Need larger screws

Mon problème

Weak battery & broken case.

Ma solution

Fixed one 4S with a new battery and back case. A bit intimidated about fixing the second 4S with a new front screen and battery. 41 steps? Is there a trick to reinserting those microscopic screws? Found out that coffee is not recommended before repair.

Mon conseil

Make a large workspace. One battery screw popped out and onto the carpet....gone forever. Magnet didn't help.
