Force downgrade Alienware Area-51m Bios (or any alienware) to locked lower versions

Well I am on the latest BIOS and the 87 slider works fine. After the latest update of Alienware command center I did paste in the profiles.zip from another thread.


I do find that gaming on "Full Fans" works great.

 

So very fortunately for me someone on Reddit forwarded me to this thread. i have just bought an alienware M15 R1 with an i7 9750h and an rtx 2070 MaxQ. i recieved the laptop with the bios already in 2.4.1 brand new out of the box. thankfully after reading a previous comment on here of the guy getting to from from 2.5 to 2.0.1 on his M17 R1 which runs the same exact same BIOS as the M15 i decided to take my chance at it. i upgraded myself form 2.4.1 to 2.5 so i could be running the same software as the person with the M17 then followed the steps from OP and Voila i am magically now on 2.0.1 and have access to undervolting. undervolted my cpu to -160 this far and brought my heaven extreme benchmark from throttling all 6 cores to all cores capping out no higher than 83 for a 20 minute test. tomorrow i will be replacing the thermal paste with kryptonaught to try and increase performance even further. thank you guys so much for the immense amount of info and im happy that i can confirm for you guys that this has worked for me. also note though in OP's origanal instructions. on dells website in the bios download options. they already had and RCV file available to downlaod so i used that one instead of using the CMD to make my own from an HDR and it worked just fine. thank you again

 

Kriptonaugh, that's new

Seriously tho, don't use Kryonaut. Temps will be good for a couple of days and them they will get worse.

Gelid Extreme, Phobya (though erosive to heatsink and die) I would personally recommend (non conductive)

If you want liquid metal you can use Conductunaut / Liquid Metal Extreme and one more Chinese liquid metal (I forgot the name )

bear in mind this liquid metal eats away a layer of copper forming a black mark.

 

Another way to do this (tested on my AW 15 R4), the way to downgrade is:
1) Place the .RCV 1.11.0 BIOS file on the USB drive
2) Rename to BIOS_IMG.RCV
3) Insert into any USB port
4) Turn off your pc
5) Hold CTRL + ESC, press the power button, hold CTRL + ESC until the BIOS update screen opens. (Do nothing on the menu)
6) Remove the USB drive from the computer and replace the BIOS_IMG.RCV file with the previous BIOS with the same name. (ex: 1.8.1.crv for BIOS_IMG.RCV) - On another PC, ok?
7) Insert the USB drive again into the same USB port.
8) Follow the process to update the BIOS.

In my case, undervolt is not working back again, but the BIOS is again 1.8.1 instead 1.11.1.

If anyone makes progress, share it! Here the temperature without undervolt is complicated!

 

This tutorial Works!!!!

Just change the BIOS_PRE.RCV with the older bios in EFI partition
Restart in BIOS RECOVERY and make the ROLLBACK BIOS.

 

@S.K Do you mind if I copy this into the /r/Alienware FAQ? Or at least put a link to it, with credit to you of course.

 

Nope, why would I mind? The main purpose of this info was to help the community out and nothing more. Feel free to copy-paste all of it.

 

Hey can I ask a favor? You followed the guide above where it mentions going to EFI > Dell > Etc to get to where the BIOS.PRE file is located. Can you make me a list or show me a screenshot of the files in that directory?

I had a crash on my Alienware provided hard drive and that means I lost the recovery files and the Dell EFI folder so I'm going to try and create each directory manually and try to find the files that need to go in there to roll back my bios cause right now every USB version I connect it tells me I have an invalid header image. If you don't mind helping I would appreciate it!

 

This is such a great thread. It's nice to see all the involvement. Kudos @S.K
