Hello guys
so i got my new motherboard asrock b550m steel legend from aliexpress with bios update 1.60 that doesn't support Ryzen 5000G series
So i went to a pc shop and update my motherboard using a Ryzen 5 3400G to latest version 2.20 that support 5000G
however i still dont get a signal and im getting in debug screen BOOT VGA CPU light
so when i went to bios version page https://www.asrock.com/mb/AMD/B550M%20Steel%20Legend/index.asp#BIOS" rel="nofollow - https://www.asrock.com/mb/AMD/B550M%20Steel%20Legend/index.asp#BIOS i found this with yellow -To support Ryzen 5000 G-series processors, it requires to update the BIOS with Matisse, Renoir or Vermeer CPU -
my two questions are : 1-can i reflash the same bios version 2- does flashing the motherboard with 3000/4000G/5000 cpu is necessary to 5000G to work cause i flashed it with Picasso 3400G

You need a to update the BIOS with Matisse, Renoir or Vermeer CPU only, not a g series.
