I have two possibly basic question I want to ask. In guides for Rxtools setup, they tell you to place ReiNAND's firmware.bin in the 'rxtools/data' folder. In other guides (it seems if they have you do one, they don't have you do the other), they have you first launch PastaCFW on SysNAND (before even setting up EmuNAND/CFW) to "patch system signature checks". Can someone explain to me what both of these steps are for? Mostly the ReiNAND's firmware.bin step, because I'm not sure why you would use a file from ReiNAND if you are going to install Rxtools, and also because the guide I think I'm going to use doesn't mention PastaCFW at all, but it says 'for good measure get ReiNAND's firmware.bin and place in rxtools/data', but it also says 'Rename to 0004013820000002.bin if using the Nightly or rename to 0004013820000002orig.bin if using the alternate version'. I'm not sure what any of this is. I think that maybe this guide pertains to older Rxtools versions (i.e., not 3.0, because it has you place rxtools's firmware.bin in 'rxtools/sys', and I think this is only for Rxtools below 3.0), I think for now, I'm going to first install Rxtools 3.0, and then maybe try out ReiNAND afterwards. I really can't find the perfect guide for what I'm trying to do, as I am hesitant to try the one that mentions doing something with PastaCFW (mostly because I don't see why this is necessary). Please someone just help me with all of the confusion! EDIT: After checking the guide more, I don't think it's for older rxtools versions. I'm so confused, because all of these guides are so conflicting.
