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 powered off, Syscon will begin serial communication with your serial adapter. Use PySweeper on PC to enter service mode.
