Your bios is rewrite protected
You need a SPI-programmer+SOIC8 clip only

But you can unlock this?

Sorry... my english is very bad. Use translator.
I can change hidden settings directly by flashing nvram. If I change the frequency settings of the RAM to invalid and the laptop stops loading, can I reset the settings successfully? The frequency of RAM is 2666MHz. I want to change to 2800/2933/3000 ... I found where this parameter is stored.

I have the (much older) Y700 but maybe it helps as it's bound to be similar (I was posting in another thread and saw your post):
- If it can't run at the frequency you set, it will revert to the default settings and restart. Just give it a while.
- Changing some other (hidden) settings (possibly including the memory training algorithms) can cause a boot loop. In that case you need to take off the cover, unplug both batteries (and the AC adapter) and wait for a moment to clear all the settings

Hello !
I bought my Lenovo Legion Y540 and i want to unlock my bios for advanced tab to edit voltage offset.
My bios version is BHCN35WW
Could You help me ?
Attached original bios.
Ok, i know i need SPI programmer but is it possibile to reflash without unsoldering, using only SOIC8 clip?

Hi,
I would like to ask some one to unlock my BIOS. I have to files:
BIOS_1 is extracted from lenovo bios update file
https://www.file-upload.net/download-139..._1.fd.html
BHCN26WW is read out by using Universal BIOS Backup ToolKit 2.0
https://www.file-upload.net/download-139...W.rom.html
It is the same BIOS.
