as long as it has growth, it can be saved. It still may not turn into much tho. I agree with what many are saying, I'd trim off the dead leaves or the ones that look almost dead, bring it inside until it is stable no dome over it, give it some light, a cfl would be fine. It's already stressed as hell from having its root system raped, kill roots, foliage follows, it no longer has enough to feed the whole plant, die off is normal here which is why I trim off the dead and deadish leaves. Let the plant send what it can to the healthy parts. Baby it for a week or two, it very well could come back once it gets its root system built back up. Don't expect to see much new growth until that happens.
