I tried shut my phone off then restarted it while holding the home key at the same time as the power key to see if anything different happened (it was stupid, I know) What I didnt realize was I forgot to disconnect the USB from my computer; not sure if this caused the problem or if it was me holding the home key down. Now my phone is stuck on a black screen with a picture of a phone with a red triangle and eclamation point on it. What the hell happened to my phone? I tried taking the back plate off so I can remove the battery but there doesnt seem to be a way to do it. It wont come off so I cant pull the battery and put it back in. Its brand new and Im freaking out. Can someone please help me!?
