Hi,
I looked up at the backup options that I could possibly do and found out that basically this model is unsupported by major backup tools (like ClockWorkMod, etc.), so potentially I can brick my phone if I try to do a backup by applying settings from other models. So I can't risk that, I've googled other people and some have already bricked their phones using ROM Manager, trying to do backups for their unsupported versions.
Sorry that I can't get you a recovery image.
I've decided not to mess with my own LA905 since apparently, there are no stable custom ROMs for it available (unless somebody with coding skills made one, we have to file a request for that, however.)
It's not hopeless, however, I would try searching for Ulefone N9005 firmware as I've mentioned before.
