I have a Yami Miner ow i need to mine ETC how can change.? I couldn't find any video or post about upgrading

Thank you for your email,

Unfortunately, there is no firmware update for miners that were purchased with hasboard v1 cards. Our company has developed a new version of hasboards usable for Ym-2100 and Ym-2400 Mh/s miners. These boards are Version 2.0. They are installed in miners that have V1 boards, and then you can use the miners to mine both ETH and ETC. The above-mentioned plates are:

YM-2100 Mh/s Hashboard V2.0


YM-2400 Mh/s Hashboard V2.0


For each miner, it is necessary to purchase 2 hasboards v2.0.

Also,for ETC mining only we have recently released a dedicated ETC miner,YM C-01/C-02
