[REQUEST] Lenovo Thinkpad Edge E440 & E540 (J9ETxxWW) Whitelist Removal

[retardutyun]

Hi folks. Can you please modify this BIOS for E540 to remove wifi whitelist and enable advanced menu? Thanks.

I dumped the 8MB chip on the board with raspberry pi. Those two dumps have equal hash so i presume the dump was successful.

Also anyone knows the proper process to do it? I pulled CS on the other 4mb flash chip to 3.3v, but it still wasn't detected in like 9/10 attempts. Also i had to keep cs pulled to 3.3v all the time otherwise the two dumps had different hash. Also the default SPI speed on flashrom on raspberry pi worked well and dumped it in like 30 seconds so i didn't have to hold the cable there manually for too long.

Hello, I have a Lenovo thinkpad E540, could you help me to unlock the bios? I want to upgrade my WLAN module. So I need to remove the whitelist and unlock advanced settings and installing new battery.
The wifi module that I am going to install is a 7265hmw
