I have been meaning to write this guide for a while. I held off on it for a long time due to the overwhelming amount of steps it use to take to spoof and downgrade emunand. Now that I am able to make it brick and idiot proof I feel as if everyone should have the chance to system transfer the easy way. Please try to keep questions to the guide and I will do my best to help
Requirements
O3ds 4.x-9.2
N3ds 9.0-9.2 (If on 8.1 update to 9.2
here)
This file pack
3dnus
Note to official 9.3+ firmware people, the only way I have found to transfer to n3ds emunand is to first transfer to another o3ds with emunand or custom firmware then use that to transfer to n3ds emunand.
Pre-requirements
You need to have emunand setup on both o3ds and n3ds and make sure you access the eshop at least once on both units. Make sure to make a backup of both emunands using emunand tool. Your n3ds and o3ds emunand must be between 9.0 and 9.5. If your 3ds has a higher emunand then 9.6 we will need to downgrade to transfer. If you have an emunand lower than 9.0 use 3dnus to download 9.2.0-20 USA/EUR/JPN and install using BBM title manager
To downgrade first download 9.2.0-20 USA/EUR/JPN for the old 3ds. Once done put all the cia files in the folder named "updates" that is in the file you download from me. Once all the cia files are in the folder copy all the files to the root of the sd card of the o3ds. Use a cia installer to install sysupdater and run the program. Once loaded click Y to downgrade. Once done emunand should be either 9.0-9.2. Now with a acceptable emunand version we can continue
System Transfer
Once both n3ds and o3ds have acceptable firmwares between 9.0 and 9.5 install FreemultiPatcher.cia to emunand. Once installed run it and click start to boot back to the home screen. Make sure you're connected to the internet and goto settings and click system transfer. I know people will not like this part but you MUST do an over the air transfer; it's the only option that keeps emunand intact and doesn't make you restart your device. Yes it will take a while depending on how much stuff you have so just let it run overnight or something. Once complete you should now have everything on your n3ds. If once done the transfer you find yourself in a post transfer loop that it asks you to update emunand simply shut down your wireless router and cancel the transfer. Once you access eshop for the first time everything should automatically finish and appear as transferred. Thanks guza98 for the tip on fixing this
If you run into an error on the new 3ds saying you need to update then you have a downgraded system settings. All you need to do is download the correct cia file, install it and try again
