Need 1640B2.2 as CVT please

Hi guys,

I somehow screw up with my new Philips 1640 writer:
The writer is a bulk/OEM, not a retail version. Being annoyed about not being able to upgrade the firmware, I upgraged from B2.2 to 2.5 with WinDWFlash provided here (

Now, with P2.5, my drive won’t work at all anymore with CD-Rs.
Could someone help me out with a B2.2 CVT please so I can at least have the drive working, even if apparently suboptimal?

Thanks alot!

Brother Vlad
