    Ok I extracted and modified the bios like post number 1, good size now. Programming was ok, I tried multiple bios file but always black screen, not a bios issue for me.

    Thank for your time, we can't fix them all

    Info : for this model chip Winbond 25Q64FWSIG 1.8v i used an adapter 1.8v 25xx flash for ch341.
