Good (whatever time of the day you have) to everyone. I have Thinkpad a475 Serial: PF-1E7FT. I cannot find the device by its serial number on official Lenovo website, so here i am asking for your advice. Laptop doesnt turn on, but upon powering on fan starts for 5secs and turns off, while CPU heats up uncontrollably. When i was cheking both chips, i found out that W25Q80BL is almost empty (2 rows are filled, everything else is blank (FF)). Need your guidance good sires. Also, i have already updated W25Q128FV, but it seems to have no effect.
Here is the file with backups
