Rot is black soft mushy roots. ... As stated already, the white roots do not take up water. Small hair roots will have to grow and this will take several weeks.

Give some water, may be flood the pot and let the excess drain off. Then give water when the top 1" of the soil is dry. Get a moisture meter to check moist deeper in the pot. ... I see both plants have a new cigar leaf, so it appears they were recovering.

If the new leaves and the plant foliage keeps dying, then a repot in course builders sand may be required. If so, cut the pstem just above the come to stop rot in the pstem and you being frustrated with the plants; and trim some of the roots. I don't expect you will see and growth until next spring. Flood the pot with water the first time; then give a little water every week or 2 if dry.
