Lenovo Y520-15IKBM unable to update BIOS

[pecka007]

Hello, i have problem with updating BIOS in my machine. Original updater starts running from Windows and then restarts to flasher, but it immediatelly says update failed. As in picture. If it is possible, i will try it with CH341A programmer, but dont know how.
BIOS update is from https://pcsupport.lenovo.com/us/en/produ...s/ds500049
I can make BIOS dump, if needed. And if it can unlock advanced menu, it will be great. Thanks a lot

Hi
First, make sure this is an update for your laptop model
Use the laptop serial number and find updates on the Lenovo website
