Thejailbreakcommunity has been anything but quiet lately. We’ve seen things ranging fromjailbreaking the new flagship iPhone XS Max, toupdating untethered bootrom exploits for the legacy iPhone 3GS, toreleasing a new jailbreak tool for firmware 1.1 on the original iPod touch; and now, something else of interest has surfaced.

In a curious video shared byYouTubeuser doras2 over the weekend, we discern what appears to be a fully-untetheredjailbreak running on a 32-bitiPhone 5handsetwith iOS 10.2.1 installedon it:

Upon booting up the handset, we see what seems to be a custom splash screen followed by the classic verbose boot (white text scrolling down a black screen) that might be nostalgically familiar to veteran jailbreakers. TheApplelogo later takes over the rest of the boot-up process before the device finally lands on theHome screen.

Right off the bat, you can see that a custom theme is applied to all the Home screenappicons. The YouTuber then goes intoSettings → General → Aboutto confirm the device identity andfirmwareversion, and then launches theCydiaapp to display even more compelling evidence.

Not much is known about the jailbreak at this time, but the video description describes a couple of details of interest:

The circumstances are rather curious, raising speculation about how it could be a one-off scenario in which only the iPhone 5 running iOS 10.2.1 is supported. Some rumors suggest how the jailbreak could also work on other device and firmware combinations, but this remains unconfirmed at this time.

From what we can tell, this jailbreak doesn’t rely on the user to side-load an app like most recently-releasedsemi-untethered jailbreaksdo. Instead, it’s a throwback to the olden days in which folks connected their handset to their computer to produce a jailbreak via aUSBconnection.

Notably, this seems to be a proof-of-concept jailbreak, so it’s unlikely that it will be released to the public. Nevertheless, it’s inspiring to see that untethered jailbreaks are indeed still possible despite the semi-untethered flavor of jailbreakswe’ve been using for the last several years.
