丢失了 debug.keystore，我可以更新 Android 应用程序或检索应用程序数据吗？

Question

We have an internally deployed company app that has been signed with a developer's debug.keystore. The debug.keystore has been lost. Is there any possible way to:

1. Update a copy of the app using a new debug key.

2. Failing 1, is there any way an app with a new debug key could access the data of the already installed app (eg extract the data somehow, install the old and new apps side-by-side, adb uninstall -k)? The app does not have the debuggable flag set in its manifest.

I know the above is unlikely but I wanted to confirm before considering options as most stories about this concern Android market apps.
