I just installed arm9loaderhax on my friend's 3DS, now I'm trying to update it back to 11.2 so he can enjoy Luma CFW... however, updating through System Settings goes about 3/4 of the way and then fails with an unknown error. So then I tried flashing the NANDmin.bin backup that Decrypt9 makes you backup before you flash the CTR Transfer, but Decrypt9 says that it is corrupted/from another 3DS and I'm 100% sure that it's from his 3DS. Then I was going to inject FBI over H&S, install sysUpdater but decrypt9 refused to find FBI (even though it was in files9 folder) so I dumped hs.app to see what was wrong, and hs.app it dumped it to files9, and when I go into the inject selection screen in D9, it only allows me to inject the hs.app that I just dumped. So I thought my firmware was corrupted, so I used a cart update to 4.5 with Animal Crossing, it suceeded to uupdate to 4.5, however, it still errors when trying to update through System Settings. I still can't inject FBI. So what are my options? I tried downloading Garfield's Kart racing to update to 9.5 so I could at least use ninjihax to re update, but my trash 3DS (sky3DS blue button) won't fricking recognize the rom Thanks for your help in advance.
