theano/sandbox/cuda is the old gpu back-end that work with device=gpu*. theano/gpuarray is the new back-end with device=cuda*. Don't mix both of them, it won't work.
Can you try this PR: https://github.com/Theano/Theano/pull/4862 and use theano.tensor.nnet.conv3d()? This add the good user interface as conv2d to conv3d. Hopefully, we will merge it this week.
