Hello i got and antminer T9+
i tried to firmware update it with a custom firmware. I am doing it from WEB and when it says that update success . wait for reboot
i wait and then i can log in , root /root pass is not working .
Then if i remove it from the power and power it up again .it has the original Firmware and the pass root.root working

I also download the latest from Bitmain.com and i have the same problem

any idea ..?

DO i have to change any jumpers for update it?
is there a way to update the firmware throught SSH ?

i have done updates on my L3+ and my D3 ..and was working perfect
