Markus “Doom” Gaasedelen has showcased a “Bliss” exploit that jailbreaks the original Xbox One console, presented at RE//verse 2026. The method requires soldering a microcontroller to the motherboard and removing capacitors. It affects only the initial model, leaving Xbox One S and X unaffected.
The Xbox One launched on November 22, 2013, and was long regarded as “unhackable,” unlike the PlayStation 4, which was jailbroken by 2016. Gaasedelen’s demonstration marks the first major breach after 12 years, as reported via Tom’s Hardware coverage of RE//verse 2026, published March 16, 2026, by Kotaku. The process involves hardware modifications: attaching a microcontroller to the motherboard and adjusting voltage by removing capacitors, making it more complex than PS4 jailbreaking methods like burning a Blu-ray or using an Ethernet cable. Microsoft cannot patch this via firmware updates. This development holds significance for preservationists, enabling full game decryption—beyond what the Xbox One Developer Mode subscription, available since 2016, permitted for apps and emulators. Modern Vintage Gamer noted that Dev Mode likely reduced hacking incentives by allowing emulator installations. The exploit applies solely to original Xbox One units; Xbox One S and X remain secure.
