Thanks! I did compare it, the JFFS partition was not present, the CFE location was the same, so was the NVRAM the linux partition had a different offset if I remember correctly. Didn't save the output as the most important thing IMHO was the JFFS and it wasn't there. I then did a firmware upgrade to the fork, directly from DD-WRT which succeeded!!!

At this point I have done a factory reset to clear NVRAM, it rebooted, went through initial setup as it should and it is now very much functional!!!
I am glad I didn't give up on this one!!!!
Success!!!!
Thanks again for all the help!
