Hello guys, i just bought a brand new non patched nsw (lucky me). it runs on OFW 4.0.1. Do you think it's a good idea to update to the official 9.0.1 before i use the sx pro? or should i just make a backup and keep the sysnand on 4.0.1 while using CWF 9.0.1? I see a lot of users having problems when using different versions of OFW / CFW. Thanks a bunch.
