Among its various features, ReRa1n allows users to downgrade their iPhone and iPad easily. If you are using an iPhone or iPad equipped with an A5 to A11 processor, you can now downgrade your iPhone to any firmware.

If you do not have a Mac computer for the downgrade, then the ReRa1n tool will help you to downgrade your iPhone / iPad without SHSH with Windows and Linux.

I have tried this many times in windows, ubuntu and macos x high sierra without any success. Not one time has it shown a restart ReRa1n window and when I get to the options window and choose SSH (3) it says connecting to device….command not found…successfully exited ssh window or it says connect to host localhost port 2222: Connection refused. So the title is misleading as I have found nothing easy about downgrading an IOS device.
