To go back, you only need to start the P2.2 flasher.
ala42: You can't go back from P3.x firmware to P2.x with the official flasher.
The only option in this case would be to use WinDWFlash and a P2.x firmware in CVT format.
The dangerous Brothers care both the Philips 1640P v.2.x originals and RPC1 .CVT firmwares.
