frontpanel buttons not function anymore after update

hi all!
i post for the first time in this section so apologize if i'm wrong or post in the wrong section.
I'm having issue with my RK3066 MTCB KGL 1024*600 HU (which commercial name is erisin ES9007a) since a ask manufacturer to send me new update to fix some bugs on my HU.
Since a putted in the MCU and update.img and make update, i lost my physical button in front and can't open front panel to access SDcar slots behind. Other physical buttons in front don't function anymore too like : vol+, vol-, power, eject....
I tried several other mcu find in the forum and i'm actually with : MCU v2.83 but i did no changes. I also tried v2.78 and v2.80....
The error i've done is that i haven't make any save before updating. Erisin don't ask me to do this.
SWC mapping is OK.
Anyone can help me please ?

You need to ask the manufacturer for the correct MCU.

Did you try and grab a few KGL mcu's from here? I would try a couple more, you should be able to use any of them.

i have tried 3 different MCU, should i try other MCUs ?

No, you should ask the manufacturer for the correct MCU.

1-DIN MTCB MCU needed

Hello,
I need a MCU file for MTCB KLD 1-din (flip-up) unit. Because of some issues that proved not to be software related I flashed the latest KLD MCU I found on http://huifei.fs-fileserver.de
Unfortunately, now the unit starts but I can't control the flip-up screen. The seller is not answering and I can't seem to find a MCU file anywhere... If anyone has it, please share.
Thank you!

I managed to receive a MCU file for my unit from someone at Pumpkin. Flashed it and now the unit is alive again. If anyone needs it, just ask.

No problem, just looking to help get in the right section and help for you.
Do you have details from Android system information, with that your head unit can be identified and perhaps questions asked

The unit is an AC8259 which is a MediaTek A53 unit. It is not a FYT, so the post should be moved to the general Android Head units sub-forum. I just requested that.
