Thx a lot DanielDacko and RethoricalCheese for your awesome tool
Big news, customers came in, try 3 times is windows password, couldn't find it, reboot twice, and TADAAA, power-on security kick in.
So I gonna flash again with you modify bios, reset security and default setting, clean SSD, make a clean install and I should be fine

Can I flash an older bios dump of the same laptop? because I updated the bios after saving and reading a dump.

yes.. you can write any bios version of the same laptop.. keep the original so you don't have problems.. and you can write it back when you want..

I'm guessing it has something to do with windows autopilot. If it asks to log in to some company account after a fresh install and connecting to a network then it is so. Let's hope its not

HP probook 450 g6 i5, s# 5CD8376KT0 , BIOS CHIP w25q128JVSQ - 1930/ Suddenly popup BIOS Password+ keyboardLayout /
After BIOS write EZP3 program/ Power button not respond with battery or without battery/ Only orange light constant blinking/
Is it keyboard issue?
Or BIOS chip need to replace?
Or Firmware file corrupted?
Its my first time to ask help.

My password blocked bios file is attached. RCUnlocker missing component to unlock. Anyone with big heart could you please check? I believe lots of people including me appreciated.

The backup file failed so RC unlocker can't work. Your file has been corrupted.

You have destroyed your own machine with your own hands. What to do now is to select a bios file here (https://www.badcaps.net/forum/showth...probook+450+g6) to get the machine working again.

Bios chip Winbond 25Q128JV, is a complete analogue, compatible in all parameters with the MX25L12873F chip of another MXIC manufacturer.

The numbers "1930" on chip are the coded date of manufacture of the chip housing. 19th year, 30th week.

hoaca388 -- Huge Thanks. We can enjoy Long weekend. Machine boots normally.

all the bios posted are different..probably you wrote the bios chip with errors..remove the bios chip from the motherboard before writing or reading..do not empty the clip, it gives errors if the contact is not firm...what programmer are you using??

In the first boot , you have to go into bios setting for disable all the security features.
