Hondata

You need to first select 'return ECU to stock' and let it upload to the ECU. Then select 'unlock from vehicle'.

So how do you unlock the hondata if the message "error authorizing VIN unlock" keeps coming up. I have tried unlocking it dozens of times like it was suggested but its still not working.

What is the FlashPro serial number?

serial # FP-SI-US-12846

Try it now.

I am completely unable to unlock the Flashpro. I’ve already reflashed the ECU back to stock with ease but when it comes to unlocking the Flashpro it keeps telling me it’s unable to authorize my VIN, check my internet connection. I’ve had multiple different sources of internet connection and nothing has worked. I’ve traded in my car and I need to unlock it ASAP

Would you mind telling us the serial number? Are you sure you are returning to stock rather than uploading a stock equivalent?
