Chosen Solution
I recently found my 3DS after I losing it in the house somewhere for a while. I tried booting it up with the SD card inserted into the 3SD and it downright refused to show anything on the screen, no sound, nothing. I tried booting up the 3SD without the SD card inserted and it booted perfectly fine as I have Luma CFW installed to the CTRNAND via the Boot9Strap method. But everything I need is on the SD card, this includes all my games, FBI, Luma updater, and Checkpoint. I have tried removing the battery while the console is turned on. (Not the best idea) I have tried recovery mode to update the firmware. I have had a look to see if any cables are loose. I have tried letting it boot up for 10 minutes. I have tried changing the boot.firm file to the latest version 1.9. (as of this post) The SD card is formatted as FAT32 and shows up without issue on Windows.Any help would be appreciated.
I managed to fix it after playing around for a bit. I will keep the post up, so if anybody else has the same problem, they can try and and fix it.NOTE: If you do not have CFW setup to the CTRNAND (CFW without the SD present), this fix wont work.1. Remove the SD card from the console.2. Boot into GodMode9 (Hold start while turning on the console).3. Hold R+B until you get a message stating “Initialising SD card failed! Retry?".4. Insert the SD card.5. Press A.If the SD card successfully mounted the issue should be fixed.EDIT: More concise and easier to read.
Steps to fix- If your Nintendo 3DS touch screen is irregularly responding to input, you may need to recalibrate it. To do this, go to System Settings > Other Settings > Touch Screen. Here, touch the center of the circles with the stylus. You can also launch this directly from boot by holding down the Power, L, R, and X buttons. If you use a screen protector on the touch screen, take it off. While you might want a screen protector on your phone, they are known to reduce the input sensitivity of the 3DS screen. Also, try to use the stylus when possible, rather than your finger, to ensure consistent input. Greeting, Rachel Gomez
