FM Radio has no signal at all? - MTCD Android Head Units Q&A

Have a new China headunit with android 7.1.2 and first there was no FM radio. Searched XDA and with password m123456 got into factory settings and there the radio stood OFF?? Changed it to ON and after restart it was there. But there's no signal, no sound, nothing. Anyone ideas?
Also, this is a monitor with no buttons. How do you get in recoverymode when there's no on/off button? I only have the reset possibility (little hole on the side of the monitor).
Info headunit; see attachments

Did you select your country as well ?

If you mean the region for the radio in factory settings, I did.
If you mean region in Android, like date and clock? Somehow I only can set it manually. If I choose automatic date/time it stays on Chinatime?

And do you have your radio antenna Installed?
For going into recovery:
Press reseat button until you see flashing the button lights..(approx 25sec)
Release and press again until see your nougat logo.
Release and wait for recovery menu

Radio antenna, isn't that the microphone? There's no separate antenna plug? See https://www.seicane.com/android-hd-...hd-1080p-video-steering-wheel-control-s018848
Recovery; press reset button until you see flashing the button lights.. (approx 25sec) >> what button lights flash? There are no buttons

WOW would you look at that unit !! Does it drive the car for you too !!?? lol Judging by the pictures it must be on the box somewhere but when zooming in I cant see if/where it would say ANT..

Yes, looks impressive, car almost drives itself . Works very well, nice touchscreen, only no radio signal. Also the steering wheel buttons can't be changed. But they work well, although would be nice if I could customize them.
Sorry to say, but there's nothing on the box for a Antenna. The only thing saying something about an Antenna is on the big plug/connector witch connects to the original radio. On the attached picture there are 2 pins ANT. Does it use the original car antenna through the connector of the original radio?

It says that it syncs with the cars bluetooth have you been able to get and kind of sound with it ?

Your new unit don't have radio, the radio is from stock unit, you must have to connect your new unit in conjunction with the stock unit. And there is a "app icon" that switch to original menu and there's your radio.
You just change the stock screen for the new one and connect the original cable of the stock screen to the connection labeled car lvds

Cid6.7: yes, bluetooth works fine and the sound is good!
Hugovw1976: I did not know there wouldn't be a radio in Andorid. I can switch between stock and Android. But, when I go to Android the stockradio stops. The only way to go from stockradio to Android is when I push long the GPS button on the steeringwheel. Stockradio keeps playing and GPS (IGO) starts on the screen. I can go back to the radio but then the GPS stops.
Are you saying there isn't even a FM receiver in the central box?
Oh, and thanks for the replies, now we are getting somewhere.

I install a similar unit (the central box is the same) on a Audi Q3 an there's no radio.

Thanks, that makes everything clear. Do you have experience with the steering wheel settings? When I turn it on in the factorysettings and restart the system it comes up in Android settingsmenu. When I start it up I get a black screen?

When in recovery mode how to scroll in the menu?
Or does the touchscreen work in recovery mode?

Hi, can't get into recovery.
Do I have to press reset button when unit is off or on?
Took power cable off, pressed reset button, put power cable on and followed your instructions. Did not work.
Please advise.

Solved:
First in the systemmenu there was no way to activate developer settings in the normal way. Solved this with Total Commander.
Bought a USB cable, in my case A to A. Couldn't get in because USB standard is set on 'Host' and it is not possible to connect with a OTG cable.
In factorysettings wrote 'abdon' and immediately the headunit came up on the with USB connected Windows PC .
On PC choose to see the files. It works!
Downloaded latest SDK. Opened commandprompt and changed dir to the SDK directory.
Put in command: 'adb devices' (without the quotes) and there it was!!
The command that worked for me to get into recovery is: 'adb reboot recovery'
Only problem left: fastboot is not working in recovery mode. I think the problem is that the USBconnection goes back in Hostmode when booting into recovery. Anyone now how to solve this?

Make sure that you are allowing the tablet to search for devices - in the top right corner of the setting on the bluetooth page. When I first tried connecting my BT headphones, I think by default it showed only visible devices. Not very intuitive IMO.

Need help with debricking a MTCD KGL unit.

Hello,
So I have a bricked KGL MTCD unit. During the update process with Malaysk's most recent FUSE 5.1 ROM, the ignition was turned on, causing the screen to briefly go black, then back to the Android robot with the update status bar, and a second later the unit died.
I read in another thread that I started regarding this that it is possible to debrick an Android headunit using drivers and the RK Batch Tool. I downloaded everything from the Rockchip.nl site.
When the unit is hooked up to power only the button lights light up and that's it. No response whatsoever.
I tried hooking it up with a male-male USB cord to my Lenovo T410 laptop but there is no response from Windows regarding recognizing a USB device.
I have tried every USB port. I've tried both ports on the device and still nothing.
I have tried USB only and external power too. Nothing works.
I have also tried connecting a different, 100% working KGL unit. I hooked it up to power, then tried both USB ports and the computer doesn't recognize any.
Can anybody please tell me how to restore this thing?
Do I need to install the drivers into Windows first? I thought my PC would surely recognize the device and THEN ask for drivers. How do I go about installing them?
Thanks in advance
EDIT!!!!!!!!!!
DEBIRCKED THE UNIT WITH MALAYSK'S METHOD FROM THIS POST http://forum.xda-developers.com/showpost.php?p=67184851&postcount=50
Unbricking MTCD GS
My MTCD GS RK3188 800x1024 Android 5.1.1 radio in my W220 Benz is also bricked.
It came with ROM v. 1.34 I think. So I flashed the most recent OEM ROM I could find (I think v. 1.73) through Settings/About/System Upgrade, hoping to be able to root the radio so I could use Titanium Backup.
Everything went swimmingly and all was good with the world.
Except I still couldn't root through recovery. So I tried to flash Malaysk's most recent GS pre-rooted ROM.
About half way through the process, the screen unceremoniously went black.
Now the radio is bricked. Only the button lights illuminate.
I tried several methods of rebooting into recovery, but nothing happened.
I read the HuiFei page, searched the XDA forums and the Internets generally and still could not find a solution.
I connect the radio to my computer via USB and tried to use the RKTools program, and still no luck.
I hope I missed something somewhere in my searching, so I beg of you: If anyone out there knows how to unbrick this unit, please, PLEASE share your knowledge with me.
Thanks in advance.
I just tried to update my Xtrons unit from a firmware on their site. Update finished 100% and upon reboot the screen was just black!!! There has to be a way to unbrick these. No way am i tossing out a $400 unit! I have a PF73AA4A which i believe is a RK3188 quad core 16g. Please help!
Solved! Mtcd unbricked!
@NaviPR, @shawndak and anyone else suffering the same fate:
I quite accidentally figured it out! Here's what I did (sorry, I tend to over-include information)
It started when I found a link on the Android TV Box forum about debricking RK3188 TV boxes. There was a process where the NAND was reset and then set to Mask Mode by shorting pins and pressing buttons; then the firmware was flashed with RK Batch Tool.
So I loaded RK Batch Tool and driver onto my Windows 10 computer, brought the head unit in and removed the bezel to expose the SoM.
Sadly, this SoM used a different NAND chip that did not have visible pins. So I started messing around.
At first, I couldn't get the PC to recognize the HU after trying the standard recovery process. Finally, out of frustration and without expecting any results, I tried one last thing. These are the steps:
1. Download Rockchip DriverAssistan v.4.4 and RockChip Batch Tool 1.4 zip files.
2. Extract files from each into separate directories.
3. Run Driverinstall.exe.
4. When done, run RKBatchTool.exe
5. Load your desired firmware into RK Batch Tool by pressing the dots button after the "FW Path" field.
6. Power the HU by connecting the 12V (yellow), ACC (Red) and ILL (orange) wires with 12 volts with a benchtop power supply. (Orange isn't really necessary, but it made me feel better to see the lights on.)
7. Connect the HU to the computer with a USB cable.
8. Press and release reset and wait 10 seconds.
9. Press and hold the power button for 10-15 seconds as if you were turning it off normally.
10. Release the power button and within 1 or 2 seconds press and hold it again for another 10-15 seconds until you hear your PC indicate it's loading a driver. At this point RK Batch Tool should show a connected device and the number 1 will light up blue.
11. Press the "Restore" button on RK Batch Tool. The number 1 will flash yellow while it uploads the firmware.
12. When done, repeat steps 8 and 9. The splash screen and logo screen should show up after a short while.
13. After unsuccessfully waiting a long time for it start the launcher, press reset.
14. Wait for HU to boot up and go into whatever flavor launcher you are using.
Two things to note:
1. It was helpful using a power supply with a current meter so you can actually see the current drop that indicates it's ok to release the power button and press it again.
2. When the firmwareI sideloading completed, RK Batch Tool showed a red error message "<Layer 2-6> Download Firmware Fail." Do not worry. Disregard the error message and continue with the steps.
I hope this works as well for you as it did for me.
Let me know and feel free to contact me if you're having trouble. Good luck! :laugh: :laugh:

Thanks for the help, I followed your guide to the letter but unfortunately it didn't work.
Here's what I did:
- laptop runnin' Windows 7
- tried both USB ports in the unit - 3G and USB
- installed the drivers, installer said everything went fine
- I'm using a tabletop power supply which is working fine
Here's what happens:
I power UP the HU, doesn't matter if I plug in USB or 3G.
This unit is totally bricked. Only the lights in the buttons work.
I press Reset and RELEASE IT right away. When pressed the lights go off, upon depressing they turn back on.
I wait 10 seconds, I press hard on the power button, the lights go off but come back on around 10 seconds later.
I depress it, lights go off, I press hard again within a second or two, lights go on, and then nothing.
I've done this many times and nothing works.
I started frantically pressing the Power button out of frustration and I think I heard the standard "new USB device connected" sound of Windows 7 ONCE, but nothing really happened.
Wife has the car at work right now so cannot try this until later. My unit is a MTCB. Do you think your method will still work? I saw the RK3188 Android TV Mask mode as well but didn't want to risk it since the person i bought it from is willing to attempt a repair/replacement. I found the proper MCU GS file and will flash that with a 5.1.1 Fused Rom so i can use the full internal space! Will report back if all goes well. Thank you
Also noticed i cannot flash a MCU alone with the batch tool. update_5_1_1_FUSE_1024X600_RK3188_04_MAL_06_09_2016_MTCB This is the closest firmware I can find that may work for my MTCB GS unit. Will it work?

@NaviPR
Sorry it didn't work. I'm encouraged if in fact the computer chimed.
First try the same thing, but hold the buttons longer, e.g. reset 10 secs, power 20 secs. after reset release.
Also, I did 2 other things before the hard off/on process but didn't think they were related. Maybe they are:
A. Try to get into recovery by:
1. Turning 12V on while holding the power and reset buttons.
2. After 5-10 seconds, release the reset button and keep pressing the power button for another 10-15 seconds
3. Release the power button; within 2 seconds press it again and hold another 10-15 seconds; release
4. If no boot logo shows up after a minute or so, try the hard off/on procedure.
B. Reset the NAND chip (I found nothing to confirm this is how it's done. I just assumed.)
1. Remove the front bezel to expose front of SoM board. Be careful not to damage the ribbon cables.
2. There are 2 pairs of silver test-point looking dots on each side of the NAND chip (see picture)
3. With power disconnected, short each pair individually.
4. Do A again. Then do my hard off/on procedure, holding the buttons longer.
Again, the key is to get the PC to chime and RK Batch Tool to show a connected device.
I don't know if the difference between Windows 7 and Windows 10 had anything to do with it, but you may want to consider it. Maybe try an older RK Batch Tool version with Win7. Also, try a different USB cable.
Hope this helps.

@shawndak-
I'm sure the MTCB HU uses a different SoM board. With any luck, it's the board that has a NAND with exposed pins like the one in the RK3188 TV Box unbrick thread. If so, try the following procedure:
-Reset NAND by shorting pins 5&6.(See picture)
-Open RKBatchTool.
-Press and hold Reset / Short pins 7&8 / Plug in USB cable at same time (requires 2 hands or contortionist LOL)
-Release Reset after device appears in RK Tool.
According to the thread I borrowed this procedure from, the HU should only be powered through the USB cable. However, if it doesn't work that way, try connecting it to a separate power supply and turn it on after plugging in USB cable.
Good luck!
PS. Sorry, I don't know if the FUSE firmware will work on the MTCB. @Malaysk has separate sections for MTCB/MTCC firmware and MTCD firmware, so you may want to confirm that you sourced the firmware from the correct section.
PPS. I want to credit the author of the TV Box thread, but I can't find it again.
UNBRICKED!!!! I hooked up the laptop with the drivers installed and batch tool open. Loaded the firmware. Then i did this exactly,
1. Turning 12V on while holding the power and reset buttons.
2. After 5-10 seconds, release the reset button and keep pressing the power button for another 10-15 seconds
3. Release the power button
Boom computer recognized the device. I pressed restore and it flashed the unit in about 5 minutes. Then it booted up!!!! Feeling invincible I loaded the 5.1.1 rom over the 4.4.4. Everything worked! I have Android 5.1.1 on a PF73AA4A MTCB GS MCU!!! So when are we getting Marshmallow? lol Nougat? The Fused rom is amazing, so much room for activites!!! Thanks everybody!
@shawndak Tried your method, doesn't work.
Try a different computer. You said a male to male cord, are you using a usb to usb B (mini) and plugging it into the front of the unit?
Make sure you have the most updated tools as well https://androidmtk.com/download-rockchip-factory-tool. You have to install the drivers!!!! They are located at the bottom of that page!
@shawndak The unit doesn't have a front USB, only back USBs.

Whats the model? Can you send a link or a picture?
@shawndak It's just a KGL model for a pre-lifting W203 Mercedes-Benz without a front USB.
I've already unbricked that one + two other units using @Malaysk's other method http://forum.xda-developers.com/showpost.php?p=67184851&postcount=50
It worked 100%, although I had to use a USB drive.
All you have to do is create a recovery card using the program from the post, get a USB drive, load some factory firmware onto it, then insert the card into the GPS slot and the pendrive to the USB. Then, if the card initializes recovery but gives you an error message, remove it - it will go into regular recovery mode - and update from the USB.

Very interesting. Perhaps slow format those cards and attempt it again. If not try a warranty claim with whomever you bought it through. Good luck!
@shawndak I don't think the card is at fault here.
Anyway, read Malaysk's guide and follow it to the letter. In case your unit gives you an error message saying that you have to remove the card, do it and you will be dumped into regular recovery mode with the USB stick still plugged in. Just load the firmware from there.
Like I said, I've unbricked 3 KGL units using this method.
@NaviPR
Did you try both of my alternative methods?
It shouldn't matter that the USB port is not on front other than having to remove the HU to access the rear ports.
Admittedly, I also have a W203 so I know it's not as easy as removing the HU from a W220.
However, it sounds like @Malaysk's method is better because you don't have to remove the HU, etc. Is that right?
Wish it popped up during my search. Would have saved me a lot of time if it worked.
Nevertheless, since @ShawndaC and I were successful with my solution(s), maybe yours bricked under different circumstances.
using malaysk technique I can fix 60% of bricked devices I get
another 40% need the hardware repair and parts.
I repair many head units daily

HA 10.2" MTCD black screen -- with flowers...

So I started my CX-5 about an hour ago to be greeted by a black screen full of flowers. Literally. No idea why. This happened one other time, and it seems as though once it powered completely down, it comes back up fine. I have the timeout at 2hrs, so I have to wait quite a while to see if it's going to be ok.
I tried to reboot the unit by holding the reset button down, but all it does is put it to sleep. Actually, a short press caused it to mute (literally displays 'mute' on the display), and a long press puts it to sleep. Tried the press it till it goes off then release, then press again -- doesn't do anything but wake the unit up again.
The steering wheel controls all work fine. When I parked it last night I had the radio playing, and it was still playing when it started with the black screen. Volume and fwd-rev buttons on the SWC work fine. None of the capacitive buttons on the LCD do anything except home and power. Power puts it to sleep. Home displays the launcher screen (Car Launcher Pro).
If I press any of the app buttons in car launcher, they send me back to the black screen. Pressing the speed in the launcher switches to the trip display like it should.
Anyone ever seen this?
Anyone know how to actually reboot the thing short of pulling the fuse (if that would even work)?
The car has resistive steering wheel controls and *also* has a canbus decoder to tell the Bose amp what to go do with itself. I didn't actually have to use the KEY1 or KEY2 - I assume that the Mazda ISO adapter that they sent has this built in but I dunno.

That's happened to my MTCD a couple of times and seems to be when Android's user interface hasn't loaded properly for some reason.
Pushing a paperclip into the reset hole until it reboots normally fixes it for me.

Reboot with a paperclip as other guy pointed.
Your can bus not only plays with Bose amp....it gives you the reverse signal for the Camera as it is coded by can bus.
You have nothing to do with cables as they are properly wired for your installation

Home displays the launcher screen (Car Launcher Pro).
If I press any of the app buttons in car launcher, they send me back to the black screen. Pressing the speed in the launcher switches to the trip display like it should.
Anyone ever seen this?
Anyone know how to actually reboot the thing short of pulling the fuse (if that would even work)?
The car has resistive steering wheel controls and *also* has a canbus decoder to tell the Bose amp what to go do with itself. I didn't actually have to use the KEY1 or KEY2 - I assume that the Mazda ISO adapter that they sent has this built in but I dunno.
Running MCU MTCD HA version 1.81

I got the same screen in my HU but only when car launcher is installed. If you remove the launcher that screen will not show again. Maybe is an issue with the car launcher with the units. I am using an MX (witson) version 1.93
I thought it might be car launcher. I haven't had any issues in quite a while though.

HU wont start up

Hello. Hope this is the right place to ask this.
I changed a setting under "factory setting" and now the HU wont boot up. The setting was "Default power status" changed it from on to off. I also turned of the canbus under factory setting and when i wanted to exit i needed to reboot and then it never booted up again. It might boot up but there isnt comming anything on the screen.
I really hope that someone call help me fix this.
My unit it this on. Bought on iceboxauto http://www.iceboxauto.com/opel-astra-j-2010-2012-android-60-b5754

In my px3 i set default Power status in "off" and i have no problem.
Did you try to hold Power button (about 15 sec. till blinking led lights) for resetting HU?
Sorry for my bad english

There are no fysical buttons on the unit. I have tried to hold the power button on my dash board but stil nothing happen
You can try:
1) reset button (if there is It, you can check under gps slot)
2) unplug the connector or turn off the fuse box to reset the hu

Press reset until you see light blinking (15-20sec). Release and press again reset until marshmallow logo appears...release and you will enter into recovery menu

I talked to the seller today and he told me to press the reset button next to the gps slot. When i told him there isnt anything behind the hole he didnt know what to do. Great :silly:
I got my unit up running again. Because i dont have any fysical buttons on my unit and i ****ed up the canbus setting the only way to wake the HU up again is to disassemble the screen and on the board there are some connection where you can solder wires to. One of them is "key1" and when i put i wire from that to GND the screen turned on. There is also a "key_rst" thats for resetting the HU. There isnt any wires on those so later i will make it on my own so i dont have to disassemble the screen if i **** something up
Hey , I did the same mistake with "default power status". I can get into recovery menu, is it enough to wipe the firmware(not MCU) of the device?
Thanks
Made the same mistake with this setting.
If I press and hold power button after about 15 seconds button lights come on and then flash. Keeping hold of button and lights stays on but screen is doing nothing.
Reset button causes lights to flash but then go out. Again nothing on screen.
Mtcd px5 unit.
Seems like something is going on because a message of 'other' appears on car standard fit display next to clock which is what generally appears when head unit was working.
Maybe there is combination of power an reset needed.
Eventually into recovery press and hold power button until lights flash then let go and press again. Took a few goes to get timing right. Then key was that I had an exported MCU conf file so I reflashed MCU with this so default power setting was back to being OK.

I have the exact same problem, I changed the "Default power status" in factory settings to off and after the reboot the system would not come back up. Odd part is if I wait a few minutes my phone will still connect to the radio via bluetooth. Seems almost like only the LCD is not powering on. Since I can still get to recovery would it be possible to get a copy of your MCU conf file so I can try and reflash? My unit is a KGL and I currently have the 7th Floor mod MCU installed on the radio. Any help anyone can provided would be much appreciated.

Never mind I was able to grab the modified DMCU.IMG KGL file from here, and then add the DMCU.CFG file from here, then throw them on the root of my GPS SD card, then boot into recovery and flashed the MCU. After the reboot the screen came right on. I just had to go into factory settings and make the needed changes for my radio.
I was stupid enough to did this same to my HU.
All because it draw 0.25A when in slip mode (ACC OFF).
I try to different options to drop power consumption and change this option in process.
Off course I have brick my unit. Any way to recovery it??
Dont have any hardware buttons no GPS slot. How to reset this unit??
Any ideas??

Suggest having a read through links in my signature. If your unit, which you havent said what type it is - is drawing 0.25A in sleep, then that's a problem.

My Unit is MTCE GS PX5.
It was unit with out radio module (xtrons for Freelander2) so i solder one on board. In process have to change MCU from GS to KDL to get it work. Then when unplug ACC cable from 12V radio going to sleep and after few seconds will constant draw 0.25A around 3W. I cant remember how it was before but previews owner sold to me because of battery draining issue. I believe its bit much as will drain car battery quite fast. So i try to find a way to eliminate this flaw. In order i change option "Default power status" to off and since that my screen is blank. Looks like radio is working as Bluetooth is broadcasting. I try to fiddling with it for bit more if not probably only option is to program STM32 with ST-Link STLink V2 Programmer. Maybe any ideas how to reset this settings.
BTW bit stupid to put option that can brick you radio in easy accessible place.

Just little update. I already order ST programmer and now wait for delivery.
When i have close look (and from different angle) on radio screen I can see that radio boot to OS and first page pop out. Just screen back light not working and touch as well.
Also Usb is switch off so no keyboard can be connected. Only option is to reset this setting but dont know how or programming MCU.

Job Done.
Radio back to live by programmed MCU using ST link.
Still problem with drainage but already order new MCU and will try to replace it as at the moment STM32 is very warm when on STBY (ACC OFF) so probably there is a problem.

Bricked Witson PX3 MTCD >>Solved<<

Do you know how can I enter recovery / reinstall firmware on a Winston PX3 without any buttons? just reset.
The unit is made of Opel Insignia and uses the car button. The power power button only switches the screen on / off and nothing more.
Is stuck at the lollipop logo without anything else.
I tried all the method here... reset, keyboard without any luck
RK tools not working since is not seen by the laptop
Bootable SD, same... no luck.
Thanks in advance
I also want to know that, never find solutions at this time.
I have same car with same head unit, do you have a good radio reception?
Read here and tell us if it works ... on my witson px3 android 5.1.1 works this procedure to enter in recovery... good lock

Solved after taking out the unit.
The trick with power button does not work since on Insignia access to the power radio buttons is via canbus interface. Power button only switches screen on and off when not in Android... nothing more.
So solution:
Is easier if the unit is not mounted in the car, I have not tried to enter recovery after a reset, but maybe I will try sometime.
1. Disconnected all power from the unit... ACC & BAT disconnected
2. Prepared 12V power supply with on negative and two positive connectors
3. Connected negative to GND & one positive to BAT
4. Connected USB keyboard
5. Press right ALT (ALT GR on some keyboards) and PrintScreen
6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
6a. Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
7. The boot logo shows (Lollipop...etc) and after a few seconds the unit reboots itself
8. Release right CTRL & PrintScreen and continue to repeatedly press on E.
9. The Recovery shows on screen.
Sweet success at last.
I put a USB stick with Hal9k room and selected install from USB and clean... waited for 15-20 minutes and everything fine.
Mounted the unit in the car after switching to MicroG and configuring apps.
Hope this helps others who have problems getting into recovery.

Hi,
Found solution, described in the previous post.
Reception is good. I had also a power amplifier mounted but did not improve reception futher so got rid of it.
Hal9k ROM with MicroG is much faster than stock one.
