MTCD unit, a question about which ROM's I can use.

I have a MTCD unit from Erisin, info in attached pic.
I see threads like this one Factory firmware for RK3188 MTCD
with links to firmware, can I use these?
How do I identify which firmwares I can use.
What do the letters after the MTCD mean in the MCU version, my letters are "LM"
kind regards

You can flash any LM update
Sent from my SM-N920C using XDA-Developers mobile app

I was told you can flash any mtcd firmware, just don't flash the MCU if it's not for your version. But I haven't dare try it yet.

same question

Do not use the ROM from here.. that is not mtcD head unit

Hello,
I have PX3 unit with MTCD_MX_v2. 56b Fw - and my question is, can I use MCU update from the PX5 versions which is 2.9 sth?

MCU and PX3/5 are two different systems. You can only use MX MCU with the MCU, but you can flash the PX3 board with any ROM you like provided it's for your resolution and you have enough RAM, especially for ROMs based on Android 7/8. As far as I'm aware only upgrade to Android 7 if your PX3 has 2GB of RAM and Android 8 is only for PX5 units.
Plenty of custom ROMs for PX3 such as the Hal9k and Malaysk. Or you can always flash a PX3 ROM from another manufacturer, results may vary though.

Well. the model is PX3 meaning if I'm correct 4 cors, PX5 has 8? Sth like that. And the MCU version is MTCD_MX_xxxx. So From what U wrote, I can safely update that MX which came from PX5 modles?
Another one - If I use any custom ROM, does it also updates the MCU version? Or that is separate stuff?
Thanks for help!

PX3 is 4 core, PX5 is 8 core.
PX3 comes with either 1GB or 2GB of RAM. 5.1.1 runs fine with only 1GB of RAM. 7.1 should have at least 2GB of RAM.
PX5 comes with either 2GB or 4GB of RAM. They have been only 6.0 but 8.0 is now out for them, 2GB of RAM should be enough for 8.0.
MCU is a separate update file to the ROM. The ROM contains Android and the UI you see. The MCU is specific to the board in your radio and requires the correct file such as KGL, GS, MX. Some are interchangeable but it is strongly advised against using other MCUs unless you already have an issue with your current one that isn't resolved by the latest version.

[PX5] MTCE New MCU 2.95 HA available

Hi there,
attached is a new MCU v 2.95 which I found at 4PDA.
It is a HA-MCU.
I succesfully flashed it on a Witson unit (MX2) and unlocked the MCU afterwards.
All settings working fine for me.
I found a new setting to display battery voltage is the status bar.

Can I try such an HA MCU IMG on a LM PX5 unit or can this brick my LM PX5?

You should have a copy of your current MCU to be sure.
I didn't have one so I just tried at own risk.
Important is to first install the mcu unlocker app, than save the dmcu settings (I additionally made photos of all settings).
Then flash the mcu, do unlock and set your settings back.
I manually changes all settings. Was also fairly quick job.
I can't promise that it won't brick. So if your system runs fine, I would not suggest flashing as long as no one confirmed compability.
lets say I am 95% sure, it should work, as most other users suceeded also with changing mcu. Finally its up to you.

I have tried and can download all kind of LM MCU versions for my LM PX5 - no problem.
I think I wait for some more opinions / experiences if MCU images of different PX5 unit vendors can just be used on every PX5 unit, or at least don't brick the device so I can change MCU back.

Refer MCU cross compatability thread.

OP can you give some more info and link for mcu unlocker app please?

Does anyone have a newer Firmware or MCU versions?

Does anyone have a newer Firmware or MCU versions for HZC,
above MTCE-HZC-V2.94bp from CS-X ?
i want to upgrade mcu and OS version for my PX5 , running old Android 6.
thanks.

I'm aware of a V3.30_a1, maybe someone can upload a backup from his device

A backup of MCU, how.

@marchnz no clue I thought it should be possible to do some kind of backup copy...
Any other solution? Should i give HA a try?
EDIT: Background, I want to update from Android 9 to Android 10 and install Hal9k. But what I did was to downgrade my V3.30_a1 to V2.94... Don't ask me why I thought it is higher that my previous version

If everything works for you, then I do not recommend crossing the MCU. Try to write to the seller, maybe your update will send you. You can find everything about Crossing MCUs here, if you don't find a suitable type of MCU, then you can lose more than you gain. I recommend using the search engine and you will find a few HZC users:

PX6 RK3399 MCU MCTP JP??

I'd like to ask the gods on XDA if they've seen my PX6 model?
I can't find the relevant MCU on the Internet
I asked the installation shop
But they're just agents
They don't have the relevant software for me to use
My current experience with Hal9k Mod v4 ROM is good
I wonder if I can update the MCU? Or upgrade the Android 10 system

This is the first MTC(P) I've seen, it's and MTCD unit. Refer MTCD sub forum.
What is your need to change the software or MCU code? What do you want to achieve.

Thank you for your reply, I want to know if I can update the MCU version? I can't find related posts and software to update MTCP JP V3.12_1
Maybe the MCU version firmware software is higher than 3.5?
I don't know
Or update to Android 10. Which ROM should I use is compatible or correct?

I have seen the above MCU, but I don’t know which one can be used?

I couldn't find a JP MCU either. Any of the MTCD/E/P RK3399 Android ROMs will work.
I wouldn't change the MCU unless there's an issue.
If you must update MCU, you might check with the reseller. An option could be, with at least a copy of the same revision JP MCU, to try another MCU such as GS or HA. Take a config export first.
See the MCU cross compatibility thread.

Problem with mcu update on android radio

Hi, I have a problem with mcu update in android radio, namely yes:
- radio is eonon d5103
- I can't find the update files anywhere, because there are some "specific"
- the mcu bone from what I read is stm32f101
- blue screen saying "mcu upgrade process began..."
i'm counting on your help, and a picture of what is displayed i'm posting below

Is it MTCD type unit, I think not and posted in wrong g forum, but post mcu version from Android system information
eonon d5103 is made up model name, no one will know what that is
