Hacking asking about memchuckhax

After I saw a lot of bricks about downgrading from 10.3... I would like to know why there is not a tool that allow you to backup yor NAND before to try to downgrade... has this exploit the access to the kernel that allow it to reads the nand and backup this? and sorry for my english

right now we don't have it, the only possible (public) way to backup your nand on virgin 10.3 is via hardmod

If you already had access to backup your NAND there would be no reason to downgrade.

There is currently no arm9 access on 10.3, so no one on that firm can backup through software. You can always hardmod and backup first, then downgrade which is a really good idea.
