Hi there, This guide has been edited to follow GBATemps rules on copyrighted material, this is an editted version of my post on that iso site. I also hope that this helps any community member that is looking to fix Frankenfirmware. I did some testing on a theory after I had after the downgrade on several N3DS' crash with the "Error Has Occurred" screen. It is possible to finish the downgrade without upgrading back to 10.3 provided you have access to oothax. In theory this should work for Cubic Ninja/Ninjhax but I did not own it to test with. I tested this on 3 3DS's. I still would recommend that you have a hard mod anyway if you desire to test this yourself. I am also not responsible if your 3DS bricks after following this guide. The only thing I will assume in this guide that you know how the homebrew launcher works and where to copy the files seeing as you've attempted to downgrade at least once. Requirements: Another 3DS with Homebrew access OoT3D Homebrew Starter Pack (if you don't already have this) MiniPasta Sysupdater CIA w/o memchunkhax2 FBI .3dsx The 9.2 CIAs for your model and region of 3DS (You'll need to find this on your own if you don't already have it) Paitence Step 1: Installing oothax with another 3DS A. Launch the homebrew browser on the secondary 3DS and navigate to oothaxs installer. B. Go through the prompts until it asks what type of 3DS. When prompted, select your 3DS model, 9.2.0, the browser from your previous firmware (so 24 for 9.6.0-24), and then your region of 3DS. C. If it succesfully installs, you can move onto step 2. If not, you need to wipe the saves from your OoT copy by launching the game while holding a,b,x, and y. Then start over from part A of step 1. Step 2: Launching minipasta and installing CIAs A. Launch oothax on the 3DS with Frankenfirmware and navigate to minipasta and launch it. Minipasta may take a few times to actually patch signatures and reboot, if it freezes, shutdown your 3ds and try again. B. Once minipasta has sucessfully softrebooted back to the home menu, launch oothax yet again. C. Navigate to FBI and launch it. Use it to install sysupdater.cia D. Once that is done, reboot the 3ds and move on to step 3. Step 3: Launching minipasta again and running sysupdater A. Launch oothax again and launch minipasta. B. Sysupdater should be on your home menu, launch it. C. Press Y to downgrade. It should only install a few titles and then reboot the 3DS. D. Congrats, your 3DS will have a downgrade that will allow CFW access! You can check using Downgrade Check, there should be 1 title listed as an extra and 4 listed as mismatched versions. This is launched with the homebrew launcher. This what Downgrade Check should look like for US consoles This is a video showing that my N3DS can indeed boot to Reinand after setting it up I want to thank several people, they are listed below. Smea for providing the homebrew launcher svanhuulen for providing Downgrade Check Derrick for introducing the idea of Memchunkhax2 Steveice10 for producing a working build of Memchunkhax2 and FBI Zoogie for posting minipasta profi200 for sysupdater That iso site for the post with the proper CIAs for downgrading Nintendo for leaving vulns in OoT And finally, my best friends Jesse and Josh for letting they're N3DS' be my test subjects EDIT: Edited to reflect downgrade check findings. Added Video launching CFW and Downgrade check photos as well.
