While the Pixel 7a uses Torx Plus screws, standard Torx drivers may still work. If your kit came with standard Torx bits, use the T2 bit to remove 1IP Torx Plus screws, and the T3 Torx bit to remove 3IP Torx Plus screws. Make sure to apply constant, downward force to prevent stripping.

Use a 3IP Torx Plus driver to remove the thirteen 4.3 mm screws securing the logic board cover.

Use a 1IP Torx Plus driver to remove the 1.5 mm screw securing the right edge of the cover.
