How to Fix Error Code 805a8011 in Windows Phones

Although Microsoft has quit phone business by now, many people still use Windows Phone devices. Some developers even continue to support their apps, regularly update them and even develop new features. If you are that kind of user, who refuses to give up on Windows Phone yet, you may face error 805a8011 in the Windows Store (on Windows 10 Mobile it is called Microsoft Store). This error shows that there is a synchronization issue with your device and Microsoft Account. It can also cripple other applications that use Microsoft services and your account. Here is how to fix error 805a8011.


How to Solve Error 805a8011 on Windows Phone?

Before you start, make sure you have a reliable Internet connection. Bad Wi-Fi or cellular might be actually the reason why you can’t download or update an app from Windows Store because of error 805a8011. If the Internet connection is fine, follow the steps below.

Error 805a8011 – Account Synchronization Problems

Go to the Settings on your Phone and open Email and accounts section. Tap Microsoft Account. You might find there an error message. If so, the root of the problem is found.

Press and hold your Microsoft Account and tap on Sync button in the menu. Make sure the error message is gone and try to download an app from Windows Store again.

Some users report that filling up all Microsoft Account information on the (credit card, billing address, etc.) might help you solve the issue. Open, log in with your account, fill up everything Microsoft requires, and sync Microsoft Account on your phone again.

Error 805a8011 – Incorrect date and time

If manual sync did not help you or synchronization error appeared again, check date and time in the Settings. Perhaps, your phone has the wrong date and time settings, thus can’t connect to the Microsoft Servers. This is one of the most popular reason, why error 805a8011 or sync issues happen on Windows Phone devices. Set up time, date and time zone manually, restart your phone and try to download or update an app from Windows Store again.

Error 805a8011 – Soft-reset

If that did not help you either, perform soft-reset. Don’t worry, soft-reset won’t wipe any data on your device. Here is how to do a soft-reset on a Windows Phone: hold the Volume Down and Power button together for 15 seconds and wait until device restarts. Soft-reset can fix a random bug that causes error 805a8011.

A few other tips to consider:

Never allow your phone to work with the filled up to the last byte storage. If your device has little storage space, delete some data to free at least 300-500 MB. In order to operate normally and without nasty errors, Windows Phone constantly needs some free space. Consider buying SD card (if your phone has a microSD card slot) or move some data to the cloud.

Hard-reset. If nothing above worked, try to wipe your phone and set it up from scratch. Be sure to backup important data before you start.

Open Settings – About and press Reset your phone. Confirm your decision and wait until the phone boots back. While setting up your phone make sure you have reliable Internet Connection, correct date, and time settings, and entered correct Microsoft Account credentials.

One more thing:

Sometimes there is no fault in your account or device settings, but the error 805a8011 simply refuses to go. If you tried everything including hard-reset but had no luck and error 805a8011 still bugs you, sit back and wait. Probably the issue is on the Microsoft side and it will disappear in a couple of hours or days. Yes, using a device without your apps and clean storage may be really frustrating, but that is the reality of using a smartphone with an outdated operating system. Windows Phone and Windows Mobile are dead nowadays, thus servers can go offline anytime, and you won’t be able to do anything with that. Whether you like it or not, perhaps it’s time to buy a more modern device.

  25. This mobile phone like having its own brain & needs. Whatever I did, didn’t work. Before I go on reset, I’ll continue erasing photos from phone memory, hoping that will work. As HE acting very weird. I think somethings very wrong with this phones guys. You don’t find it strange how suddenly all Lumias start to showing low memory and after ignoring that start to showing you error 805a8011?! To me this is enough of us to send to microsoft LARGE mail of how zthey fuck us up! They cant find this okay and selling to us mobile phones which will start to showing errors few months after we no longer could reclamate phone to distributer?! For me..when I came and saw how much of us have the same problem…oh man, I am so mad I could throw this mobile phone to a face of who ever is responsible for this crap here I am dealing with for a 3months. And only way to deal it is RESET. Don’t listen to this guy..because I girst think he want to help..but he is here only to wash our eyes lile there was solution other than reset. This OTHER solutions didn’t help anyone here! Noone. Omg..I am so sad/mad!

  26. Microsoft is really playing with our minds…we have been loyal customers of this phone but ts frustrating now….PLEASE FIND A REAL SOLUTION BEFORE PEOPLE START SUING

  27. The error 805a8011 is the most frustrating thing about the Lumia 520. Shame on Nokia for betraying our trust in their products.

  28. why is it that my htc 8x while updating to windows 8.1it stops on the way and shows an error……..
    …..i have tried to out many things but there is some stuff known as the preview for developers ………..i have tried and tried to login to it but it says am not a developer ……and i have also tried to create to Create a student developer account but its still the same it stops on entering verifications

    so i was kind of asking for you help any one with a developer account to temporally help me with it for a mean while ……….i will be grateful if u guys do so

  29. For anyone that comes across this article, these steps could work for you, sure, but let’s be real here: Windows Phone is an abandoned and now obsolete OS. No matter how much we want it to keep working, there will be a moment when servers are taken down and the phone will be unusable.
    It’s sad to see it go of course, this OS lacked in some areas but in others I’m confident to say it surpassed Android and iPhone. Its interface was slick and quick, apps didn’t keep on running in the background when you closed them, the store had some great apps you can’t find on any other store. It was a failure and the fault rests entirely on Microsoft. They completely abandoned it. Windows 10 mobile was a huge disappointment, riddled with bugs with a store even more devoid of apps. Half the phones on the market couldn’t update to it. And when they declared the OS dead, they were still selling phones that had it! A total scam.
    Myself, I tried every step this article explains and even more. The only step I didn’t try was making a hard reset. Why? Because there’s two big problems with that: 1. the backup could get stuck on a percentage making it unable to save any important data to restore later (this has happened to some commenters and to me as well), 2. in case the backup is successful, it would not backup your installed apps, and if the store error still persists, it would be unable to reinstall the apps because it doesn’t have access to the store. This is even worse if the apps you were using didn’t have a Cloud option. You’d have a phone with no apps whatsoever, only the ones preinstalled.
    Advice? Switch to Android or iPhone. There’s no other choice because the support will stop, the servers will be taken down, and this error will not be fixable anymore, if it even is fixable now.
    The OS it’s still somewhat usable. I can’t update my apps, (like Whatsapp, Telegram, etc.) because I don’t have access to the store, but I can still use them. So keep using your Windows Phone if you like, if you feel more comfortable with it. But don’t keep it as your main phone, or at least have a backup one, because the support for the OS and for the apps will stop, and it will render the phone useless.

  30. I’m getting the same error code (805a8011) when I try to open the store. According to all the comments above I understand that nothing seems to work, but it would be great if someone here could let me know an alternative way to update my whatsapp. My primary concern is to back up my whatsapp data. So if anyone has any idea about either updating whatsapp without the store or backup whatsapp data (using a PC, tool or anything), or get this store’s issue sorted.

    Note: I want a backup of my whatsapp but my whatsapp’s current version has expired. to update the same I need windows store to work but the store is betraying me with this code.
