Then unzip it. There will be another .zip inside, which you need to transfer to the root of your PFI's internal memory, without unzipping it.
Then unplug your PFI from the computer, and it'll detect that an update is on the memory and will ask you if you want to install it.
Also, be aware that you'll lose EVERYTHING that is on your phone, so please backup anything you want to keep before you proceed.
First of all, many thanks for your kind help.
I did exactly what you wrote, but could't move the Zip file to the Root directory of the Padfone. Android system just didn't allow it. How can I do it?
