thanks a lot, I was able to write .hex to the controller. However now I cannot update the firmware now using KC868 Controller Bootloader tool, it cannot detect bootloader and not reacting to holding any switch.

when controller power on, MUST <5 second to click "detect" button by tool.

[v1rtus]

yes, I click the detect button <5 secs after power one, unfortunately it cannot detect a bootloader and no switch is working, is it possible to rollback the bootloader?

[admin]

do you have whatsapp number? i will let our technical support use "Anydesk" remote control your PC to help you download firmware.

[v1rtus]

there is no problem with firmware download, I have done it many times already! The problem is that controller only read light is on, it is not reacting to holding any button, I cannot access to it via serial or ethernet.

[admin]

because now only BOOTLOADER inside, but no firmware inside.

[v1rtus]

I am following the instruction, I have RS232 connect and Bootloader software running, after I power the controller I press detect bootloader but nothing happens
