Hi, My iPhone is stuck on the same screen of death/apple logo, everytime I try to start it up. Before it happened, it was really low on space (like only a few megabyte). Zero space prevents the phone from booting. This means that basically I have to reinstall the software and will lose all my data. I read iOS 10 takes up less space. Is it possible to install the new software, so there is enough space for the phone to start up? Please help - any advice is appreciated greatly.
