Yes, you can reflash using FlashPro without using a laptop. See http://www.hondata.com/help/flashpro/up ... ration.htm
- Plug the FlashPro into the desktop. (Install drivers if necessary).
- Upload the calibration.
- Take the FlashPro to the vehicle, plug in, switch on ignition.
- Press the program button for 1 second.
If you need to first lock the FlashPro to the vehicle it can be done as well without a laptop, but requires additional steps to first record the vehicle VIN, and then lock the FlashPro to that VIN.
