Hello From Romania , This first question from my new 900BT ,
I buy from my friend this Europen version ( Buying from Italy ) but it is FW 1.0 ,
CAN I UPGRADE DIRECTLY FW.3.0 or ? i must firstly upgrade 2.0 and after than FW 3.0 must be ?
Which one the working version for the test mode ? and what can i do with it ?
How can i make one backup for the all systems files,
( If somethink wrong on upgrade after then can i use this back up ? and how ? )
