Zeek, what dashboard did you buy? Link?Thanks to all on this thread, today I received the oem dashboard for my ES4, flashed it, followed steps above and got it all unlocked!
The one last think is to figure out the serial for the ES4, but I don't think anyone has it yet.
Still trying to figure out if the purple dashboard can be flashed or if it is a lost cause. It already has bluetooth and I have the ST-Link and CP2012 but don't know if it is a lost cause.
