I write this chip. Not KB9028Q...

I have already replaced the BIOS chip with a new one with W25Q64FVSIG. I have loaded roms that I downloaded from MSI support in various versions, but they did not work.
I use CH341A (black) board and neoprogrammer software for writing to chips.

When I press the power button on the laptop, power goes to the USB ports and the blue LED on the power button and the blue LED on the front start to blink at long intervals, there is no other movement, the screen is always dark.
There is no battery in the laptop. When I unplug the power plug, hold down the power button and plug...

Edited first message....

Thank you.
However, this file is already on MSI's site and I tried it did not work.
Did it work on your system?
I need the dumped files from BIOS and EC flash chips in a working system....

Hello, I am looking for original BIOS and EC flash dump files for my MSI GP62MVR 6RF laptop. The motherboard model is MS-16JB1. My laptop is currently bricked and I have already tried updating the BIOS and EC from the official MSI support page without success. I need working dump files from a functional laptop of the same model. Any help would be greatly appreciated. Thank you!
