I need some help I flashed the firmware of my second batch and I want to restore it.. how to do? On the bitmain website there is only the may version... I think that the old version gives some issues with the batch 2 ...
What issues

Tried factory reset???
The may version is completely fine on batch 2, i have loaded all my batch 2 machines with batch 1 FW
What speed are you getting with that firmware and where can I find the May firmware version? Thanks in advance!
