iOS 9.3 – New Firmware Manager Version | Tethered Boot and Translation & BUG Fixes

The new Firmware Manager, code-named Milan 9.0 comes with a lot of BUG fixes, visual improvements, and the brand new Tethered BOOT for Tethered Jailbreak or Tethered Downgrades (A4 Devices).
The system for tethered boot is based upon OpenSn0w, a creation of @winocm and is only compatible with A4 (limera1n exploitable devices).
Now you can send translations for your own language and I will update the app 🙂
As usual, you can use this app to decrypt, encrypt and build DMGs inside the IPSW, using appropriate keys.

Here is our description of the app we've built. You can find this one on The iPhone Wiki:

The application comes as a faster access route for the old CLI applications like xpwntool and libimobiledevice project. The application's main purpose is to bring access on CLI applications for firmware DMG Encryption / Decryption, ASR patching and restoring for persons that doesn't understand CLI applications.

This application is currently running on Windows only and requires .NET Framework installed on your computer to be able to run. Unlike other Firmware restore / Modify tools, F.C.E. 365 Firmware Manager does not need iTunes to be installed.

Basically, the app uses xpwntool and especially dmg.exe to Decrypt the ROOT FS DMG file inside the .IPSW Firmware using appropriate Firmware Keys, then using the same keys it encrypts back your modified ROOT File System DMG. The same thing applies to ramdisk DMGs inside the IPSW Firmware. The application uses hfsplus to decrypt the ramdisk and allows you to create the patches for ASR, iBSS, iBEC and so on.

F.C.E. 365 Firmware Manager makes use of libimobiledevice, especially of idevicerestore CLI to restore an iPSW for your iDevice. The device selection is made by UDID and the restore options are: Erase Restore, Update Restore, Custom Restore, and Restore Latest Available. Due to libimobiledevice integration, this app does not require iTunes to restore the iPSW. SHSH Blobs are also fetched automatically by idevicerestore.

This app includes a tool for getting the phone out of Recovery Mode with one click. You can also put the iDevice into Recovery Mode with one single button! It also makes use of ideviceinfo to query all information about your device whenever you need it.

Using libimobiledevice, this application is able to query all information about the connected device, such as UDID, IMEI, WLAN Address, IDs, Settings, Activation status, Serials, Sim Status, Baseband, Versions of iBOOT, Baseband, iOS etc.

It also include a tool that brings you to Apple's official Activation Status Check page. You can check here the IMEI or Serial Number to make sure the iDevice you are buying is not iCloud locked!

Using the application you can also decrypt and patch all IMG3 files (like iBOOT, RecoveryMode, LLB, AppleLogo, etc.), DFU Files (iBEC, iBSS), KernelCache file and ASR.

The backup function allows you to create independent backups that does not interfere with iTunes ones so you can study the iOS backup system, trigger iOS hidden features by editing PLISTS and study potential exploits or glitches.
