Hm,
Maybe you flash is full.
Ok you can try this one to install manually i have mod with dreamboxedit
Copy file to /tmp
and install with
green >>yellow>>Manually Install Bh packages.
I have test this files and working on my box.
============================================================
If this not work I think you have to try to put/ftp files with Dreamboxedit program for windows.
The negative for updates and install online is not being cleaned old files
That is why is better to use dreamboxedit,which erase files not in use (old files) and controls the validity of files .
