How to enter service mode (officially known as Manufacturing Mode) on PSP Go

Connecting a PSP Go Multi-connector plug to a TTL serial adapter:

• Pin 24 connected to any ground (see pinout below for ground pins)
• Pins 14 (TX, from PSP to host) and 17 (RX, from host to PSP) connected together for k-line communication with your favorite 1.8v level serial adapter
• Serial adapter must have 1n4148 diode with line toward it's TX, other end tied to RX, and RX going to Go pins 14+17
• Ground connected between Go and serial adapter
• (optional) Pins 20 and 22 connected to +5v power source

Plug in modified connector to PSP Go while fully powered off (NOT in sleep mode), Syscon will begin serial communication with your serial adapter. Use PySweeper on PC to enter service mode.

Explanation

• Pin 20 Makes it think it's on cradle with 5v psp adapter conected
• Pin 21 Makes it detect a cable is on
