Help! Is my Phalaenopsis totally dead or there is chance to revive?

[lees0118]

Hi everyone! I am a beginner in orchid growing and realised that my orchid seems to start having root rot after I bought back home. I believe I may have overwatered it. Currently all roots are dried up & hollow (and I have cut them off)

Two leaves have turned yellowish & wilted, it still has 2 green leaves now. The stem is getting dried up & turning brown. Some of the buds didn’t even bloom and just wilted straightaway.

I have attached some pictures for better illustration.
I wonder if there is chance for this orchid to be revived?
Appreciate your kind advice !!thank you!
