So I recently bought the original PlayStation 3 model CECHL04 (PAL) on 2.45 OFW and wanted to put CFW on it. I watched numerous of videos and tutorials but got confused since there are so many of them. What I am wondering is how I should proceed with this? I understand that I have to upgrade it to OFW 3.55 via a USB stick, but then many tutorials said that I should upgrade to CFW 3.55 afterwards to dump the NAND eID etc.. Is that so I can have those as backups in case something bad happens, in order to flash it back? I don't have a flasher btw. I heard Rebug is the best CFW so far, so should I go with that one? Then there's the whole CEX, DEX, SEX, and REX thing.. I guess DEX is the one to go with? Any help would be appreciated, preferably a thorough step by step guide since I don't want to screw this one up by doing something stupid..
