Yes to +G, looks interesting
I use Google to host my photographs.
I tried heimdall, it would only run to completion a couple of times.
I tried reloading the drivers through heimdall.
Error Mess: "ERROR: Failed to access device. libusb error: -12"
ran miuniastable1.tar version heimdall, successfully, however the phone would not turn on.
This is where I'm at.
