Issues When Upgrading from A Previous Version of Meshtastic​
info
Previous versions of the Meshtastic firmware may save stale data, causing devices to get stuck in a crash loop during startup. If you experience issues when upgrading your nRF52 device from a previous version of Meshtastic, you may need to perform a full factory reset of the internal flash memory.
Follow the guide to factory erase your nRF52 device before continuing to flash firmware.
