Thanks for the clarification Laffinorse, it sure helped.
You said "All that means, Next Step use the editor along with windows calc set to scientific mode Hex ticked"! I understand this to mean that the calculator is used as an aid to determine the revised value that is to be entered in the appropriate location on the Hex editor. Is this correct?
I don't seem to have any difficulty comprehending the Hex String step but the Hex Address step still eludes me.
I don't see what I'm expecting to see when I do the hex address step. In the "Go To" box, I enter a hex address (let's say 0X47). The cursor jumps to some location however, what's there doesn't look like what other posters describe (either before or after it's edited).
For instance, with an original LNFA1091.ESU; doing step "Go To 0X47", the blinking cursor jumps to the right of 98 in the value "9800" on line 0000003C. With LNFA1098.ES3; the cursor jumps to right of 06 in the value "06B0" on line 0000003C. In another post, (referring to I believe, 1091) it says "At 0X47, the value there is B0"! I don't see "B0" or "0X47" anywhere on the line where the cursor lands.
This puzzles me. Am I missing some thing? Either those posts are working with a different firmware, or I'm still not following the logic. Please help me to better understand the hex address step.
