I have an old 3ds with A9LH installed + CFW and I did the hacked save file. Then I did the system transfer from my old hacked 3ds to my new 3ds xl. When I was on my new 3ds xl i accessed Fieldrunners and tapped on "scores", then dgtool started running. I then chose "Downgrade FIRM to 10.4. When the downgrade was done, it said it was no errors during installation. I then went into homebrew launcher and 3DSilent. It said my Kernel and FIRM version was 2.51-2, when it should have said 2.50-11. I noticed that it was something wrong with my 3ds when I was going to downgrade to 9.2 using PlaySysUpdater, but it always crashed. Homebrew launcher crashed 90% of the time as well. I would really appriciate if you guys could help me. Thx.
