MSI B350 Gaming Plus failed BIOS update / how to recover?

[explodinator22]

This is my first post so please bear with me...

Recently I decided to update my Motherboard to version 7A34vMD from 7A34vMA but instead of using the normal method of M-FLASH I used an AMI flasher for your desktop (specifically the one from America Megatrends) and forgot to choose a full reprogram, it only programmed the main block. Now the system won't post. Its specifications are:

MSI B350 Gaming Plus
AMD Ryzen 3 1200 (no overclock)
8GB Corsair Vengence LPX 2x4GB (CMK8GX4M2A2400C14) at 2400MHz (I had A-XMP on)
GTX 1050 Ti 4GB from Zotac
1TB Seagate Barracuda HDD
120GB Kingston A400 SSD

I've tried the fixes from https://www.bios-mods.com/bios-recovery/ami-bios-recovery/ and https://service.msicomputer.com/msi_user/support/techfaqdetail.aspx?formid=3046 but those 2 don't post to the USB drive I'm using (Sandisk 64GB formatted to exFAT)

Is there any way I can successfully recover my motherboard to an earlier BIOS version? I really don't want to RMA / Take to a technician to get this fixed.

Thanks in advance!

You need to format the USB drive in FAT32, make sure you move other folds or other empty USB, before you format the drive. Then download the BIOS into that USB.
After that try to recovery the BIOS again https://service.msicomputer.com/msi_user/support/techfaqdetail.aspx?formid=3046

Ok thank you for your reply. I got a drive formatted into FAT32 and put the BIOS onto it, how long does it usually take to show the recovery page?
