No, this is the wrong way. You do not need to decompress the .wph file. 
The .wph file in this case is 1.5MB long with some extra data and code 
stuck on the end. So the first thing to do is to cut the excess after 
1.5MB off the end of that file. This 1.5MB is the top 1.5MB of the 2MB 
flash image**. Read the first 0.5MB from the flash device* and prefix it 
to the 1.5MB image to create the 2MB image. You can then program that 
2MB image to the flash device.

* If the failed update has corrupted this first 0.5MB on the flash 
device then you have big trouble.

** If you want to confirm that, disassemble the last 16 bytes of the 
1.5MB image, there should be a real mode far jump.
