Ubuntu image doesn't work for plus, only pro

I don't know what the difference between the plus and the pro devices are (aside from the storage size) but I can't manage to get any image for the Plus model when the same iso works fine for the pro model

https://theminixforum.com/index.php?threads/neo-z83-4u-ubuntu-ubuntu-20-04-lts-image.3111/

this is the image I'm referring to
The only difference is NEO Z83-4 Pro has 32GB eMMC and NEO Z83-4 Plus has 64GB eMMC.
Apart from this, the hardware is identical and both run Windows 10 Pro OS.
 
@MINIX - John This is exactly what I figured the difference was

@linuxium I have CHTOC04-000 so I estimate that I'll need that BIOS update. I'm failing to understand though why the BIOS update hasn't been posted to the forum :/
 
@bnolet: I suggest you send an email to support@minix.com.hk and ask them for the 'CHT0C04001.bin' BIOS and flash your 'CHTOC04-00' device by:
  1. Downloading the BIOS.
  2. Unzip it and copy “fpt64bsw.efi” and “CHT0C04001.bin” to the root of a USB stick.
  3. Insert the USB stick to your device, and attach a conventional wired keyboard, a screen and power cord to the NEO Z83-4 device.
  4. Press the “F11” key on the keyboard when powering on the Z83-4. Choose the “UEFI: Built-in EFI shell”, then enter.
  5. Input command fs3: to go into the root folder of the USB stick.
  6. Input below command to execute updating BIOS process.
    fpt64bsw.efi /f CHT0C04001.bin
  7. When this process is finished, the BIOS is updated successfully.
Please note, during the updating process, do NOT unplug the power adapter.
 
@linuxium Alright, I've sent them an email. Hopefully I hear back from them soon.

Does anyone have any guidance on why this specific BIOS might not be posted directly to the forum? Once I get it, would I get in trouble by posting it here?
