Problem update PCM 2.1 Porsche 997 SW 1

[jetrider]

Hi,

When I want update my PCM the first CD (level A to B) doesn't work.

My SW is 1. Package CD update is 2009 Version Europe.

I think I must update to level A first but how?

Excuse me for my english, I'm french...

Thanks

The map 2009 it's ok but not the update to firmware up to 3.0 not work.

Do you have an idea??

Thanks
