X280 NM-B521 bios no display

[Nairolf]

Hello,
I used HP Unlock tool to remove my bios password but i think it doest work correctly.

Step followed :

1. Unsold the W25Q256JVEN Chip
2. Dump memory
3. Drag and Drop to HP_unlocker.exe
4. I have written to memory the new file
5. Solder the memory to the motherboard
6. Start the computer and i will try to enter in the setup bios menu. At this moment i have loading bar "repair..."
7. Windows startup
8. i restart the computer and i'm trying to go again in the bios setup but the password is always set.

Anyone can help me please ?
Maybe it's HP Wolf security ? or a software who run a script on windows startup ?

Use RC unlocker , don't use HP unlocker.

I've already flashed the BIOS using my brother hoaca388's BIOS. Same problem, no power.
I need to repair the EC BIOS.
