I solved the problem.


1. enter 'App Store' app.

User uploaded file

2. try to log-in with your ID which is called X at the App Store app.

3. You can see a different Apple ID in the App Store id section after the 'could not sign in'. I will call the ID as Y.

4. press home button.

5. enter 'settings'-'iTunes and App store'.

6. log in with Y id and Y password at the Apple ID. You have to know the Y password.

7. tap Apple ID and logout.

8. log in with X id and X password at the Apple ID.


It works for me.

I’m on an iPod 6th gen and just updated to iOS 11.0.2 after having this issue on the previous version, I’ve literally spent over 8 hours trying to fix this but to no avail, can’t download anything, lost all of my music and can’t download anymore/anything else because when I try to sign in I get stuck in an endless loop. So frikin mad I’ve almost thrown this thing into a wall. (Date is 10/8/17 for future reference)
