			There is always a way around. To use sd card slot and initiate a connection 
to upgrade server. It has to connect to wifi router, exchange handshake 
steps, log to remote server, do the task... 
I assume no difference if something starts from device itself or sd card. 
At least I installed my dedicated server from usb stick, containing just 
basic things. Then I fetched libraries from remote server. Added parts 
the same way. Should work for every device around the globe. 
Best regards all.
