After developer Brightiup released their information about a brand new kernel vulnerability, another developer, BinaryBoy made a full kernel exploit out of it which can be used to update both Unc0ver and Taurine Jailbreak. The exploit compatibility is from iOS 15.0 up to iOS 15.1.1 and iOS 15.2 Beta 1, however, if you missed the opportunity to upgrade or downgrade, it may be too late.
Reports in the community show that the OTA Delay method may or may not work. It’s certain that the traditional OTA Delay method won’t work at all to update to iOS 15.1 / 15.1.1, but it may still be possible to do it if you are jailbroken on a lower version and use tweaks to do the update. There are reports Apple Configurator may work too, but you need macOS for that.
