This is what I did to get my a9lh to run on my N3DS. Edit: before you read further I want you to know I already have Aureinand 3.14 installed on the sd card 1. I put the minipasta.3dsx in the 3ds folder on my microsd root 2. I used menuhax to boot the homebrew loader, than I booted minipasta. 3. After booting into minipasta I went back to the homebrew loader and I booted my a9lh, after a9lh was done installing and my 3ds shuts down (that's normal). 4. After all that I downloaded the arm9loaderhax.bin, I went ahead and put it on the root of my sd card. 5. Then I went and turn on my n3ds (with the arm9loaderhax.bin still on the root of my sd card), then I decided to let the 3ds run for a good 20 seconds and I pushed the A button. After pushing the A button the n3ds turned off (which means a9lh is installed properly) 6. After that I removed the arm9loaderhax.bin and decided to see if Aureinand would boot, but to my surprise it did not boot. Instead what happened was my n3ds turned on with the blue power light for one second and then it turned back off (this happens every time I press the power button). I did not change the name of the arm9loaderhax.3dsx, the name is still the same, and I did not change its location. Edit: I followed this guide from mrmario2011 on youtube Do I need to reinstall Aureinand? Or is something else wrong?
