If none of the files work for you, look for another cause of the stick failure, not a bios error.

He read wrong Bios, there are 2 chipsets EC_ROM (usually winbond) and SPI_ROM (an MX). Your files are ok, I tested them.

Re: bios for hp PROBOOK 455 G8

Dear friends, i'm novice to forum, i can not exactly ask a question) ... I have an HP ProBook 455 G8 bricked after a failed BIOS flashing (under BIOS shell from wired connection). Do i understand correctly that DMI utility is no longer used in new models, and filling missing data in DMI is done in BIOS shell itself in MPM section? Is everything same as here? _https://www.youtube.com/watch?v=GuENOtU_B_w&t=264s
I still have a laptop warranty and i would like to know whether it is worth doing it myself (i have some experience).. ), or give it to service. Thanks for the answer.

Hey, i have a 455 G8 with remote management, no bios passwords, only can't get passed internet verification. I don't know what to clear/modify in HEX. Please help me with this one, too.

No, it's the password on your device, I can't do that.

Here are your Unlocked files, In the first boot go to Bios Menu and disable security options (Default).

Program this chip only, leave the other as is. At first boot enter the bios and reset bios settings to factory default, then reset security settings, then apply, restart and you're good to go.
