    Well you can certainly try the USB thing, if you get an 2 options Recover BIOS and Reset CMOS to defaults then I feel recovery trick can be done to re-flash older BIOS. Bypassing it might cause it to brick, so grab a good copy of full ROM file using HW flasher.

    I did not follow c69k's guide as I haven't seen it. I have been doing tech work for 20 years though so I'm not sure what he would have done differently. I have a dedicated 256mb (yes, MB) usb flash drive that is formatted in FAT16 for cases like that. I do have an EPROM programmer but I didn't want to go that route (no longer have the XPS).

    Trust me, I've tried the recovery trick at least 10 times and it does NOT work.

    Try these steps:
    It is possible to downgrade even after you get the 'Bios protected message'.

    STEP 1: Making flashable Dell Bios file

    1. Go to This PC/view/ and check File name extensions
    2. Then rename Alienware_13R3_SKL1.2.3_KBL1.2.3.EXE to BIOS_IMG.EXE (in your case rename any Alienware 13 r3 BIOS to BIOS_IMG.EXE)
    3. Place the BIOS_IMG.EXE to the root of your c: drive
    4. Open Commamd prompt/Run as Administrator
    5. Write cd c:/ this will get you to the root of your c: drive
    6. Write command BIOS_IMG.EXE /writehdrfile
    7. Then rename the created file BIOS_IMG.HDR to BIOS_IMG.rcv (please note rcv is NOT capital letters)

    STEP 2: Making DELL approved bootable USB stick

    Skip steps 7 to 10.

    STEP 3: Making USB stick final for flashing

    Copy BIOS_IMG.rcv to usb stick, so there will be 3 files in total:

    DELLBIO.BIN and DELLRMK.BIN and BIOS_IMG.rcv

    STEP 4: Flashing

    1. Put USB stick to left hand USB port
    2. Turn your laptop OFF
    3. After its TURNED OFF Press and Hold CTRL+ESC and do not release
    4. Press START button (do not release CTRL+ESC)
    5. Wait Till you get to BIOS RECOVERY SCREEN (now release CTRL+ESC)
    6. FLASH BIOS

    If it works for you please make it a sticky post.

    With major changes due Intel's flaws - MEI/EC changes expect rollback to old will be *almost* impossible. Dell is the bell sheep in this.

    Its better than not having anything. Insyde H20 don't even have a standard USB recovery procedure. Its heavily locked down.

    MEI won't downgrade rather BIOS,RAID/AHCI/NVMe OROM,uCode,GOP will be downgraded to older BIOS release if Dell changed them in new versions. If MEI is poof, then only method is to use HW flasher and win-raid's Stock MEI FW w/o DATA Init part to recover your whole BIOS.

    That's no different than what I've done. It doesn't work.

    BTW: "Since 1.4.1 has Boot Guard updated, once updating to 1.4.1 or later BIOS, system can't roll back to the BIOS earlier than 1.4.1."

    So your XPS doesn't TURN ON at all? If so, that's sad. Then Dell must update their BIOS recovery manual. There's a way but I haven't tested it and never done it myself, i.e, Capsule based FW patching with the help of UWD framework found at Windows Update, it might bypass security restriction and boot into recovery shell to flash older image. To which degree it works I don't know. As for getting proper devid you can use Device Manager > System Firmware and check its properties and paste the same at win update catalog website.
    I haven't come across it on my client's machine. Its just a possibility.
