Why isn't my phone charging, turning on, or updating/restoring

Hello

ive had this problem with this phone that was given to me from my friends friend.

whenever you plug it in to charge anywhere it shows the apple logo for then goes straight to the iTunes thing with the charging cable pointing to it (ive never used an iPhone)

it never turns on when ever its off the charger, and when it does it just goes back to the beginning

it also doesnt restore or updates, an error always comes up

ive tried all the resetting things like the DFU mode and hard rebooting, still does the same thing

please help?
