HP Elitebook x360 1030 g2 flashed but not booting

[Souricier]

I have finaly bought a T48 programmer and I succeeded in flashing my chip.
I put it back on the motherboard but now the laptop is not starting and the power is blinking orange/white with a lock on the keyboard blinking white also.
I have removed battery but same error.
Do you have any clue ?
Thank you for your help

What is the origin of the bios image? Is it a known good image? Bios forum can help with specifics of the bios.

What is the history of this motherboard?

It's a long story described here : https://www.badcaps.net/forum/troubl...2-with-ezp2023

The BIOS image was provided by an admin of the forum and the laptop was running well before I removed/flashed/replace the chip...

Is it true that on his HP model there are 2 chips for BIOS ?
What is the mecanism of these chips ?
I flashed only one and my laptop does not start anymore. Someone says to me that if the other chip is not similar to the patched one, it will not start... False or right ?
