- The jailbreak option **might not work** on A5 Rev A devices (see issue [#70](https://github.com/LukeZGD/iOS-OTA-Downgrader/issues/70))
- For users that downgraded **without** jailbreak option, and have manually jailbroken with the EtasonJB app, it is recommended to install "EtasonJB Disable Bootloop Protection" from my Cydia repo
