Update-Problem, Shop hängt im Wartungsmodus

Hallo, ich habe hier leider ein Problem mit Shopware. Ich wollte den Shop updaten (übers Backend), lief auch alles soweit durch. Beim Cleanup kommt allerdings eine weiße Seite mit diesem Fehler:

Slim Application Error

The application could not run because of the following error:

Type: Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException

Offenbar ist das Plugin DHL Wunschpaket schuld, möglicherweise ist da beim Update, was ich davor gemacht hab, was schiefgegangen. Sowohl Frontend als auch Backend sind nun zu, ich komm nicht rein. Kann ich das Plugin von außen irgendwie deinstallieren? Oder mich sonst irgendwie wieder ins Backend bewegen?

Suche in der Datenbank die Tabelle s_core_plugins und setze den Wert active des Plugins auf 0.
