The term "'''failbreak'''" refers to a jailbreak that cannot be released to the general public, which makes it a fail to an extent. There are a [[#failbreaks|variety of reasons]] a jailbreak will become a "'''failbreak'''". This term came about when [[User:chpwn|chpwn]] showed a screenshot of his new [[iPhone 5]] running [[Cydia.app|Cydia]] shortly after its launch on [[Timeline|September 19, 2012]]. Shortly afterward, usage of this term picked up, and on October 19, 2012, [[User:Planetbeing|planetbeing]] tweeted that he upgraded the "failbreak" with a [[exploit|kernel exploit]] so that tweaks actually work on the [[iPhone 5]], to make it "almost a full tethered jailbreak."
 
This "'''failbreak'''" of sorts has existed for a while, since the iOS 4.0 days. If some of you will recall pod2g tweeted about a 2 year old exploit being closed, this is what he was referring to, the original "'''failbreak'''" being closed.
 
 
"This is actually not how we define "'''failbreak'''": pod2g heard us using the term in an IRC channel once, and then extrapolated the meaning; chpwn then had to clarify what he meant on a Twitter post, and now everyone is using the term in a way we usually do not, and the distinction is important, as people assume we have things we don't.
 
 
Specifically, a "'''failbreak'''"i s one that has malfunctioning kernel patches that prevent Substrate from operating. I provide a tool called "vmcheck" that people developing jailbreaks use to "unit test" their patches, and when it fails... well, that's a "'''failbreak'''". If you ran that tool on the jailbreak from chpwn/pheonix, that tool would fail.
 
 
The term was actually first used years ago by chpwn on a released jailbreak as there was something wrong with it that caused Substrate to only work in some processes; I was then later using it with regards to jailbreaks where the kernel patches didn't support the various memory protection changes required by C Substrate."
