Try only powering up the control board with no hashboards attached, if you can get into it then flash the s9j firmware onto it.
If not attempt to flash it again, it might not have worked the first time.
From the first time I already disconnected every other sockets, even once i tried without Ethernet wire , not getting any better its same
Try to find it using an network scanner such as
angry ip or nmap.
Alternative use the sdcard to boot
Braiins OS, and use (or install) that instead.
I tried IP scanner , it doesnt show anything
I will try with Braiins OS
If you shut down the miner while the leds are blinking there is a possibility that flashing process is not successfully flashed it means the program still corrupted.
What you need to do is flash it again with SD card and let the led red and green blinking until the miner will automatically restart itself and led stops blinking.
Now you can take back the jumper and power on the miner for 5 minutes perform this hard reset. Hold IPreporter/Reset button for 15 seconds then release then check it again with angry IP or any scanner to find the miner's IP.
But in bitmain site it mentioned when LEDs are blinking it means that firmware is loaded , but next step it has written power on control board although it didn't mention when to turn it off does it mean that i should wait until control board itself turns off?
