How to detect oled modchip?

[Keylogger]

Hi

Is there a way to know what modchip is installed on an OLED switch without opening the console?
I tried to use the hwfly toolbox and do firmware update option but it says couldn't communicate with hwfly.

How many different chips exist for oled?

Anyway to know if I have spacecraftnx fw or hwfly fw?

There is only one model, but few different version. You don't have to update the chip if you unit boot fine.
