The IPK posted in post #13 is themost complete package but still requires an internet connection because the package mtd-utils has to been fetched from the feed.
mtd-utils requires other packages/files e.g.
Depends: libz1 (>= 1.2.6), liblzo2-2 (>= 2.06), libuuid1 (>= 2.21), libc6 (>= 2.13)
But in Openpli 3.0 the installation should be fine as far as I know, otherwise you should try several times
