Coming back after a few months of not using any of my hacked apps so I was going through to reinstall updated versions as per usual. I had to reconnect my iPhone via iTunes and Sideloadly and everything but when it asks me to sign in with my Apple ID I get to the point of having to put in the security code that pops up on my phone and it comes back with "Unknown Error: Description not available (-22435)". I can click for it to send a code via SMS but nothing comes. I tried doing the Normal Install to get around having to use my Apple ID, but that just comes up with a different error saying it failed to install because "The identity used to sign the executable is no longer valid". When I looked up that one, it said this is usually caused by the date and time being wrong on the phone or the PC, but I've checked and everything is correct.
Tried a direct download from the iOSGods app onto my phone itself, but every app I try to install just gives me the "App could not be verified" pop-up as if it's revoked, even apps just updated 15 minutes ago.
I'm guessing all of these errors can't be happening naturally, so there must be an issue causing this to just not work in a myriad of ways, but I have no clue how to solve it.
