need dump for hp ProBook 450 g8 password

[Keg85]

Hello!
I wanted to post on the forum with a question about unlocking the BIOS, but during soldering, one of the EC ROM pins was torn off. The original EC ROM dump is permanently lost. I only have the original SPI ROM dump.

I replaced the original EC ROM GD25B256DYIG with a Winbond 25Q256JVEQ and flashed the dump from this thread. However, the laptop blinks 7 times and does not turn on.
I kindly ask for help in restoring the laptop’s functionality.

I restored the laptop, but the HP Endpoint Security Controller error appeared. I tried the script, it does not work for me normally. I deleted adress hameself (FF) it and a new error appears 32 times reboot and blocking. Please, Help bypass the HP Endpoint Security Controller error

Maybe someone has a suitable version for EC (bid T70)? I've tried many files from this thread, so far without success.

@Keg85 : Your version is T70, please find the correct version.

SPI file is corrupted.

sorry, i will try to re-upload the SPI file later, but for now can you edit the EC ROM file?

[hoaca388]

thank you for your help, however after I finished recording, the machine could not boot, the fan did not spin, everything was silent. I looked carefully again and discovered that this laptop EC ROM and SPI ROM are separate, the file I uploaded before was EC ROM, now I will upload both EC and SPI files, hope you can help

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Lol, thank you. That's way beyond my expertise. I thought I could use someone else's bios here, or there's one that's pre-programmed to flash out the password. I have no soldering experience. I appreciate your response, though.

Hi, I have this laptop that's locked with a BIOS password, so I can't access it to change settings. I am a noob and despite reading all the 11 pages on the site I have no clue what to do.
Can someone help me remove the password?
