  1. Buddy, I even tried hard reset but it’s not working. I am still getting the same error code while installing wptorrent. Please help!!!!

  2. Hi. Thanks for the article. I’m facing same error and have tried first three methods which unfortunately didn’t work. So I will be resetting the phone now, before which I just want to make sure whether it will solve the error for sure.

  3. I’ve been using Android-based devices since the beginning, never had a single problem, now I’m forced to use a Lumia shitty device, EVERYTHING needs assistance, there is no one around capable to solve anything, every time I have problems of compatibility between this phone and its very own applications, i’m not talking about foreign apps, I’M JUST TALKING ABOUT WINDOWS PHONE BASED FREAKING APPS!!!!!! Wake up people, it can’t be true, a device not connecting with ***ANY*** of the apps expressively created for it BECAUSE simply it’s UNABLE to do that, no wifi problem whatsoever with all the other devices in my home, only THIS SHIT branded Microsoft still has problems. I wish everyone of you to wake up from the dead and finally THROW those devices in the trash can, I do hope these failures on the market will disappear as soon as possible, for me it’s only another day WITHOUT conectivity on my phone, I will toss it into the river just to get ANOTHER android device very very soon….

  4. My wife and I both have this issue on Lumia 920s when trying to update OneDrive. The first three solutions above all fail to resolve the issue. I haven’t tried a full reset of the phone yet because when I try to back up, that fails, saying I need to update OneDrive!

    I reported the issue to OneDrive Help and had a short email exchange with them. They have now supposedly escalated the issue.

    1. Suggestion from mr. SlyFoxNL (not me)

      Go to: ‘’
      Sign in
      Click on ‘Your info’
      Click on ‘Manage how you sign in to Microsoft’
      Change primary alias (if you don’t have one, make one and change primary alias)
      You can try to reach again 🙂
      I HOPE this will work for more people than only me!!! 🙂

  5. Ugghhh none of the solutions mentioned above worked out for me.
    All other apps are getting installed except whatsapp…none of the solutions could resolve it. 🙁
