Note that there is a chance of bricking your console. In addition, this will
permanently break all wireless communications, and may prevent some games from running. I am not liable for any damage caused through this guide. By following this guide, you accept that you, and you alone, are responsible for anything that happens to your console.

+
Requirements
+
+ - Flashcart
+ - DS phat or DS lite
+ - Screwdriver or tinfoil
+ -
+ FlashMe
+ (I haven't tested this guide with flashme, but it should provide a layer of
+ brick protection)
+
+
+
Setup
+
+ -
+ Download the
040615 or 40820D prototype firmware.
+
+ -
+ There should be a
.bin file in your downloaded firmware. Extract it and rename it to
+ cfw.bin.
+
+ -
+ Create a folder on the root of your flashcart's SD card called
+
firmwares and copy cfw.bin to that.
+
+
+ -
+ Download
fwManager.zip* at the
+ bottom of this guide. (this is the tool we'll use to flash the firmware)
+
+ -
+ Extract
fwManager.nds from fwManager.zip and copy it to the
+ root of your flashcart's SD card.
+
+
+
Installation
+
+ -
+ Launch your flashcart on your DS, then run
fwManager.nds. Follow the
+ on screen instructions, but don't start writing to the console!
+
+ -
+ If you were start writing, you'd notice that nothing happens. This is
+ because the console memory is write protected. To disable it, open up the
+ battery cover. (see images in spoiler below)
+
+
+
+

+
+
WARNING: Make sure to not short a DS Lite (can happen by touching the metal
+ point right next toSL1). Use an improvised tool that is insulated to the
+ sides and only leaves metal exposed at the tip.
+ (thanks KleinesSinchen)
+
+ 3. Locate the SL1 pin. You'll notice there are two metal pads that make up the SL1. We need to bridge them (connect them together). This can be done by holding a small flathead screwdriver (or another metallic material) to both pads.
+
+
+
ANOTHER WARNING: DO NOT remove the battery at any time during writing. You will BRICK YOUR CONSOLE (see the green text below for unbricking)
+
+
+4. Once bridged, you may start writing. You must keep SL1 bridged for the
+entire writing process.
+
+5. When the writing is complete, unbridge SL1 and
+reboot the console.
+
+Your console should now boot to the prototype firmware (it
+may take a couple seconds to load). If your console does not boot after a long
+period of time, you've likely bricked it. But don't worry,
+
YOU CAN UNBRICK YOUR CONSOLE! Refer to
+
this blog entry for info on how to restore a bricked DS. It's pretty easy to do.
