3. Through Filza we go along the path System / Libraries / Coreservices. Copy the SystemVersion.plist file to the same folder. The file will be called SystemVersion (1) .plist
4. Open SystemVersion.plist, find ProductBuildVersion. Change the value of ProductBuildVersion to 17D50. Then we return and in ProductVersion we change the value to 13.3.1. Click save and done.
5. We reboot the device with the buttons. The download will be long, with a running status bar.
6. After loading the device, insert the sandwich and enter the current ICCID in the drop-down menu.
7. We go through the activation and we have a fully functioning device. (will not work without a gasket)
Now return the firmware version:
1. We take the phone, again we put the jail checkrain 0.9.8.2.
2. Thanks to the Apple File Conduit “2” tweak installed earlier, we connect the phone to any program (iTools, 3Utools, etc.) and go to the “File System” section.
3. In 3Utools, as an example, we go along the path System / Libraries / Coreservices. Delete the SystemVersion.plist file and rename the previously copied source file named SystemVersion (1) .plist to SystemVersion.plist. That is, without "(1)".
4. We reboot the device with the buttons. The download will be long, with a running status bar.

That's all. The phone remains on the old firmware 12.4.x and works as a non-wizard. After all the manipulations, all applications work stably, both old and just installed.

can u give us any video link ?
