So... I got my new O3ds today - it was on fw2.x, so I used Project X Zone to up it to 4.4.0-4E, then set about creating my emunand and installing rxtools. Everything has gone fine ...up to now. RxTools is installed and updated to 9.9 with FBI installed, but somehow in between unlinking the nands and upgrading the emunand my sysnand has lost the h&s app so I can't inject FBI to my sysnand. And my backup plan of using Ninjhax has also gone tits-up due to there being no QR code for 4.4.0-4E or 4.5.0-4E (which I updated my sysnand to using Animal Crossing after 4.4 fucked me over). I don't have a Gateway card, but I do have Sky3ds. I also have an Acekard2i (but without having access to FBI or Ninjhax I can't whitelist it on my sysnand). What are my options? Is there anyway to get the h&s app back on my sysnand (the restore h&s option in rxtools gave an error that the h&s tmd backup couldn't be found)? What retail game (EU region) can I use to upgrade (by as little as possible) from 4.5.0-4E that will definitely have a valid QR for Ninjhax? Help definitely appreciated.
