If you forgot your Screen Password lock, if you want to erase your personal data, if you have a problem with applications, you can perform a Hard / Factory reset.

Resetting your phone will erase all content stored on your phone, including apps and games (along with app data and game progress), text messages, call history, music, photos and more.

Resetting your Windows Phone will return it to the state it was in the first time you turned it on. All of your personal content will be erased, and the phone will be restored to its factory settings.

Worked well eventually. Note to self: read instructions CAREFULLY, but it worked after I read them properly!

Yes it worked great. I did remove the sim and sd cards beforehand so as not to accidentally erase my saved data . Reinstalled them after startup and my phone is now back to functioning as I want it. Thanks for the hand.

What if my lumia 520 gets stuck on turning gears (reset mode)?

I have a password in my phone but the error is “try again in 164325 minutes“ so the only way is the hard reset, but my volume up were broken. What am i suppose to do? Is there any other way to fix this? Or I’ll just wait for that 123456 minutes to be over!?

It doesn't seem to be working for me but the phone is nearly dead and is on charge. Could that possibly be why?
