Hello there,

I want to mod the InsydeH2O BIOS on this Lenovo Ideapad 320-17IKB, type 80XM and already dumped the BIOS, edited it to have a new SLIC table. However, when flashing, it gives the error ‘Invalid Firmware Image!’ after a reboot to flash the modded BIOS. Can anyone help me out? I would also like to change/display the Advanced settings (menu).

BIOS file: https://download.lenovo.com/consumer/mobiles/4wcn47ww.exe

Advanced settings (menu) → use unlocker windows.zip (after reboot and check) ( [Tool] Lenovo (H2O) Bios Unlocker and Locker) or InsydeH2O BIOS Modding Problems - #21 by acid96

I didn’t close this it seems but I discovered this like 1 year ago. Since then I had bricked my laptop once by changing some setting but was able to recover, at least I changed the boot logo!
