Why do you think this is necessary? The error message you show would lead me to believe otherwise.I really need some assistance to rolling it back from Window Server 2008 R2 to Window Server 2008
As for how to do it, dynamik linked to the procedure, but you are looking at doing a full on restore from backup and rebuilding your entire ADDS structure forest-wide - unless this is a home lab or you have a couple dozen machines - it's almost never worth it - it's to be used after catastrophic problems/corruption/etc. -

I resolved the issue by entering a certain command in the powershell, you can only lower it from R2 to 2008.Bachelors of Science in Technical Management - Devry University

From what is sounds like, we aren't dropping a functional level, we are dropping from R2 to "R1" but I didn't know you could do that either.Decide what to be and go be it.
