Nokia Lumia 820 Hard Reset to Factory Settings

Released during the winter of 2012, the Nokia Lumia 820 comes with an amazing design that got many users’ attention real quick. However, this smartphone is not all just about looks, as it also has an amazing hardware. Depending on whether or not you’re a fan of Windows 8, you will also like the way its operating system works or might be disappointed by it. All in all, most clients’ reviews show that this WP8 tends to work very well.

If you happen to have purchased the phone recently after it has been launched, you probably own it for close to 2 years now. After using a smartphone for an extended period of time, due to the amount of files we download, the many apps we install and the many different purposes that we use the device for, it can sometimes be affected by viruses or simply overloaded with data. In all such cases, the phone will probably start being slow and not respond to all of your commands. We recommend doing a hard reset on the Nokia Lumia 820 if this happened to you, and our article here will show you just how to do that.

First things first, you should know that this device comes with a 2G network, but also a 3G and a 4G one. It only works with micro-SIMs, so you will need to get one of these before thinking of buying this device. Its upper surface is black, but the bottom comes in various colors – my favorite one is red, but you can also get yellow, gray, violet, blue, white or fully black. In terms of storage capacities, the phone has 1 GB of RAM and comes with a slot for microSD where you can store maximum 64 GB.


The 8 MP camera placed on the back has Carl Zeiss optics, autofocus and geo-tagging while the VGA one in the front also works extremely well. To make your videos and photos look even better, you can use the video/photo editor that the device comes with. You can also use its Wi-Fi hotspot to download many other apps that will help you with this. The dual-core 1.5 GHz processor and its Qualcomm MSM8960 Snapdragon chipset are other two characteristics that make this Nokia Lumia very attractive.

How to restore the Nokia Lumia

Generally speaking, there are two ways of getting rid of your problems, and the one that’s best for you depends on what kind of issues you’re experimenting. For example, if you’ve been dealing with a device that takes forever to load its OS or doesn’t load certain apps, it might have something to do with your memory. Try erasing files that you don’t use or transfer them onto another device.

Similarly, this Nokia Lumia can sometimes crash or be slower because of an OS issue. This one can be solved using a simple soft reset. Different than the hard reset, this procedure will not delete all the files saved on the internal memory, but will only lead to a temporary improvement of the situation. It can be done by pressing and holding the Power key while the device is on until it completely switched off. It is then recommended to remove the battery and wait for 5 minutes before putting it back in.

If you have more serious problems like a virus that’s slowly destroying your Lumia 820, you may need to do something else. If you’ve already tried the soft reset version and the phone came back to doing the same once again, you will need to follow these steps:

  1. lumia820hardOn the Start Screen, tap the sign for the Main Menu.
  2. Go to Settings and look for the About Phone option.
  3. Choose Reset your phone and then press Yes to confirm.

You will be warned about your files being deleted, so please make sure that you create a backup in advance. Once this is done, you can easily proceed to rebooting the device, which should not take more than 5 or 6 minutes. In case you cannot access the menu, use this method:

  1. Switch the phone off and press Power (no.6).
  2. Holding the Power Key, press Volume Down (no. 5) for a few seconds.
  3. When the exclamation sign pops up, release both buttons.
  4. Use Volume keys to select Wipe Data and Power to confirm it.
  5. Select Yes to erase the files and press Power one last time.
