Can't create FTF from PC Companion files with Flashtool

Hi
I've downloaded and copied the update firmware files for my D2302, however when I try to create the FTF file it freezes while processing the first file. The decrypted file it creates has no data in it. Any ideas?
Alternatively, does anyone have this customisation version in ftf form?

My end goal is to be able to have it rooted and if I'm really lucky, have a recovery. However, it doesn't look like [D230X.properties, in Flashtool data] it even has a recovery (which sounds odd, but I can't get it to go into recovery by power+voldn - it just goes through to system.)

Thanks
