45 minutos - 1 hora
I woke up one morning and noticed that my iPhone had been rapidly charging and discharging throughout the night. The charger was halfway plugged in. So that night I tried to charge it and it wouldn't work. I googled around and decided to fix it myself.
The repair went pretty smoothly; however the guide from iFixit wasn't totally accurate. It instructed me to remove the whole logic board, which just isn't necessary. The accompanying video from iFixit did not show the logic board being removed and I ended up following that guide. Everything went just fine.
Save your time and don't remove the logic board. Skip steps 13-19: They are completely unnecessary. Also make sure the connection between the dock connector and make sure it "clicks" in to the logic board. I also made the mistake of ordering the iPhone liberation kit AND a pentalobe screw driver and 00 Phillips. You only need the liberation kit.
