Meshtastic uses the [littlefs](https://github.com/littlefs-project/littlefs) library to store configuration, logs, and other data in the internal flash of nRF52 & RP2040 devices. Updating the firmware does _not_ erase this additional data, which can cause issues when the format and location of data changes between releases.

You may now use the [Meshtastic Web Flasher](https://flasher.meshtastic.org) to Factory Erase your nRF52 or RP2040-based devices. Visit the flasher, select your board, and click the trash can icon to the right of the Flash button. This will open a dialogue to begin the erase procedure.

|
Alternatively, follow the instructions below.

To reset the flash storage on your nRF52 board:
|
|
|
|
1. Download and unzip the latest firmware from [Meshtastic Downloads](https://meshtastic.org/downloads).
|
|
2. Connect your device to your computer with a USB data cable.
|
|
3. Double click the reset button on your device (this will put it into bootloader mode)
|
|
4. Notice a new drive will be mounted on your computer (Windows, Mac, or Linux)
|
|
5. Open this drive and you should see three files: `CURRENT.UF2`, `INDEX.HTM`, and `INFO_UF2.TXT`
|
|
6. Find the file included in the downloaded firmware named `Meshtastic_nRF52_factory_erase.uf2` and copy it onto the new drive. The device should reboot.
|
|
7. With the [Meshtastic CLI](/docs/software/python/cli/) installed, open your Terminal/Console and enter the command: `meshtastic --noproto`.
|
|
8. Press any key, you should see the message: `Formatting... Done`.
|

|
|
