I have a bad charging port on my Asus tablet and bought all the tools described in this tutorial. However the phillips screwdriver recommended is too pointed and will not unscrew any of the internal screws so I could not get very far. Very frustrating. Anyone know which one would work without buying a whole screwdriver kit?

Also, author shows removing battery in order to replace the charging port but wondering if it can be replaced without removing battery. Would save time and make it easier but I'm just guessing since I couldn't even get the screws out at this point.
