It should work, verify your soldering and be more careful.

maybe it will restart 2/3 times so be patient

Hello, from what I understood is that you unlocked your bios, and then you don't have an image, is that it? it is supposed that with your original bin everything should be as before.. it only occurs to me that a component near your bios blew up... send a close up image to verify it I have plates here to compare.

no , After modifying and installing the Bios chip on the motherboard, the aforementioned error occurs

thx for help but the same problem

Then I lift the chip again and read it, I find a difference from the original file that I read before installation
