RN31400 cannot start (Urgent, please help)

I have powered down the RN31400 through web normally for a few days. I press the power button to switch it on today. Firstly, there is a welcome message 9as usual) display in the front panel. Then, it shows rebooting. However, after several secs, it freezes and display the message "mount_block_root +1f1". I long press the power button to shut it down and power it on again. The same situation keeps on.

Please help.

Regards,

Donald.

USB Boot Recovery may solve your issue:

  Thanks for the reply. It seems it is not a simple task to prepare the USB for recovery and not all USB will work. I am wondering what type of USB is OK.
  
  On the other hand, I am more concern about the data. Will the recovery process affect my data? Should I remove all the HDDs and do the recovery?
  
  Regards,
  Donald.

    Well it can be very simple to prepare but YMMV.
    
    If you want you could power down, remove your disks (label order).
    
    Though USB Boot Recovery doesn't touch the disks. Its sole purpose is to deal with issues related to the firmware on the internal flash.
