Can't sign in to the app store

Hi jelladlra,

I'm sorry to hear you are having these issues with your iPad. If you are having issues logging in or connecting to the iTunes Store, you may find the information and troubleshooting steps outlined in the following articles helpful:

Hi jelladlra and all,

I am a very early iPhone6 64GB onwer who experienced exactly the same problem than yours, few days after (but not right after) the iOS 8.3 update.

I experienced this problem few days before your post. As of now there are thousands of posts on the Internet about issues connecting to iTunes & App Store from an iPhone/iPad, but I was able to find less than 10 posts all over the Internet that might eventually correspond to my problem, and one post, Jelladlra's, that perfectly matches.

Logging to iCloud from my iPhone works perfectly with all of my 3 Apple ID's.

Logging to iTunes Store from my MacBook works perfectly with all of my 3 Apple ID's.

However, absolutely no way to login to the iTunes & App Store from my iPhone with any of my 3 Apple ID's. Absolutely nothing happens after login, besides that after pressing the "Sign In" blue-text-on-white-background-button, the blue text becomes gray then blue again.

I tried everything as Jelladlra, and anything else (I think) that can be done, including restoring my iPhone from a backup from another (working) iPhone. I also did the same thing the other way round! All my attemps failed but I could at least confirm the problem was my iPhone, and nothing else.

As a last resort I called the Apple Support. Sparing the details, the final answer was "your iPhone needs to be replaced; here are the options". I wanted to know more and I insisted to know the root cause and I was told what happened to my iPhone is "an electronic failure associated with the iOS update process" but that was as much as I could get as information.

Today I received a brand new iPhone6, just restored from backup, problem gone.

I am sorry Jelladlra for the bad news and I am interested to know more if anyone has anything to share.

The following is for Geeks only. The electronics failure answer is a difficult answer for me to swallow, but not impossible. After some Googling I found out rumors reporting that the first iPhone6 flash memories are TLC NAND type and have some reliability issues, whereas the more recent memories are MLC NAND type, faster and way more reliable. This is of course pure speculation but it might eventually explain:

Following app allows to know if you have TLC or MLC memory but unfortunately it does not work for iOS 8.3 at the time I'm writing this:

If you jailbrake you can connect as root through ssh and get to know your memory type:

Otherwise you need to open up your iPhone, look at the memory chip, Google the writing on it and get the memory datasheet.

Please let me know if anyone knows how to know the iPhone memory type without jailbreaking or opening the iPhone !

Cheers!

1. Replace "MLC NAND type, faster and way more reliable" with "MLC NAND type, slower and way more reliable".

2. I was finally able to determine that both the two iPhone's have the same MLC memory type, which obsoletes the previous speculation.

3. *** Big surprise: After the 3rd (THIRD) unplanned restore-from-a-backup attempt of the original problematic iPhone, the original problematic iPhone now perfectly fine and could connect to the iTunes App store right away and normally ***.

So Jelladra, you should connect your iPad to iTunes, back it up and restore it from the backup, and do this more than once. Let me know if it works.

This was driving me crazy too. I couldn't sign in or sign out. Trying to download an app prompted to login, and trying to login in the Settings for iTunes and App Store didn't work. I finally found another discussion that pointed me to the resolution I needed. I had to to into the iTunes Store on my iPhone (not the App Store) and sign out there. Once I did that, my account behaved properly and I was able to log into the App store and download updates and apps.

Try signing in to itunes from your computer and seeing if it asks you to verify your billing info. All I had to do was reenter my 3 digit security code for my CC info. After weeks of not being able to sign in on my device... finally works.

THIS WORKED THANKS SO MUCH

Guys like manonanytown said go to your computer sign into your account and then press on the music sign then press on iTunes and last of all verify ur billing info it will work!!!!!!!!

would you please explain the steps again for me

-Plug your ipad into your computer (I'm not sure if this is necessary, but mine was plugged in when I did it).

-Open iTunes on your computer.

-Sign in (at the top next to "search" box)

-Mine prompted me to update my billing info automatically, but I guess if it doesn't you can go to your account info and see if something is missing.

Hey jelladrla I was also suffering from same problem .... but after resetting my settings I was able to kill this problem... I think it might worked for u as well

Hi

I have the same issue and i have also tryed everything but it still didnt work. Were u able to find a solution

Hi all

Simple idea! Just go to your account and edit then CHANGE THE PASSWORD. I THINK THIS WILL HELP. ( From the PC).
