Re: IdeaPad 3 14ADA5/15ADA05/17ADA05 Lenovo V14-ADA/V15-ADA Bios

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.
