I just downloaded the X10 firmware for another project. I'll take a look and see what I can find out. If someone would like to give me access to one so I can snoop around a live system I'd appreciate it. I can teamviewer into a PC and then ssh to the miner from there.
0.2 BTC from me as well, but for someone who could modify the A3 firmware to mine Blake2s instead of Blake2b, To mine Verge.
Probably not possible..
