How can I fix an error message on my phone?

My phone is a wiko Rainbow and for the past few weeks it kept messing around with "Unfortunately (literally everything) has stopped" almost every 3-5 seconds so I did a factory reset. I still have the same problem but WORSE! I can't get onto the internet, I have to remove the battery a few times before my phone will power up to home screen, I can do nothing with it. Any ideas why it's doing this or ways to fix it are greatly appreciated.
