I am dabbling with this too.
Tonight I just did the following:
I used the V5tools_v1.2.tar.gz from the megaupload link in the
Russian thread at the-ebook forum.
Code:
#!/bin/bash
echo "unpacking v3asetup.bin"
./mkv3update --unpack-v5-128=v3asetup.bin zImage.v3a ro.fs.v3a root.fs.v3a logo.v3a user.fs.v3a
sudo ./fscramfs_32M -x rootfs.v3a root.fs.v3a
sudo ./fscramfs_32M -x rofs.v3a ro.fs.v3a
I took tocer's tip of using the v5 script, and it appears to work.
I get:
Code:
drwxr-xr-x 19 root root 4096 2010-11-20 20:42 rofs.v3a
drwxr-xr-x 4 root root 4096 2010-11-20 20:42 rootfs.v3a
each with appropriate file systems in them.
