1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode. Let it run for 2minutes, it will restart several times with no display.

Dell latitude 5420
Can someone help me with a clean file?
I dont get though why this file is so small.
Chip is Winbond 25R256JVEN. SHould this not be 32mb or so?
It has been verified and read twice .
It was read however on the board with insulated wires soldered to the programmer

edit..ok here is what I believe is the correct file..
I used asprogrammer this time.

It should be 32MB. The dump from this chip must be 32MB not 8MB, so you doing something wrong for sure. Did you choose the right chip within the programmer software?

You're welcome. Be careful with the programming of the dump back to the chip, use verification. I suppose you know how to proceed after the first boot, if not read some previous posts, for example post #307.
