It's easy enough to remove the fees from all these illegal firmware.
The people who release them are really not that smart.
Of course I'm certainly not gonna support a bunch of criminals and help people use their firmware ...
So how does one redirect the dev fee. I'm actually using this firmware. I got a really crappy mine, I bought it second hand. Send to bitmain for repair, they scrapped it. I but I used a custom firmware and it sometimes works. So I can at least get some $, but I honestly need all I can get to stay alive
Re-directing or outright blocking the devfee address is not the hard part: the fact that the miner is also looking for those (sucessfull) connections and will stop mining when it no longer gets the correct responses when it tries to switch to the dev pool. In short, it is a software based license key dongle.
