Hacking nand backup question

[mariobros1]

Will restoring a nand backup bring back channels that I had deleted after making the nand backup?.
I ask because I want to fix the upside down HBC and don't want to possibly lose the HBC forever.
PLZ reply.

I did xzxero's guide and it always says *This channel cannot be run on this console* or something,
Therefore I need to use the dop ios mod http://sites.google.com/site/completesg/other-stuff/fix-hbc

I just wanna know if a nand backup would be able to get back a lost HBC.
