What's the simplest way to hack?

Hi all, i have a O3DS XL in 10.1.0-27U andi used to use Tubehax to boot HBL. I didn't got Ironfall before N patched it. My 3DS was for sometime back in my bag, now i discover Tubehax is gone.
What's the easyest way for me to boot HBL again? I want to install homemenuhax 2.5.
I think this question has been answered in some (many) threads but i have a very limited internet time to search.
If it helps, i have OOT3D phisical.
Thanks.
