RedSn0w 0.9.15b1 was a gargantuan update. In fact, we're still trudging through all of the new features. One new addition that has us really excited is the new direct restore option for pre-A5 devices.
This new restore option allows you to downgrade your device without having to fool with host files, stitching, Pwned DFU, iTunes, or anything else that made downgrading so incredibly cumbersome in the past.
We've made a step-by-step tutorial that shows you how to use this new restore feature, along with getting by those pesky Mismatched APTicket errors. Check inside for the full tutorial.
