I haven't used it in years because it's not the current phone I'm using, I had to do a phone update because it's been about 2-3 years since Iv used it couldn't even read my sim, kept saying no service, but when I updated it, the device just turned off and went to that screen where it has that logo to show you it's updating but afterwards when I wanted to turn it in it just kept showing the Nokia logo then to battery flat logo, what should I do?
