Rom for MTCB-ZD - MTCB Android Head Units Q&A

Hi all,
I currently have a head unit running MTCB-ZD-V2.83 Dec 02 2015 on Android 4.4.4. It is an Eonon branded head unit.
Does anyone know which ROM I can install on it? I want to expand internal storage because bigger apps fail to install but I cannot find an MCU for ZD to download!
Thanks in advance!

I cannot find a download for ZD MCU. Does flashing a ROM overwrite the MCU? Can I just flash a ROM from another unit and not update MCU?

As long as you only flash update.img it's OK. MCU is updated through a separate file, mcu.img.
Anyway, take a screenshot of your factory settings. While flashing ROMs these might get changed and you may have to make sure nothing has changed.

Maybe have a look at this one.

Help! KLD5 MCU firmware needed

I have a Pumpkin KD-C0109 single DIN Android 4.4.4 HU. I mistakenly upgraded the firmware thinking that I had a backup available but my MCU file was wrong. Does anyone have the firmware for a KLD5 MCU? the original MCU was MTCB-KLD5-V2.77.
Check here...

This is where I got into trouble. There are MCUs for KLD, KLD1 and KLD2 but none for KLD5. None of the ones that I have tried work. Now none of the buttons on my HU work, including the power button. This is a flip-out screen so there is no way to recover unless I can find the right MCU firmware.
K.. Maybe someone can extract theirs for you and pop it into Dropbox..
With that in mind, might have to keep bumping this thread until a kind soul comes to the party for you..
Then it could be just a matter of packing it into one of those other MCU zip packages and flash it.. Or someone zips it into a flashable pack for you.. I am guessing that using 7zip maybe work..but better confirm that with a developer..
Also on that note.. As been pointed out before... MCU flashing can lead to bad things happening as with these units not only using a rom + kernel but the MCU package as well ., thus if you are new to these units....
Read....read.. Check.. Before you do anything...

Please, kind soul, come forward.
Bump!
Currently the only way to get mcu is img from manufacturer
SOLVED
I was able to get a copy of the mcu.img from the reseller. [email protected]
I think I have the same unit you do but mine is branded as Eonon GA1312. The MCU version is MTCB-KLD5V2.79. Do you have a copy of the firmware you can share?

Universal 7" 2din android
Hello everybody ! I saw this forum yesterday, i found it interesting. I am also in trouble with my 2 DIN android 7" [ ebay item num.: 141797471889 ] .... After all connections made,
it only operates and shows up Android logo, after a moment only the light of the screen is on.....
I told the seller, and he sent me 2 files ( 4.4 MCU - 复件(3).zip & 4.4.4system - 复件(3).zip ) , i unzipped the files that he sent me, and he told me to copy only the 173 MB mcu file to the SD card.
So after all, i connected again the power wire , i pressed eject button and i inserted the SD card to the CAR DVD and I pressed the HOME & MENU button till it shows up an option . As he said...
Nothing !!!! I tried all the 4 files
( 1 mcu files from 4.4 & 3 mcu files from 4.4.4 )
Here are all, 4.4 zip file extracts folder: 4.2系统最新下滑MCU with file : 4bf18a00-297a-11e3-ab19-000c29ba27c0
&
4.4.4 zip file extracts folder: 2.9.5_SYESTEM800X480_CRO with files :
8baf147e-ea4a-11e2-b181-000c29ba27c0

Check the mcu thread

a couple simple questions before i brick my deck

XTRONS TD702A
mcu version mtcb-gs-v2.73
android 4.4.4_26082015
build rk3188-eng4.4.4 26082015.16:09:23
800x480 as per product webpage spec sheet
http://xtrons.com/td702a-android-4-...itor-with-screen-mirroring-function-obd2.html
i would like to flash Malaysk ROM. i believe i'm compatible but would like some reassurance before i screw something up. do i use update_4_4_4_FUSE_800X480_RK3188_12_MAL_13_02_2016. there is also a file Launcher2mtc3_JY.apk in the directory with update_4_4_4_FUSE_800X480_RK3188_12_MAL_13_02_2016, should i install that or is the stock launcher better?
i also see discussion about updating mcu. what does mcu mean and do i need to update mine with MCU_GS_2.55_Sleep_Musik or is my current mcu more up to date?
i assume there is no twrp for android decks?
thanks in advance for anything yall can teach me about my devise.

Yes, MCUs are not processor or OS specific.
Thanks a lot for this, can anybody guide me how to figure out which one of these I need to install. My device mcu version says: 023042bGS-CIC-HW7-180516[B1280_170325].
I Guess it should be GS

If your MCU does not start wth "MTCD" or "MTCE" its not MTCD/E unit, try the Android Headunit general forum.
Thanks I found the right one finally but the hu says please wait and news starts the process.

Can you share a link to the file ?
And post a screen shot of your MCU ? (it should b "v2.56" not "Vs 2.56").

As far as I know you can, but Sofia mdels have the wifi on the SoM, so the MCU may have some differences, do you have a copy of an older CHS MCU ?

No, I'm sorry, I don't have any copies. I bought it from a friend. What do you think I risk? I would like to try to update it because I have problems with Bluetooth or do you think it can solve maybe changing roms? But even I wouldn't know where to start, which rom I could put and how. Thank you

Usually all MTCD/E units use the same MCU and I was always under the impression Sofia units did too, but as I said they have wifi on the SoM which may make a difference as on other MTCD/E units the wifi is on the motherboard, so I m not 100% certain, also the link you posted has "Sofia MCU".
So I would read this thread starting at the beginning to find out for sure.

Hi, did you succeed with any update? ROM or MCU?
I have a similar MCU CHS 2.51, BT frequently needs a complete 10s-Powerbutton reset to work....
Tx!
Hi, I also have your same problem with the bt. No I have not tried to update I am afraid of breaking everything not being so heady

You could try changing the MCU to a different one - see @marchnz's "Verified Cross Compatible MCUs" thread.

Update MCU (PX3)

Hello! I currently have this version of MCU: MTCE_LM_V2.75_1
Is it important to update MCU? Are there risks? After the installation should I configure something?
From the radio I can not update MCU, it does not find any update. But in a post of this forum (Dasaita) I have seen an update is it compatible with my radio unit? MTCE_HA_V3.06.zip
I have a PX3 of 2Gb.
Thank you
I just found this MCU file: MTCE_LM_V3.01c20190111 better this update? I do not know what is the latest MCU version of MTCE_LM_V2.75_1
It's better to keep it up to date, even when you dont experience issues with the device.
The updates are normally not that hard to install and version 3 has the function of teleconference within.
I noticed with my upgrade that the device doesnt freeze anymore during boot. But i had 1.9 installed and now 3.00

Could you tell me what is the most updated version of this MTCE_LM_V2.75_1? PX3 2Gb. Thank you
I thought the rom for the MCU is 3.01 for LM, you can find those on the forum, only a good search is required.
I have the GS version but i do not recommend installing an MCU from another supplier.
The android PX3 2GB roms can be found anywhere. Search for PX3 ROM LM.

Your unit is not an MTCB/C/D/E, asking in the wrong forums. Read on.
This entire thread is a waste of space in that there are more appropriate places the OP could have posted in or at least searched first, but that's another matter.
I have a MTCE_XRC_V2.79k_1 which has the Intel Sofia cpu. What MCUs can I use?

MCU vs Firmware Cross Compatibility

Hi,
This might sound a weird question but can anyone clarify the following
I got a unit which has MTCE_CZ_V3.17_2 MCU (Wondefoo)
Can I for example flash it with MTCE_MX_V3.41 with HCT4_PX5_9.0_ota(20191125) MX/WITSON Firmware?
Or the best is to remain with original MCU?
Can I stay with original MCU and flash with other brand Firmware like HCT4_PX5_9.0_ota(20191125) MX/WITSON?
In short: can I cross upgrade with "X" MCU and "Y" Firmware or the MCU and Firmware has to be always the same "X" version?
What is the best option / combo? The MCU should always remain the original and can upgrade with other brand firmware or can change both?
Thanks

Take a look at wiki in my sig.
MCU and Android updates are completely independent. I'd recommend using the latest CZ update (3.4.1, per 4pda), exporting your settings to your USB/SD before updating, and then installing whatever Android build you want (based on launcher, newness, etc). Will work just fine as long as it's for a MTC MCU device and same SoC (ie, PX6), and has same base version (ie, 9.0).
Thanks for your reply @Matt Devo
Could you please send me 4PDA link?
If I install the latest FIRMWARE and MCU with option wipe cache and delete data, all installed apps which came from factory at initial boot, will stay there or not?
I want that all apps which came remain
Another question about MCU and CANBUS.
If I get same radio from different sellers, for example one has CHS MCU and other CZ MCU.
CHS MCU on factory settings page (126) on CANBUS shows BAGOO ALFA ROMEO, and all works, shows doors open and all.
CZ MCU on factory settings page (126) on CANBUS shows NO and all works but not showing doors open, but if I set BAGOO ALFA ROMEO, S.W.C. stops working and keeps not showing doors open.
Any idea?
That's strange

if you load one of the Android updates found here and wipe data/cache, you will lose any of the addtional apps your reseller preloads. Recommend to root the device and back those up first.

Can someone please provide me a link where can i download MTCE_MX_V3.41 ? I had tried on 4pda forum but i can't download anything, probably because i don't have account. I tried to make an account there but can't read the captcha codes in russian so i can register. Many thanks
