I don't know what kind of problem I'm having, in fact, I've tried many times to get the system update to work properly via USB flash drive only by following the order as described above, and it's the same every time.
If you follow the order of the instructions, it will stay at the initial stage forever and do nothing.
My usb flash drive was purchased new and it went through a proper formatting operation, though I can't rule out that it is perhaps faulty?
I will try another usb flash drive if I get the chance!
Same here. Updating via USB never worked for me. I'll try this trick next time.
