TinyUmbrella

TinyUmbrella is a combination of two earlier tools, all of which were written by semaphore. It requires Java to be installed (Windows users need the 32-bit version, regardless of OS architecture).


 * Umbrella -- used to save the SHSH file of your iDevice to make it possible to later downgrade or restore the firmware. It even works with non-jailbroken devices.
 * TinyTSS -- local server used to playback saved SHSH files during an iTunes restore.

Quick Notes

 * For N90ap only, Tinyumbrella preserves the baseband (all versions)
 * Save SHSH -- If done with Request SHSH From Cydia ENABLED will result in Cydia storing your SHSHs for the current version Apple is signing.
 * If Cydia returns only some of the SHSHs you desired, it is because Cydia does not have the others. Sorry. Nothing you can do to get them.
 * TinyUmbrella needs admin privileges to listen on port 80 and to change your hosts file.
 * Mac Users -- Disable Web Sharing (System Prefs -> Sharing -> Uncheck Web Sharing)
 * Windows Users -- Disable IIS this may help Also make sure Apache is not running.
 * All users- Disable Skype while running TInyUmbrella
 * Make sure you have the latest java runtime installed Get Java (Click Download JRE)
 * Make sure you have iTunes installed. Rule of thumb: if your device is not detected in iTunes, it won't be detected in TinyUmbrella either.
 * Custom devices can be added by entering "Manual ECID"
 * AppleTV requires external power above and beyond what the USB provides. Please make sure your AppleTV is plugged into the wall. Then plug in the USB. Then reboot/reset your AppleTV. Then start TinyUmbrella.
