Backups in modified WhatsApp clients are not always interchangeable with official WhatsApp or with another phone. Treat backup, restore, and migration as three different tasks—each has its own limits depending on your APK version and Android version.
Backup failures may be caused by low storage, missing Google Drive or local folder permissions, or a build that does not support the backup type you selected. Note whether the failure is immediate or stalls at a percentage.
Restore usually requires the same app variant and a backup file the app still recognizes. Restoring over existing chats without reading prompts can overwrite data you meant to keep.
Moving from GB WhatsApp to official WhatsApp may not transfer all message history, settings, or media—Meta does not support importing unofficial databases. Plan exports and realistic expectations before uninstalling the mod.
Phone migration may use local backup files, manufacturer transfer tools, or manual exports—none of which guarantee parity with your old GB install. Back up on the old device before wiping it.
If backup failed because the app crashes or will not open, fix stability under Troubleshooting first. If you were forced off the mod by a restriction, read Account & Security before repeated login attempts on a new install.
