Created an account here just to say that this worked for me.

I usually use 3utool to instal Phoenix 5.0 on my old ass iPad running iOS 9.3.5. However, 3Utools is giving me the error “jailbreak under maintenance”.

so I downloaded sideloadly and tried using that to side load a copy of Phoenix 5.0. I was getting the “unable to sign into Apple ID” even though all of the information was correct.

I simply went into iTunes, authorized my computer by logging in with that Apple ID, left iTunes open, opened iCloud and left it minimized, and retried installing Phoenix 5.0. It worked this time.

thanks for the tip. Hope other find this.

After a couple hours I make it to install Uncover on my iPhone 6 with iOS 12.5.4.

First, with my personal account I found the "guru error", after trying as many said, 20-30 times non-stop, it ask me for the 2FA code on my other devices. I think i made it. Then i got an erorr with something about serial number "XXXXXX". Some research tell me that i had to made another account.

With this temporal emails, and phone numbers, I made it to create it, try it again on sideloadly, try 20-30 times, and worked!!!

A had the same problem!

I opened my apple Apple ID settings and deleted all devices (an old iphone, ipad, PC) except my main iphone.

And in advanced settings, I selected "Remove limitations on supported devices"

It worked for me, maybe it will work for you

Same problem, but managed to make sideloadly back to "signing" by "REMOVING LIMITATION ON SUPPORTED DEVICE" in the advanced option in Sideloadly app.

had to re-enter my apple id login and asked me for 2FA on my other apple device. then it's working!

But it's taking longer than usual.

thank you for the tips!
