Can you at least make it to the login page or the initial password screen, then to this main page with blank data?
If so, you have a few options
1st be to factory reset the S7 with a paperclip. There is a pin hole next to the Ethernet connector and use a paperclip and press and hold the button for about 10 seconds and let it go and wait for about 30 seconds and then physically reboot the S7. This may restore it to the factory default setting.
If this does not help, you may want to go find 8gb microSD card, and create a bootable MicroSD card and insert it into the microSD slot of the S7 and power it off and power it back on. Let the S7 complete the boot process and if possible, let it run as is for about 5 minutes then your Beagle Bone Black may be restored to the factory default setting.

Antminer S7 B10 not connecting to the setup page. Nothing is configurable, miner is inaccesible.

Ive tried resetting multiple times with no success, I can get to the login page but after 2-3 minutes I only get the blank page. I will try the bootable microSD option tomorrow and will report back. Thank you
