Hi guys,
I had my 15/bs0xx broken after bios update (v. 73) from official hp software.
I flashed my bios with CH341A and clip (only mb , i removed all on mb).
I tried unsuccessful with official bioses (73, 72, 69 e 57).
i tried successful with 8328B.zip and HP 15-BS525UR,LA-E791P REV 2.0_MAIN.zip on this post.
Many thanks.

My details:
HP Laptop 15-bs0xx
