Howto: Install DevMenu and SaveDataFiler to NAND to Survive Formats and SD Card Wipes.
Right now, the main method of installing CIAs is to inject FBI into health and Safety app.
I am going to talk about an alternate to this that may interest some people, especially ones that want to retain the stock Health and Safety app afterward for whatever reason.
This will still need FBI injected into Health and Safety temporarily or another method of installing CIAs like Gateway but afterward will not require either.
The alternative is to install DevMenu and SaveDataFiler to NAND, this has very minimal brick risk as these titles are simply ignored on OFW SysNAND or EmuNAND and will show up only while in CFW. these also will survive System and SD formats also.
I had these installed to SysNAND when I did the downgrade to 2.1 for OTP, on both my N3DS and O3DS and ran into no issues in case people are worried about these apps affecting the downgrade process.
-------------------------------------
Make sure you have a method of installing CIAs before doing this
If you are using a version of DevMenu that installs to the SD Card, Install FBI using DevMenu then uninstall DevMenu from the SD Card via Data Management or FBI
If you have SaveDataFiler installed to the SD Card, ununstall it via Data Management or FBI.
-------------------------------------
first, download the DevApps we will need | Search for "[MEGA] Retail Encrypted DevApps! (Caution. These will install to NAND!)" on that site and it will show just that thread) [exclude the quotes in the search]
A thanks to @Apache Thunder for the files
You will see download links to both an SDK11.4 verson of DevMenu (requires 9.2 and CFW with firmlaunch or an updated CFW SysNAND or EmuNAND)
and an older pack that includes the older DevMenu that works all the way back to 4.x along with other DevApps
-------------------------------------
Decide on which DevMenu you want then grab the RAR that includes SaveDataFiler if you have not done so already.
DO NOT DOWNLOAD the files from this link "[MEGA] DevMenu, SaveDataFiler, and PlayCoinSetter (New Banners!)" on that thread, that links to the regular SD Install versions.
------------------------------------
Now that you have the DevMenu and SafeDataFiler CIAs you want (I used the 3D banner ones myself) , Proceed to install them to NAND destination with FBI.
Now that you have them installed to NAND, reboot into CFW again and they will show up and run.
Now that they are installed on NAND, you can proceed to restore the Health and Safety app back to normal if you want as it is no longer needed.
