If I put my phone into DFU mode to check what bootrom, how do I get out of it, and will this cause the phone to lock sim card/emergency mode? Because I don't have a ATT sim card and I can't activate it back.

You can enter and exit DFU mode without making any changes to the phone. Just hold both buttons for **FIVE BILLION SECONDS** , make sure to leave in your will that your grandchildren should then be able to turn on the phone like normal.
