Repairing the Joysticks in a OLED PS Vita (1000)

Basically picking up where I left off here:    • PS Vita 1000 (OLED) Screen Replacement   First video here:    • Diagnosing Another Junk PS Vita   The sticks for the 1K Vita are really expensive and unfortunately, the 2K sticks ARE NOT COMPATIBLE. Skip to the last five minutes or so if you just want to see replacing the actual thumb part in the joystick. And no I still have not found that little white part that fucked off on me.
