Hi
You need SPI-programmer+SOIC8 clip only

Dudu2002 I have programmer and rpi and a soic8 clip...I've corebooted my x220 so I'm familiar w/ dumping the eeprom...is there a diagram/faq on how to dump the bios for the w540....when I connect the programmer to the chip is the pin placement the same to dump the EEPROM; that's the question I'm asking?  I'd like to get a whitelisted BIOS to install an OKN WiFi 6 AX200 card.  I apologize for the lame question... I just wanna make sure my dump is valid.  Thanks!

It seems that there has a way to selfsign the RSA. so maybe we can find a quick way (automatic tool/script) to modify the whitelist and generate new BIOS file.

Hi
Incorrect dump
Check your PM

OK I send the two files to you. Must I programming it via SPI too or could I reassemble the device?

Hi,
I tried to find the Universal Bios toolkit but unfortunately I couldn't find any one which can run it in my W541 to backup the bios. I have got a same issue as you. I want to change my laptop wifi card. If you already get this issue sorted, it would be very appreciated if you can just send me the bios file and the Universal Bios Toolkit which you used to unlock your device.
