Hello Guys,
I really need some insight on this problem:
I have a KLD (http://www.eonon.com/Car-GPS/Specific-Car-GPS/Mazda/GA5151.html) unit for some time now, but since September it wasn't in my car because I was preparing an audio upgrade. As one of the last steps I've checked out the HU and I wanted to upgrade to the latest MCU&FW, but the unit wouldn't turn on. Since it's on my "workbench" I've checked the cables, fuse, the external PSU, everything i could, but it did not help. The unit worked flawlessly in the car and on the workbench 2 months ago. Nothing changed. Now it won't turn on, not even the fan at the back of the unit. The screen and the button backlights are also off.
The one confusing part is, when I push the power button with reset for a few seconds, the unit comes to life, and goes into recovery! I can flash a ROM, clear the cache, etc., but when I reboot the unit from the menu, it turns off, then the button backlights flash once, but nothing else happens. The unit stays turned off.
So far I've checked:
- Fuse
- External PSU
- Power button
- Replaced the SOM (The unit is RK3066 originally, I'm using it with RK3188)
- Tried different ROMs
- Disconnected the DVD drive
Nothing helped. I can get into recovery, but I can't boot the unit, no matter what SOM (or what ROM) I use. I would really appreciate some help, because I ran out of ideas.
Thanks in advence!

Ok, the big conclusion is to use the multimeter first. Magically, ACC was not even close to 12v. Switched to another PSU, everything works.
Hi all!
Recently I had a few problems with my MTCB-MD, but I managed to install new Android OS via PC and RK Batch tool. I still have a problem with a POWER BUTTON (and all buttons on the right side). Definitely the problem is MCU version. Stock was MTCB-MD-1.83V but since I updated it with MD-2.67 there is a problem with buttons, POWER BUTTON acts like HOME button and buttons on the right side (EJECT, MENU and BACK) are not working at all. I have tried to change a keymap in factory settings but buttons are still not working.
Question is: Does anyone know where to find MCU version MD-1.83V (MD-2.08V is oldest I could find) and is there any way to flash it from PC ( since POWER BUTTON is not working therefore I cannot make any selection in Recovery menu)???
THANKS IN ADVANCE!!!
Is it possible to flash MCU MD-2.08v with ADB, or maybe simulate power button key with adb or some other software?

No - the MCU has nothing to do with Android, but you can connect a mouse to your unit and do it that way.
Thanks @typos1! I figured out, but forgot to post
Last year my GF bought me Corto WKB-01 for controling PC when watching movies etc...I tried it on headunit and it works. In recovery i was using arrows to navigate and OK/ENTER key instead of POWER and managed to install MCU version MD-2.08V but POWER button is still not working. Definitely if I don´t find factory MCU 1.83V I am going to install in my car wipp switch on ACC line to keep HU off when I need only engine running or steering wheel unlocked....

It is strange it does not work, have you tried contacting your seller and asking for the MCU ? Have you tried different key maps with v2.08 ?

To be honest I didn´t tried other key maps, I´ll try it today. POWER button now on home screen acts as MENU button, and in the apps as HOME button (Previously it acted as HOME button on short key press, and on long it was opening navi app).
Unit was bought used (I broke my rule about not buying used electronics) for a more than a fair price (about 110-120$, unit was old about a year and dude I bought it from was 10km far from me). I´ve tried on net to find manufacturer but for MD someone say it´s Rhythm Audio (no info about that manufacturer on the internet) and someone say it´s unknown. Only sure thing is that it´s from China and it´s not any of the other well known unit manufacturers (JY, KLD...)... Anyway, my mistake paysback, I didn´t run backup of original Android and MCU before update But definitely if i don´t fix it I will install a separate switch.
I had a problem few months ago while servicing my car suspension, I had to unlock steering wheel and HU was running on all time.
The other reason I need power switch is that HU draws a lot of power from the battery. Since I have TDI it draws aditional power from battery for heater plugs (especially in cold days). In a combination with HU automatic power on via key, I am afraid that I will soon kill the battery.

No, you didnt make any mistake, its a good unit for a good price, I have heard of people with similar a problem who bought their unit new.
The problem is that we do not have many MCUs for this type.
It is impossible to back up the MCU so you made no mistake there either.
And also, most modern electronics are from China, whatever badge they have on the front (the iphone is made in China for instance).
An extra power switch is a good idea anyway, but you could also try remapping the buttons using an Xposed module, you could also try another ROM that may make your buttons come back.
Another thing you could try is upgrading back to v2.83, somehow this make make the buttons work correctly, I have heard this working before. And have you tried the "touchmap" option in factory settings ?

No, I didn´t tried touchmap because, but will. Also, I will update agaon MCU to v2.83 because it makes HU with latest Malaysk ROM work more stable. Swich will be installed soon, along with switches for aftermarket seat heaters, just to find the right place on dash. Thanks man for your time and patience, hope it will be ok.
No, I didn´t tried touchmap because I was not sure that it is related with hard keys , but will do. Also, I will update again MCU to v2.83 because it makes HU with latest Malaysk ROM work more stable. Swich will be installed soon, along with switches for aftermarket seat heaters, just to find the right place on dash. Thanks man for your time and patience, I hope that I would fix it.

Good luck, if going back to v2.83 doesnt restore your buttons, hopefully remapping them will
I just bought a PX5 unit, which seemed to be working perfectly until I finished installing it into my car and now it has become unresponsive with a black screen and a yellow rhombus with an exclamation point in the middle (unable to upload image as new user).
If I turn off the ignition, it will turn the stereo off and the android screen briefly shows before going into sleep. None of the buttons are allowing me to get past the screen and in to android. The reset button seems to do nothing, android is definitely running in the background, just unsure as to why this screen will not close. Any ideas?
Hi, I think I saw a yellow rhombus with an exclamation point when I was installing my radio and rear view camera was not connected to the radio. I think that it is a warning about missing video signal when radio is displaying live feed from a rear view camera.
So, one explanation for your issue could be that the radio thinks you are reversing, and the rear view camera is not connected to the radio. If I understand it right, radio can switch to rear view camera display mode based on two conditions 1) canbus information 2) +12v trigger signal.
For the condition 2), you could check that nothing is unintentional connected to reverse detect wire. If that does not help, then you could perhaps try to disable reverse view feature in the configuration menu before installing the radio to the car and/or find a working canbus configuration settings.
Please notice that I'm a beginner with Android head units and your problem might well be something totally different!!
Thanks for your reply. Some of your post seems to relate to my issue definitely, I think it is linked to the rear view camera which is currently disconnected. However I am unable to get into any configuration options. None of the buttons/resets I try get me past the exclamation screen, I can only see android once I turn off my ignition when it tells me it is closing down. None of the various reset button combinations seem to do anything with my head unit either, can't seem to reset it properly. Its strange, I will reattach the camera tomorrow and see if that brings any joy. I don't know anything about this stuff myself but I am wondering if I did something to the head unit to brick the non-android side somehow.
Edit: Unfortunately reattaching the camera did not change anything.
Update. I have managed to find a way in to the Android side if I connect my phone via bluetooth to the stereo, it then lets me use the split screen function via the top bar menu to put the warning screen other screen to the side, however whenever I touch the screen or attempt to use the android interface, my stereo goes back to the warning screen, none of my inputs via the stereo buttons or the touch screen seem to be registering with the Android side? Very confused. I have also tried as many button combination resets I can find and I have not been able to successfully get into the recovery menu, or any change except rebooting.
Was your unit professionally installed?
Also, what did the re-seller suggest when you contacted them for support?
No the unit was not professionally installed. I am not sure how I've become stuck with the problem. I made some minor changes in factory settings but nothing I thought would of caused this. The seller is yet to respond and its been a couple of days, but I have requested the hardware reset methods for this unit or any other solutions.

Check the reverse wire on the back of the unit...if necessary disconnect it to ensure no reverse signal is received.
If your unit can boot into android normally then you will have to figure out why the reverse wire is receiving signal .
Check your connectors to avoid any of them to be loose.

Everything has been disconnected from the unit except the power cable to car and and canbus, from what I can tell nothing is loose. Unit will not boot without the canbus box whatsoever, not sure if that is meant to happen.

Yes, canbus decoder need to be connected for power up the HU. If you dont need the decoder box you need rewire the harness.
I think I am going to have to request a refund and return it. Still no reply from the reseller and I am not sure what else I can try, everything that is not needed to power it has now been removed. I can't send links or else I would update the thread with a video of the touch/physical buttons being completely unresponsive even when I manage to get to Android. The unit has definitely developed a fault and I am unable to reset it. Admittedly it could be my fault somehow as it was working for the first few boots, but unless they give me something to try I am just going to have to send it back.
Quick bump. Has anyone got any further ideas? I bought off Aliexpress so contact with the seller is slow and painful, they do not seem to understand the issue and just keep telling me to disconnect all wires and reconnect. Which has been done many times. If anyone wants to post a link to the video for me I would be happy to send them it privately.

I would start a dispute with them. I had a device that they sent with similar problems and plenty of issues, which they would not help with or would not understand. Best option is to dispute to get a new device or a full refund. Could you send the video?

Yeh I have a dispute open currently, just was hoping it would inspire the seller to actually offer up a working way of resetting the device. Had to add link below seperately as needed to be ten or most posts.
https://www.youtube.com/watch?v=ujHacKESAT8&feature=youtu.be
The stereo defaults as the warning image black screen and I can only get android up using the multiwindow button with a long press. Then the android side will not register any input and will keep trying to put the black screen to the front.
Update: I have been told by Aliexpress I can have a partial refund and keep the unit, or a full refund if I return to China. Anyone have any ideas how I would go about resetting the unit if I took the partial refund? To be honest I think my only option is to return it and get the full amount back but any ideas would be welcome! Shipping to China and awaiting a refund is going to take weeks, would rather just get it working if possible.
deano35: any progres? I have the same problem as you. This is my post from PX5 MTCD/E Head Unit Discussion Thread
" Hi , I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6 Thanks for any advice. "
Take a look on the video, its similar as yours.
Xtrons PB76M209P, PX5, Octa, 2gb/16gb. Stock Android 6.0 ROM, as supplied by Xtrons.
This unit has always had random disconnects of all the USB ports, but they have always reconnected
after a minute or so. Annoying, but not too serious.
Now it has totally lost all USB's.
Tried recovery menu reboot, clear cache and reboot, reset button.
All failed.
Any Ideas before I dismantle half my dashboard to remove the unit?
I've emailed Xtrons, but no reply yet.
Cheers,
Mike.
Xtrons replied:
" would you like to buy new USB cables from us and try again?"
No.
This unit is less than 5 months old!

hi mike,
this problem is known! you have to open the unit separate the px5 board, clean the connections and replug the core-board. pls. also do the "cooling-mod" AND the "usb-power-mod". explained in the video (only german).

Hi All,
I recently updated MCU and firmware to latest firmware on Dasaita's site:
MCU V3.69c：https://www.sendspace.com/pro/dl/pf1zz4
Android 10 Update PX6 HA3_rk3399_10.0_ota(20201217) https://www.sendspace.com/pro/dl/rbsz9o
Since update, I have a strange problem. When I turn the accessory to off, the volume bar appears and increases 5 levels.
Example: volume start at 5, turn acc off, volume increases to 10 before power off. Turn acc back on (volume at 10), turn acc off, volume increases to 15 before power off.
My fear is that, should I have music at a high volume when I turn off the vehicle and turn the vehicle back on, I could see voice coils flying past my head.
Since it is an open cockpit (no roof) vehicle, I do tend to have volume very loud.
I have checked factory settings for boot volume - it is turned off.
Thank for any input.
Well, it goes from bad to worse.
I contacted Dasaita and told them I had updated to the MCU and firmware listed in the post above. Both are what is listed as current firmware on Dasaita's website.
They emailed back and said I had incorrect firmware for the Max10. They gave me the following links (direct copy from email):
PX6 10.0 HA3_rk3399_10.0_ota(20201214) https://www.sendspace.com/pro/dl/f3gyol
PX6 android 10 （1113）
https://drive.google.com/file/d/1rO-wBK8rvVZsXT_5IjN3MyuMY00utZZX/view?usp=sharing
So.....
I updated with the first file.
Now the unit has different problems.
Upon removing accessory power, the unit auto launches the default navigation app, and then powers down.
On power up, the default navigation auto launches, followed by an error message that "Zlink has stopped".
This happens EVERY power up.
So, I tried to update with the second file. Update fails claiming that the unit cannot downgrade to this file.
This sucks for me. I told a friend how great my system works and this unit was actually going to be installed in his vehicle tomorrow.
Any ideas?
Try disabling zlink.
I tried everything.
Emailed Dasaita for a bit of help as the problem only happens on the new unit.
I updated both units with the same firmware/mcu. My radio had no problems (been installed for 6 months).
This new radio continues to be a problem.
I re-updated with the same firmware. Several times as each time seamed to give new problems. SDK errors, wouldn't launch play store.
Each time I did select to wipe from the upgrade menu.
Currently, initial power and boot up appears fine.
When I remove accessory, the unit auto-launches the default navigation program prior to going to sleep. If I apply acc power within 30 seconds, the unit powers on and auto-launches Zlink. If I wait more than 30 seconds for full power off, apply acc power, the unit boots and auto launches navigation as that was the last active program.
Is it possible to completely reformat and load the update from scratch?
It just seems odd since I have 2 identical units on the same firmware yet only one is doing this.

If you update android there is an option „wipe...“ maybe you check this.

"wipe data" was selected with each update.
I ended up returning the unit for a new one.
No troubles with the new one.
