MSI RTX3080 10GB VBIOS update

[maverick_miner]

Hello All,
I have a MSI RTX 3080 10G & a EVGA RTX 3080 10G card and I wanted to update the VBIOS for it. I went through this link to flash the vbios (https://hiveos.farm/guides-flashing_video_card/) but the current version does not open the Polaris BIOS editor i.e. step 6 does not work. There is no proper guide to back up the Original VBIOS in case we want to roll back to the original version. So I was looking for a step by step guide on flashing the VBIOS and do not want to Brick my RTX 3080 card. I have below versions i.e one is a MSI and one is EVGA (LHR) versions. Any link or guide to flash these cards would be helpful.

Yeah… Sorry. I looked at the wrong link. I think this is correct link. (https://hiveos.farm/guides-flashing_video_card/#how-to-flash-the-nvidia-cards). But even this does not provide info about how to back up the current VBIOS from the card and then flash the new VBIOS.
