Recovery USB I recieved doesn't boot

I requested said Recovery USB for Latitude 10 ST2, emphasizing the unique needs of it's bizarre 32bit UEFI / 64bit OS, and was sent a 0KFWKP, which does not appear to support the tablet. It does not boot. SecureBoot enabled, disabled, or custom.

I had tried installing Linux instead, and learned a file "EFI/Boot/bootia32.efi" is necessary. This file does not exist on the thumb drive sent.

I do see on another partition named "DELL_OS_WIN8" on the thumb drive WIM, DAT, and CRC files.

I can boot into WinPE on the tablet. Is there a utility which would deploy those WIMs according to the specs in the DAT, onto the tablet's hard drive?

Or, what in addition to copying bootia32.efi to the thumb drive would it take to get this 8GB $20 POS working, or, perhaps there's a disk image somewhere for the ST2 that survived planned obsolescence?
