Root Nand backup or boot img

[Biotic]

I need either a nand backup or the boot img of the enlighten running a firmware of less than V4? I believe. Im not sure how many firmware updates this device had, so you guys will have to fill me in.
My enlighten came with firmware version VS700ZV5
I need the earlier kernel used on this device, again before V4 (if such thing?)

I am working on a root method for you guys and a custom rom, once i get there ofcourse.
