So I used this guide linked below to hardmod my N3DS XL. https://gbatemp.net/threads/tutorial-noob-friendly-nand-dumping-2ds-3ds-3ds-xl-n3ds-n3ds-xl.414498/ I just finished the mod on the motherboard and I haven't plugged my modded sd card adapter to my pc yet since I do not have the recommended card readers provided in the guide. With these info, here are my questions: 1. Can't I use any other cheap card readers? I have an unbranded one that costs less than $1. I could buy a better one locally but the price of around $10 is out of the question plus it's still not amongst the recommended card readers. 2. Using my laptop.. Can't I just use the card reader available on my laptop? I mean directly plugging the modded sd card adapter into the laptop's sd card slot. 3. Assuming that I finally did everything on the guide (hardmod and plugging it to pc), how will I use these to fully downgrade my 3ds to 10.7 or much better to 9. 2? So far, those are my questions and I believe that more questions will arise along the way. Thanks everyone!
