Checkra1n v0.9 beta now available for public testing

Following several weeks’ worth of electrifying teasers, hacker Luca Todesco officially unveiled checkra1n, a brand-new jailbreak utility based on @axi0mX’s new checkm8 bootrom exploit for A5-A11 devices. Todesco presented the new jailbreak after taking the stage at POC2019 in Seoul, South Korea on Friday, just as he said he would, but subtle issues delayed the original launch expectation by a few days.

Checkra1n is a precedent-setting jailbreak the likes of which we have not seen since limera1n on the A4-equipped iPhone 4. Checkra1n isn’t untethered like limera1n was, but it utilizes an exploit that can’t be patched by Apple with any traditional software update, which commendably means that impacted handsets can be jailbroken for life regardless of software version.
