    I have a 3ds that is 4.4 and I was wondering if I should look into backing up the firmware. I has seen the only way to downgrade is through a backup. Should I look into this? Is it easy to revert in case of accidental updates?

    And also is the backup 3ds specific, or could I downgrade a friends with my backup?

    Is it easy? Depends on if you have an XL or normal 3DS and if you can solder. The 3 points you need to solder on the XL are all on the same side, normal 3DS consoles have 2 on one side and 1 on the other unless you desolder the game cartridge reader.

    I said BACKING UP the NAND is risk free and easy. Flashing the backup is incredibly dangerous and not easy at all! Unless you have experience soldering, I would just making backups for some future way to flash over the realNAND. Gateway said they were working on something.

    So backing up is easy but to actually revert the back up requires soldering or is that to flash a newer console?

    Reverting firmware on any 3DS console requires soldering.

    Reverting to the backup requires soldering, which is better than simply not being able to revert at all. Flashing the newer versions is unfortunately too easy lol.

    I have backed up my NAND 4x with the R4i Gold 3DS and I'm using hasher to create md5/crc32/sha1 and they are all different on all 4 of the NAND.BIN how do I know which one is the good one?

    they are all most likely fine, everytime you power on the console it makes a change to the NAND so you will never get 2 identical dumps

    If you powered off your 3DS between the dumps it'll change...
    When I had a 6.2 3DS with hardware mod, dumping two times in a row game me same md5, but after a reboot, even without changing anything, nexts backups had a different md5.

    Thanks much for the replies. I just wanted to make sure I have a good NAND backup.
