10 - 30 minuten
Docking connector had a chunk missing and bent pins. Also my phone would die in about two hours of non use or less than an hour of use, so I had to carry my charging cable and an external charger everywhere.
Fantastic! My phone can now sync to a computer and charge with any cable. I had to have a specific cable that used the pins I had left to charge it. My phone can also go all day without being plugged in with moderate use.
Step 4 of the battery/docking connector removal and replacement was almost disasterous. The screwdriver from the iFixit toolkit didn't have the correct size and started stripping one. Luckily the screwdriver from the Liberator Kit fit perfectly.
Also Step 16 of the docking cable replacement was kinda vague, and I kinda stumbled on the retaining flap by accident. It was hard to tell what exactly I was opening from your pictures. I was actually prying on the metal for the docking port for a bit before I stopped afraid I was going to break it. I was just looking at it with the spurger when it hooked the flap accidentally. Then I picked up along like nothing happened, lol.
But putting it all together was the easiest part and after a soft reset my phone picked up the surrounding towers and had the correct time and date. Total success!
