https://www.google.com/#q=unity+texture+readable

By default all textures are "locked", so once loaded into the GPU you can't read them back via code. You can set read/write enable to true in the Texture import settings to allow read and write operations on the texture. Choose Texture type: advanced.

When I set Texture type to advanced and click apply, Unity always reverts the changes back to Sprite. Is unity broken or am I somehow doing something wrong?

Can't say for sure since i haven't used the new sprite type yet ;) I don't think it's the type that's a problem. It's probably that new 2D IDE mode that might prevent you from changing the type to anything but sprite.
