I have 13 devices (S9j) and I changed all 10 of them successfully to Braiins-OS.
The problem is my other 3 devices are not accessible after install! It seems the network cannot give IP address so connect, disconnect every second.

p.s. All 3 devices are new! and bitmain 2019 series, but other 10 devices 2018.
p.s. All 3 devices worked perfectly from SD with Braiins-OS.
p.s. I'm trying to install latest Braiins-OS.
p.s. When I installed to NAND from web interface process completely successful.

Also I did set static IP address and pool settings and then boot from SD (with the same IP I had set up.), then I logged in to web interface and installed it to NAND (System > Install Current System to Device).
The installation process had completely successful (in report log there is no IP shown!)
finally when switch back jumper to NAND and turn on device the problem is still there!

The device fan speedup 5seconds and again slow down. Lan LED light is connecting and disconnecting in every second, so I cannot connect to device from anywhere(web & ssh).

I wrote this information maybe some one knows what must I do?
any help or advice?
thanks
