Assuming this NOR reflash worked, the device will STILL boot from the default and original NAND flash.
You can either disable the NAND flash (resulting in a boot from NOR) or also flash the OpenWrt Snapshot NAND image.
To disable the NAND boot you have to boot NAND, SSH to it and edit a file or two to make the disable permanent. (I can give you details if you need them).
