I need help with iphone?

So about a day ago I got my phone wet and have had it in rice since then (no it's not just a movie thing, it's actually worked for me before). I decided to check on it (it still was all weird) and got a notification that told me if I didn't update it I wouldn t be able to use cellular data. So I did. I waited and waited until finally I was on the verification screen that takes up the middle part of my phone. It just stayed there for a long time so I put my phone back in the rice and waiting. An hour later when I checked it still was there. I tried turning my phone off but it literally wouldn t work. So I looked it up and it told me to do a hard reset. My home button is broken so I have the little button thing on. I can't do the hard reset, and now I have no idea what to do. Heloo

Take to a place that repairs iPhones. At the very least, you need that home button fixed.

What a dumbass… Prematurely taking it out of rice

What kind of a phone is it? Unless it one of the expensive flagship smartphones then it probably won't be worth fixing. Just get a new phone.
