Use Panasonic SD card formatter (just google it) and give it a try then (try only placing the Wood files on first).
Another thing to try is running the update patch first on the working kernel and running the specific www.r4-pro.com version of Wood (only at 1.30 but it may be different from the other versions of Wood out there).
