3. how to upgrade latest firmware to S2?
Now the latest firmware for S3 and S4 is ready to be released soon, that one for S2 is being developed. Stay tuned here.
The statement is 8 days old. Are we going to see the new firmware for our S3 units soon?
Actually, it's 2 months old......Here's a copy of an email I sent them earlier:
Bitmain & BitmainWarranty,
Why have you left it so long before contacting the cgminer developers?
Why didn't you work with them from the very beginning instead of trying to fork your own version using the older, vulnerable version?
In response to your "I will look into the S2 firmware" - this is the same as you've been telling the community for the last two months - IT DOES NOT TAKE THAT LONG!!
Bitmain has made no effort whatsoever to fix the redirect issue since May when it was first fixed. There have been 3 firmware releases since you promised to update your firmware - two for the S3 & one for the brand new S4 - all of which were still using the older cgminer version, so to say that "Bitmain has no intention of leaving the redirect open" is an absolute lie.
Bitmain hardware users are losing hashrate on a daily basis, and have been for the last 5 months because of your insistence on using version 3.12.0 - there can be no other reason for you doing this than to take advantage of the security vulnerability..
Why else would a miner manufacturer knowingly use this software?
Time to stir them up into doing something about it.
