Bios Mods -The Best BIOS Update and Modification Source

Hi,

I flashed the BIOS of my Samsung NP532U3C-A01 for the most recent P13ABH (P09ABH at start, and I can't find the file to rollback). Unfortunately, this new BIOS is highly restrictive. I can't disable Secure Boot (I'm a GNU/Linux user... bad luck, and I need to modify ACPI for eGPU purpose) and downgrade of BIOS is not possible (ERROR 182 - BIOS image is equal or older than ROM!) with no options available in the actual BIOS to fix the problem (only tried with SFlash64 with old P06ABH BIOS, the only one I actually found).

I'm here to ask if someone's magic can modify the P13ABH BIOS to fix my problems please (Secure Boot / Flashing the BIOS). I uploaded the file that you'll find here or in attachment with this post :

• P13ABH.exe
  
• P13ABH.cap
  

Thanks a lot !

With no answer on two weeks, did I've to understand that it's not possible ? :/

It seems that I was on the wrong section. My bad and sorry for that.
I published a new post on the Phoenix UEFI section.
