In today's video I have something very important to show you. How to save the SHSH2 Blobs from your device to be able to use them with Prometheus in the future. Prometheus is an upcoming downgrade tool for all arm64 devices, but it requires saved blobs to work and not any type of blobs, the new format which is SHSH2.
SHSH Blobs are only generated by Apple Servers IF they sign the specific version; if not, you won't be able to downgrade and therefore you will be forced to stay to a non Jailbroken latest version. By saving and taking care of the SHSH files you are able to use Downgrading tools like Prometheus to downgrade at any time to iOS 10.1.1 (which is now jailbroken) or whatever version you save blobs for.
WARNING! You can only save the blobs while the version is still signed so do it NOW!
