To pass 3.7.2 for 3.6.10 there is possibility?
 

I want to return to the old system without all the upgradings there is possibility?
3.6.10

Then why update?

Just get all the old 3.6.10 templates, and use them to over right the 3.7.2 templates and enjoy a board full of errors.

I prefer to return for 3.6.10 impossible?

Not impossible, but most likely, you will break your board trying to do it.

How I can return profile to the normal situation like in the old system?

Tpropil? What is that?

You can not downgrade a vBulletin board. Your only option for this would be to restore the backup you made before upgrading.
