How to Enter Service Mode (officially known as Manufacturing Mode) on PSP-3000

Connecting a PSP-3000 to a TTL serial adapter:

  • Center pin of PSP battery connector is used for k-line serial communication
  • Serial adapter must have a 1n4148 diode with line (cathode) toward it's TX, other end (anode) tied to RX, and RX going to PSP battery center pin
  • (Optional) 10kOhm resistor between 3v3 and RX on serial adapter
  • Ground connected between PSP and serial adapter
  • Either supply 3.6v-4.2v over the battery + and - pins or plug a +5v charger into the DC In port of the PSP

Plug in your serial adapter to PC and set up [PySweeper] with the correct COM port for your adapter and the option for service mode selected. Plug in modified battery connector to PSP then connect power (PSP should not be connected to power before modified battery connector is attached), SYSCON will begin serial communication with your serial adapter and enter service mode.
