Bios Mods -The Best BIOS Update and Modification Source

Hi

Im looking for help with bios mod for T450.

BIOS: JBET73WW

I need whitelists (LCD, WLAN and WWAN) removed and adavnced menu added.

I have tried to remove LCD whitelist and it worked (I can adjust brightness) but I cant deal with 2x 5 beeps on boot.
Im not sure if I made mistake with modding or I need to set something else in bios.
I have tried setting security chip to disabled and inactive but I still get beeping.

Link to original bios dump: https://drive.google.com/open?id=18a8WAq...a96OSh6Csg

Kind regards,
banita

Hello, I looking to unlock supervisor password a T450. Model is 20BU-S1GH00. I made backup of rom file with CH341A flash writer, I tested this rom file and it's correctly and working.

UEFI BIOS version jbet49ww 1.14
Embedded Controller version jbht13ww 1.00
ME firmware version 10.0.38.1000

Hello

Can someone help me unlock advanced menus and remove whitelists of my T450 ?
If possible, also remove Computrace ? 
Bought this one 2 months ago at an auction, but only noticed now that Computrace was active and the seller is no longer on ebay.

UEFI BIOS version JBET51WW 1.16
Embedded Controller version JBHT14WW 1.01
ME firmware version 10.0.38.1000

The BIOS chip is a W25Q128FVSQ, but CH341A versio 1.18 recognized it as W25Q128BV. Hope this is ok.

Hi
Your bios is rewrite protected...you need a SPI-programmer+SOIC8 clip only!

Hi guys,

Please, find attached the bios from thinkpad T450 20BV0005US that needs to clear whitelist for lcd and wifi and also enable advanced bios menu,

The backup has been done with BACKUP_Tools19n and I do not have any bios programmer.
