| Regard mobile TX (usual which is High potential), Can using multimeter to the metric data out , once the phone power on , you can get the voltage around 2.6v from phone USB, But sometimes you may get 2 or 3 potential, so if USB have so many pins this will be take much time to fiinish the job . so the easy way which contact your supplier give you the flash cable schematic :-)
Best regards !
