Updating to 12.5.7
For support in English, ask for help on the r/Jailbreak Discord Server.
Required Reading
Unfortunately, there is currently no jailbreak available for firmware version 8.0 to 8.4.1 on 64-bit devices. However, some devices, such as the iPhone 6, can update to 12.5.7 and use the Chimera jailbreak instead.
This is achieved by simply updating through the Settings application normally. Because the latest available version for these devices is 12.5.7, we can easily update to this firmware version.
If you have installed update blocking via tvOS Beta profiles, you must first remove that profile before updating. If you don't know what this means, ignore this.
