Just returned from climbing 5 Ecuador volcanoes including Chimbo... as of 2 weeks ago, Chimbo was in good shape for climbing; we had no problems. The traverse from the Vientimilla summit to the true summit was nicely hard-packed and easy. I understand that can be horrible sometimes, but not 2 weeks ago. The steep rock/ice/mixed section lower on the normal route was in decent, but not perfect shape. We protected it with ice screws.
