So I've had the same problem. Updated the firmware and now the unit is bricked. Red light flashed. I formatted a USB stick but I'm not sure how to install it? Just turn it on and hope for the best? I tried that and notice no difference.
Can anyone help? Do you hit reset button? Is there a factory reset setting?
Inside the download you will find imageUSB.exe and z1_static_100_09_14.7z files.
Extract the .7z file and you get an .img file.
Use the imageUSB.exe to burn the .img file to a USB stick.
That's all.
Yes I did all that. Then restarted it with the USB stick inside. The red light has gone but I've performed multiple IP scans and can't see the miner.
I tried rebooting it, rebooting my router, and nothing has made it appear in the IP list.
The Z1 is on different network, you need to be on 192.168.1.x network or change your subnet to 255.255.0.0
