If anyone wants to play the firmware images, here are two quick&dirty scripts to extract and rebuild binary images:
extract_fw:
#!/bin/sh
img=$1
if [ ! -e "$img" ]; then
echo "usage: fakeroot ./extract_fw <img file>"
exit 1
fi
if [ $(id -u) != 0 ]; then
echo "you should run it with fakeroot:"
echo " fakeroot $0 $*"
exit 1
fi
img=$(realpath $img)
rm -rf tmp
mkdir tmp
cd tmp
tar xf $img
cd ..
rm -rf rootfs
mkdir -p rootfs
cd rootfs
tar xf ../tmp/rootfs.tar.gz
rebuild_fw:
#!/bin/bash
if [ $(id -u) != 0 ]; then
echo "you should run it with fakeroot:"
echo " fakeroot $0 $*"
exit 1
fi
version=$1
if [ -z "$version" ]; then
echo "usage: fakeroot ./rebuild_fw <version>"
exit 1
fi
cd rootfs
echo "$version" > etc/version
echo "building rootfs tarfile"
tar cf ../tmp/rootfs.tar .
cd ../tmp
gzip -f -v rootfs.tar
echo "$version" > fw.version
echo "updating md5 file"
rm -f fw.md5
md5sum $(find -type f|sed -e 's#\./##'|sort) > fw.md5
echo "building img"
tar cf ../MyPassportWirelessGen2_${version}.bin . --transform 's#^\./##'
cd ..
echo "done."
usage:
$ fakeroot ./extract_fw MyPassportWirelessGen2_1.04.17.bin
[...] make the changes you want under rootfs/
$ fakeroot ./rebuild_fw 1.04.17-fix-test-1
Hope this helps,
Gilles.
