Unlocking all settings in the Insyde/H2O BIOS

Hello,

I am interested in unlocking all settings in the BIOS of a notebook called: Medion Erazer P60. The BIOS is Insyde H2O, and I have researched a bit about this and found out that with an application called H2OUVE, it is possible to change UEFI variables.

I have tried a lot of methods to unlock my BIOS settings but none have worked. I have tried using GRUB Shell commands, which results in an error that means: “hard disabled the show all option with an always false compare in the BIOS”. I also tried using the “non-official” H2OUVE application, which does not export any saved changes at all, probably because it is not an official application by QT.

Here is the link to download the BIOS (Update) for my notebook:

I have contacted Medion support and they just said: “we cannot unlock the BIOS because it is locked”.

I am totally exhausted from trying unlock all the settings in the BIOS.

Any help is appreciated!
