Yesterday I upgraded my 9 Antminer S7's batch 1 with Bitmaintech's newest firmware release. After a restart 6 of them worked fine. But the other 3 first seemed to work at normal output (appr. 4850 Gh/s), but within a minute speed reduced to almost 0 Gh/s and remained there, while the red light on the back kept on flashing. There has been no way to get them up and running normally again (reboot/ reset nothing helps) and I don't know how to reinstall the old firmware again, because I don't have it and it's not in the support section on the Bitmaintech website. Does anyone have similar experiences and/ or solutions or can anyone help me to get the old S7 firmware?
