Restore website from outside the admin console

Hi,
I broke my site after deleting:
- .cagefs/tmp
- Avada theme (inactive)
- broken Snapshot Pro files

Now I can't access the admin console at http://levonstore.vn/wp-admin. The homepage was inaccessible yesterday, but today I can access the homepage and a few categories.

I have change the plugins directory name to DISABLEDplugins and downloaded the latest backup files from Snapshot Program.

Please advise how I can restore the site.
Thank you very much!
