Thanks for your feedback. Do you know which tool to use to flash an old version of Bios? Current version is EGCN34WW and official Lenovo tool does not allow any Bios downgrade.

Thank you very much for your replies. Hopefully, I'll write for the last time on this issue, hoping to fix it with your guidance.
- I've extracted the content of EGCN33WW and modified a few settings in the configuration file named platform
- With H2OFFT-W app also available in the extracted content, I successfully downgraded the BIOS to a previous version but the BIOS password is still there and I cannot get into Bios to modify any settings.
Which settings I should change in the configuration file (attached to this post as platform.rar) so that it would reset/delete the Bios system password, which I set myself but forgot?
Kind Regards,
