I'd dump it again and make sure that your fifth dump is the same as 1 and 4 just to be sure.

You may want to check your wiring, because if you're getting different reads 50% of the time, there's a good chance you won't get 100% good data written to your nand when you try to write with your current setup.

You have 2 matching dumps ! Perfekt, just continue. It does not really matter witch dump you take, since all you really need is you kv and config.

i dumped it again 5th matches 4 and 1st, i ran the rawkv and config commands, reflashed it and i get a e79 error, im about to flash back to the original, to see if it makes it go back to normal.
each time i dumped them i got error 250 block 27b  and  2bf,
which wire is the ground i will check it and resolder it to make sure it is good?
should i just try reflashing it with the modified one to see if it just did it bad the one time?

If you  get an error  reading 250 block 27b and 2bf you most likely have bad blocks on your nand. Do get this error when writing to nand ?

alright i reflashed it and it is back to the e79 error,

i found this  http://forums.xbox-scene.com/index.php?showtopic=699571
it says to check the jtag wires with a multimeter, should i just retry soldering all the points on the jtaging parts.

I would remap the two bad blocks and then flash again.

You need to remap the bad blocks. What kind of nand do you have ? 16 MB ...

use flashtool v.94 to verify the positions of your bad blocks. Then you can use bad block mover tool, or remap them with nandpro.
