re: Issues with S2 firmware, have you considered running Kano's firmware ? I've been running it since shortly after taking delivery and haven't had any issues with my S2's.
My S2 with kano's FW doesn't save settings on reboot. If you know how to fix it - please share this knowledge with the community.
What are the problems you are seeing with your S2 ?
Hmmm... Even kano's firmware contains old cgminer (I said about settings above). Do you need any comment on it?
