Dear xiiao1047,
Perhaps try to flash the bios via DOS mode?

1. Download BIOS: http://my.msi.com/product/mb/870-G45.html#/?div=BIOS
2. Create a bootable USB: http://www.techpowerup.com/printarticle.php?id=34
3. Extract the downloaded file into your USB Root.
4. Boot to your thumbdrive via F11 or via BIOS selecting your USB as the 1st booting device.
5. After successfully booting into DOS, type AFUD4310 A7599AMS.A80
6. System will flash the bios.

Or. you can RMA it, send me your S/N and i'll advice you which disti to RMA it.
Or. you can send it to MSI Malaysia and we will RMA it on your behalf.

Note: I believe what MSI-MY adviced you to flash the bios is via M-Flash. IF via M-Flash you shouldn't be having the BIOS Recovery error seen because you need to flash it "inside" the BIOS. Here is how flashing bios via M-Flash is done.

1. Download BIOS: http://my.msi.com/product/mb/870-G45.html#/?div=BIOS
2. Extract the downloaded file into your USB Root.
3. Plug in your USB into PC.
4. Start your PC and Hit Del to enter BIOS.
5. In BIOS, select M-Flash
6. Find a option sound like "Update BIOS...."
7. Navigate it to find your USB and eventually the BIOS File.
8. Hit enter once you found the BIOS file and it will flash automatically.
