EDIT: More specifically, use 360 flash tool to find the sector of the banned secdata.bin, use it's ECC change bytes and look for a one kb section of random data followed by 15 kb of zeroes and an ECC change byte in there that is one less than from the banned secdata.bin ... this should be the old one that needs to be copied over the current. I'm not very good at explaining this really, it's all there in that thread.

From what I understand you can backup the NAND regardless of kernel... but you can't get the CPU key. Fortunately you don't need to decrypt the NAND to find the locations of the banned and old secdata.bin files.
