If you can't update your Flipper Zero via the qFlipper application or Flipper Mobile App, full or broken internal storage might be the cause. To resolve this issue, we recommend resetting your Flipper Zero to the factory settings.

Flipper Zero stores data on an inserted microSD card and internal storage. The internal storage has a small capacity and is used for storing the dolphin's level, settings, and information about paired devices. It also stores saved remotes and cards if a microSD card is not inserted. When you insert the microSD card, saved remotes and cards are moved from the internal storage to the microSD card.

On this page, you will learn how to back up your Flipper Zero, reset it to the factory settings, and restore it from a backup.
