To decompress some output file(s), simply pass -z <idx> where idx is the index
of the file to decompress, starting from 0. For example
upgtool -e NW_WM_FW.UPG -o tmp/ -m nw-wm1a -z 6 -z 7
to decompress files 6 and 7. To compress file, use the same options:
upgtool -c NW_WM_FW.UPG -m nw-wm1a -z 2 script.sh md5sum.txt system.img
