Hi yes. Only flash through recovery.

I have solved the issue. Depending on the ROM you install, it will lock down the type of MCU you can install.

I changed the ROM to a GS version and then it let me install the MCU for my GS model.

Therefore if you install the HA ROM... it will only let you install HA MCU's in recovery.

It would be great to find where the MCU identifier is in the ROM as i want to install Malask's ROM but still be able to update the MCU in the future.

Lastly - updating the MCU did not fix the bluetooth not working but i guessed that would be the case since the bluetooth & wifi chip is soldered onto a USB header (therefore its just a USB device and has nothing to do with the MCU)

I will try this with my unit, maybe it works.

Thanks for the tip.

Ok, the resolution from sreen is now ok. But I only have updated Android. I still have mcu HA, not MLT. The radio don't work, so the next is update to MLT mcu, if its works.

The strange is that resolution works with android update, and not with mcu update.

Let's what happend next.

---------- Post added at 11:41 PM ---------- Previous post was at 11:32 PM ----------

The radio is working, but in wrong mhz. I live is Spain, and we don't use 65-74Mhz. But it works..... I don't know if the full frequenzy. With mcu HA firmware. The last test is with MLT mcu firmware.
[MTCD Android Head Units General] marchnz:
Have you tried selecting correct country/frequency range in factory settings?
[MTCD Android Head Units General] typos1:
Read the thread to find out how to change the screen resolution.

If anything, an RK3368/PX5 SoM will give you even more problems if used with an old MCU.

Interesting, I had assumed when recovery wouldnt let you install a different MCU it was down to the Android version rather than the ROM.

I have attached the latest MLT MCU that I have, cant remember what version it is, but pretty sure its later than 1.61.

It doesnt work, I spoke about this with you a few weeks back.

I have a xtrons mtce gs unit. the bluetooth calling is horrible and not usable. I updated to the latest gs mcu i could find but didn't fix my bluetooth issue. I even bought a comfast wu725b as was told it would work however my unit wouldn't recognize it. I've seen on the forum that you can switch to a different mcu but just an confused as which one I can go to. My current mcu us mtce_gs_2.78.
[MTCD Android Head Units General] marchnz:
MCU isn't going to solve BT quality issues. You don't mention what the issues are? Call quality from my experience is enhanced by connecting a quality external mic and disconnecting internal, but you mention screeching noise, which could be feedback or simply a defective head unit.

There are multiple threads on this issue, suggest taking some time to review these forums.

Hello,

is it possible to upgrade my MCU : VX : 12/12/25 device to some other version?

thanks!
[MTCD Android Head Units General] typos1:
Read the thread, if no one else has done it then maybe, you ll just have to try and see.

thanks for response.

im really layman so I asked, because I have to know if there is some way to upgrade this device. Could you help me with recognise what the operation system is?

Hi,

I have the same issue with my KGL unit.

Did you try a other MCU for your unit ?

Best regards
[MTCD Android Head Units General] sliderx89:
Hi EagleSoldier

Not yet, I've read that thread but did not get the answer which MCU repair the issue. Soon maybe I will try with HA MCU, confirmed as the CC but for now I have child in hospital so car is not the priority.

If You will try first please write here, that problem is resolved.
[MTCD Android Head Units General] EagleSoldier:
KGL -> HA works perfect

Hi,

nvm, Ive tryed it out myself.

I installed the newest HA MCU on my KGL device, restored the mcu.cnf and everything is working.

I will report back here, when I find a issue or something like that.

Has anyone problems with the MTCE MCU?

I have two GS units which get stuck about every two days because of the MTCE MCU. On both is installed the original ROM and one unit is about a week old and there was totally no modification done. With the MTCD MCU the one which I already have since November gets stuck about every month once.
[MTCD Android Head Units General] makes2068@gmail.com:
Got an Erisin 3015 with upgrade board from witson Android 6.0.

Original mcu was LM. After installing upgrade board, flashed often other mcus and all are working.

Since a few month (maybe after an update of malaysk) only GKL mcus are working. No others, also not the oroginal LM.

"Version unmatch" error all the time.

There are no cfg-files on sd card or stick. Maybe elsewhere?

Any hint? Wanna try other mcu because of no autosleep ;-(
[MTCD Android Head Units General] maus05:
Does anyone have a new

Mtce kgl mcu?

I am running on 2.70_2 and for other resellers you can get 2.8x.

I have some problems with mp3 listening because sometimes the sound clips.

I don't know if it's related to the mcu or the Android 6.0.1.
[MTCD Android Head Units General] stefcio007:
I updated my MTCD_KGL_V2.54_5 to MTCE_KGL_V2.70_5.

No issues but didn't see any improvements, maybe bluetooth audio (A2DP) is less crackly but that could be due to the better antenna I installed and I didn't notice it before. Audio via music player from USB/SD or CarPlay is fine.
[MTCD Android Head Units General] typos1:
You have to make the .cfg file yourself by pressing "export" in factory settings, you should have done this before trying an MCU from a different manufacturer.

Look in the MCU thread.
[MTCD Android Head Units General] makes2068:
Tried without success.

Cfg file stored from working mcu.

Than installed other mcu together with the cfg file.

Gesendet von meinem Xperia Z3 mit Tapatalk
[MTCD Android Head Units General] typos1:
You need to make the cfg file BEFORE you ever change the MCU, it wont work AFTER youve changed it.
[MTCD Android Head Units General] makes2068:
O. K.

But that is no longer possible so...

Found one...

What to do?

Flash the original cfg file together with new mcu? Can't imagine that this could solve the problem.

Gesendet von meinem Xperia Z3 mit Tapatalk
[MTCD Android Head Units General] makes2068:
Nothing works.

Stock mcu with cfg file = version unmatch

New LM mcu with old cfg file = version unmatch

Old mcu without cfg file = version unmatch

New mcu and all other mcus than KGL = version unmatch

I think the combi erisin 3015 with build in can bus, together with new witson Board got this problems.

[MTCD Android Head Units General] EagleSoldier:
Had the same issue...

Flash one by one

First new MCU, then reboot (it show unmatch).

After that delete the new MCU on your SD Card and press again install MCU.

The Unit detect the .cfg file as a normal MCU and it will install.
[MTCD Android Head Units General] makes2068:
Which cfg-file? The original one or the saved one from the actual mcu that works?

Original mcu was LM

At the moment unit only runs with kgl mcu
[MTCD Android Head Units General] typos1:
Theres no such thing as a "Witson board" ALL MTCB/C/D/E boards are made by HCT.

Yep, thats the only way to do it, he can try MM if its an octacore unit.

Only way to sort it.

[MTCD Android Head Units General] makes2068:
Installed LM 2.81 together with LM 1.90 original cfg-file without success.

[MTCD Android Head Units General] Electrified Bill:
Greetings. I have an odd one: MTCD_HH_V2.42_1 was the original mcu. I read somewhere that HA is compatible with HH, so I flashed HA and now have unmatch error with an annoying ping every 5 seconds. I have tried just about every mcu I can find, with no luck. Does anyone have an HH mcu, or a workaround to stop the pinging? The unit is an LMY49F running Marshmallow, originally Lollipop.

I have successfully upgraded to MTCE_KLD_V2.78 from MTCE_WWW_V2.80_1.

I used the config file back up as well and had no issues.

This fixed the issue I was experiencing with my wifi failing to wake up after entering sleep.

I upgraded to KLD_2.80 first and had the same wifi problem. This adds more ammo to the argument that WWW is exactly the same as KLD with the exception of the power button on WWW muting the device with a short press and powering off with a long press. On KLD a short press powers the device off.

I have the MTCE_WWW_V2.80_1. on an EONON GA9180a, are there any updates? shows last kernel was March 2018
[MTCD Android Head Units General] Archie_Slap:
I haven't found any online. I've asked Eonon to send me an update though so I'll see if it happens.

Are you having any problems with wifi not working after the head unit goes to sleep? That's been my main reason for wanting to update.
[MTCD Android Head Units General] veriluxxxx:
my problems might be related to that, the wifi speed is great when connected at first between 10 to 30 mbps then after a couple of minutes it slows down to .2 to .3 mbps. I tried changing the wifi always on in the sleep settings but its still having the same issue
[MTCD Android Head Units General] Archie_Slap:
Does pressing the reset button fix the issue? It would for me until the head unit went to sleep again.

I changed to KLD_V2.73 and it fixed it for me.

I also went into battery optimisation and turned everything in there to not optimised, not sure if this helped.

Eonon have sent me WWW_2.85 which I'm trying at the moment. If it doesn't fix it I might send it back under warranty and see if it could be a bad wifi chip and not software.

I've got the GA2170 and it works great apart from this.

GS 2.43 to HA 2.52

Just wanted to add my experience aswell - I had the same when updating the MCU on Xtrons to the HA 2.52 with the mismatch error showing up all the time.

I could run another MCU upgrade with the dmcu.cfg file I exported before the upgrade, and then it would take the settings - but every time the unit lost power, (I was testing it on the bench, so had it disconnected completely a few times) it would then load back up with the default settings for HA 2.52 and then show the mismatch error again, until I re-flashed the cfg file again.

I also rolled back to GS 2.43 and again back to normal.

I'm tempted to try the new 2.56, but I'm guessing the result will be the same...

Thanks to the original posters and everyone who's working on these units! When I was researching which one to go with for my new nav system, finding the number of threads on these PX5 units with discussion, tweaks, mods etc was a BIG reason why I went with one!!

Hi,

I would like to share what happened to me. 2 days ago I upgrade KD 2.41 to HA_2.65. Few hours of testing and system work's fast and smoothly. I was verry happy ... by almost one day. All magic happiness was gone next day when suddenly my unit go in blanked mode. Ignition off/on, hard reset it did not give a result and unit won't start up. Lucky for me I can enterable to recovery mode and reboot. After that desktop of my unit was blinking few times, radio, music, navi didn't respond. I do not have many time to testing that day and wait for last day. Today my multimedia system all was dark (black screen, no power on led). Again lucky for me recovery mode and downgrade MCU to KD 2.41. I finish 2h ago: all needed aps work's great like before I starting upgrade MCU to highest version. Now I was finish 20km route test on my city with active unit. System works for now. I don't know what happend. Maybe MCU HA 2.65 is not compatible for 100% for KD mcu unit?
