Hello–I just did the iFixit battery replacement which seemed to go well. However, when I then plugged the phone in to charge, nothing happened. The battery did start to get warm, but nothing showed on the screen. And then the warmth went away also. I left it for a while but still nothing. I have just put the old battery back in, because the phone was working fine before all this. But alas, it still just sits there like a flat shiny potato. I’ve tried plugging it into the computer also, to no avail. What have I done!?!?
If your original battery used to work (just shorter lifespan) and now the phone doesn’t respond or isn’t recognized by iTunes, then you may have damaged the logic board while disassembling the phone. As Cameron suggests, if you used metal tools to pry the connector, you may have a caused a short on the logic board. You may also have dislodged or pried some small components. Unfortunately, working on a logic board is not a DIY repair unless you have the right tools and some experience. You should look for a repair shop that does micro-soldering repairs. Many of these shops have a no fix/no fee policy so you don’t have to spend money to find out if the phone is fixable or not.
