Bluebomb is an exploit for Broadcom's Bluetooth stack used in the Nintendo Wii. The main benefit of it is that it can be used on the Wii Mini, which lacks functionality used by other exploits. It can also be used to recover from Banner bricks. It takes advantage of the Wii's Bluetooth and injects unsigned code into the system via Bluetooth.
Installation requires a computer that can use Bluetooth, and a Linux operating system. Here is a guide to help you with the exploit: https://wii.guide/bluebomb
