I bought a while back a Chinese MTCD PX3 'ouchuangbo' unit with as MCU: MTCD_HLA_V1.88_1 running on android 5.1
I then upgraded this PX3 system with a PX5 board from wilson and installed this on my system, it was a matter of plug and play and it works fine, the unit is now working for several weeks on the new PX5 board using the Malaysk PX5 rom on android 6
Because the MCU is an older version I contacted the seller and asked if there was and update available for the MCU.
It seems 'ouchuangbo' indeed had a newer MCU version available with number MTCD_HLA_V2.46.3 but they answered to me the following after i asked if i could receive the update files:
'Our engineers said: If you want to upgrade the MCU software, you need to upgrade the main program at the same time. If the operation is not correct, the upgrade may fail. If the upgrade fails, you need to return to China to repair, all costs you need to bear. Because our main program and MCU software are updated. While upgrading the two software, the system more stable. Our software is android 5.1. '
I also received from seller the 2 following files: dmcu.img (189kb) and dupdate.img (850mb).
Is his answer true and can i NOT update my MCU with the current PX5 board with this new MCU update safely without flashing the ROM aswel?
Must i first place back my old PX3 board before i update my unit?
Or can i only update the dmcu.img running Malaysk PX5 ROM and keep the current ROM without risking to brick my unit?
Who can advise?
You can safely use dmcu.img without flashing dupdate.img.
Before updating MCU, make a backup of MCU config

Thx.
Any idea how do make a backup of the mcu config?
Go into factory settings and you Can find the "export settings" button

Also, maybe search thru some of my recent threads. I have accomplished the same for my mtcd-kd unit with some pretty interesting experiences. If you have a 1024x600 unit, you should have no issues.
Use the dmcu file by itself, do not flash the PX3 dupdate image on the PX5. At this time we have franken machines. Use the dMCU file from your manufacturer or known compatible unit and the PX5 dupdate image of your choice. However, I would perform any updates individually.

In factory settings you can export mcu.cfg
To re-apply the settings, just put the mcu.cfg file on the SD card with the mcu.img. Or, once mcu has been upgraded, you can remove the mcu update (.img) from the root of the SD or USB Stick card and apply the config (.cfg) on the root of the SD or USB Stick separately - by running the 'upgrade MCU', it will see .cfg file and apply it.

IS this a safe operation? I can see restoring the dmcu.cfg for the same version of MCU Code that was originally installed. HOWEVER, I can see how an application of a dmcu.cfg file may not function appropriately if a different version of MCU Code is in place.
Anyone have a 100% answer on this?

I upgraded my originally JY PX3 MCU to HA after installing my PX5 board (see cross-compatible MCU thread.)
Unfortunately there are no guarantees in this risky process.
Your concern appears to be around factory settings/dmcu.cfg - to mitigate this risk, document all of the settings as they are found in the factory settings menus. E.g. "knob mode", volumes, customer version, radio, bluetooth type, hardware keys.
I had to manually set some of these factory settings after applying a backup from my Joying config, as it appears that the vendor mcu contains some configuration which takes precedence.
Good luck.
i got no luck.
When i started the update it fails with:
do not Match mount /mnt/external_sd
Installation hctextcfg aborted.
do not Match mount /mnt/external_sd
Installation mcucfg aborted.
do not Match mount /mnt/external_sd
Installation mcuimg aborted.
updata fail!
System works further normally, but the mcu version is still the same.
Contacted the seller and they insured me it was the correct version, they would as the enigineer on monday.

Hi, I have MTCD MCU HLA unit and I do not get firmware or MCU from the vendor, you could send me the updated files (firmware and MCU you have).
my email: [email protected]
Thank you
Is it possible to make a full backup off the mcu? I mean a mcu.img. I have the mcu.cfg already.
Also got the update of a HLA PX3 unit with 7.1 from the manufacturer, nupdate.img and mcu.img.
But to be sure I want a backup from the original mcu.
Any updates here? I have also al HLA unit, a PX3 7.1 than I have upgraded with a PX5 board. I would like to update MCU...

Hi guys, during install of a HZC 2.58 firmware on my xtrons td101as (which had an older HZC version which I replaced with a GS version) I saw that there were 4 android files updated - so it seems that there are dependencies between android rom and mcu firmware version - and now I get the "version unmatched" message on my screen (but everything seems to work fine?)
So when I first install a new mcu firmware and then (after that) install an android rom it would override the changes made by the mcu installation?
What is the correct installation order when installing both android rom and mcu file and do I have to re-install mcu after updating the android rom?
Greetings
Detlev
First, I'm not an Android expert and I can't answer your question...
But I've never heard of dependencies between the 2 upgrades. If it's true, it's absolutely something worth to investigate!
You know what are the file changed?
I'm waiting for experts answer too.

Set factory settings after updating MCU. Assume you documented your MCU settings before changing MCU to a differing manufacturer? Did you not realise that MCU update contains manufacturer/model factory settings config?
Unfortunately I don't know, what files where updated - there was only a message "Updatin android files 1/4"
I always installed without mcu config file and did the settings manually after install.
I installed the "HA" 2.59 mcu file (corresponding to the HA android file): "Version unmatched -01
Then I installed the old "GS" 2.56 mcu file - NO ERRORS!
What I don't understand: thougth the "Version unmatched -01" error was shown on the screen EVERYTHING worked without any problems? Strange ...
Now I do have a working system with HA 2.59 android version and GS 2.56 mcu - curious that the original "HZC" mcu file did not work too (I bought it with "HZC" mcu file installed, version 1.4 or so)

Hello everyone,
I would like to know if it is possible to somehow "download" the Android software from a MTCD unit?
Like how you use update.img to update the software, except in reverse. Is there any way to download a copy of the system image, preferably in a convenient, usable update.img form, from a unit?
Thanks in advance.
I don't know the answer, I also want to know!
+ The same question but for the mcu.img

HA ROM from dasaita - what's that? Never head of a manufacturer like that?
What I meant was is there a possibility of downloading the ROM from any Android MTCD device (KGL, KLD, MX, GS, whatever), in a re-usable form (such as update.img) to be used on another Android-based device?
Yes, HA has an OTA update function for ROMs but I am not sure if it works. When the last update came out I've tried to update but it showed me that there is no update available. So I had to update manually. I am not sure if it didn't work because I have a GS with HA ROM, if the update wasn't published via OTA or if this function isn't workning yet because it is new.
OTA MCU updates aren't available.

TitaniumBackup once you get it set up you can create a update.zip
As for the MCU when your done fixing your factory settings before you exit his export

Hello,
I have a car radio on the Android MCU system version MTCD_KGL_V1.53a_1 compilation number rk3188-userdebug 27052016.
Can I update to a newer version of android, because it is 5.1.1 now?
On the forum I found MCU updates for KGL v.2.83. Where can I find a ROM for my radio.
I tried to update the MCU, but unfortunately I'm making a mistake. I do not know what I'm doing wrong. I downloaded the MCU from the site
https://forum.xda-developers.com/showthread.php?t=3246386
I copied to the card and changed the mcu.img file to dmcu.img. Unfortunately, it lights up the error.
I do not know if I should update the ROM first and then the MCU first.

I have read that if you upgrade your android system to the newer version; something about the GPS maps will no longer work. Not sure but you might want to look for that.
I have the same system A-Media Auto, MTCD-KGL_v1.53a_1
I found a newer version KGL_10-20-2016_1.92a_4_dmcu.img but I can't get the Head to find the .img file
I tried the SD card in the slot, GPS slot and a USB cable. Still System Update cannot find the .img file. Frustrated I gave up.
I did find that the SYGIC maps works good with the unit. I didn't like the IGO that came with it and wiped the map SD.
I also loaded Car Launcher v2.4.074 which is more appealing.
The backup camera is kind of squirrelly, works when it wants to.
Thinking about getting a new head unit with a flat screen, no buttons and knobs, but not sure if I want to go with a name brand or pure android version.
Will try to insert an image of my unit but I am new at this. The image wants me to put in a http url

@Pavel-71
thanks for the replay,
my unit says in factory settings i have a WQ_BC6 bluetooth device, is this compatible?
There should be no problem with WQ_BC6. Before upgrading to android 10, I recommend updating the MCU. Save your settings before updating your MCU. In the factory setting, there is an export button for this. Locate the dmcu.cfg file and copy it to external storage. In case of problems with the control or the image after updating the MCU, you will return the settings with it.
The update is the same as the MCU update, just use dmcu.cfg.
You can download the latest updates, including your current one, here:
MTCE_HT.rar

II do not bear any responsibility for any errors caused by the update. You do everything at your own risk !!!

Hi. I bought a Chinese FYT head unit that look exactly like Joying...
Was wondering if it's possible to upgrade it's MCU to a Joying one.
I tried downloading Joying firmware however when I plugged into my head unit... It doesn't work like Joying where it automatically update the firmware.
The zip file from Joying consist of a big zip file.. after extracting, there are some folders together with another big zip file.
I went to settings, factory, and selected MCU Upgrade .. but it doesn't recognize any of the files within.
If possible I hope this community could teach me how to upgrade my MCU....
Thanks in advance.
My unit information can be found in the attachment. PS. Not sure why XDA don't let me attach image.

short answer, no. Note, MCU is not android.
You have latest mcu (53) = YIN. what is it you actually want or think the joying firmware will provide?
Suggest reading forums.

Hi, so my issue is that the UI that it provided is not to my liking... i would want to change the UI but the seller told me that he have no idea how to do it. my friends model... same but 10 inch.... has the option in changing the UI.
In my Factory setting page... the only available UI is UI17. I was looking at other threads and was wondering if TS10 firmware works for my device. The UI that TS10 provides looks nicer.
Sorry... but i dont really understand much despite reading. IMO its just a hardware trying to flash with different firmware... and base on the similarity of the device... i fail to understand the complexity in it.... (Im probably wrong in this aspect)
P.S. Im totally new to this and is trying to digest....
I'm not sure if your firmware will allow it, but there are other launchers that can be installed from the Google Play Store. They will change the interface and many of them have different themes that you can switch to. You can view them directly on your head unit from the Play store. Here are a few:
CarWebGuru Car Launcher - Apps on Google Play
Car launcher with themes, widgets, music control, gps tracker, and customization
play.google.com
Car Launcher - Apps on Google Play
Launcher for use in the car
play.google.com
AGAMA Car Launcher - Apps on Google Play
Home screen for car multimedia systems for Android OS (30 day TRIAL)
play.google.com
After installing one or more of them, they may ask you to switch the default launcher when you run them. You don't have to. You can try them and if you don't like them, delete them. I believe if you go "home", if will go back to your original launcher if you didn't switch the default. When you go into the settings, under Apps, one of the options is to display and define the default applications for different functions. You can also change them there. I use CarWebGuru and it looks very different from my original launcher.
If anything goes wrong, as a last resort, you can always switch back to your original firmware.
Just out of curiosity, go to Google Play and look for "Fake Device Tester" and check if that is really an Android 10. I have an unbranded FYT in my car (vertical Tesla-style) and it's a fake.

You first should have read the documentation on this forum, including how to make a flashable backup of your unknown FYT unit before flashing it with something else.
And what did you do? Flashing the firmware or trying to upgrade your MCU with a Joying MCU (rule no. 1: Never ever do that !!!, and this is also rule no. 2 to 15)
Your flashed Joying firmware probably has in its config.txt the following line
Code:
sys.fyt.bluetooth_type=1
I guess your unit needs either 0 or 2.
The radio not working is probably due to a mcu firmware mismatch. Joying is type 43 (ro.build.fytmanufacturer=43). Your unit is probably 0 or 116, or some other value. Do you still have your orignal firmware with the original fyt.prop?
