Ok so I have all my files for my old Jtag, but i only have a picture of my fusesets to get my CPU key, and theres a fresh Kv that I need to get out of my flashdmp.bin
But whenever I put in what I read as my CPU key it wont work, ive tried for a while changing the CPU key and it wont work.

I know its the cpu key as when i go to make a freeboot image with my original nand (worked when my Jtag was working) It fails saying the CPU key does not match the dump.

So what im asking is does any1 know how I could improve the accuracy of the read I get from the picture (good quality)
Or is there a way to get your CPU key from your freeboot image? (Doubt it)

You can't get the cpu key from the image but make sure ur using 3-4 for line 1 and 5-6 for the second line and put it together also somtimes a "C" will look like a "E" and "D" like "0" so double check, if you want send me the pic and i'll have a look for you (don't worry its useless without the nand dump or kv) if you want ok.
