Upgrade My Cloud Ex4 firmware 2.11.140

I do the firmware upgrade, process 100%, the nas reboot and stay freezee…dont start…
what can i do?

i donwload from: Software and Firmware Downloads | WD Support

i upgrade manually…

must to unplug for 5 o 10 minutes, and then start again… it’s working…

but still have the same error…
i conect a usb drive, i get “Power Supply Failed”, and freezee the nas!

Is this happening with any USB drive, or is this related to a particular unit?

with any usb drive, pendrive, hard disk, diferent brad… :joy:
I HATE THIS NAS!!!
ES LA PEOR BASURA QUE HE TENIDO!!
