Possibly your boot block (or PEI volume, as it is called in EFI-land) is toast. Or maybe the BIOS has to be repackaged as a "recovery capsule" (Phoenix's documentation uses this term). Maybe try the WPH.
EDIT: Seems like a "recovery capsule" is simply an EFI Firmware Volume, containing the entire DXE (second-stage) part of the EFI BIOS. If it is true, then it should be easy to produce from the full BIOS image.
EDIT 2: Found the "recovery capsule" inside the V1.22 Windows flasher. Will try to find the V2.04 one and post it here.
EDIT 3: Here is the V2.04 "capsule": http://ifile.it/oveg4nx/FvRecovery.fd
And how to get it from any BIOS version:
1. Run the Windows flasher on a mismatching machine (preferably one that does not even use Phoenix SecureCore Tiano).
2. When you get the "Platform check failed" error message, navigate to %TMP%WinFlash using Explorer.
3. The file "FvRecovery.fd" is your recovery capsule. Rename it to BIOS.cap and burn it to a CD or copy it to a Flash drive.
Note: While you are in the WinFlash directory, take a good look around - there may be other interesting files in there.
