[SOLVED] My 3ds is an Old 3ds XL (USA) I followed this guide: https://plailect.github.io/Guide/ My current problem is that my 3ds black screens when I boot with my SD card, but loads fine without my SD card. I've googled my problem and tried finding other threads. I've tried deleting the home menu extdata I followed this troubleshooting guide: https://plailect.github.io/Guide/troubleshooting#ts_sys_down I have a nand backup but I'm not willing to hardmod. I can boot into recovery mode, but I don't want to resort to that unless there's no other choice. Here's the specific details: I had my 3ds running CakesFW using menuhax (which auto boots) that I hacked about a year ago. Yesterday I wanted to update to arm9loaderhax and Luma3ds. I followed plailect's guide above for Old 3ds XL - USA My sysNAND was version 9.2.0-20U, so I loaded Decrypt9 from my browser (in sysNAND). Decrypt9 booted successfully, so I proceeded to the 2.1.0 ctrtransfer (https://plailect.github.io/Guide/2.1.0-ctrtransfer). This section is where my problem occurred: I followed the page exactly (as far as I know), got up to Section III - ctrtransfer, did everything, no errors or failures from what I saw. Got up to the last step (number 10), pressed (Start) to reboot, and I black screened. (I've included my Decrypt9 log) On one hand, I feel like the problem was that menuhax auto boots to emuNAND unless I hold L, but I did not hold L when I rebooted from Decrypt9. On the other hand, I feel like that should not have mattered, especially because I deleted the home menu extdata (0000008f) before the reboot (Step 8). So that's basically what happened. I've included the ctrbootmanager config if that helps. My microSD card is samsung 32gb If anyone has any insight, that would be greatly appreciated. Thanks for reading this far.
