This happend also with my Eunavi unit. After tried to go back to the stock firmware, the whole unit came in a bootloop. I tried everything to enter the recovery, also created a recovery disk. Nothing helped, so I decided to send the unit back to Eunavi and they stated that my motherboard is faulty. So there is a link between the Rom from Malaysk and go back to stock rom. Somehow it's bricking the unit. I waiting over a month to receive the unit back. I expect to have the HU back next week. I keep you updated. See a previous post of my issue I had: https://xdaforums.com/android-auto/android-head-units/eunavi-px6-stm32-android-9-stuck-boot-t4127687

I also agree with your opinion. I also have many years spend on this forum (Especially Android mobile development). Malaysk does a great thing with developing a improved version of the Rom /Firmware, but lacks of quick support on the paid version. A problem I have with this rom is the lack of clearly instructions of downgrading the unit back to stock firmware and supply the correct instructions and (recovery) files for support. A lot of his instructions came directly of another Russian Forum named: 4pda.ru.

Too bad i still can't connect my OBD2 Adapter. I had the issue with a newer stock rom version than yours, so i deviced to try your older FW version and rom, but it still doesn't work. Pairing is not possible ? anyone here uses an OBD2 Adapter?
[Android Head-Units] Michalec:
Yes, I have the same problem. Need to use my phone to connect with OBD2 adapter.

Seller said that this is "normal" with bluetooth 5.0, but I'm pretty sure that this should be working, even with multiple devices connected (because on STM32 you can connect only one device at the same time).

I don't know if it's software problem or hardware (I've read once about low-power bluetooth modules, maybe this module is used in HU?).
[Android Head-Units] tomygunner:
No OBD2 connection works at all. I reset my system to factory settings and tried again. When i click on the device nothing happens. It doesn't react at my click. Tried 2 cheap OBD2 Adapter and an more expensive one the UniCarScan. The cheap doesn't react on clicking and the UniCarScan reacts, but dissappears and still isn't paired.

I was also thinking about it to ask the seller, if a BLE 4.0 would work with this unit. I have the Threecar PX6 for my mazda

[Android Head-Units] V3nn3tj3:
Thinking about getting the full version. But three things i noticed.

I can still not connect OBD scanner. I cannot see the device under bluetooth settings, when going to phone i can see it and select it but it dissappears. So no way to connect it.

For some reason my internet over bluetooth doesn't work, it is always very iffy, might need to try again.

My DAB has horrible reception, might not be the rom but the receiver, altho i had perfect reception with stock rom.

I can live with all of it except for OBD. Anyone any idea?

Now I have the rock chip and Stm32 but am on Android 8. Can anyone help me on how to upgrade to Android 9? If possible at all.

It also looks like the setting item hiding is password coded and the vendor can't remember the password.

Error blackscreen because adjust screen

Hi all,

I have an eunavi with PX6 rk3399 STM32. I installed your rom (malaysk ROM) several months ago (just when you launch it as the first STM32 custom rom). Everything has been well until yesterday, when I tried to adjust the screen values through the native panel where you can adjust the Brightness, Contrast and saturation. I just click a little bit the saturation bar and suddenly the screen becames black. Now when I turn on, the welcome message appears, but then nothing else is displayed. I know that the radio works, because it connects the phones bluetooth, I can listent the radio... etc. Just the screen has been misconfigurated.

So, after that, I tried to reset it pressing through the hole and it restarts but, even after 30' of press, nothings happends, it just restart it and nothing more. How can I reinstall the rom? It has SD slot to make a bootable IMG but I don't know how to do it. Or someone who knows how to entrer to recovery mode? I tried this youtube.com/watch?v=J5RgatweiP8[/url] but doesn't works!

I have a cabrio with a veery good sound system... hahaha it is not very ejoyable without the screen..

Thank you guys hope we can find a solution.

Hi all.

I have a problem with my equipment, it is a PX6 rk3399 STM32. It's been a while since the screen started to malfunction and I can't see much anymore. It begins by superimposing screens of the same rom without sense, the touch functionality is ok, but not the visibility, after a while it becomes dark unless something changes and thus only refreshes what changes, I hope you can understand me and send an opinion to fix it. I send you images so you can see. Thank you very much for what you can do. Regards.

I have also the Threecar PX6 with DSP. There were a fake android 10 installed. I put the Malaysk on it and it works great. DSP is working good with 30 EQ settings.

I have same issue with the OBD2. Sometimes it's connecting Sometimes not. I'm in a discussion with the seller. They promised to release soon a new upgrade for the OBD2 issue.

And i use the Amaga Car Launcher. It is the best Launcher for head units right now.

When car start, do your 30 EQ remain as your custom setting or back normal?

Update

Past week I received my Eunavi PX6 Rk3399 with DSP HU back from the Repair center in Poland. It took almost two months before I received my HU back from repair.

After I installed the HU in my car, I immediately noticed that they replaced the motherboard with a wrong one, version without DSP. They provided me a MCU with soundchip: Realtek 5651 instead of

Also my rear camera and DAB adapter are not working at all. At the moment they are busy with a solution. Keep you guys updated!

In the meantime Eunavi sended me two files to update the OS and MCU for HU. Warning: It's for the NON DSP version with a rk3399 and PX6 processor from the brand Eunavi / Bosion also known as model: BX-AC01 But those updates didn't solved my issues.

I re-uploaded the MCU and OS file to my private cloud as a mirror:

MCU update: Click here

Mirror: MCU update: mcu-202004031001KC6-1616.upd"]Click here

OS Update: Click here

Mirror: OS update: Click here

Instructions how to update: https://www.youtube.com/watch?v=MaSc65PUJjQ&t=44s

Part 2:

After I tried all the above, I installed the Malaysk NON DSP lite ROM, but it didn't solved the issues with the camera and DAB either.

What I did notice in the Malaysk Lite version of the NON DSP ROM:

- Head unit sometimes random reboots, especially when I use Waze navigation in combination with the standard music player. After the reboot, I lost all my sound settings. Some kind of memory overload?

- Embedded music player lacks some basic options. It can be solved, by installing poweramp or other app, but this will lack the integration of the OS.

- I Installed Viper4Android in combination with root acces, but this decreases the volume a lot.

- FM RDS is sometimes not working

- FM Signal quality is poor and very sensitive (I think that this is more a hardware issue)

- Bluetooth ADP music stream, crackles sometimes (yes I put the phone in a distance of approx 10 cm). A restart solves this problem.

It's also a pain in the *** to get in contact with Malaysk, this time I sended him a mail to request the NON DSP full rom instead of the DSP Version. But i got a return to sender, that my mail is marked as spam.

I payed 20 dollar for his ROM, but the lack of support is really a headache. Can't get in touch through mail or through private messages on XDA.

For now on i'm discussion with Eunavi, they don't understand, that they repaired the Headunit with the wrong motherboard swapped...:silly:

Keep you updated.

But after two days I wanted to reload fresh Malays ROM. Rocedure went unsuccessful and now after car logo there is not android bootloop (as in my earlier case) but dark screen that blinks for a fraction of second every half a minute. Now pushing reset button for 30 second or pressing five times in a row doesn't do any good. I'm thinking what to do now.

This happens also with my unit, when I want to revert to the stock image through the normal update procedure. My whole unit came in a bootloop.

Why the launchers from the MTCE devices cannot work with STM32?
[Android Head-Units] airbay:
I think that it have to do with how they designed the architecture (microcontroller) and the way they handle execution code. (compatibility with the launcher). But [MENTION=3590033]Malaysk[/MENTION] can explain this better I think.
[Android Head-Units] _KoSTeK_:
Try to format the USB stick in FAT32, copy OS file on it, plug USB stick in external port and turn radio on. If the screen is still dark try to push RESET button for a while. The system should be upgraded.

I also have Eunavi PX6, 4GB ram, 64GB rom, DSP. On Saturday I tried to upgrade it to Android 10, I plugged USB stick and pushed forward to upgrade. The screen went dark, I've been waiting for about 30min, during this time nothing happened. Only after I pushed Reset button device started to upgrade.

Who else is experiencing problems with rear camera and getting a green screen? I'm curious if this is also a hardware related problem. The ROM from Malaysk with the camera fix didn't fixed the issue.
[Android Head-Units] rudix78:
I decided to go the hard way. I made the OTG cable and connected directly to the motherboard. Then sideloaded img firmware in LOADER mode. Radio is back and alive but I need to test it and install all my aps. I think this was the only way.
[Android Head-Units] airbay:
Hi Rudix,

Can you share your instructions with how to connect the OTG cable directly to the motherboard? and how to sideload the img fiirmaware in loader mode? In this way we can group the recovery instructions for this type of units.

Thanks in advance!

My Findings so far with Malaysk Rom:

- Local Music app after sometime closes randomly

- After starting the HU it's not showing the app icons in the car app directly, after I swipe left & right they appear.

- Rear camera still have some issues (I think a hardware related)

- Randomly system reboots, I don't know if it have to do with multiple apps running at the same time. Memory issue or CPU heat issue?

- The screen saver is by default enabled, and overlaps other applications (can be annoying)

- The Equalizer waveform is by default enabled, also intensive for the HU in CPU

- Wi-Fi is not always connecting automatically to my Hotspot. Sometimes it needs manual trigger by going into the menu.

I try to get a log to find the reason why my headunit is randomly rebooting.

Does anyone know if the PX6 STM32 is better than the MTCD/E one, and whats the main differences?
[Android Head-Units] rudix78:
This one is the worst. I used to have MTCD before and have intel sophia in other vehicle. With this stm32 you never know if it will load system or freeze in the process. At least in my case HU is unreliable (but is also the cheapest).
[Android Head-Units] Michalec:
In my case STM32 unit wasn't a cheap one, but I've received half refund. I also used to have MTCE/D headunit and comparing to STM32 it was a lot better in case of functionality and stability. STM32 based with PX6 are faster, but lacks a lot of must have functions. Maybe after some updates they will fix those annoying problems with STM32 MCU, like Bluetooth that can connect only one device, shutdown delay working as it should, wheel keys working for every music application, not only built in and a lot of other minor stuff...
[Android Head-Units] Moufa:
In my case didn't pick it for the price but because the seller claimed that amplifier chip TDA7803A is better than TDA7851 and the DSP is an AKM7738. I have tried an older unit with TDA7851+DSP MTCD/E but wasn't that pleased with the sound quality. I think that one comes closer to the sony factory radio. An other thing is that supports converse+ fanctionality for Ford mondeo something that was missing in the old unit, and i think that has to do with STM32 MCU. But yes there are many bugs, it does freeze and reboots occasionally, the android fanctionality is very limited, I can't change the annoying ringtone for BT calls, notifications are not visible in the dark theme and launcher is dull.
