I am trying to unpackage firmware. The file command gives me this.

gzip compressed data, ASCII, has CRC, extra field

gzip -d gzip.gz gives this.

gzip: gzip.gz has flags 0xcf -- not supported

Any suggestions?

What version of gzip do you have? – cybernard Aug 23 '13 at 3:05
"gzip 1.5" is the version of gzip that I have. – user247819 Aug 23 '13 at 3:09
