You need to downgrade first to get on a ofw/cfw 3.55. You need e3 flasher or other technique to downgrade. First you want to make sure that your ps3 is downgrade compatible. Look here,

Thats all the information i can give you, the rest you will find on google and youtube, there are many tutorials online which will explain clearly each step.
If you are not an experienced electrician, then i dont recommend proceeding, buy a ps3 on 3.55 on Ebay to save time and complications.
