Downgrade without SHSHĪn untethered downgrade requires a BootROM exploit, which is very valuable and difficult to develop.Įven if a hacker releases such an exploit publicly, it will only be useful for 32-bit devices.Ħ4-bit devices require a much powerful exploit for downgrading because they have SEP firmware to take care of. This seems somewhat plausible because an iBoot exploit is relatively easier to build. How can this prove useful? Untethered jailbreak for iOS 9Īn iBoot exploit could potentially lead to an untethered jailbreak for the affected iOS 9 versions. As far as the device-specific code goes, there are identifiers present for iPhone 6s/6s plus, and iPhone SE. This source code pertains to a specific build of iOS 9 firmware (9.3.x).

It also includes a “Documents” section, which provides a lot of in-depth information on how various components work.

This version is missing a few files that were present in the original leak. The source code package titled iBoot_BootROM_iBSS_iBSS_iLLB_Source_Codes.rar is available for download publicly below. It has been in the public domain for about 4 months. Q3hardcore leaks BootROM and iBoot source codesĪ Twitter user who goes by the name, q3hardcore, recently leaked Apple’s classified internal code online.Įarlier, this code was shared by developers in private and even sold by some before it was leaked.
