Hello, sorry for my very bad english.
I have a Vonstar H618 box, I can't find firmware support for it in this list https://github.com/ophub/amlogic-s9xxx-armbian/releases?ref=armbian.io
I have downloaded the original firmware from the vontar homepage https://www.vontar.cn/pages/download.
I hope everyone can help me install armbian on my device. Thank you very much
