I had similar problems but finally my unit was not to be used.

One more: after downgrade to KD 2.41 I lost audio in front, left door of my car when I configured my unit.

It was accidental, after another restarting unit works ok.

I think it will be better to reflash mod rom again with clear/wipe options.
[MTCD Android Head Units General] ale_kons:
Any instructions on how to do this? I have messed up the buttons and the MCU update didn't fix the issue.

Talking about a GS unit
[MTCD Android Head Units General] typos1:
You have to do it before you mess with anything, if you do it now your mcu.cfg will be with your messed up buttons.

In factory settings you can assign buttons which should sort your problem.

Cant believe this thread. I'm looking and reading through tons of xda threads and posts to find answers to my problem. Wasted literally hours.

It quite clearly says in 1st post not to dilute, but even what started with a simple list and clear info there are 60 pages of lazy ignorant posts.

Makes me so mad. I pity the OP and similar contributors.
[MTCD Android Head Units General] typos1:
Lol, love the irony of your post - youre complaining about "dilution", yet youre diluting the thread yourself with that post.

Whether "diluted" or not, you often need to read the whole thread on xda, or anywhere, to find what you want, this takes time, sure it can be frustrating, but thats the way it is.

This thread is mostly undiluted and very helpful, your suggestion that "there are 60 pages of lazy ignorant posts" suggests that every post of every page is "lazy" and "ignorant", which is rubbish and likely to really p*** people off, meaning it less likely that you ll get any help with your problem.

Not that the few people who would try and help you after youve insulted them, could help you, even if they ignored the insults and wanted to - you havent told anyone what it actually is !

What was it you were saying about dilution ? !

Can't flash MCU

hello all,

I changed my MCU and the screen resolution was all messed up after flashing through recovery.

I attempted to flash my old MCU in recovery using the same process but the unit just hangs and then resets when I try to update to my old or any other MCU.

Can someone please help or is this now broken?

Thank you in advance!!
[MTCD Android Head Units General] typos1:
Did you try flashing your mcu.cfg ?
[MTCD Android Head Units General] jnlil83:
In my haste I didn't get the config. (I know I should have).

When I try to load the dmcu.ext it just pulled it up then restarts and loads the wrong screen resolution

Hi Guys

I have a Isudar unit MTCE_GS MX5. 32GB v.8.0 Android. I just had a new main chip installed as the system would not power on (from re-seller). However, now i have no sound.

Seller gave me two new MCU's to try, MTCE_GS_V2.89b and MTCE_GS_V2.88. Neither are good it seems, as my 1024 x 600 screen is showing a smaller image than my screen size, and still no sound, i can hear the beeps from the buttons, but no audio.

2.88 just had an img file and nothing else, 2.89b has a .img file and a dmcu.ext file. am i correct in saying the image file installed first then delete that from teh SD card and run install again with the .ext file?

Or is there a better version available at all as the re-seller has been messing me about since May 2018... and i think i have used my unit a total of 3 weeks. I bought this as the Mercedes C class specific one (perhaps that does not matter other than the fit to the car?)

I am a little bit of a noob so please be gentle with me :) but i can install the MCU images :) yay!
[MTCD Android Head Units General] Kwaka_man:
Just to add, this is the unit i bought... and what the screen looks like after the MCU updates i received, also if i open the file dmcu.ext in notepad all i can see there is "screen:0" and nothing else.

The thread tells you how to change the screen res, pretty sure its the ext file.
[MTCD Android Head Units General] Kwaka_man:
Do you happen to know what setting should be for 1024 x 600 resolution? Or is this just lucky, trial and error? Does the file have to edited and then be uploaded new each time? Or can you just edit the file on the system and re-boot the unit?

Many thanks before hand

p.s. Edit: yes i believe i saw that thread as well :)

Very sad.

I bought the pumpkin 8.0.0 double din.

First issue, the MCU version is CSN2_1122018_153527.

It's defiantly does not start with MTCD/MTCE.

Anyway, I tried to install Hal9k 8.0.0 on it but it stay stuck on "Android Starting" after "modinstaller.apk" reboot.

If I power cycle, I get back to my stock firmware. At least it's not bricked.

Any suggestion?
[MTCD Android Head Units General] typos1:
So youre saying even though you knew it wasnt MTCD/E, you went ahead and tried to flash an MTCD/E ROM on it anyway ?!!!

Look in the Android Headunit general forum for a thread about your unit, no one in the MTCD/E forums can offer any help cos its not an MTCD/E unit.
[MTCD Android Head Units General] meazz1:
That was oversight on my side, I was thinking all PX5 comes with MTCE/MTCD file.

I read this forum many times but was too excited to flash as soon as I received the headunit. I had it power up, as soon as the unit booted I started flashing.

Anyway, I returned the unit and ordered one with MTCE files, confirmed by the seller before purchasing.

Is there any advantage in cross-patching?

I'm having a problem with my Dasaita V600 WiFi working but not being accessible. Posted in thread:

'MTCD PX5 Headunits Repository & information (Stock & Custom) by ikerg' and post #619

Is it likely that an MCU patch from another manufacturer would work for me when the patch I have is HA V:2.8_1 ?
[MTCD Android Head Units General] typos1:
There are no MCU "patches" - you simply flash an MCU from another manufacturer, having verified from THOROUGHLY reading this thread in its entirety, which other manufacturer's MCUs work on HA units.

It may or may not fix your wifi problem, the only way to find out is to try, unless you can find someone in this thread whos had a similar problem and solved it by using another manufacturer's MCU, which would give you more certainty.

Personally, I d update to the very latest HA MCU modified by [MENTION=9297693]cs-x(RU)[/MENTION] from his thread, flash [MENTION=5092263]Hal9k_[/MENTION]'s ROM and see if that sorts your problem, then you can look at other solutions. Install a terminal emulator first so you can check whether you have a version 1 or version 2 MD725 BT module, as I said in the other thread, you cant use Oreo if you have version 2.

Hello,

I have an GS Device. Currently I use MTCD_GS_V2.58_1.

Did I understand correctly, that I can safely install

https://mega.nz/#F!OZ8yRZYI!-9Fgl5aV13K5x0ilujClkA?fcU2iYqS (which is for GS MTCE)

but that I need to fix the version-unmatch problem first?

As I am using the MCU of the same manufacturer: Do I need to save and reload my settings (dmcu.cfg)?

Regards,

Hendrik
[MTCD Android Head Units General] marchnz:
You can use any MTCD or MTCE GS MCU. MTCE appears to replace MTCD.

Documenting the current factory settings is a good step, however would not expect any change as you are not changing MCU manufacturer.

Version unmatch is very unlikely for the same reason.
[MTCD Android Head Units General] henfri123:
Thanks,

I tried it. It worked -no version unmatch.

But the screen was reversed in x-direction. I was able to fix that by going to Factory -> 126 and there calibrate the screen.

I then imported the dmcu.cfg.

It was hard for me to find out how to import it (as there is only an export-button). I learned in the end, that this works by creating a stick with only the dmcu.cfg and then doing a MCU-Update with that file only (instead of a dmcu.img).

Greetings,

Hendrik

Also had to set the CANBUS and BT type manually back to correct values.

have version mismatch -01 and regular beep. will try documented process to clear.

I dont know how its not clear, has anyone successfully managed to use an HA MCU on an LM unit in this thread or not ?

[MENTION=9297693]cs-x(RU)[/MENTION] has LM 2.94 in his thread.
[MTCD Android Head Units General] gwaitsi:
not clear, as in 64 pages and none that say;

1) backup existing dmcu.cfg and take copy of factory settings for reference (as dmcu.cfg doesn't get restored)

2) copy dmcu.img and dmcu.cfg and McuUnmatchUnlock.apk to root of SDCARD

3) use MCU Update from the settings about menu

4) got to settings, car navigation. factory settings (password change from 3368 to 126) and set LED type back to RGB and re-learn touch key types and set canbus, bt, etc

5) install McuUnmatchUnlock.apk and unlock to remove version mismatch -01 error

at this point MTCE_HA_v2.99 successfully replaced MTCE_LM_v2.88_1 (but i see not noticeable difference - certainly none of my problems solved)

6) install latest HA OTA system update (still to verify if can be installed directly over LM system or requires base HA first)
[MTCD Android Head Units General] typos1:
If youve read the entire thread it should be obvious if any one has tried flashing another MCU onto an LM unit or not and whether its been successful or not. I think (and this is from memory, I m not going to re read the entire thread) 2 people have installed an alternative MCU on an LM unit one was successful and one was not, whether they used HA MCUs I dont know. If some one has tried another MCU they are not necessarily going to list every step they did to install it as you have done they would just say "I ve installed a different MCU using the instructions in this thread" or "I ve installed it and it works/it doesnt work" they are not.

They definitely are not going to write point 6 cos the ROM is totally irrelevant
[MTCD Android Head Units General] gwaitsi:
i think you've made it clear why there are 64 pages in the thread
[MTCD Android Head Units General] typos1:
I really dont know what that supposed to mean, the info you require is in the thread, many people have used it to change their MCU, its a helpful thread, you seem to be over complicating things.

If I were you I d try the very latest LM MCU and if that doesnt sort your problems try another, the best type to try first is the one that the member in this thread said was successful, if that doesnt work then try others.
