I imagine I am not alone in that I have recently setup my 3ds using Plailect's amazing guide and now run the AuReiNand cfw but am not an expert and would like some guidance on what to do now and in the future. Firstly I would like to clean up my sd and remove apps etc that I used during the guide but won't need now I have my otp and system setup: From HBL menu: 'Cakes' - seems to do nothing (but as I am running AuReiNand it ought not to, right?) - So can I remove the 'cakes' folder from the sd\3ds folder? 'OTP Helper' as I have the OTP can I remove this app? What about these: 'SafeA9LHInstaller' 'ironhax installer' 'menuhax_manager v2.2' 'miniPasta' - doesn't seem to do anything 'sploit_installer-oot3dhax' I would like to leave anything that might be useful in the future just want to remove anything that is no longer working, required or possibly disruptive. What is the best way to backup my system / sd card? Finally what apps etc do I need to keep an eye on and keep updated? I just updated AuReiNand to 4.2 and now have the nice option of showing the firmware in System settings. I wonder if I need to keep Decrypt9 and EmuNAND9 updated (is there anything else?) but I a bit out of my depth now... Thanks.
