As in any flashing to the wii nand it’s dangerous but you have to decide
Wither the benefit out ways the dangers.
What I will say is out of the thousands that have flashed to boot2 probably 99.5 %
Of them never have a problem, BUT there is always a chance it could go wrong that 0.5 %
I remember when I installed bootmii, and yes I was pooin’ my pants
But I took the chance and well there you go. Life is all about risks
