    I followed the instructions in the OP to downgrade the bios on my 15 r2 from 1.11.0 to 1.8.0 just to restore the beloved undervolting feature, went and formatted my flash drive using the dell diagnostic tool, double checked everything including the files on the flash drive, all good. after entering the recovery menu by pressing ctrl + esc the bios couldn't find any external device no matter which USB port i plug it in, I tried reformatting the flash drive to FAT filesystem and add the files on it manually but without any luck, after wasting some time searching for a solution i managed to get it done by adding the extracted bios image to the EFI partition of the c:\ drive, the exact path and folder of the image files must be: (your efi partition letter):\EFI\Dell\Bios\Recovery\ (in case yours doesn't exist), by default the Recovery folder must contain 3 files
    *(BIOS_CUR.RCV) + (BIOS_PRE.RCV) + (BIOS_BIR.RCV)* as the name tells one of them is the current bios image and the other one is the pre version of it (dunno what BIR stands for), so i made 3 copies of the BIOS_IMG.RCV and named them according to the names above*, went and copied them to the recovery folder, restarted the pc to bios recovery, selected the flash bios option, the reflashing went smoothly, machine rebooted normally, checked for the undervolt and it's there, perfect!

    PS: updating or downgrading bios must be done in order (means you should flash the version that is right below the one on your machine) just to avoid any corrupted bios drama whatsoever.

    regards.

    Maybe, but at the time the BIOS was new and there was no one reporting issues as of yet. I wasn't going to try again and risk something even worse if it turned out the machine didn't like going back from 1.13. I think it's safe to say most people are avoiding 1.13 like a plague though, it's horrible for CPU performance.

    So, I seem to be having trouble trying to downgrade my m15 R1's BIOS using this method. Everytime I hold Crtl + ESC, it goes straight to Windows, and selecting the USB drive manually doesn't work because it "Can't load kernel file". Am I doing something wrong?
    Edit: Looks like I don't need this as the BIOS I wanted to downgrade went through fine the normal way.

    Hi all, I have an alienware M15 i7 8750h rtx 2060.
    Am stuck in 2.6.0 bios unfortunately.
    Tried the method of copying the file on EFI partition 3times etc. Didn't work.
    Tried the with bootable usb after doing all the steps mentioned, it won't access to bios recovery (I keep holding esc+ctrl) but nothing..
    I am grateful if anyone would help with this.. It's burning when it has some demanding tasks
