Awesome! Thanks a lot, worked like a charm. I am also on 11.2 so must be a issue with that OFW and Luma.
For those who want an exact step by step process:
Download Decrypt9WIP and Universal Inject Generator.
Put the Decrypt9WIP.firm in the luma/payloads folder
Hold start and turn the 3DS on
Choose Decrypt9 and hit A
Go to SystemNAND then into Miscellanous and choose to dump Health & Safety, it will dump it to the root of the SD
Unmount the SD card and insert it in your computer
Unzip Universal Inject Generator and place the hs.app and fbi.cia into the input folder
Click go.bat
Take FBI_inject_with_banner.app and put it onto the root of your SD
Insert the SD card and hit B
Go to Miscellaneous and choose Health & Safety Inject
Input the key combination
Choose your nearly created .app and hit A to inject
Hit start to reboot
FBI is now the Health & Safety app
To revert back just take the original hs.app and inject it as the Health and Safety
I don't get the Insert the SD and hit B part.. what do i need to do? :/ kind of confused on that part. clarify please?
