2 years ago Hello, I am back with good news. I finally managed to fix the "Unable to Activate" issue. I'm going to explain how I'm doing it to help as many people as possible. First of all, I'm sure MacOS and I have an IPhone 8 GSM under iOS 15.6 RC version, this version is still currently signed so very easy to downgrade. I used my iOS 16.0.3 blobs because I have a bug with saving 15.6 RC blobs. In the folder, edit the text file 'sunst0rm.py' and on line 187 add this: --custom-latest-beta', '--custom-latest-buildid', '19G69'. Then you need to install the sunst0rm dependencies and everything else, you can use the guide on the GitHub or on YouTube. Subsequently, I used GASTER to put my iPhone in PWNDFU after having put it in DFU manually. Finally, enter the script with the blobs and the ipsw you want, for me it's version 14.3. After entering the 2nd script (the one with the identifier), put your device in DFU mode manually and reuse GASTER. Finally, use the boot.sh script and enjoy your new version. I'm not a professional, I just followed a lot of tutorials and asked for help. Personally, I reinstalled the latest version of IOS on my phone while waiting for the developers to manage or not to fix the microphone and speaker problems.
Hello, i have an iphone 8 (gsm) and when i downgrade with Sunst0rm on 15.7 to 14.3 or other versions. After the downgrade complete, when I open welcome menu on iPhone, I get an error message "Unable to activate". I tried to change the shsh blobs file, change the pwndfu mode (gaster and ipwndfu), try to activate the iPhone in Finder but nothing works. Any fix please ? Im on macOS
