Hi there,
I have been trying to fix firmware issue for hours and I'm getting tired of it. I restarted the firmware upgrade (v1.8.80). The LED light was flashing Red-->Solid Green with the Beeping Sound (which indicates that Firmware Upgrade is in progress) then the BEEP SOUND stopped but LED light still flashing RED--->SOLID GREEN. It's been almost 1hr and still no beeping sound. Should I be worrying or send it to repair ?
