    1. Will I lose my a9lh on the source 3ds?
    2 do I need to transfer the entire sd card content? (Because we all know that takes years to wirelessy transfer and I don't want to do that)

    Thank you :P

    1. No, you'll make a nand.bin backup that you can restore afterwards.
    2. Yes, I'd recommend a USB 3.0 sd reader ;) - took me about an hour to copy a 64gb sd with USB 2.0 speeds

    So if I don't make a back up before I'll lose it and I'll be stuck on the latest version?

    And also I deleted everything to make it quicker so I only have about 2 gigs on my sd card

    No. If you dont make a backup you could always re-inject FBI into the Health & safety app (because you'll already have hourglass9) but it would be just a waste of time when you could easily make a backup then restore it

    Ill give you a quick rundown.

    • make nand.bin backup on source 3ds.
    • make backup of source 3ds sd card
    • inject dsiware hack & follow guide as usual
    • if prompted pick 'PC transfer'
    • take source sd card and put into target 3ds
    • continue guide as usual
    When finished just restore the source sd card backup you made earlier and restore your source nand.bin

    Both should be hacked now & then just wait a week to transfer back (so both will have working NNID's)

    Can't exactly do that since it's a 2ds to a new 3ds

    Thank you so much for the other things! this info really helps

    I'd use a microSD to SD adapter then if possible.
