Samsung Galaxy Tab 2 10.1 CWM Problem

Hello Guys,

I'm trying to root an Samsung Galaxy Tab 2 10.1 for someone I know. But I've got a few problems with it!

Things I've done already:

- Used Odin3 to flash the PDA CWM File.

After that it restarts, tried to enter recovery but it is just stuck on the Samsung Logo....Sometimes I manage to get in recovery, but then it says 'lunfile' missing or something like that...
