Semaphorin uses mineek/seprmvr64 (github.com) to tether downgrade your device without blobs by patching out sep
Official repo:
I should first start off by saying, thank you Mineek, LukeZGD, and TheRealClarity for all your help in the development of this project. It is greatly appreciated, and a lot of this would have not been possible without you. Mad respect.
We released this project a few months ago on Reddit, and it ended up being a flop due to endless bugs it had at the time. So, between then and now, we spent countless hours working out all the bugs and adding new features.
This is a checkm8 downgrade tool that allows you to, as of now, tether downgrade any a7-a11 device to just about any version of iOS without any need for blobs. This includes devices that are running iOS 16 or 17 prior to downgrade. Yes, you heard that right, we now support iPhone 8, 8+, and iPhone X as well as devices running iOS 16 or 17.
We made release posts for semaphorin in the past, but those were betas and were plagued with bugs. we have spend countless hours fixing all the bugs with semaphorin. if you have any issues you can reach out to me on discord, my username is ka7hrtp
Some of the most notably changes
- You can now downgrade even if your device is running iOS 16 or later prior to downgrade
- We now support a10x and a11 devices in addition to a7-a10 devices
- Camera, photos apps are fixed
- Usb related issues have been addressed, especially for a7 devices
- iOS 9 support, even for a9 devices, including the iPhone 6s and iPhone SE
- iOS 8 support for a8 devices, including the iPhone 6
That is just a few of hundreds of changes from the last reddit post we made until now
Please avoid using the gui version of Semaphorin!! It is for demonstration purposes only, and can be especially hard to use on devices running iOS 16 or later prior to downgrade. You should use the terminal version instead. If you are reaching out to us for support, do expect to be told to switch to the terminal version if you were using the gui. Thank you for your patience and understanding.
How do I use this?
This script deletes everything on your phone, including the main OS if you are not downgrading to iOS 10.3.3 or later. Make sure to backup all of your data before using this script as **anything on the device prior to running this script will be unrecoverable afterwards**. Use this script at your own risk. We are not responsible for any damages caused by you using this script.
To use this app, you need to downgrade to a supported version, and have a supported device.
xcode-select install to install git on macos
git clone && cd Semaphorin
Connect device in DFU mode
sudo ./semaphorin.sh --restore
For example you may write sudo ./semaphorin.sh 9.3 --restore
The script has to backup important files from your current iOS version before you can downgrade.
When the script asks [\*] Please enter the iOS version that is currently installed on your device., type your current iOS version and then hit the Enter key to continue.
It should then begin the process of downgrading your device. Please follow the on screen instructions. This might take a while. Your device will reboot multiple times.
Subsequent runs after downgrade is finished
Connect device in DFU mode
sudo ./semaphorin.sh --boot
For example, if you downgraded to iOS 9.3, you would run sudo ./semaphorin.sh 9.3 --boot.
It should just boot to your requested iOS version normally.
