Dendrobium Amabile SOS

[PuiPuiMolcar]

I love dendrobium but this particular one hates me and I too hate it. It's one of my parent's near death orchid that I tried to revive last summer, I repotted it in fresh bark medium and it gave me new growth but that growth wilted and dehydrated at the end of the summer. It was grown under dappled sunlight, and let it dry in between watering.
I'm not even sure if it is salvageable, but it's winter now so I dont know what can I do for it to get through the cold spells. I wanted to check its root, but I'm afraid it wont be able to handle another uproot shock.
this is the first dendrobium that failed on me.
