Updating BIOS on a Lenovo laptop - running into an immediate problem at the first step with innoextract

Ok booting again

I downloaded KUCN37WW and copy it over to the HBCD and booted from USB. Selected the KUCN37WW.exe and extracted it to its own directory. Found the exe within and selected it and it open no issues, couldn’t try the flash as my computer is a different model.

Strange. I didn’t try it on the hirens boot disc. I just looked at the file and it say’s .exe but i guess i was right that it was a compressed file.

Edit: The OP may have made progress? :thinking:

Testing right now - I need to connect to the Internet and redownload it each time

Same error even after enabling back flash

That’s the exact version I am downloading actually. kucn37ww.exe. Weird how I am having problems you didn’t have then

Ya it is strange. I can’t think of anything at the moment to try other that the built in linux fwupd. Maybe @anon26269396 has experience using it?

I’ve already found it before. It only said that UEFI ā€œdbxā€ could be upgraded. I’ve gone ahead and updated that, even before making the post.

Did not work with my Lenvov Thinkbook as Lenvov do not supply the correct format to be used by fwupd for my model.

Same thing I found and got from fwupd.

Just BSOD! Tried to run it as admin

Thankfully it seems I can just boot in back fine

Have you tried opening a thread on the Lenvov site for your model, maybe someone with that model went threw this already.

When you say extract, do you mean yours came in a zip file and windows prompted you to where you wanted to extract it?

Not yet. If things don’t work out today I’ll do that either tomorrow or the day after

I’m not being given an option to extract at all. I can only click on it, it seems to extract itself, then the wizard pops up. I don’t see any extra files anywhere though. No option to send it to 7zip or something either when I right click, only blueyooth, desktop, or my c device (that’s my linux system that windows can’t read) that windows is calling a usb drive lol

Have you resolved it? 7zip can be installed on linux so you could download and extract it there and then use the hirens disc to flash it if that is what the problem is? :thinking:

Maybe. Would it just be possible to install 7zip on the drive though rather than going back into linux? I can’t access the linux drive, and the reason I keep redownloading the BIOS update instead of copying it from a usb stick, in short only two usbs available on my laptop and the touchpad isn’t working for some reason on windows so I’ve been using a wireless mouse in the second usb I have

I’m sure you could put 7zip on the hirens disc. No harm in trying.

Edit: There is also another solution here. This is an ISO from lenovo to boot on.

wget https://download.lenovo.com/pccbbs/mobiles/g2uj28us.iso

Extracted it! Now just need to figure out the next thing to do lol
