If you have TinyUmbrella, things are different because this incredible little tool can pull your device right out of recovery mode without changing anything – all your data and your settings will remain intact. Regardless of the reason why your device is in recovery mode, getting stuck in it is not what you want because the only way out of it is a complete restore and that means losing everything (although you backed it all up first, right?) We’re not finished yet Fixing a Device In Recovery Mode:
SHSH blobs come in three types – OTA, Update (Restore) and Erase (Restore).known_devices is used to store details of all known details TinyUmbrella saves your SHSH blobs in a file named ~/.tu.That’s why you should get into the habit of using TinyUmbrella as soon as you update your device – every time. If you have an older iOS firmware that isn’t being signed anymore, the blobs cant be saved. TinyUmbrella can only save blobs for a firmware that Apple is still signing. Once the tool has detected your iPhone or iPad, it will automatically look for SHSH blobs on your device and will save them all to an external file.If not, unplug your device, shut down the app and then try again. Launch the app and make sure your device is detected.
