This is the first post I have seen for a MTCE.WWW update. I have a Eonon GA2171S with MTCE.WWW.V2.85d_1. I would assume this would be compatible with mine too since MTCE.WWW after reading thru many pages. Would that be correct?

Are these units so new that not many people have them?

Thank you,

Todd
[MTCD Android Head Units General] Archie_Slap:
As far as I know it definitely should be. I flashed a whole bunch of different WWW versions of MCU firmware trying to fix a problem my unit had and I never had any problems with compatibility.

I've tried different KLD versions as well.
[MTCD Android Head Units General] TH513:
When you updated using the MTCE.WWW, did you need to backup your config and include with the update in the root usb/microsd?
[MTCD Android Head Units General] Archie_Slap:
I backed mine up and copied it with the upgrade just incase.
[MTCD Android Head Units General] TH513:
Thank you. Will do mine too!
[MTCD Android Head Units General] TH513:
Sorry I did not answer your wifi question. I have not had any issues I have noticed. It seems to work well. I did upgrade my mcu and was easier than thought it would be. I just had to figure out password for my unit which I found in another forum

Thank you for answering all my questions!

[MTCD Android Head Units General] Archie_Slap:
I have just installed an Eonon GA2175 and have a pretty bad crackle and pop when playing music from any app except the stock radio app.

I think this could be an issue with the digital to analogue converter as the radio would be an analogue signal and the other apps all digital, but I'm not sure how this works in these units.

Does the MCU have any involvement with the audio signal or is it just related to the hardware buttons etc?

I'm wondering if trying different MCU versions could fix this problem

haha, lol, didnt even notice this feature. Thx, dude.
[MTCD Android Head Units General] zerozoneice:
i do have a problem with MCU files that apparently the vendors themselves (like GS Xtrons) are not aware of, but somehow appear on yandex drives...

can anyone therefore verify the source of GS MCU v3.07? According to official Xtrons support, latest they have is v3.01_03. Funny enough, the HU serial# was empty after upgrading to v3.07....this didn't happen when i upgraded using official Xtrons MCU (received from their support) from MTCE_GS_V2.90c_3 to v3.01_03

something doesn't add up....

by the way, going from v3.01_03 to v3.07 seems to have made my FM reception worse for particular "fringe" stations. Old MCU had no static, whereas v3.07 does introduce static once in a while. Can MCUs be downgraded?
[MTCD Android Head Units General] bovcan:
I belive you can downgare it.
[MTCD Android Head Units General] zerozoneice:
i did, went back to GS v3.01_03 as supplied by my vendor. Guess what, the static in the same FM station disappeared.

i emailed them about this GS MCU v3.07_03 running in the wild (on yandex) and they said they don't have it out as official build, could be a testing version but they don't recommend installing from other sources than official support.

since i haven't EVER seen a changelog of any MCU version out there, i'd take those "new" releases with a huge grain of salt....just my 2 cents. Especially since versions appear now that are "hacked" to support the cs_x soundmod, who knows what else's being put on there...

are u guys completely confortable installing stuff on a device that has access to your google services account, maybe even creditcard details on playstore, let alone whole list of contacts & others? how many of you do actually have a dedicated dummy google account just for the headunit in your car? :)

all respect to devs & community, but until i see changelogs/sources being x-checked by the community, i'll skip on "custom" MCUs. thanks but no thanks. Maybe i'm wrong and/or over-paranoid, but can anyone please prove me wrong and post this info?
[MTCD Android Head Units General] donny02:
Just tried to change mcu from hxd to ha, because I was not happy with "Shutdown delay when ACC OFF".

I managed to flash ha mcu, but after that the display was mirror-inverted from left to right. After some tries I managed to restore the saved mcu configuration and then this problem was gone and everything looked quite good. But after power off the settings were gone again and display was mirror-inverted again.

Shutdown delay did not change with ha mcu so I decided to flash hxd mcu again. After this everything was good again.

So at least I can assure that you can flash another mcu with no high risk if you have the original mcu to go back.
[MTCD Android Head Units General] bovcan:
How to import dmcu.cfg?

first go to factroy settings (pass 126, or similar) and click export. Save the file to SD, usb whatever.

on that usb copy dmcu.img file as well.

Now go to About system, click update MCU and wait till it reboots. After you are back in go to File manager, that USB, delete dmcu.img and go BACK

to About System and click update MCU again. Now it will apply dmcu.cfg file.

REboot and you are on.

hello, i'm wonder, if i can try a HA mcu, mine is a KLD 2.88, i know i can use the app called "unmatched unlock" to force the MCU , but can i go back to my factory one after that ?
[MTCD Android Head Units General] LoCk3d:
Hello guys!

I also made the mistake of installing another MCU version .... I had the version MTCE_XRCE2_V2.84_1 (May 2 2018) and now I installed the version MTCE_HA_3.14 (last version from thread https://xdaforums.com/android-auto/...asaita-mcu-updates-rockchip-px5-octa-t3575155).

I had the error "Version Unmatch -01" and I solved it with MCU Unmatch Unlock (from thread https://xdaforums.com/android-auto/.../solution-version-unmatch-hope-final-t3805092) but the touch buttons still do not work...

Can anyone help me with the version MTCE_XRCE2_V24_1 or a newer version for XRCE ?

Any other advice to solve this problem?

Thank you!

EDIT: I finally found version 3.01. After that I also updated Android 9. The touch buttons works now but the light from buttons not work... any advice ? I search through settings but nothing :(
[MTCD Android Head Units General] marchnz:
These issues are all covered in the first post, are you sure you have followed the steps and fixes in the first post?
[MTCD Android Head Units General] LoCk3d:
Yes, when I had Android 8 I was able to get into the manual settings, I reset the buttons, so I made them work again. But after update Android 9, I can not get into the manual settings anymore. There are many ways to get into manual settings?

All work well (even if it looks like android 9 is moving a bit slower than android 8), just the fact that it does not light the touch buttons anymore.

Mtce_gs_v2.72_3

Sorry if it is not on the right place...

Does anyone know how can i gat the exact same MCU?

Because i flashed dmcu(MTCE-GS-2.94sp_by_cs-x) on an X-trons ANDROID 7.1.2 | PA77BYFP with MCU: MTCE_GS_V2.72_3

After the upgrade the touch screen is inaccurate most annoying at it's left part, there it senses almost 1cm difference. Loudness is not working at all.

so i'd love to install the old MCU back on it. MTCE_GS_V2.72_3 but can't find anywhere.

by the way is there anywhere a stock Android 7.1.2 (rooted if possible) because Malaysk rom is also way too slow, and buggy. Google maps exits, musicplayback suddenly stops..

so it is not my best choice for sure.

Hi i got newer firmware from xtrons support, but not exactly same version, left 1cm of touch screen still not working even after flashing new MCU and Android all other function is ok. They suggested me to buy new display for 50 usd :/
[MTCD Android Head Units General] thienthanty:
You have to return the old one or not?

I have alot time because Coronavirus, so now i can fix 90%, only bluetooth not work. Hope today all thing back :)

Thanks !
[MTCD Android Head Units General] themissionimpossible:
You might have to recalibrate the touch screen accessing the Factory settings.

This happened to me in the past (on another brand head unit).

Before upgrading the MCU one should export his current MCU config in Factory settings, and import these settings in the head unit after the MCU upgrade.
[MTCD Android Head Units General] thienthanty:
it's easy if dont change the resolution. My wife unit is Xtrons PX5 800 x 480, the resolution change to 1024 x 600, too hard to recalibrate the touch screen. i have to flash the dcmu.img & dcmu.ext with the screen:1 to back 800 x 480, then recalibrate the touch screen....
[MTCD Android Head Units General] Imre_Orsos:
No thscreen is not covered by the warranty but they can send new screen with faceplate for 55 usd. By the way i did not ordered it, because i still think it has to be something with the config on it. I did not have the time to check it yet. Regarding BlueTooth, may you try different bt devices listed in factory settings, i made it work on mine. But the screen it has still 1cm on the left side which is not sensing touch. It is a bit annoying, because on the display i can't press 1 doue to its position. If you could solve it i would be grateful if you share the solution. I tried to recalibrate it, it doesn't sense there.

---------- Post added at 06:57 AM ---------- Previous post was at 06:54 AM ----------

I tried to recalibrate it there, but it is not sensing touch on that part even when doing so. :(
[MTCD Android Head Units General] thienthanty:
Yeah i fixed the bluetooth by change to SD_BC6 :D. If you have same the resolution like my HU ( 800 x 480 ), you can put together the MCU file ( dmcu.img ) & the file i uploaded here ( dmcu.ext ) to your usb or sdcard, then flash the MCU. Now the screen come back to 800 x 480, then you can tried to recalibrate it. Hope all back :D

Dont flash my PX5 rom if you have your stock, jsut fash the dmcu. ext & your mcu.img

Thanks, i just updated MCU and mcu.ext but it din't help, by the way i can be sure my display is 1024*600 :D because 800*480 was too small on screen with black lines, so i changed the screen back to screen:3

touch is still not working the 1cm on the left :((
[MTCD Android Head Units General] thienthanty:
Try to change the screen to screen:4 :D

[MTCD Android Head Units General] bilaliz:
I read quite a bit of this thread but I don't understand one thing, are the MCU versions cross-compatible over the type of chip you have? i.e. I can apply a MCU version from a PX5 over to an RK3188?

There is no such thing as a"PX5 MCU version" or an "RK3188 MCU version" - the MCU and SoM are TOTALLY separate.

Is there any MCU that has the "Shut down delay after ACC off" option of more than 2 hours?
[MTCD Android Head Units General] MediaTerraneo:
Hi, what I should try is flashing again blindly. I managed to do it in the past.

So try to:

1. Find the right dmcu.ext

2. Find the way that can run the recovery mode, even whitout the screen help (you can try counting secs and observing the way the led flash)

3. The recovery menu has standard rows and you can move with the buttons and hearing the beeps. In the menu you have:

- Reboot system now

- Apply update system

- Apply update mcu

...

If I'm not wrong you should:

- short press twice to move from Reboot to Apply update mcu

- long press to run unpdate mcu

Please find a way to be sure on steps above, because the 4th menu row is "Wipe".
[MTCD Android Head Units General] freaksamael:
Well, all good now. Flashed blindly and succeeded by chance :). Thank you!

But now another one...H\W keys are lost; talking about this unit : https://www.aliexpress.com/item/32792230949.html?spm=a2g0s.9042311.0.0.355d4c4dhihRhg

Tried somethings in factory car settings, no luck :(. I can use the HU without, but it will be nice to have them back.

Anyhow, I can use now the HU. Thank you for support!
[MTCD Android Head Units General] MediaTerraneo:
You welcome!

Who is the manufacturer? You know that MCUs have an abbreviation inside that refers to the specific manufacturer, such as GS, XRC, ... Are you sure you have flashed the correct one for your radio?

You already said you looked in the factrory menu. Have you also tried changing the version (Version 1, Version 2, ...) in that menu?

Finally, I suggest you contact your seller and require him for an update of the MCU: you will get a dmcu.img that you will have to flash. That will probably restore the functioning of the HW buttons.

Cheers

Some questions

Hello friends, I have been reading the whole post and there are some questions that are not clear for me, they are:

Why upgrade to HA and not to other manufacturers? (most of them, here, do it like this) maybe Daisata (HA) has the best advances and corrections in his MCU?

I also imagine that the key to enter in factory setting. Does our original key change or reconfigure when we send it the config .cfg file?

I imagine that the screen will also have to be recalibrated?

I could only tell you that I have KSP.

Hi guys. I have xtrons tq700l player. I did changed my mcu (mtce gs) to HA version, and i didnt know what i did in between, the version mismatch error was gone. I couldnt use the apl because the app kept on crashing on android 10. Now, for whatever reason the mismatch error appears again, and i did ask for the original gs mcu from xtrons. They gave me ota update and mcu files, however after flashing them, the mismatch error is still there. Do i need to wipe data and flash to correct this?
[MTCD Android Head Units General] marchnz:
No, you need to do a search for "version unmatch".
[MTCD Android Head Units General] shahru98:
Hi! Thanks for the heads up. Unfortunately im not able to decode the dmcu.img file using mtcdmcutools. It gave away “error reading file” when i tried to get the .bin file from the .img file. Im using the dmcu.img given by xtrons. Any idea?
[MTCD Android Head Units General] marchnz:
Cross post of version unmatch thread. That's the right place to ask.
[MTCD Android Head Units General] shahru98:
I have a question. The version unmatched error went away when i reflashed the MTCE HA mcu, but came back as soon as i restore my cfg.

Any idea why so? Using factory given MTCE GS file will bring the version unmatched error. Im confuse with this because GS is the one that the player came with.

Now with HA file, i lost panel touch (unable to configure it too) and the illumination when turning on headlights keeps on blinkings. Im fine with this its just i need the panel touch ability. Any idea on how to get it back?

Should I try another mcu files, maybe JY? MX?

MTCE-HZC-2.94bp+by+cs-x and MTCE_HZC_V2.74,

unfortunately I did not find a newer version.

it safe to try to install the version of HA,

at worst go roll back to the versions I mentioned above.

Go into factory settings and export them to get your config before you do anything.
