SV06-Plus firmaware and Creality Sonic Pad connection

I seem to have screwed up with the instalation of my SV06-Plus . All it keeps telling me is cant find the MCU , and asks me to generate printer firmware , then when I do Micro controller architecture says Atmega AVR , Processor model atmega 2560 , Processor speed 16MHZ comuncation interface UARTO and baud rate for serial port 250000 , press generate and I see ! failure . Can any body out ther help me , someone reached out here on the Forum but has dissapeared off the face of the earth ! I live in hope, non priniting Harry

Hello,
Can you explain how you perform the firmware update?

This wasnt an update it was the first instalation to get my printer up and running with the new Sovol touchscreen 5.0 .I follow the program that tells me put in this etc and always comes to an end when it says ,Klipper has found an error ,A FIRMWARE RESTART may fix the issue ! Time and time again I get this

And it could never find the port when I wanted to transfer the data to the mainboard

So try to reinstall the firmware of the printer and install the ch340 firmware on your PC
