Hook up your Jtag to your computer.       Hit start>run> then type in "cmd.exe"       Change the directory to the folder nandpro is in.(for example, if my nandpro was in a folder named "nand" on my desktop, then it would be 2 commands: cd desktop  then  cd nand).
       Then type in "nandpro <device>: -r16 nand1.bin" where it says "device", you would put lpt or usb, depending on what you are using. This will extract your original image        then type in "nandpro <device>: -r16 rawkv.bin 1 1" this will extract your Kv. Now take your XBR3 image, put it in your nandpro folder, and rename it to "xbr.bin". then in command prompt type "nandpro rawkv.bin: -w16 xbr.bin" this injects your kv into xbr. Now type in "nandpro <device>: -e16 0 400" this will erase your nand on the board. DO THIS AFTER YOU HAVE A WORKING BACKUP OF YOUR NAND. now type nandpro <device>: -w16 xbr.bin" and youre done!

Can someone post a tutorial on how to put XBR3 on your Jtag?

Thanks..

Why not just do the new freeboot v0.32 o.o. It doesn't require cygnos anymore if you didn't know.
