Revision as of 23:37, 10 October 2010

This is geohot's jailbreak utility. It uses his undisclosed exploit, along with comex's userland exploit, to achieve an untethered jailbreak on newer devices.

It has been demonstrated multiple times by geohot, using blog posts on his now private blog. Geohot showed off a high-res picture of Cydia on an iPhone 4. He displayed an iPod touch 3G with an untethered jailbreak that met MuscleNerd's requirements for a good video. In addition, he took a picture of Cydia and blackra1n icons on his iPad's SpringBoard.

limera1n beta 1 was released on October 9, 2010, delaying the release of greenpois0n, because greenpois0n has to be rewritten to use the limera1n exploit instead of SHAtter. It only supports Windows at the moment and some devices have issues.

Technical Information

Basics

Exploits

limera1n uses an undisclosed bootrom exploit.

Process

The jailbreak appears to execute something like the following (in no particular order): 

"setenv debug-uarts 1
setenv auto-boot false
saveenv"

Controversy

The release of this jailbreak is specifically designed to pressure Chronic Dev into implementing the exploits in limera1n into greenpois0n. Now that geohot has released limera1n, SHAtter can't be released, as this would burn another bootrom exploit.
