kindly help rescue a no-ID, if possible?

Hi!

I wasn't sure which actual forum section to post to, whether the potting/repotting or here in the pests and diseases.

A friend of mine recently lost her orchids, they just died off for unknown reasons. She is aware of my growing interest in gardening as a hobby, and so gave me the last one in an attempt to save it. No clue what it is, all I know is that it was in a large-bark medium.

I've read and watched several videos on the internet for rescuing orchids with no roots.. here's what I'm attempting: 1) a little water in a jar, 2) put double hydroton volume of water, 3) rest the orchid atop hydroton (don't bury), and 4) drape ziplock bag over it.

The pictures show it after a week this way - the largest stalk has wrinkled a bit. I don't think this technique is working. I made circles in the closeup photo, here's the description
- Red circle is squishy.. actually, that whole core thing feels squishy, kind of rotting?
- blue circles appear to be roots, when wet, some are green
- purple appear to be new leaf shoots/buds

Both purple and blue circle items were there when I acquired the orchid, not a result of what I've done the last week.

Would appreciate any more advice. Chances are, this will die, so I'm looking at this as an opportunity to learn, and if I can bring it back, would be pretty cool .

Thank you for any help
