SHSH2 Blobs Errors [FAQ]

Having problems verifying your SHSH2 blobs, here are some frequently asked questions (FAQ).

Q. Can I use this tool on my iPhone? I am not on my PC at the moment.

A. Yes. Just make sure your blobs are backed up on Dropbox/Google Drive and you’ll be good to go.

Q. There are a lot of files in the folder where my shsh2 blobs are backed up. Do I need to verify all files?

A. No, there’s no need to do that. If one of them is valid then all of them are valid. It’s as simple as that :).

Q. TSS Saver website says “rosi tag” not found. Are my shsh blobs corrupt?
