How to enable SC20 in fastboot mode

I want to flash the individual images using fastboot mode in SC20, but I am not understanding how to enable SC20 in adb and fastboot mode in the first place. How will my system detect the SC20 as a fastboot device? I found this document where it guides to flash the images (last page)
but, I cannot run the commands because the device doesn’t support fastboot mode yet. Can someone help and tell me if I am doing it the right way?


This is an example of how to enter fastboot and flash the image.

Well @kevinzhang2020, thank you for the reply. The issue is I cannot detect the device as adb device, therefore I cannot run the above commands(No adb device detected). I think I am missing the required drivers. Can you help me with that please?

Can you show me an error?

Maybe you can try this command:
adb kill-server
adb start-server

@kevinzhang2020, I did try the above commands. But what I am saying is I am missing the adb drivers for SC20 device. I am getting the error as below,

PS C:\platform-tools> .\adb reboot bootloader
error: no devices/emulators found

I have to install the drivers I suppose.

Is your developer mode turned on?
