Went back to the old Dell 7577 and updated everything without noticing that the bios update destroyed undervolting. Using: -Your tutorial to generate new bios -(as of current, the latest) 1.12.1 bios & 1.9.3 legacy bios -install -set settings to 'bios default' rather than 'factory settings' as it doesn't seem to exist -Disabling UEFI Capsule Firmware Updates & enabling bios downgrade once again Throttlestop ha once again saved my laptop! Thankyou somuch and you saved my entire system. Keep up the good work.
You are an absolute legend. I used your help to compile a 1.13.0 bios exe disguised as 1.14.0 to downgrade. Then I wanted to downgrade to 1.8.0 cuz i saw it had better performance so I tried just launching the bios exe but it was blocked, so I used the same method to make ANOTHER exe, this time 1.8.0 disguised as 1.13.0. It worked too. Now my games stutter wayyyy less than they did on 1.14.0. Thank you so much. I'll install a different nvidia driver to see the performance as well.
Thanks for sharing this. I used this technique to downgrade the BIOS on a Dell Precision 7720 that I had purchased which has the latest cancer firmware 1.35.0 (March 11, 2024). I was able to exorcise this gimped firmware filth and dowgrade to BIOS 1.15.1 (July 2, 2019) and regain overclocking and voltage control. The boost in performance in the ThrottleStop benchmark was nothing short of phenomenal.
Hai... I was about to do this downgrade on my dell 7567 laptop... But i didn't find 1.11 & 1.9.3 versions in the dell support website. Can i do this process with 1.13.1 & 1.10 versions ?... Please reply whether it works or not. Thank you !
Works perfect on my 7577. It was with BIOS 1.17. Been in the bios settings uncheck UEFI and then checked BIOS Downgrade. Then I logon into windows and did the steps. It took me 10 minutes without any problems. Now i can use trottlestop. THANK YOU VERY MUCH! Edit: after several test directly from the benchmark that Shadow of the Tomb Rider have I hit 72C temperature on ultra settings with 38-45 Throttlestop settings: Disabled Turbo CPU offset 130.9 CPU Cache 130.9
I don't normally comment on youtube but your video ABSOLUTELY saved my 7577. I was getting so frustrated and you laid out the work in such a simple and clear way. I appreciate you good sir! Edit: downgraded from 1.14 to 1.9.3, used throttlestop, stable -100mw with a 20 degree drop while gaming :D
september 2024 downgrade from 1.17.0 to 1.9.3 successfully and this still works. Something to note is that you should untick immediatly "uefi capsule firmware update" in bios after dowgrading before the system boot to windows main screen otherwise drowgrade will be reset.
Still works 09/21 using the latest 1.13.0 file & the suggested 1.9.3 file. I didn't have factory settings option on the last step so I chose default, which worked. I also switched off the BIOS UEFI update under security. Back to cooler temps and no thermal throttling. Thanks!

Doesnt seem to work with G3 3779, trying to downgrade from 1.25.0 to 1.11.0 and i get failed to update error "Intel ME" gets in the way and back to this crap bios again, searched all over and no one has any info on my laptop model. Nevermind that i managed to get it back to 1.11.0!!! and throttle stop allows uv again. So the steps i had to take: 1 Disable BIOS UFFI (this thin kept reseting my back to my latest BIOS) 2 Did secquencal downgrade instead of jumping straight to 1.11.0 (going from 1.25 to 1.24 skipped few version that dint block me to 1.13) 3 Ran custom bios ive made before (1.25.0 made into 1.11.0) 4 I still got some "Intel ME errors" fail but they dont seem to matter as dell software offered to update my bios and it finally showed my bios at 1.11.0 So thank you so much! i will share your turtorial in reddit dell section so other suffering like me could go back to undervolting again.
Does this method work for dell precision m6400.. By changing versions of bios according to my bios need.... Plus i didn't see downgrade option on my pc in bios setting...??if anyone know please guide me
I'm stuck at the very last part! I don't have the option to Factory reset my bios. Only "Bios default, last known good settings and custom user settings" 🧐🧐 EDIT: Did Bios Default and works anyway! Thanks man you are a damn saviour! Its embarassing for DELL this bloody mess!
Hello! I downgraded my bios just like your tutorial, however, undervolting is still greyed out. Not sure what to do because the downgrade actually worked.
Hai... I was about to do this downgrade on my dell 7567 laptop... But i didn't find 1.11 & 1.9.3 versions in the dell support website. Can i do this process with 1.13.1 & 1.10 versions ?... Please reply whether it works or not. Thank you !
Is the last step necessary? Aka the "restore settings" step? I only want to downgrade cuz I've been getting some issues with the latest one. To my knowledge flashing bios automatically resets bios to it's default settings. So shall I leave it like this or do I still need to do the last step in video and restore settings? Thanks
For me, it worked after I did it. I am only showing what worked for me and hoping that it would work for people as well. You can try and see if it works without the last step.
also all must know in bios there is a option in security tab "UEFI firmware capsule" and this must be off because this is automatic update bios from Windows Update or Linux...and windows will update and all over again :)
Is there any specific setting or care we should take to not have a future unwanted update fuck this changes? Like not updating the bios anymore I guess or else?
Hey man, just reply please whenever you see my comment, I followed every step and when it comes to cmd after pressing enter it says no python was found.. I'm just stuck here
Suppose if dell release 1.13 or any new bios update can i install it without any problems after i install bios with the steps u mentioned above?like in future can i install new bios setup without any problems? P.S i have sucessfully done the above steps and its good and can u suggest the values for throttle stop and Intel xtu
Thx for this. My battery died a couple of months ago, isn't there a way I can complete the last step not having the battery plugged in? A warning pops up and won't let me run the __output.exe
