Reset network Settings iPhone 5 problem?

My iPhone 5 was jailbroken. I did a reset network settings since my network wasn't working for over an hour already. I got to the apple logo then it went all black. It didn't turn on. I tried doing hard reset but it didn't work. All it did was turned it on to the apple logo then turn off again. Would it be okay to just try and update my phone? It on an ios 8 right now.
