Hacking New 3DS XL MHG Hanging

[xstationbr]

New 3DS XL MHG Hangs when, exit from configurations to Home menu, or when need to reboot 3ds, like after an System Update.
This system is with A9LH instaled and updated.
When i do an System Downgrade to Ver. 2.1 all works fine, no one error like this happens.
Downgrades to 9.2 or anyone version same problems, only in the 2.1 i dont had problems.
I think this maybe be any module or file on sysnand cant allow change transistions from home menu to configurations or reboot, some time these happens when i exit from any 3ds game or twl (nds rom emulation without flashcard).

Sorry my bad bad english, but i cant correct by now, im on street and i dont speak english, but i cant correct ortography in this moment.

Thanks for all yours help.
