First, I am going to assume that the question is, "What would have happened to Earth if, during the formation of the Solar System, Jupiter had grown to be a large brown dwarf rather than a moderate-sized gas giant."
This is a difficult question for two reasons. First, while we've made excellent progress in understanding the formation of planets, we still have a lot to learn. Secondly, the process is usually chaotic in the technical sense, where small changes at early times can produce arbitrarily large changes in the final results.
So one point right off the bat: Possible outcomes include the Earth and other small planets being ejected from the solar system or impacting the Sun or UberJup. Based on what I recall from reports on detailed modelling, I'm pretty sure that most of the asteroid belt would be ejected and possibly Mars as well. There a paper at http://iopscience.iop.org/article/10.1086/300695/fulltext/ which presents simulations of planets in various binary system to determine orbital stability. (Note that it doesn't actually look at the brown dwarf case, but the lowest mass case it does consider gives us hints. Also, note that it only looks at 10,000 "years", and that we know from other work that instabilities can happen much later.)
However, given those caveats it looks like stable orbits can exist inside about half UberJup's distance from the Sun. Since UberJup is at about 5 AU, we can reasonably expect all of the inner planets (including Mars at about 1.5 AU) to have stable orbits.
This is for the case of a low-eccentricity orbit for UberJup, since a higher eccentricity makes the inner planets less stable.
Bottom line so far: The inner plants could survive in stable orbits, but there is a non-trivial chance they wouldn't.
There's a lot of cutting-edge work on planetary migration, which I've not considered and which probably decreases Earth's survival chances. Basically, once you're not looking at ultra-close approaches -- cosmic billiards -- resonance effects become important. Resonance effects don't even require huge masses. Basically, if, say, Earth and Venus had orbits whose periods were in a small integer ratio: 2:3, 1:2, 3:4, etc., they occupy the same relative positions again and again and again and even very small gravitational effects can build up and, slowly over time, planets can exchange surprisingly large amounts of energy and momentum.
It appears that in the actual history of the Solar System, Jupiter and Saturn did just that and moved first in to perhaps half their current orbital distances and then out before settling down where they are today. I have no idea how replacing Jupiter with UberJup would affect this. It could be simulated, but it's beyond my ability and I know of no one who has considered this problem. (Which is not to say no one has -- the literature is very large.)
So let's forget all that and look at the minimum changes case: UberJup sits where Jupiter sits. The inner planets are basically unaffected in their orbits. The asteroid belt is probably nearly empty. Outside UberJup's orbit there are probably some gas giants and neptunes, but their arrangement and number is probably different than the Solar System's. The arrangement has a reasonable chance of being stable.
One potentially big change is that the clearing of the asteroid belt would probably have resulted an an increased very early bombardment of Earth, so the Earth might be a few percent more massive than it is today. It might also have a second natural satellite, though much smaller than the Moon.
Finally -- here's where chaos comes in -- there's a good chance the Moon would not exist at all. It appears that the formation of the Moon happened due to a glancing strike of one of the last planetary embryos on a nearly complete Earth. This splashed a lot of matter into orbit, some of which coalesced into our massive Moon. It appears this is a fairly low probability event, so the presence of UberJup might well have erased our giant Moon.
