Please can someone give me the MCU firmware MTCC KLD6 v2.97 ?

I played with my new stereo and added bad mcu and now its broken, all my buttons and knobs do not work and the radio and wifi do not work any more either.

Please help. Thanks in advance.

Hi,
Sorry to hear about this.
Could you please first tell us your order number?
This information is very important for us to provide you best solution.
As you known, we don't suggest our clients do the firmware/MCU update from others, even the original, cause it may lead the function mixed.
We can send you the original MCU MTCC KLD6 V2.91, but we are not sure if it can help you solve the problem.

I do not have the order number because it was a presnt.

But my "about device" screen definitely said "MTCC KLD6 v2.97 MCU", please please, send me that MCU ?

Hi,
The link of the MCU MTCC KLD6 V2.91 is also the original firmware for your unit.
You can try to install it to check.
And we will ask the factory provide the MTCC KLD6 V2.97 MCU in case the problem is still unsolved.
But we are also not sure if the original MCU can make the unit work as it should, cause the bad unknown MCU may damage the unit.
Regards

I tried v2.85 but it does not help. Please can you get v2.97 ? Thank you.

Hi,
The MTCC KLD6 V2.97 is the strict file provided by the factory.
Normally we don't allow our client do the MCU update cause it may bring other problems.
But in order to help you and try to solve the problem soon, here is the link for you.

Only for all the people wondering why their radio, wheel knobs & buttons and also WIFI does not work
after updating the MCU

IT IS NORMAL in the most of the cases that these happens!
Everything is deleted if you update the MCU
Also your WIFI password and the wheel configuration for the buttons and knobs
=> AND also the Radio configuration in the Factory Reset Menu
that's the reason why everithing is not working after the update

so go into Factory Reset Menu with 126 and configure your Radio (one of the radios you can choose will work for your device)
Next enter again your WIFI passwort and the wifi will work again
next go to wheel configuration and set the button mapping again

THAT'S ALL
