:-\Unless I am totally missing sumtin which may be possible, but from my experience this "Custom Antminer s7 Firmware" Doesn't Work At All.
It appears to just be a bloated non-functioning Antminer S7 batch 1 firmware copy. It even has the "ping 114.114.114.114" line in /etc/init.d/cgminer.sh NOT commented out.
I do not know on which software you are riding your machine but a line with 114.114.114.114 does not exist on my custom firmware.
How do you upgrade to my firmware? Did you use this steps?
1. Clicking on Status
2. clicking on upgrade
3. choose the image file
4. click on "flash image"
5. reboot

Please do not use this steps until I have an answer for. thx
