Put your original firmware in the USBKey and plug it
Put the cable named "key1" or "key2" to chassis ground and pint the reset hole in your radio (while the cable key1 or key2 are grounded)
The unit should start flashing the firmare in the USBKey, now you can remove key1 or key2 from ground
You sir, helped me rescue my TS18 head unit.
Thank you for this.
