Because it is INVALID, your 16MB file is corrupt, the offset 422000 should start with LENV, then what looks like garbage (it's encrypted) until you see a repeating pattern, at 423000 it's similar, starting with LENV; yours it's repeating 03 FC 03 03 FC 03 ...., either a bad read from the chip (if you used a clip, bad connection), or the BIOS chip was very corrupted...
Use Golden Key USB to enter serial, MTM, model name, if it doesn't work Flash the clean 16MB file from post 4 again then try Golden Key again

I have laptop Lenovo IdeaPad 3 15ITL6 with Intel Core i3-1115G4. When I press the start button, LED light on the start button starts blinking 12 times, then stops and after some time starts blinking 12 times again. When it stops, all voltages are down.
The motherboard is HS460 HS560 HS760 NM-D471 Rev: 2.0
S/N: PF3Q0WTF
The motherboard is not mine, also there were corrosion on the board which I cleaned.
Methods of fixing like fully turning off the motherboard or starting only with adapter doesn't work. All testing were did only with adapter on.

Hello
I've got a Lenovo that stopped working. No sign of life at all. I was hoping it would be an easy fix but I am not sure it's mosfet, I think resistance should be low but it's OL.
Thermal camera show MOSFET heartbeat.... It's Sinopower SM4377.
Thanks
Sam...
