Hi, I currently am on 4.75 OFW with my PS3 Fat CECHM03 and want to downgrade to 3.55. Im looking online with below link to buy an E3 lasher but there are alot of differen types. some with 4 parts, some 5 parts, some 11 parts etc etc. I have no idea what the differences are. Is anyone able to explain to me and let me know which one I need for PS3 Fat CECHM03 on OFW 4.75? http://www.aliexpress.com/w/wholesale-e3-flasher.html Thanks!
