[REQUEST] Lenovo ThinkPad L450 (JDETxxWW ) BIOS Unlock

[kaiomatico]

Oh sorry I made a mistake. I flashed the original BIOS. It says again:

Error : Failed to verify Secure Flash image.
Error code = 234

So I'm now on the oldest BIOS from lenovo and ran: fptw64.exe -d dsk1.rom -desc

The file is in the attachment

EDIT: Flashrom is a stupid idea on Laptops. I just read it in the wiki. So this post can be ignored / removed

any updates on this topic? i think the solution would also work on my ideapad yoga with broadwell cpu

No news... the end of the story: you either have to get a hardware flasher (highly recommended option) or use flashrom (really risky and bad idea. I won't try this without a hardware flasher aas the chances are incredibly high you brick your laptop...)

Hi! 

I love this forum and the work its community does. Unfortunately I have troubles with exchanging my wifi card in my Lenovo Thinkpad L450 notebook and I would like to unlock my wifi card slot. Also configuring the DVMT would be best. 


What do you need to be able to modify my bios? Thank you!

I have managed to backup my BIOS. Unfortunately I cannot download the modded BIOS files for Thinkpad L450 in this forums anymore because they have been deleted. Hopefully somebody can modify my bios anyways. 

Lenovo L450
UEFI BIOS Version JDET61WW (1.23)

I have attached my BIOS. What do I need?

- Unlock advanced menu (to be able to set DVMT)
- Remove whitelist (to be able to replace wifi card)

Thank you!

Can someone unlock my Lenovo L450 bios all options + wifi whitelist. I didn't find any tools to extract my bios, so first if someone could send them to me.
