BIOS upgrades for Asus Motherboard?

My PC Specialist desktop is getting a bit long in the tooth now, and I've bought a new CPU to try and spice it up a bit. Trouble is, I need to upgrade the BIOS to support the new CPU, and I'm not having any success in doing so. I've contacted Asus support but I'm just posting here in case there's anything special I have to do because it came from PC Specialist? It's always displayed the Republic of Gamers logo on boot rather than a PC Specialist one.

**Removed reddit link, please post your issue here if you want support from here**

Case
CORSAIR CARBIDE SERIES™ 200R COMPACT GAMING CASE
Processor (CPU)
AMD A10-9700 Quad Core APU (3.5GHz) & Radeon™ R7 Graphics
Motherboard
ASUS® STRIX B350-F GAMING (DDR4, USB 3.0, 6Gb/s) - RGB Ready!
Memory (RAM)
8GB Corsair VENGEANCE DDR4 2133MHz (1 x 8GB)
Graphics Card
INTEGRATED GRAPHICS ACCELERATOR (GPU)

I have the above motherboard, which shipped with BIOS version 5603. I have tried updating the BIOS by downloading the ZIP files from https://rog.asus.com/motherboards/rog-strix/rog-strix-b350-f-gaming-model/helpdesk_bios/ and extracting them to a USB pendrive, then loading the CAP files through ASUS EZ Flash 3 in the BIOS.

I cannot update to any BIOS later than 5606 with this approach. I managed to upgrade to 5606 itself, so the approach should be fine, but any of the more recent BIOSes just gives me a "Selected file is not a proper BIOS!" error.

I'm desperate to update to 6042 or 6203 to support my new Ryzen CPU, currently sat in its box next to my desktop. Any idea how to resolve this? I tried doing an online update but according to my router that causes it to look for http://dlcdnets.asus.com/pub/ASUS/mb/idx/Z2/ROG-STRIX-B350-F-GAMING.idx which still says that 5603 is the latest version!

Any reason you're using EZ Flash rather than flashing from windows? These days any windows flash is going to be very reliable. The BIOS listing recommends flashing them also this way from 5008

If that fails, we need why it's failing, a screenshot with the error if possible

But I'd flash the latest BIOS, don't bother with any before.

To start with, I didn't have a Windows install! I've tried setting up a Windows 10 install but Windows Update doesn't seem to update the BIOS.

As I said in the post, EZ Flash 3 just says "Selected file is not a proper BIOS!" when I select any BIOS newer than 5606. I can get a photo of that next time I reboot.

I tried earlier versions just in case I needed to do an incremental upgrade, when upgrading straight to 6203 failed.

Well at least that gives me a different error! Now it says "The model of the BIOS image doesn't match the BIOS ROM currently present". But as you can see, the filename of the BIOS I'm updating matches the model name shown in the top right.

Found this:

Thanks for the tip. I had the right BIOS file, but updating it from within Windows gave me this error. Once I loaded it onto USB and used the EzFlash section in the BIOS, it updated fine.

Also, I'm not sure if it's the age of the USB stick that matters, but it needs to be formatted as either FAT16 or FAT32 file system (NOT NTFS or ExFAT, which some newer drives might be by default).

Unfortunately, using EZ Flash in the BIOS is where I started with this! I have tried the latest BIOS on two different USB sticks, both freshly reformatted as FAT(32) in Windows, and I get the same "Selected file is not a proper BIOS!" (see attached)
