  • Insert a metal spudger between the right edge of the display assembly and the rear panel assembly.

  • Rotate the spudger away from you to release the tabs along the top edge of the display.

  • Insert a second metal spudger between the top edge of the display assembly and the rear panel assembly to keep the tabs from snapping back into place.

Add Note Edit Step 3  ¶ 

  • Continue prying the display assembly away from the rear panel along the bottom and left edges of the iPad.

  • Use extreme caution as you approach the top edge of the iPad. The digitizer ribbon cable is located near the edge of the rear panel and can easily be damaged.

Add Note Edit Step 4  ¶ 

  • Lift the display assembly away from the rear panel assembly by its bottom edge.

  • Do not excessively lift the display assembly off the rest of the iPad, as a fragile antenna cable with very little slack still connects the two components.

Add Note Edit Step 7  ¶ 

  • Use the edge of an iPod opening tool to flip up the retaining flaps holding the digitizer ribbon cables in their sockets on the logic board.

  • Pull the digitizer ribbon cables straight out of their sockets.
