I have tested this firmware and its a HACK, WARNING! it installed 2 new pools that you do not see in the setup, and they prioritize mining even though you get some blocks the hidden pools receive the most, I tried to disable them, but the firmware will not allow it!

pools used are -> suprnova:9991 and dash-eu.coinmine.pl:6099

BEWARE unless this developer comes clean I would not recommend using this firmware!
