do you use to connect it to the two holes?

Is it possible to use internet vi bluetooth tethering instead of WIFI hotspot. On the page of the dealer it says that it would be possible with BT 5.0. I know that there is a lot of stuff on the pages which just isn´t true but still hoping :) When I connect it via BT and allow tethering on the phone, the unit switches off WIFI and next to the WIFI and BT sign an arrow appears pointing in two directions but the unit stays offline.
[Android Head-Units] aphilgr1:
You only need to bridge the two holes whichever way like with a loop cable and use a male to male usb from the unit to your PC
[Android Head-Units] mandarino22121958:

[Android Head-Units] DreadfulDrummer:
I haven't tried bluetooth tethering but, as far I can tell and have gleaned from forums, the Bluetooth module in this thing is more like that of a Bluetooth speaker or headphones and can't be used for anything other than audio.

Don't ask me how because it didn't seem to work when I tried but, when I opened the BT Music app a while after trying, I found that I'd managed to pair my OBDII adapter. A few apps recognised the adapter and apparently connected but then wouldn't communicate with it or recognise the ECU at all.

I read somewhere on here that someone had some luck using a USB Bluetooth adapter; supposedly plugged it in and everything worked as it should.

I'm considering getting a Bluetooth 5.0/5 GHz WiFi adapter whenever I'm allowed to leave my house. :good::laugh:
[Android Head-Units] nobodyknows1:
That´s a pretty good idea with usb bluetooth adapter :) but most of them are compatible with Windows. Do I need one which is compatible with Linux or are there any for Android? And the other question is, when I connect the phone to the usb adapter will the phone app work on the unit so that I can answer calls?
[Android Head-Units] DreadfulDrummer:
All great questions, for which I have no answer :D

I'll look into it eventually and probably ask that person who got one working if there was anything special about it.

Hopefully Android plays nice with WiFi dongles/Bluetooth tethering to a dongle
[Android Head-Units] V3nn3tj3:
Mine didn't do it at first, but it works perfectly tho. Takes a while before it becomes active and as long as wifi is connected it doesn't really work correctly. Try turning your wifi off.
[Android Head-Units] nobodyknows1:
I tried different phones (IOS and Android) with and without tethering wifi on and off on the unit but nothing worked. Only thing is when I allow tethering on the phone, the unit disables wifi and the two sided arrow appears next to the bluetooth sign. When I turn off tethering on the phone while it was trying to connect to a page it says connection closed. So it is trying to use the phones connection but it can´t :D
[Android Head-Units] nobodyknows1:
I found out that when I turn off wifi and in the settings I turn off the automatic start of wifi I starts nevertheless after reboot. How is it with your unit?
[Android Head-Units] Skuroskok:
Hey

I speak English poorly but I will try to present my problem. Thank you in advance for your understanding and response.

I bought the EUNAVI 2din radio. Android 9 RK3399 ROM 64GB DDR4 4GB ( STM32-20200103-11-KC6-33 )

Dual- core Cortex-A72 1.8G

Quad-core Cortex-A53 1.5G

Linux 4.4.167+

I have a problem with the EQ application: -

The application is strange because it looks like a combination of two applications into one.

I can't control the subwoofer volume

- I cannot change the volume of the front / rear and right / left speakers

(when I start the application, the speakers do not change anything)

It's the same with delay. Zero reaction.

The speakers are connected to RCA

He writes with Chinese from EUNAVI. For a month they have been pretending that everything is ok.

Anyone have an idea how to fix it?

Has anyone got a better version of the software?

How to add screenshots here in the forum??
[Android Head-Units] AKInSIDE:
Hi, i have same PX6 Radio with STM32 MCU and DSP but different Front Panel, also from EUNAVI. Same Problem on my Radio. Connected with RCA. I think the Software is so bad or the Hardware is in the complete Production a faulty Design. Also what is really anoying is the short ACC Delay (Standby of the Device, only 2 hours), and the stupid Autorun of the factory Musik or Radio App.

Eunavi also tells me that anything is perfect working. My AMP is faulty that the DSP Delay setting is not working. Next e-Mail they say the Radio Design is to use the Original Speakers directly to the Radio. Then i ask myself why are RCA outputs there? Today they would send me new Firmware and new MCU, but the Links dont work. I share this Links when i get working one.
[Android Head-Units] Skuroskok:
Hi.

Thanks for the answer.

I wrote with the seller for a month. He first claimed that all functions would work as under-loud speakers under RCA (hi-level)

then stated that they will work only under ISO (lo- level)

Generally the seller is lying.

He also sent me new software but I didn't wait.

He doesn't talk to me now.

The software is bad.

As soon as you get the link to the new MCU, please share. I look forward to it!

Yes I have the same thing only 2 hours on ACC.

I also have the same after turning on. radio or music.

what country are you from? If i may know ?

Rockchip PX5 with MCU STM32 bricked

Hi, I have a PX5 with a MCU STM32 which is bricked. After using the unit for 2 months out of nowhere, the screen is black and doesnt start up anymore. Ive contacted the seller, they send me the original image and an instruction to flash using factory tool 1.65 via the USB on the back side (1 of the 2).

Now when i connect the unit is recognized and already in maskrom mode. When I try to flash I get the following error:

Is this an hardware issue? When i try to unpack the image i also get an error: Unpack union firmware failed. Does this mean the firmware i corrupted?

Is there any other image i can try to rule out that the image is bad?
[Android Head-Units] nobodyknows1:
I have the same unit as you both and also from the same vendor. Long conversations with Eunavi lead to nothing. Which MCU Version do you have? Is the ACC dealy autamtically switched to on or do I have to turn it on manually? I´m working on the unit at my desktop right now, trying to set it up properly for the car using wifi.
[Android Head-Units] AKInSIDE:
I have to set the ACC Delay manuall. First it has instant off.

My version of the MCU is: STM32-20200103-11-KC6-33

I don't know if you ask, but:

For me, after switching off the engine (acc off) the screen goes out after 1s.

Can you send me these EUNAVI links? Will I check if they work?
[Android Head-Units] nobodyknows1:
I have the same MCU. When I was writing with Eunavi, before I gave up; I asked all the time for an update but didn´t get one. Our MCU seems to be from January 2020, I doubt that theres´s already a new update.

[Android Head-Units] nobodyknows1:
Thank you for the links

My MCU is STM32-20200103-11-KC6-33 the one in the link says mcu-202001031001KC6-1027

my OS Version KC1E0110-P01-1.1.4.3.1 - BLINK161 - 20200104 - N3 the one in the link os_update_KC1E0110-P01-1.1.4.3.1_20200323_160300

Blink161 is my bluetooth module. Now my question, do you know if the digit right after the year 2020 seems to be the month so the os version in the link would be newer than mine but can´t find out if the MCU version is newer or not.

Update: I installed both, MCU and OS, MCU version stayed the same as before but the OS seems to be newer.

Update 2: Finally internet via bluetooth is working :) but there´s a downside. Wifi still starts automatically even if the option is turned off. And the internet connection via bluetooth only works when wifi is turned off. So I have to turn it off manually to make the internet work.
[Android Head-Units] Skuroskok:
OOO :) great.

I downloaded the new OS.

The MCU link does not work (asks for the key) :(

Please send the key to the file or post a new link to the MCU.

Explain please

how to make an update?
[Android Head-Units] nobodyknows1:
The link is still working and it didn´t ask me for a code. You have to delete both empty spaces in the link.

To update you need to format a thumb drive in FAT32 and put the mcu file on it, but first you have to rename the mcu update into dmcu.img

after that delete the file from the stick and put the OS file on it as it is. If it doesn´t work with the thumb drive do it with a sd card, that worked for me.

So internet via bluetooth works great now but it´s annoying that you have to turn off wifi everytime even though the automatic start is turned off. I mean why does it have this switch even though it´s useless. Does anybody know how to maybe solve this with tasker?
[Android Head-Units] Skuroskok:
SORRY!!. I restarted the computer and the link works. Strange thing.

I uploaded these two files to a flash drive and Sdcard, I put it on the radio and nothing happens.

I have never done an Android update.

Please help. What exactly should I do
[Android Head-Units] nobodyknows1:
not both, first mcu after update the OS, try to do it as I wrote in my post before
[Android Head-Units] Skuroskok:
ok, THX! I updated the OS

MCU I did not update The version numbers are the same.

Unfortunately, Balance / Panorama and DSP (speakers connected to RCA) still do not work in the EQ Application :(
[Android Head-Units] nobodyknows1:
Have you tried the secret settings? There is an option where you can turn on DSP 5.1 which is off by default
[Android Head-Units] Skuroskok:

[Android Head-Units] braisel:
Hi guys,

I just tried to install the last postet mcu update from this thread, when I put it in my usb slot it will open up music player, even though I named it as dmcu.img. When selecting it in file manager it asks me to override current settings and gives me an error in second step saying something like "wrong backup file".

My current MCU version is STM32-20191028-11-KC6-41 with Android 10.

Those china devices man, always the same struggle:D

Actually everything is running more or less, except my remote steerings keys for forward/backwards are only reacting with system apps, like the standard music player and so on. No third party apps/music players are able to react. Wtf.

Any solution for this?

And a third question regarding root, as I want to install viper and ad blocker. I found two links, are they both working?

Have you tried it with the sd-card? Mine didn´t work with usb either but no problem with the sd-card.

about the keys working in other apps, There was a similar problem with the idrive on a bmw unit and it worked after it was inplemented in a new software update. So I think the keys will work in other apps when someone puts it into a update.

I rooted mine with the method in your second link but I have Android 9. I think it should also work on ten.
[Android Head-Units] DreadfulDrummer:
Not super important but get an app like CPU-Z, for example, and check the API Level. It'll most likely say level 28 which is still Android 9. Like I said, it's not super important but some of these sellers like to lie about trivial things like this. It is good, however, to know these things when making modifications to your device.
