Firmware for this yellow generic cheap ESC

[batata004]

This is one of the most sold ESCs in Brazil and I despite being very common, I cant find any reference pointing me to the right firmware to flash. Would you mind taking a look at the pictures below and guessing which firmware should I try to flash using BLHELISUITE?

Thank you and I appreciate the job you are doing for the community keeping this repo alive!

Fala Brother, vc conseguiu atualizar o firmware desse esc para o blheli? Parece que esse amarelinho usa o SimonK e quero muito usá-lo para reverter o sinal do motor.
