Reading/Writing the EEPROM
Software Method
This is the easiest way to dump an Xbox EEPROM. Use your alternative dashboard to dump the EEPROM to a file and download it over FTP.
Hardware Method
If you cannot dump the EEPROM using software, you can dump it using hardware. You have several options: use an I2C host adapter (see here or here), build an I2C-Serial cable, or use a device like a RaspberryPi which has an I2C interface. Connect SDA/SCL/ground to the LPC pinout on the board. See here for pinout information. Then use the corresponding software to read/write the EEPROM.
