Help to restore Bios MSI Bravo 15 A4DDR

Hi. I got laptop MSI Bravo 14 A4DDR with corrupted bios, fans spins but nothing else, no picture. I got CH341 bios chip reader, i was able to connect it with clamp to bios chip, i did two backup’s from old bios, got bios from msi website, did try to flash it without editing because i have no experience yet, first timer. After flash laptop started to come on, but it crashes randomly, i cant find any other fault so im expecting there is something still wrong with bios. Hwinfo gave error message saying that reading ec chip make unexpected longer reading time. Maybe someone could point me in right direction, bois1 is dump file and other is from msi webpage bios1 and 1 other file | Files.fm.

If you are sure that you flashed the bios properly without erros, there’s not much left. MSI does provide an EC update, maybe worth a try.

Tried EC update but didnt help, laptop just goes black screen frozen, from time to time. Tried disconnecting battery and lcd screen and now it worked without crashing, even at heavy load connected to tv, connected back screen and battery and crashed again, before crashing mouse pointer starts lagging.
