You have to downgrade to 1.5 first. Then you should upgrade to a newly hacked fw so you can play PSX and get the features of the new fw.
You can play both roms and UMDs on 1.5, but some games require you to have a more updated fw. You cannot play PSX on 1.5.
edit: This is the way I did it about a year ago. There may be better ways of getting to the new FW now without downgrading.
