Galaxy s 3 Update behind a very restrictive Firewall

Hi. I have a Friend, who uses a Galaxy s 3. He lives in a boarding school and has a very restrictive Firewall, through which he can access the Internet. They are using the astaro Firewall. Most Programms get blocked. Even the Windows Update. Nearly everything that is not using port 80. Even tor is blocked.
He is still on Android 4.1 on a German Firmware. Is it possible, to download the Firmware update on the PC and push it via usb onto the Phone, so it finds the needed files and flashes it up to 4.2 and later the same procedure for 4.3.
Thanks.
I dont want to root his phone, and just flash cyanogenmod, because he wants to still have his warranty.
Thanks
