There it is.
I've tried close to 40 modified files and non of them worked.
The only thing that actually worked was a file from the Latitude 7400 model. Password was gone and Computrace is OFF,
But then i couldn't modify the 7400 BIOS to match this machine....:fou: (fou):fou: (fou)

I get the same result with every file. Password lock and Computrace...Everything just like original.
i think you not Programming right it.
You may need to record the programming process. I can ask it later to prove that you programmed correctly.

I'll program the last file you provided me, and I'll read the chip after I'm done programming, then I'll do comparison for both files. One you give me and the chip after programming. Good?
