As many have noted, Dell now has a check in place that refused the downgrade (Bios guard), even though the versions are available from their website. You have to go through a much lengthier process to downgrade the BIOS now.

Hi Andrei, Can't talk for for all the Dell models since there are plenty. Now, in the models I've checked, that happens when the current Bios version you have was release due to a major vulnerability that needed urgent patch. In that case Dell locks the Bios. Therefore, installing lower bios versions is disabled ..... Thanks for the comment!

i have dell 3847 for win8 with bios A08. but i wanted to install win10. some web said later i needed to update the bios to A11 for win10, i didnt know about this until HDD was deleted for win10. so win10 couldnt be installed, because it kept failing. so i reinstalled win 8 and updated the bios to A11 . then win10 still doesnt install. year 2012 i didnt know what UEFI format was. and i called Dell and even dell representatives told me that OS was in a chipset, so after 2 months later, i deleted the OS hoping to learn the installation procedure. there was no OS, DELL was bad. since then i couldnt use dell-windows OS, but i just used the normal windows 8.1, DELL driver update site was difficult, it didnt have a single driver download for model 3847, but all these drivers were spread all over and mixed with different models, 1 or 2 installations in device manager were mission but worked fine, but windows update didnt work well for 3847 in year 2024 when i deleted the HDD for win10

[@lerenzuu]

Hi My IT Workshop, So lately, I just upgraded my BIOS of Dell Vostro 5568 to the latest version. But it turns out not very well. Before I upgraded to the new BIOS, my fingerprint scan device was working normally, nothing is wrong with them. But after I updated the new BIOS (ver 1.12.0 of 23 Jan 2020) the fingerprint scan device stopped working afterwards. Showing me the message when I checked on the user settings, saying that: "We couldn't find a fingerprint scanner compatible with Windows Hello Fingerprint". Now just a quick head up, I tried to fix the issue but there is no problem with it, the driver is working fine, I enabled the user policies and what's not and nothing work. So that leads up to my theory of the BIOS might be the one who caused it. Also, I know the method of downgrade the BIOS via the USB BOOT is a risky move since I did research that a lot of computers/laptops blocked bios downgrade even though I did enable the downgrade in BIOS setting, plus I fear that I might end up bricking BIOS, so I'm here to ask you is it really safe to do it if I do everything correctly like in the video and should I really do it or wait for the next BIOS update? I'm looking forward to hearing your replies, my best regard.

[@MyITWorkshop]

Hello Rennzu, If it is really affecting the functionality of the computer and you're sure the issue is due to the new Bios upgrade you installed some days ago. I'd would say you have 2 options; if this is a known issue, then the manufacturer will release an update........eventually. The other option is to downgrade the Bios to a previous, working, stable version or the one you had before. The 2nd option, as i mentioned in the video, can render your computer unusable, (depending on the model it might be possible to fix if that happened). What I did with a computer on which the Bios upgrade failed, was to check the manufacturer's website looking for a way to recover the Bios on the motherboard. This was a 2012 HP laptop and there was no way to fix because it was too old. The solution for me was to buy a new motherboard, same model and replace it, that worked. In my case the hard drive, ram, cpu were working with no problems, so i did not lose my docs/videos/pictures. If you decide to downgrade the Bios, make a copy/clone your hard drive first just in case. Hope it helps! Thanks for the comment!

[@MyITWorkshop]

hello there, 1) Always aim to install the latest Bios version for your system. I googled your model and this is the link for the Dell website, (re-verify that it's the model you have), scroll down and check for "Bios", that's should be the most recent version: www.dell.com/support/home/en-us/product-support/product/inspiron-15-intel-n5050/drivers I have a video on how to do it from DOS: kzbin.info/www/bejne/aGLZpIakmpKBqrM 2) Bios downgrade, like i mention in the video, it's only advisable if your system is having problems after the upgrade. Bios upgrades provides enhanced features and security updates. 3) I think the reason for the error is because your are trying to install a version of Windows 7 that is not compatible with your system. Try updating the Bios and try again. Hope it helps Thanks for the comment!

[@kalpeshchawda5329]

@@MyITWorkshop many thx for ur comments, Yes that's thr right model link you provided me. Also you are right W7 is not compatible though i m confused as it worked while i loaded W7 ultimate from usb.

For an Alienware M15 R2, would it be possible to downgrade from 1.5.2 to 1.3.1? Please let me know

[@MyITWorkshop]

Hello Dan, I would depend on the update. Manufacturers release Bios update to make the motherboard compatible with new hardware, security updates, stability, etc. Now, there are cases when a new update is release to patch a vulnerability and after the upgrade is installed it CAN'T be downgraded. When you try it may show a message like "Bios blocked due to unsupported downgrade". Dell/HP/Lenovo and the rest do this to prevent users go back to a vulnerable version that can be exploited. Hope it helps Thanks for the comment!

[@hairyMANIFICATION]

@@MyITWorkshop yeah that is clear, my next question, would it be possible to override this?

[@MyITWorkshop]

@@hairyMANIFICATION Hello, Like i said it will depend on the update and manufacturer. In the laptop i saw that, (Dell), once that's done you can't downgrade it.........mmmmm you could change the actual Cmos on the motherboard or find a 3rd party software that will allow the downgrade, but that might be more troublesome than it's worth in my opinion.

Hello, On many models there is log in the Bios itself, maybe there it gives you more info about it. As far as i know there is no way to see what was the previos version of your bios. Another tip comes to mind if this is A dell/hp/lenovo etc, when you look for it in the manufacturers website using the serial number or tag number, you can see the date when the warranty started. With that date in that same page you can look for what Bios version was released around that time. Hope it helpa Thanks for the comment.

Hello Nicky, That's odd, on most Dell computers, (not all), you can access the boot menu pressing F12, there are other options like Esc, F11,. Now, if you don't see the option "boot from usb", either try another USB port on the computer and/or another physical USB drive, it is even better if it is another brand than the one that is not working. The other option could that USB boot legacy is not enabled in the Bios, try looking for something like that and enable it. Hope it helps Thanks for the comment!

[@MyITWorkshop]

Hello Dario, I have to start saying: It is no a good ides to downgrade your Bios version since you are removing features/updates from it and might render your computer unusable. Having said that, Alienware belongs to Dell from many years now. So, I would think they use same Bios/UEFI "software". Therefore, the process should work. However, I so far haven't had the change to do it on an Alienware computer. Hope it helps Thanks for the comment!

@@tanishqmatharu5105 Hello, When that happens means the manufacturer, Dell, has disabled backward downgrade. They do this if there was a vulnerability in the previous Bios version(s) and they fixed it with the latest update. Therefore, in order to prevent users/computers from getting exploited by the vulnerability they make sure that the latest version is UNdowngradable, (does that word exist?). If you are having a problem caused by the new Bios version and can't go back to the previous, you have 2 options: 1) Wait for Dell to release a new Bios version that fixes the current issues. 2) I do not recommend this one much......Try even older Bios version and see if they work.
