ipad keeps restarting, i can't update it
i have an old ipad mini 4 currently on ios 11.3.1 and stopped using it years ago because it randomly restarts after about 3 minutes of being on.
i've seen people say "update your ipad", but there's no way for me to update it due to it turning off and restarting even when the ipad itself isn't being used.
i tried hooking it up to my macbook to update it from there, but it restarts before it can finish the update through my laptop, even when the screen is off. what can i do? is the ipad just unusable?
