I was fearful of reflashing nand so I commented those lines out, I only meant to reiterate that i used uImage.pci, curious if that could've given me a problem.
Im not sure I understand what you mean by subing /dev/sdX1 for NAND. When in chroot jail, I am running from said /dev/sdX1 which is considered root (but I do understand the "mount -o bind /dev dev/" call prior to entering chroot). Should I change the ##Flash Kernel calls to use /dev/sdX1 instead of /dev/mtd1? It doesn't seem correct.
Also, zeroing the drive would erase my backup. If I were to do this, I would just start from scratch, but that is what I want to avoid.
