Replacement of the upper case of MacBook Core Due

My Problem

some key board letters are worn out.

My Fix

I did it all right thanks to your repair guide.

My Advice

1. Step 8 of the repair guide: Phillips #00 works better than #000.

2. Step 6: I stripped the middle one when reassembling, but the driver ⊖1.0 worked all right to tighten it. Should be very careful as the repair guide mentioned.
