ETC Firmware Upgrade Instruction

Dear Customers:

Thanks for your continuous attention and support to YM products.

– All YM products will support ETC upgrade. The YM ETC firmware has been tested. (YMC01/02ETC miners no need to be upgraded).

– YM will provide customers with free firmware, and the hashrate will remain the same after the upgrade.

– YM will only support a one-way upgrade of ETH to ETC mining. Once upgraded, it cannot be transferred back to ETH mining (the customer will be responsible for the losses caused by not following the upgrade instructions).

– It is strongly recommended to upgrade 1pc or 2pcs machines and make sure the ETC hash rate in the pool is normal before upgrading for more machines. Faulty operations will lead to damage to machines and returning of machines to factory for maintenance. 

– For key account customers who want to test out the ETC upgrade in advance, we can provide remote support, please get in contact with us


– For more details, please refer to the attached instruction below. Please be sure to read the instruction carefully before the upgrade. And follow the right procedures while upgrading it.  ETC firmware will be provided after POS.
