Done 😄

This will likely happen again it seems, so when it does... get the memory dump with the STLinkV2 like the first time if DFU mode is inaccessible. It will be helpful to see if it's failing the same way as before.

Will Do… For sure…

I am learning how to build locally so I don’t need to bother you with the wand 😊

Bad things happen for a reason.\> The reason today is I am learning something new!!

Thanks for the help!

EDIT: Quick question @BDub: Would I still need the magic wand if I build my own firmware locally and program using the STK-LINK target?

If you have claimed your device, uou can also refresh the keys yourself:

First create a key - this is only needed the first time. Subsequent times can reuse the same key:

```auto
particle keys new

```

Then send the key to the cloud:

```auto
particle keys send <device_id> device.pub.pem

```

Then you’re all set with your own magic wand!
