[REQUEST] Lenovo ThinkPad W520 (8BETxxWW) Whitelist Removal

[JazJon]

Hey All,

Problem)

I'm getting tired of my W520 WiFi network getting stuck in "Limited" and rebooting is the only fix multiple times per day.
This blog post says to try changing WiFi properties from AES to TKIP. (but that's not a choice)
https://msmvps.com/blogs/richardfenn...windows-8.aspx

Option 1)
It's time to change the mini PCI WiFi card but I learned that Lenovo has this wonderful Whitelist "feature" for our safety.

Can someone help me create a W520 BIOS to remove my whitelist?

I'm currently running BIOS 1.42 on the Thinkpad W520 Type 4270-CTO (Windows 8.1 x64)

I have Intel® Centrino® Ultimate-N 6300 AGN

PCI\VEN_8086&DEV_4238&SUBSYS_11118086&REV_35
PCI\VEN_8086&DEV_4238&SUBSYS_11118086
PCI\VEN_8086&DEV_4238&CC_028000
PCI\VEN_8086&DEV_4238&CC_0280

Option 2)
I read that some Thinkpad's have second miniPCI slots that are not monitored by the BIOS whitelist. Anyone know if my Thinkpad W520 Type 4270-CTO has a second slot? Either way it would be nice to unlock my BIOS. I've googled around this this request thread seems to be the place to ask.

Thanks!

EDIT: I just searched a 2nd time via google, now that I know to add the word W520 BIOS SLIC
I found someone posted it already, sweet

(trying it now)

EDIT 2: When I run winflash.exe and choose FvRecovery.fd to flash I get error Cannot Launch the UEFI Emulator.


EDIT 3: I found WinPhlash 1.7.16.0 (newer than the 1.5) So far it's working, I'm making this final post before I press ok (crosses fingers)

EDIT 4: That didnt work, got a new error
Corrupted interface descriptors in the new BIOS file Part Table Signature not found in the interface. Error code - 161


EDIT 5: I re-read the original post and it said
Flash from Windows. Run WINUPTP.EXE /s as Administrator.
So I opened my start menu (press start button) typed Command, found the command prompt. Right Click, Run As Administrator
Changed directories over to where winuptp.exe was
WINUPTP.EXE /s

Success! (I think) The whole system slowed down for a minute and then returned to normal. I'm pretty sure that means the silent update took. Is it safe to order a new WiFi card now? I want confirmation it worked.

EDIT 6: Yes, the flash happened after the first reboot!

I have 3 antennas but I read I only hookup 2 since the new card is 2x2

Thanks for the MOD guys! This new firmware should do the trick. I posted in great detail in hopes it helps someone else.
