# SwiftBackupPrem
Swift Backup Premium LSPosed module (tested on v4.2.3, v4.2.5 and v5.0.4, but should also work on newer versions - thanks to [DexKit](https://github.com/LuckyPray/DexKit)).

Optionally also allows you to set your own firebase credentials, so only your firebase instance is used.

It is highly recommened to set your own firebase credentials, because the developer can ban you from accessing original app using his firebase instance. 

Step-by-step setup for your own firebase instance:

Since October 2023 Google disabled Custom URI schemes by default for new projects. Check `Enable custom URI scheme` while creating Android OAuth client (~3:36 on guide video).
