[MTCD Android Head Units General] marchnz:
Welcome to the quirks and poor QA of these headunits.

Help us to understand by listing 'many problems' as you appear to have a new MCU and Android version, which you seem to assume to be a software/firmware issue.
[MTCD Android Head Units General] ikerg:
First which unit do you have?

You could try to use other brand mcu update that will be similar than yours.

Overall if you have a specific car model unit.

I think this is directed at the posted I responded to.

Also, if I dont know what you mean by 'other brand mcu that will be similar to yours', not sure anyone else will. As my understanding is that MCU updates are not always cross compatible, have a cross reference to share?

Unfortunately the B/T and Wifi did not work and the vendor's response was that the MCU installation was wrong and this machine is MTCD GS and download the following new files and upgrade ...:confused:

[MTCD Android Head Units General] marchnz:
Confirmed JY and KD MTCD are identical.

Given MTCD_KD_V2.06_1 and JY v2.06 are the same, I successfully upgraded my JY with KD_V2.40_1.

So, confirming KD MTCD firmware applies to JY / Joying.

Note - Before upgrading suggest a config extract (factory settings) as upgrade resets all factory settings. Also note brand becomes - "a-media" which too is configurable from factory/MCU settings.

is KLD interchangable to KD?

If not what is the latest KLD MCU release?

thanks!
[MTCD Android Head Units General] marchnz:
Thats actually great news! You've confirmed that GS updates will apply and confirms my hypothesis that the MTCD MCUs are cross-compatible - atleast for JY,KD and GS. I have confirmed that JY&KD are compatible and today working on comparing GS MCU Code (using a compare tool) and found your helpful post.

Note. Restoring the volume control while keeping GS is achieved by going into FACTORY SETTINGS and setting KNOB in [Other].

You can BACKUP these MCU settings by using the export item. This generates a MCU config, which you can apply to restore your settings - the file is copied to the GPS card. To apply it, make sure no other MCU update files are on the root of the GPS card, then go to 'Update MCU". It will then apply the MCU config. This can also be applied when updating the MCU by including *both* files and running the update.

So we now have: MTCD JY, KD, GS &HA MCU confirmed cross-compatible. HA v2.52 is the one you want to enable shutdown control on PX5.
[MTCD Android Head Units General] marchnz:
After going into [Factory Settings] and testing various combinations of Bluetooth settings, bluetooth and WIFI still does not work, you likely have a hardware issue.

Note that [Factory Settings] controls the MCU settings.
[MTCD Android Head Units General] marchnz:
I can now confirm HA is compatible after applying to my JY MCU.

So, JY, KD, GS and now HA are cross-compatible. I initially upgraded to KD 2.40, then HA v2.52 after first exporting the MCU settings.

This is very useful for those upgrading their MTCD px3 to PX5 as MCU HA v2.52 enables the settings menu "shutdown delay when ACC off" to choose between sleep or a period upto 2hrs.

Note that I had to reapply MCU settings in [factory sertings] to configure radio, LED, bluetooth, hardware keys etc.
[MTCD Android Head Units General] nadkp:
Hello marchnz,

you wrote GD, but is it possible that you meant GS (xtrons)?

I ask because i have a xtrons device and there are no updates since the beginning of may i guess. No update with the possibility to change the "shutdown delay"
[MTCD Android Head Units General] marchnz:
Whoops - GS, not GD! Be sure to extract your MCU setting or documenting what they were set to.
[MTCD Android Head Units General] Lisu87:

https://xdaforums.com/showpost.php?p=72725640&postcount=1294
[MTCD Android Head Units General] marchnz:
Hi,

I have found they probably are. First compare your MCU file against another vendor MCU file. If same, they are cross compatible.

Note I have MCUs for MTCD HA, GS, KD & JY confirmed cross-compatible.
[MTCD Android Head Units General] Lisu87:
Then if you feel confident enough try to flash something else and let us know.

If not, for sake of other less experienced user better say it is not compatible.
[MTCD Android Head Units General] marchnz:
Hi, Yes, indeed I have flashed v2.52 on my JY. The user could also check the part number of his MCU -If it is STM32F091 it is compatible. As always, have your original MCU and either extract the factory settings or document factory settings before upgrading. I have compared KD to HA - it too appears to be compatible, and you're right, this needs to be tested.

Yes, flashing is risky.
[MTCD Android Head Units General] Lisu87:
Thats nice, but I'm interested specifically about KLD. Did You try to flash?

You're welcome. Yes, a hex editor. They are encrypted by what looks to be an additive cipher which results in a constant 'pattern' that has permitted a basic comparison.

[MENTION=264470]Dark Simpson[/MENTION] had created a tool to decode the earlier MCU images - however it doesnt decode MTCD MCUs - I tried by compiling his version 1.1.

https://github.com/darksimpson/mtcmcutool

If we had someone skilled here, suggest a decipher might be achieved by reviewing the android code/recovery as thinking must first decipher before applying to MCU. Any takers?

If we have a full decode, we could begin to reverse engineer the MCU and potentially make many improvements.

Hello,

I`m about to update my mcu with the suitable dmcu.img. First I wanted to export the factory settings.

I find 3 buttons in my factory settings menu: "Apply" , "Export" and "Exit" but no button to import saved settings.

After updating how do I reaply these settings?

Thanks!
[MTCD Android Head Units General] nadkp:
The export file will be saved as dmcu.cfg. After updating the mcu, delete the mcu.img and do another "update". This time the cfg will be imported.

Some other users said, that the import of the config file will be done with the update at the same time, when both files are on the same sd card in the same directory, but in my case that did'nt work. i had to delete the mcu.img.

Good evening, quick questions, I`ve bought the PX5 coreboard, from WITSON, for my RK3188 MTcD GS v_1.52_1 with px3

2. Can I jump from MTcD_GS_1.52_1 directly to GS_2.43 ?

3. I`ve found the GS_2.43 here, on this thread, how do i know if it is MTcD or MTcB or MTcC ??

Wheel Key Hardware Fault

Hi All, after a few failed upgrades, I was able to restore my brand new HU through my PC. However, I fear that the hardware of the wheel key in my HU is bricked or faulty (I have tried with many MCUs firmwares but none of them solves the problem because the wheelkey does not react any longer). My question is: do you know whether the hardware of the wheel key is embedded in the SOM module or on on the motherboard? If it is embedded on the SOM, a new SOM would solve the problem.

Thank you in advance for your replies
[MTCD Android Head Units General] B3rt:
don't believe it is in the SOM.

I replaced my SOM with an upgrade to PX5 and had no changes to make etc at all.

I did not specify which car brand etc i am using, got an other SOM , replaced it and worked immidiatly.

So i believe your keys are stored/controlled on the main board, not in the SOM (android system) of the unit.

AN other question, how did you restore the unit using a PC?

I myself have also a bricked (mtcb) unit lying around and have no idea how to get this working again.

I accentially flashed this mtcb unit with mtcd rom, after the boot the android part went black/dead and that was it.

Unit is not responding anymore, nothing works, it even does not boot up.

I bought a new unit (now mtcd) but i want to try if i get this mtcb unit working again, so detailed instructions how are appreciated.
[MTCD Android Head Units General] hermes-1969:
thank you for the detailed reply. However, how can it be that the HU is not responding any longer to the steering wheel remote control? Anyway, after many tries, I was able to restore the HU with the rockchip flash tool via PC ONLY after connecting the two USB ports to two different USB ports on the PC. This was the only way to have the HU recognized by the PC so as to be able to flash it without needing to access the recovery interface on the HU. Anyway, would you be interested in selling your PX3 SOM, if you do not need it any longer? Best.

---------- Post added at 01:23 PM ---------- Previous post was at 01:13 PM ----------

I am claryfing my last reply. .....do you think that by wiring correctly an external CANBUS through the HU and the car harness I might solve this issue? In this way, I should be able to bypass the hardware canbus of the HU and make it work through an external canbus. What do you think about this solution?

Sorry to hear it hasnt worked out for you. I recall having to enable RDS in factory settings to re-enable it after MCU upgrade to HA.
