Hi, When you say you uninstalled 8.x what exactly does that mean? That you deleted the directory of the binary *and* the solr home where the index data was stored?
Either way, check your logs (solr/server/logs in the location you extracted the binary by default) and you will see the exception that actually caused the Core Container to fail to start up, and that should give you a better idea as to the problem.
