Previously/related: Hacking the Xbox 360 Hypervisor Part 2: The Bad Update Exploit - https://news.ycombinator.com/item?id=43244739 - March 2025 (107 comments) Hacking the Xbox 360 Hypervisor Part 1: System Overview - https://news.ycombinator.com/item?id=43167163 - February 2025 (0 comments) Apparently there has been a lot of development to improve the speed and reliability/repeatability of the exploit, as at this time it is not persistent (it must be run every time the console is booted). Modern Vintage Gamer was able to get it to run 10/10 times in a row under a minute each time, from what I can tell, which I love to see.

Yeah, I remember finding a good supply of Verbatim DVD+/-Rs and +RWs, and iirc the -Rs seemed to work better for my particular stock internal optical drive, and a slow burn speed was key. Once I got FTP setup to my desktop and sorted out the FATX situation, I upgraded my internal HDD and didn't really mess with disc-based backups for 360 as it didn't seem worth the hassle once I got it ironed out, which I'll admit was a decently complex project involving hot-swapping, but not much more complicated than the initial drive firmware flash. They're fun machines to mod, especially as I had just finished an OG Xbox softmod project at the time (~2007). Edit: This might be relevant to your interests, and to others interested in 360 modding. https://github.com/grimdoomer/Xbox360BadUpdate > Bad Update is a non-persistent software only hypervisor exp

loit for Xbox 360 that works on the latest (17559) software version. This repository contains the exploit files that can be used on an Xbox 360 console to run unsigned code. Addendum: Modern Vintage Gamer's video of the exploit, which is amazing to see. I had no idea 360 softmods were a thing, and the exploit can run against a free trial version of a retail game, which is just chef's kiss. https://www.youtube.com/watch?v=ycY09EUm8wA > Any Xbox 360 can now be hacked in less than one minute > A look a the newest V1.2 Badupdate Exploit - Xbox 360 software only Hypervisor Hack that we covered back in March 2025. It requires an Xbox 360 - any model including the later Winchester revisions! A USB flash drive and Rock Band Blitz Trial. This updated 1.2 hack runs much faster and reliable and is now a recommended option to hack any Xbox 360. In today's episode we take a closer look at the BadUpdate V1.2 exploit.
