Before sealing the display in place, connect the flex cables for the display and fingerprint sensor, and then power your phone on.

Test all functions to make sure your repair was successful before sealing up the display.

When fully inserted, the white line across each flex cable should be even with the markings on the motherboard on each side of the cable.

Do not remove, insert, or adjust the cables while the phone is powered on.

The cables can be tricky to align and install. Be sure not to touch the gold contacts on the back, or your finger oils may cause a malfunction. If you do accidentally touch them, wipe them gently with isopropyl alcohol.
