a GUI macOS app to downgrade compatible A6 and A7 devices to OTA signed firmwares.

• Latest compiled version can be found here.
• Official LeetDown Twitter account for updates & support.
• Official LeetDown webpage

LeetDown is not compatible with virtual machines. Some hackintosh systems were successful running LeetDown, though, exploiting issues you encounter on environments other than real Mac hardware is up to you to resolve. Please do not open an issue for this.

• Due to the USB stack of ASi macs, the device will disappear after LeetDown uploads iBSS. When you get the prompt [+] Device was lost, reconnect the USB cable to your mac to resume the upload process, do what it says and the restore will resume automatically.
• Make sure to reconnect the cable to your mac. You don't need to replug the cable to your iOS device.

• Make sure you're not using any USB Hubs or type-c to lightning cables. If your mac has only USB-C ports, use a lightning to type-a cable with a USB type-c to type-a converter.
• Make sure you're not running LeetDown under a virtual machine. Check compatiblity here.
• Re-enter DFU mode and try exploiting again with LeetDown.
• If it's still not working, download iPwnder-lite and exploit your device manually.

• Update to latest iOS version with iTunes/Finder/idevicerestore then try again.
• Check if your USB cable is working fine.
• Try with a different USB port (or adapter if running on Apple Silicon).

Mount the LeetDown_[VERSION].dmg and drag the LeetDown.app to your /Applications folder.

Follow the instructions shown in the app.

LeetDown depends on the following libraries:

• libcrypto (get it via brew install openssl)
• libirecovery
• libplist
• libusb (get it via brew install libusb)
• libusbmuxd
  ps: If you don't want to compile libirecovery, libplist and libusbmuxd manually, Nikias Bassen has a script available that can build all libimobiledevice tools automatically.

Place the libraries in any folder (preferably inside "Frameworks" to build it statically) in your environment, then;

• Project -> Build Settings -> Library Search Paths -> path_to_your_folder

LeetDown depends on the following frameworks:

• AFNetworking
• SSZipArchive

You can install them automatically with cocoapods.
Note: A modified version of SSZipArchive is already placed inside the project, skip installing it via pods.

• Enable debugging by clicking the box in LeetDown's settings.
• Open an issue, fill the template and attach the LDLog.txt to it from your ~/Documents folder
