Firmware won't flash, any specific instructions?
Yes. What I said.
Set your difficulty manually to 2048 on whatever pool you are mining at.
This will avoid a portion of the ill effects of the current firmware.
Aside from that, wait for Bitmain to get their sh*t together and support their products properly.
This is very disappointing.
The S4 should not have been shipped with this firmware.
Providing a firmware package days after release which will not properly flash only adds insult to injury.
I can't imagine how much BTC is currently being lost by inefficient and improperly configured miners, helping to further kill any chances of ROI for many many people.
Nevermind the security risks involved with running the outdated 3.12.0 version of CGminer forever.
Yep, been running at 2048 since I got it. Only way to get good results out of it, can't trust vardiff which works 1 out of 5 times. I'd like to get this firmware flashed, though.
