Problem with Hizpo radio - MTCB Android Head Units Q&A

Good morning!
I have bought a Hizpo Android radio for my Mercedes Benz Vito w639 (2012). This car haven't got steering wheel or controller for the radio, so I installed it without canbus (as the seller told me) and connecting Illumination and ACC directly to the car, bypassing the canbus.
The thing is that It started working perfectly the first day, but after some time the radio started to do really weird things, like resetting alone or getting looped on the startup showing a black screen with backlight on. Sometimes it works again for 1 day and after that starts again to fail. Anyone knows what is happening? I tried to access the recovery mode for trying a wipe, but I don't know the proper combination of buttons (this radio doesn't have physical buttons, only a reset button).
I don't know if in this forum is allowed to post the link of the website where I bought the radio, but if it's possible just tell me and I paste it.
I have a video of what happens when the radio starts to fail, but I cannot link it already to the post cuz I have less than 10 posts :crying: If you need them for helping me just tell me and I will send you a PM!
Thx for your help!! :laugh:

MOTO HT820 SKIPPING SOLVED! NEW FIRMWARE INSIDE!

IMHO this rates as the greatest Google find ever...well almost. Thanks to rayray987123 from www.motorolafans.com.
I just flashed my HT820 with new firmware to fix the skip problem. According to the info, any HT820 with designation SYN948A, SYN948B or SYN948C inside the headset band may have the skip problem. Mine is a 948A and the flash indeed fixed the problem. The flash instructions I in the attached .RAR file are in English.
NOTE: The headset MUST be turned off. As you are plugging USB cable into the headset, you MUST keep the forward and back buttons depressed. It will not go into flash mode otherwise.
I've been listening to my headphones for the last 30 minutes and they only skipped when I cupped my hand over the earpiece. Sound is as good as the original without the skipping of course. I'm happy!!!!
Flashed my HT820 with this patch succes! Will keep you posted!
Hmmm mine is not recognized, but also is a SYN948D .... any clues?
I'm not sure if you can flash this firmware to any other models. This is for A, B or C only. You may try to contact Motorola to see if there is an upgrade patch for your set.
Shameless bump on the front page. This is not a registry hack...it's new headset firmware and it flat works.
Just did it to my HT820 Part number SYN0948A. Seems not to have completely aliviated the problem completely but its a great great improvement. Where I was getting skipping/chopping every couple seconds I know can through a couple minutes of music. I'll update once I test it out a bit more since it has been only a couple minutes ha ha . Sorry I was just anxious to say Thanks and confirm that it does work. Now I dont know if its just me or it seems like volume is a bit lower and distorst when I put the Media player to 100%. But I dont know if its me like I said. Well I stop ranting and showing my excitement since now I feel like I didnt throw money away on my mda and ht820's since thats one of the major reasons I switched from my sk3
Try the priority256 hack on the registry and see if that doesn't bring it in line. This morning I was trying o listen to Resco Radio and it was skipping all over the place. I did that registry hack and Barry Damn White is coming through seriously clear.
well i have an asian knockoff from ebay... and numbers have worn off on it so i cant tell if i have one that can be updated or not.. when i press down the back and forward and insert the mini-B nothing happens for me, just charges... at any rate i did a reg hack on my 8125 and got rid of the skipping anyway..
First of all, the Asian versions on Ebay are typically not knockoffs. They are the same headphones produced for the Asian market with different firmware. Knockoffs are out there, but if the headphones are coming in the box with paperwork, most likely they are not. I do live in China and believe me it's easy to find the fakes.
Second, the cab that shogunmark posted also has a bad key. Check the registry after installing and you'll find the key AD2P instead of A2DP. That does exactly squat. In addition, the various registry hacks on this board do little or nothing if the firmware on the phone is faulty. Believe me, I used all of the registry hacks and nothing kept them from skipping until I updated the firmware. If a reghack alone fixed your skipping then you have good firmware already installed. The only reason mine were skipping this morning was that the wifi was running at the same time and the priority256 hack gives higher priority to the A2DP dll.
Third, you MUST follow the directions to the letter, or the headphones will not enter flash mode as you plug it in.

First of all thanks for the flame :roll:
second i never said i didnt like my asian version, works great for me, dont care if its asian or a fake or both. Its definitely poorly made, but i dont care, for $50 on ebay after shipping im happy with my purchase.
3rd, i didnt make that reg hack, all i know is that i tried everything.. Mine was skipping every 10-15 seconds when playing music and it drove me nuts.. i finally came across that reg hack somewhere on this board (dont remember the thread) and bad key or not it fixed my problem..
And finally, i did follow the instructions to a T.. next time i will post that i held the 2 buttons down, plugged in the mini-B and "waited 3-5seconds" and still nothing, just a solid blue charging light, no flashing blue light..
so excuse the f*ck outta me for giving my 2 cents on what worked for me, im just trying to help others on this board just as much as others has helped me.
No flame intended. Just be careful what you post. Not that the cab would brick your device, but posting any old cab without knowing its source or what is in it is not what makes this forum great.
I certainly didn't mean to flame you, but was trying to separate fact from fiction. Perhaps I sounded harsh and for that I apologize.
Better?
One last thing; the buttons on the right earpiece are the correct ones. It should go into flash mode if it's the real deal. Again, sorry for being assuming, but I don't give up easily.
This ain't working for me either. I can't get it to go into flash mode. I turn the head set off, hold the buttons, plug in the cable, and wait . . . and the light just stays on. Nothing changes when I release the buttons.
So, if it worked right for you, did the lights turn on as soon as you plugged in the cable, and did it start flashing before or after you released the buttons?
I have PN SYN0948A so blah on me.
The light will not begin to blink until it has been plugged in for a few seconds. Keep the buttons depressed until it does. Once again the buttons on the right side earpiece must remain depressed while the cord is inserted. As long as the lights are blinking, you can run the .exe in the patch and just follow the instructions from there.
I'm certain it does work. However, this seems to be a problem with more than one person, so I have no idea if its the way you are doing it, or the headsets.
Well I was able to do something that made the right light slowly turn on then off again. And now lights aren't working reliably (ie the left light flashes like normal when I turn them on, but the lights stay dark when I plug it in to charge). It doesn't seem to respect me pressing both right buttons to turn the lights on and off.
I've tried it with the headsets on and off, tried it with various USB ports, and the like. I'm pretty sure I've done it the right way at least once, but no dice.
Thanks for putting up with my fumbling though.
I guess you can add me to the list of failures. I can't get my SYN0948A to go into the flash mode. I've followed the instructions but the lights do not flash at all. Is there any other way? (hopeful)
I guess you can add me too!!! (SYN0948A) ;-(
I just flashed my 48A with the firmware provided above. Great Job!!! No more skipping. Not to mention, the range of the headset has increased by about 5 metres. Dont know if that was supposed to happen :lol:

Glad I could help Nerker.
If you see new hardware added (Ht820) when you attach the headphones, they are in boot mode whether the light is flashing or not. Make sure you are pressing the forward and back buttons (NOT the volume) and the power is OFF when inserting the USB cable. (all caps for emphasis, not screaming, lol)
Thank you so much for posting this. I followed the instructions and my headphones (syn0948a) work flawlessly. No more skipping!!!

Hermes No Audio!

Hey Guys, love the roms so far... But I've run into some problems. I loaded Josh's Hex Rom, and now currently the hardware buttons on the phone, (pickup/end/Softkeys) and the Audio is gone. I reloaded to the At&T Default ROM, and reloaded for another rom... However the AUDIO is still gone on BOTH AT&T and Josh's Winter ROM.
Any Ideas?
try installing s2p (slide2play) and see if its in headset mode...
I have also heard of the connector for the internal speaker getting disconnected after getting dropped.
Thanks for the input, I verified and could used the earphone so I took them out tapped the phone on the desk, and low and behold it works!
Thanks Guys
Hopefully that fixed it! But, if it does it again, it might be time to look into disassembling it to see if a connector came loose. I haven't had mine apart yet.
Well I fixed it, when I opened the phone up and the internal speaker was disconnected. However now is there a reason why my call buttons down't work (hardware ones)? or do I need to open the phone again?
it's possible you disconnected something else? I service copiers and have done that to myself before!
happened 3 times to me now: internal flat connecting to speaker disconnected.
Annoying. you have to open the hermes, luckily connector is not "far away". Easy to see and fix

I don't think so, this time I went all the way down to the keypad (LCD) and nothing was disconnected. However, some of the buttons periodically work. Which is strange. Anyways We'll see

Good luck! I'll be curious to know what happens.
I dread the day that I feel the need to open my hermes. I'll probably shed a tear, man I love this phone!
This is what I know as of now.... The buttons still do not work however the back light does. Which is strange... :S. Later today I will open my Hermes for the 4th time and see whats wrong with it. I will this time record a video and post it up so I can get more insight on whats wrong with the device...
Anyways
I'll post again soon!

Volume button + WiFi Problems + Touchscreen no reaction + Board computer problems

I have some questions. (Copy from the old thread)
1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.
2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?
3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.
4. Since a few days if i turn off the key normally all lights form the radio and display shut down. Additionally board computer shut down too after a few seconds. Now the light from the dvd tray is on and board computer too (after a lock from the car too). I dont know why but I don't know if that is so good (Battery).
All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom? That is really crazy, because it's only since a few days. The days before it works perfect.
I have JY 2.73 with the Malaysk Rom from September (1024).
Thanks
Update: Now i installed 2.59 JY and tried again. WiFi will always gone with no bars. So i turn off and turn on again. At the most cases it works. But the problem is here again. The same with the touchscreen crash. 3G doesn't work. always no bars.
So the previous MCU doesn't work again. Maybe a software error.
Could you please try to measure the voltage alignedto the HU while you encounter those problems? I rellay mean at the radio side (so not at the battery poles).
Such issues could be lack of voltage. If not and flashing does not solve it could be a defective unit.
Just to ensure: You flashed Firmware AND MCU? AM I right wit this assumption?
If not: Try to flash a new ROM first (probably try Malaysk ROM)
Btw: Moved to Q&A

Thx for answer. How can i measure that? Do you know which cable it is? And if the cable shows not the 12V? What can i do to fix the problem?
Sure. I have Malaysk Rom and the MCU JY 2.59.
you would have to get amulti- or vooltmeter and attach that between plus and ground pins at your HU.
If you don't know how you should eigther try to follow another way first if possible or ask someone to do it for you (it's electrics)

Thanks. I ordered a multilmeter. Maybe it's the battery. At the moment the car works really hard if I start it. The radio takes so much battery but the radio is off. So that can be the problem.
low voltage can cause many weird problems but you have to know a new battery might not solve your problem!
If you have low voltag while the engine is ruunning then you have a different problem. eighter there is a connection issue somewhere on the path the energy takes from battery and generator to the HU or your generator might have a problem. But that is open to check when we know if it really is a voltage issue.
Hi,
i'd like to give you an update for my problems. Since the last days I have the problems, that my car didn't start. Now we see, that the battery is nine years old. Now I charged the battery (tomorrow I'll get a new battery) and the first test shows WiFi works for 3 minutes. I know - that's not a lot, but I only can try if I have the new battery. 3G doesn't work - always the same. But that's not so important for now.
At the moment I don't have the volume error. I will test it, If i have a longer car drive.
The problem with the touchscreen is actually. Since a few time, after few minutes the touchscreen is bricked and I see the points that i touch it, but I can't click anything. If I touch ten times, twenty times or often then radio shut down and shows the boot logo... forever... it doesn't boot again. So I have to make a hard reset.
And the last point with the light board computer and the light dvd slot after plug off the key is actually too. It don't shutdown the lights on the standby time from 10 minutes (set it to 10 minutes). I know now, that I can shutdown it completely if I press the volume button for 3 seconds. Than it's turn off. So it's a setting problem from the firmware?
Today I plug in the key - nothing. Radio doesn't start. So I looked behind the radio and saw, that one thin cable is not in the wiring harness and I can see the wires on the cable. So I tried to put it in the wiring harness again. I hope it works longer now. I wrote carjoying and ask for a new wiring harness. Maybe all problems will be fixed, If i have a new.
Hello again,
now I've got a solution for the wifi problem. I've tried to connected wifi - i Known that doesn't work only few seconds and after a few seconds it shows 0 bars on wifi... now I disconnected my 3g stick and LOOK it works... full bars, no losing connection. I connect 3g again and the same problem after a few seconds.
So th3 3g stick (E1750 from Huawei) makes some problem OR the usb cable?
Huawei E355 also not working. Same connection problems with malaysk rom MTCD
Any suggestions?

Updating MCU via PC?

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

PX5 stuck showing warning image, buttons unresponsive.

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.

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.
