Parts list calls for:
iPhone 5s Logic Board Grounding Bracket and Contact Clip
not sure why.
Instructions at link for these parts says they are "visible in steps 53 through 56 of the Upper Component Cable Replacement guide". Not quite right.
- Steps 56 & 57 show removal of the Logic Board Grounding Bracket, but instructions call it the “logic board antenna bracket”. Screw that goes through the logic board into this is marked in red on step 30.
- “Small metal contact beneath logic board” referred to in Step 30 goes under the Logic Board Grounding Bracket. See also Step 34.
- Step 59 shows removal of the Contact Clip.
