This message only appears for WiFi modules <b><u>if unlaunch is NOT installed</u></b>. If you have unlaunch, look at this alternative:<br><br>
- <a href="../../pages/nand/title_overflow.html">Title overflows</a> can also cause a similar looking error

<h3>Description</h3>
The DSi immediately boots to "an error has occurred."
<br><br>
This can happen if the installed WiFi module and firmware are incompatible.
<h3>Solution</h3>
If you have the DWM-W015 WiFi module, the error is caused by something else. The DWM-W015 version is compatible with all firmwares.
<br><br>
If you have the DWM-W024 or J27H020 WiFi modules, you will need to either replace them with a DWM-W015 or upgrade your firmware to v1.4 or higher. These boards are not compatible with anything prior to v1.4.
<br><br>
The WiFi module types are shown below. From top to bottom: DWM-W015, DWM-W024, J27H020
