Still stuck on the aging iOS 8? Well, it’s time to update to iOS 10.2 now and jailbreak it. Here’s how to do it.
We will be using Tihmstar’s Prometheus utility to perform the upgrade. Before you begin the upgrade process, you must first enable tfp0 patch on Pangu8 jailbreak.
You must upgrade quickly before Apple stops signing iOS 10.3.1. This will ensure your TouchID remains intact because iOS 10.3.1 SEP is compatible with iOS 10.2.
Just like all other tools, Prometheus requires valid SHSH blobs. This tutorial will be useless if you don’t have valid SHSH blobs.
SHSH blobs are what allow you to upgrade or downgrade to unsigned firmware versions.
Now onto the tutorial. Keep the following things ready beforehand.
