Hi, repotting is not the problem, watering too often is. Evergreens will look and feel dry when they're in trouble, but it's rarely due to lack of water, but getting too much too often. As well, you said you brought it outside 'again', without saying how long it was in, or what 'in' meant in terms of location. If it was dormant outside in the cold and you had it inside for more than a few hrs then you broke dormancy, then refroze it again all at once by putting it back out - a major cause of (very often) death... leaving it in the cold would have been much better. Unfortunately, it's a bit late now to do much but hold off on watering frequency til soil is more dry than anything, give it lots of sun all day long and cross your fingers... however, brittle foliage is usually a sign that all's is lost, whether or not it's brown yet. Let us know what happens within a few wks.

Thank you for your advice on not overwatering!

I'll clarify what I meant with the whole dormancy situation:

When I got the bonsai around Christmastime, the weather was still nice enough to have it outside in the sun. Right before the first freeze came, I moved the bonsai into my garage (which is unheated). I kept it there until the weather became nice enough to have the it outside in the sun again, which was a couple weeks ago. The bonsai hasn't been frozen, exposed to nice temperatures, and then freezing temperatures again. I've heard how harmful this can be to the plant, so I've been careful to make sure that didn't happen.

I'll hold off watering it for awhile and keep you updated! Thank you for your advice!

Freezing and thawing won't hurt your plant unless temps drop below killing lows, which will be somewhere south of 20* for the J procumbens 'Nana". There is good reason to keep your tree warmer than about 25-27* though, because some of the finer roots can be killed at warmer temps than roots more lignified. Killing lows are the temps at which water retained INSIDE of root cells freezes. Water in the soil and intercellular water can freeze solid w/o damaging the plant, but not the water inside of cells, which would be the last to freeze because that's where a concentration of solutes acts as a cellular antifreeze.

If your plant remains viable, it's in need of repotting, if only for the reason the soil is inappropriately water-retentive, something that doesn't sit well with junipers. If you have forsythia there, repot a week or so after they bloom.

If you kind of squeeze the foliage between the fingers and it kind of crumbles then the tree is dead.
