Also! Here is a forum post you might find useful before proceeding with the update. I got lucky like the users in the post and the update did not brick my laptop.

Thank you, the instructions provided in the link worked perfectly. Was able to update the bios of my ThinkStation P700.
Glad it helped!
InstaBlaster.
the only resource online that worked to update my bios on my t450s. Thank you
thank you. I used your video as a tutorial
That beginning was really funny! xD Wahaha Thanks!
Glad you liked it!
I just did this with both of my T420. Tomorrow I will upgrade my Linux Laptop to 16GB RAM and the remaining bar will go into the Windows laptop so it will have) 8GB. Sounds strange, but I only use Windows occasionally.
CPU upgrade, well wait and see...
Nice
I found that after waiting only two hours, I was able to stop the update utility and get my T420 back into action.
Nice
Intro was funny I give you that frank

I did the exactly same for my t450s but, when i choose my flash drive from boot menu, it just simply back to boot device menu... didn't show the anything...am i doing something wrong?? do i have to fromat the drive using Fat32 or ntfs like that???m
Yeah sounds like it's not being treated as a bootable device. Try re-formatting the drive and burning the image again.
@@Frankiscool ooh i forgot to mention... it worked, when i changed the boot option to UEFI and used "RUFUS" to burn the .img file to my flashdrive. that "DD" method doesn't work for some device, i read it somewhere, they mentioned to used "RUFUS" for that purpose.
@@sagarkumarbala3837 Glad to hear that you were able to get it resolved.
Hey Dude, I found your video by accident.
I flashed an unofficial bios version onto my T420, now im getting 2x5 short beeps on startup.
The problem is that I wanted to flash the old bios back onto it with the Lenovo Tool but it cant find the BIOS directory and now im stuck.
I hope that u can help me :D
T. Sounds like you might have bricked your BIOS. I found: ruclips.net/video/LxwXdIJwrX8/видео.html, in the description it has a website where you can find bin files for different laptop models, I’ve never used the site but maybe it’ll point ya to a direction.
I didnt brick my device, I can still boot to windows, so I really dont know where the problem is
T. Ah, I was under the impression that you couldn’t fully boot up. How exactly did you flash your BIOS? Why not reflash again using an official version?
Do you have discord?
@@Sobthom I do not, sorry. :/ (also I just saw this comment)
I got an error..bios directory not found after pressing "2. Update system program"
Sorry, I didn’t run into that error. Did a quick search and it seems some people on the ThinkPad forums have. Maybe your BIOS was already flashed?

I bought i7 2670qm but the laptop wont boot only flashing light of the power button I hope you can help

@@Frankiscool Yes someone told me best version of bios for this is 1.46 I downgraded to 1.46 and still nothing I even tried replacing the ram and placing in it on the other slot still nothing.I recorded a video.

Not starting at all? Do you get the BIOS screen?
@@Frankiscool thanx for te reply managed to start and its working fit n fine no issues atll
@@sunny1to3 That is great to hear! Mind sharing what the issue was and fix?
How did the cpu upgrade work out? Any compatibility issues after the bios update?
I have had no issues with it. :)
Can you update bios without operating system
Yes as long as you have the image burned on your USB stick.
are there any rules for using multiple displays?
Not sure I understand.
What if I wanted to do it from Windows 10?
I believe by default you can just use the Windows download they have, you don't need to do anything fancy.
¿Dónde puedo encontrar la actualización para la misma BIOS pero para Windows 10?
Where can I find the update for the same BIOS but for Windows 10?
pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t420/downloads/driver-list/component?name=BIOS%2FUEFI
Downloads section.
@@Frankiscool The problem is that it is not for Windows 10
Alejandro Gomez in the video I downloaded the one for Windows 8 but I’m running Linux. You need to find a way to extract the bin file from the download and burn it on a USB, like you saw on the video.
@@Frankiscool I understand, thank you
Alejandro Gomez Good luck! Buena Suerte 🍀
My laptop don't have OS any solution to update bios before installing OS?
You need a way to burn it on the USB drive. I would just install an OS, then do the BIOS upgrade. At least, that’s what I did.
Is it required an OS to update BIOS?
No, if you already have the bootable USB with the BIOS update then you can do it.
I've got a problem on my thinkpad, It wont flash into anything since I installed Linux in it, idk if its a bios issue but I'd like to know if you can help me with that
bruh what. Download the latest update from the ThinkPad, burn it to your USB stick, and then go brrrrrr.
Hope you got it sorted out
is this works on t430?
Process should be the same, just make sure you download the right file for your version.
What's wrong with your tutorial or video is that you didn't go into any real detail in terms of copying the script and replacing it within the parameters. It doesn't tell you a whole lot or enough to confidently be able to do anything after watching it. You should do another thorough step by step tutorial on exactly how to update the Bios.
It is not a tutorial. Also, the article referenced was shared in the description. 🎉
Knowing what you already know, you should now do a comprehensive tutorial on the topic. That's my opinion.
