Hello,
I have Lenovo Thinkpad T450 and recently changed my LCD display with new IPS screen. But unable to control brightness in windows.
Please help me to remove whitelist for display and wifi. And unlock advanced menu too, and please remove that beep sound at startup too.

This is my factory BIOS: https://mega.nz/file/y2xRDCSD#fh1kQnYy9s...6wuVndIqt8
BIOS version: JBET73WW (1.37) 2019-08-14
Embedded Controler version: JBHT17WW (1.04)
Model is: 20BUS4S900 (Lenovo T450)

Thank you.

Thank you bro, much appreciated.
I tried but unfortunately it didn't work, It failed with message, "VERIFYING FLASH, A flash failed at address with offset .......... " and laptop didn't bootup so, i reflashed with original BIOS.

Is the original dump flashed normally? Did you use a programmer with a clothespin or desolder the flash drive?

Hello Bro,
Yes it is original dump from the BIOS chip with USB SPI CH341A without desoldering.

Thank you.

Sorry, my English is not my native language.
1. What software do you use for the CH341A? Not the one that was included, I hope?
Use alternative programs SiberiaProg, AsProgrammer or NeoProgrammer
2. Flash programming without soldering from the board = unpredictable result. In-circuit programming is very unstable.
3. Are you choosing the chip model correctly from the list?
P.S. recently, a person flashed Lenovo B590 without soldering, it was possible to flash only once from the 20th with disconnecting and reconnecting the clothespin.
