[Request] Bios Hidden mode unlock for Samsung Galaxybook Ion2 (NT950XDA-X71OW)

Hello I want to unlock hidden features in my samsung galaxy book ion2 bios.

I tried amibcp but it didn’t worked and I also tried uefi tool but I couldn’t understand what is what.

I tried almost 3 month but I could’t do it

so I request here for help

Dumped bios from BACKUP_Tools20h2 (P07RFZ) : sendspace.com/file/jggeki
original bios from samsung (all version) : github.com/guosasipo/NT950XDA-X71OW_UEFI

I want to unlock hidden features in my bios

Thanks for everyone who helps me

Any one have any experience on this?

Ok friend, it’s an AMI Aptio V bios , so we have the Eeprom Write Protection error :

Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.
FPT Operation Failed.

You need to unlock it setting the NVRAM Variables to 0x00 by the RU shell tool , here some example and tutorials :

FPRR VarOffset - 0x683

BIOS Lock VarOffset - 0x17

You’ll find under PchSetup [4570B7F1-ADE8-4943-8DC3-406472842384] GUID

Here there are the RU links and tutorials :

Please make some Bios Menu Tabs screenshots to see your bios menu , pack them and upload here too … then you need to make
an USB Stick FAT32 formatted and following the examples, make a folder into his root and then copying into the efi file …
after unlocked the eeprom , you have to make again a result file to check is all is gone well !
Let me know

Thank you for helping me @BDMaster but when I press UEFI Variables it just stops working just freezes and clock on right side doesn’t move how can I solve it?
