Ok so I finally broke down and purchased a switch. I checked and my serial number is XAW100677XXX which is safe to hack. I was wondering which ia the beat hack to use for themes and running cfw. My second question is if I make a nand backup before even attempting to hack my system and then install cfw will I be able to go online if I restore my original nand? I also wanted to know how long would that take and Im probably gonna get a 128 micro sd card for my switch
