Okay, the DCM-202 firmware images (image1 & 2) are zlib compressed. I know this because of the reference to "Mark Adler" in the boot area. It's not lzma. It will not conventionally deflate because it is probably xor'ed, nor'ed or shifted in some such way to mask it from easily decompressing.
The file you downloaded "test_nonvol.bin" was the nonvol from a junk modem I got at a thrift store. It is the same model as my subscribed modem. I posted "test_nonvol.bin" to demonstrate the format or layout of the nonvol region of my subscribed modems f/w. I'll post some more info in a bit after I do some testing...
