Hi, sorry for noob questions but, I prefer this than asking if my dead Defy looks better on my room or the bathroom 
I'm currently running on 2.3.5 stock Movistar Latinoamerica, never upgraded (Already found a corresponding SBF), if something goes wrong, or I just want to come back, can I flash the the corresponding SBF "unlimited" times? do I have to get a matching Nandroid? Can I come back just with the Nandroid?
Thanks and sorry for spamming with this....... (I searched but I didn't found anything and the Defy Guide doesn't clarify everything.
Sorry for bad english
