Bios version 315

So i recently checked the latest available bios for my asus tuf fx506he-hn and it was 313.

But when i checked it in bios it said 315?

I bought it directly from asus as "repackaged, not used" (translation from an other language).

When i searched for bios version 315 every result said Zephyrus, and how fucked up the version is.

Wifi problems Bluetooth problems, so much complaints.

And i do have both wifi and Bluetooth problems. My laptop sometimes refuses to connect to wifi, and even if it does it says "connected no Internet". Bluetooth just straight up dissappears sometimes.

Might not be the same bios as for the Zephyrus but i sure do have the same problems.

Should i downgrade to 313?
