Tubehax/Ironhax don't work without any reason

Hi ^^

A download 2 week ago Tubehax and Ironhax for playing a US game (Since im french, i have a EUR 3ds)

And evrything is okay, but today when i play, i push home by error and restart my 3ds...and after IronHax doesn't work

I have either crash, or black screen on game or either white screen in Tubehax

So, i try to update to 1.10 but doesn't work

So, i reeinstal all but...same error, black screen on game and i can't change Frimware version (When i select change is in US )

What should i...
