I did reprogram the main chip with bin file you provided but i also de assembled and reprogrammed the chip which is located at back of board. Saved original bin then unlocked with hp unlocker. But laptop doesn't power up now no sign of light even the charging plug on. No light on keyboard.

Thank you for your help. I followed your instructions but encountered an issue. I received a message indicating that the BIOS blocks don't match and that I need to update the BIOS. However, when I reached the battery screen (the battery capacity error message due to the battery not being connected), the system froze.

Upon restarting the laptop, I observed six orange flashes and then nothing happened. I removed the chip again and compared the files, noting that some changes had been made.

Do you have any suggestions on how to proceed?

flash this main and the original locked EC.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
after following my instruction to get rid of Manufacturing mode. use BCU.

Could someone please help remove the password from the attached files?

I've attempted using the unlock tool, but it still prompts me for the password.

Attached are the files from both ICs and the unlock files as well.
