    Unfortunately the unlocking is done on the EC chip but with the condition that the original bios is kept. In the forum, there is a case of losing the original bios and everything is coming to a standstill.

            Re: hp probook 450 g8 bios lost

            How did you solve your issue? I had a bios locked 450 G8, i removed chip to read and got someone else to remove password. I flashed the .bin that they gave me to the chip and was in manufacturing mode. Then removed the chip again and was told to flash back the original .bin (which i still have). I then tried updating the bios from inside the bios via ethernet. It had 5 updates to do. On the 5th update, it said finailizing bios update, then retarted into a constant bootloop. Since that, I can no longer get it to boot anymore and it flashes 7 white on num lock, indicating bios. Any help would be appreciated.

              probook 450 g8 - not sure if programming is correct

              I have a bios locked 450 G8 (was locked actually), i removed chip to read .bin and got someone else to remove password. I flashed the .bin that they gave me to the chip and was in manufacturing mode. Then removed the chip again and was told to flash back the original .bin (which i still have). I then tried updating the bios from inside the bios via ethernet. It had 5 updates to do. On the 5th update, it said finailizing bios update, then retarted into a constant bootloop. Since that, I can no longer get it to boot anymore and it flashes 7 white on num lock, indicating bios. Any help would be appreciated.

              the 3 attached are
              1.probook 450 g8 is the original locked bin
              2.unlocked-probook 450 g8 is the .bin that someone unlocked for me from the original
              3.newprobook450g8 is the .bin i was told to flash after i explained the bootloop situation.

              the guy who unlocked for me doesnt speak the best english and i feel some sort of miscommunication mightve happend.

                                    I need a BIOS dump for the Samsung S49CG934SU monitor
                                    by Habble7
                                    The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                    Suspected Cause:
                                    I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                    Troubleshooting Attempts:

                                    Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                                    I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                                    Hello.
                                    I tried to add a custom secure boot key (for secure booting Linux) to my bios, but after this, my laptop bricked. After adding secure boot key (via PowerShell) and enabling secure boot my laptop turns on, shows HP logo, and after 5 seconds it turns off and on, and it repeats forever.

                                    My goal is to either turn off secure boot or remove my custom key from BIOS dump.

                                    I'll attach my bios dump (version R79_011700) from my bios chip 25b127dsig, my keys (PK/KEK/db), and bios dump from another HP ProBook 445R G6(I found it on this forum. URL: https://www.ba...

                                    Asus Vivobook S14 Flip OLED TP3402 AFUWINGUI memory dump error for decoding lost BIOS password

                                    Hello everyone,

                                    I'm an owner of an Asus Vivobook S 14 Flip OLED TP3402 laptop (TP3402ZA-KN063WA)
                                    with serial number: NBN0LP019584459
                                    and I lost the BIOS password that I set in this laptop one year ago.

                                    I tried to recover the password using the AMITSESetup method described on the forum. I found that it is possible by software to obtain the BIOS file from my computer (afuwin.rom), but when trying to do so in AFUWINGUIx64 I received the error number 31 "Unable to read contents from specified file" shown in the attachment. I don't have a programmer,...
