Lenovo ThinkPad S440 Wi-FI BIOS Whitelist Removal

Recommended Posts

Hi!

I would love to have my BIOS modded to disable the wireless whitelist.
I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.

Laptop: Lenovo ThinkPad S440 (TYPE 20BB-S00400)
BIOS version: 73ET71WW (1.71)
Original WiFi/BT card: Intel Wireless-N 7260 (7260HMW BN) (vendor: 0x8086, device: 0x08B2, subdevice: 0x4262)
Target WiFi/BT card: Broadcom BCM94352HMB (I haven't received it yet, waiting for delivery)

Manufacturer BIOS download: bootable ISO, updater for Windows

My BIOS dump (using CH341A SPI Programmer under Linux): http://www.mediafire.com/file/mn0gfr9ext7yqrn/S440_73ET71WW.bin/file

 

Thanks!

Hi! 

In your laptop model, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in this thread:  

You can post here or send me your file backup (dump) of bios. For creating backup (dump) of bios you need to use hardware SPI programmer.

      I've been scouring the internet in search of anything regarding an updated bios for my Clevo P170SM. I have found many mentions of Prema Bios mods on various websites, but good luck trying to find actual download links. They all seem to vanish or have dead links. Wayback Machine doesn't help either and I was only able to find stock Clevo bios as early as 2015 via the WayBack Machine. If anybody has an updates Prema Bios or some other unlocked bios file for the P170SM, that would be fantastic! Otherwise, I might have to consider paying over $100 to Eurocom for their unlocked bios.
