All ports were functioning properly yesterday until "rpi-update". Then after reboot, they stopped functioning and red light started blinking. I changed power supply. Red light is stable now but ports are not functioning.What should i do?

  • What about the Green LED? What is that doing? May 24, 2015 at 12:16
  • It flashes when rpi is booting. On boot, i cant see my ip that i assigned earlier..

I've read something before that newer kernels cause this exact issue. Try reverting back to an old kernel or wiping your card and downloading a fresh, new image. If a new image doesn't work (It should), go for an old one.

Also, something might have messed up the update. Do whatever you can to reconnect the pi to the internet, and run the update again. Wifi should work on one of the ports.
