Beginner on TL866 needs some help

[orgamisho]

Hello all!
I am repairing  a device and to do so I have to reprogram the nand flash in it. I've successfuly read the nand and I found the data I need to change before programming it back to the nand but it seem that the data is grayed out and I can not change the cells.
I am using TL866ii PLUS with xgpro v10.75 software

Thank you in advance!

You need to edit the data with a hex editor.
I usually use Notepad++ with the hex editor plugin.

Unfortunately Notepad++ coould not open the file as it is doo big, but tried with a different hex editor and it worked!
Thank you!
