WD TV do not start after trying to upgrade manually

I was trying update the firmware manually, according to the instructions. I put the USB Driver with the file in it, when the WD TV Hub start booting keep the message “upgrading the firmware” forever. I try different work around and any these works. Right now I can boot my wd TV hub.

Any ideas?

I’m glad to inform that I can solve the problem myself.

The solution applied was to format the USB in format Fat 32  and run the process again
