Basically, I fucked my 2ds up. The screen is broken completely and I dont want to pay 60$ plus hours to try and change the screen myself. I still have the warranty and set up a repair with Nintendo Store. My question is, what can I do to make sure they don't know I had a9lh installed? I can get into the recovery mode to force an update but since the screen is completely worn out, I don't know where on the screen are the buttons to press.
