17. Copy `<date>_<serialnumber>_sysnand_##.bin`, `<date>_<serialnumber>_sysnand_##.bin.sha`, and `essential.exefs` from the `/gm9/out/` folder on your SD card to a safe location on your computer
    - Copy these backups to multiple locations (such as online file storage, an external hard drive, etc.)
    - These backups will save you from a brick and/or help you recover files from the NAND image if anything goes wrong in the future
18. Delete `<date>_<serialnumber>_sysnand_##.bin` and `<date>_<serialnumber>_sysnand_##.bin.sha` from the `/gm9/out/` folder on your SD card after copying it
    - The other backup files are negligible in size and may be kept on your SD card for ease of access
19. Reinsert your SD card into your console
