P2 Pixel activation in N/A

[GaryMuto]

Just installed the OTA to P2.14.3.  As expected my changes were wiped.  When I attempt to reflash to re-enable the pixel lights it fails with a negative response from CSD.  Any ideas?  Anyone else experiencing the same?

I took my car to a space for the 18,000 mile check.  I reset everything to OEM before the appt.  They updated the software for me when the car was serviced.  A few days later I installed my changes and everything seems to work as before.

Maybe you have something else going on?  interface cable maybe?
