Faulty NAND's are extremely unlikely and all cases are results of hardware failure unrelated to A9LH. There's also cases where other bits of hardware not related to the NAND fail, causing issues as well.
Don't do that unless you want to brick.
From Aurora github:
WARNING: the stage1 binaries which can be used with 2.0 are mutually incompatible with the ones usable with 1.x. Using old stage1s with 2.0, or new stage1s with 1.x WILL LEAD TO AN UNRECOVERABLE BRICK. As of now, both delebile's and my own fork of A9LH have been updated for this. DON'T USE pre-made stage payload bins found randomly on the internet (Plailect's guide will be updated for this).
