How to: Reset the Nokia Lumia 800 and 900

by Nirave22 November 2011

So you saw all the hubbub during launch day and decided to buy Nokia’s new Windows Phone device, the Lumia 800 or the flagship Lumia 900. Every so often, every phone needs a good battery pull now and then. Or something more sinister comes up and you need to factory reset the device.

Can’t work out how to do either when the phone won’t load up? Not to worry, I’ve got you covered. Here’s how to reset the Lumia 800 and the flagship Lumia 900:

Soft Reset

Soft Resets are sometimes also known as battery pulls, where pulling the battery out of a phone and replacing it can fix some minor issues with your phone.

Unfortunately with Nokia’s latest devices, the polycarbonate unibody shell means you can’t pull the battery out.

Here’s what to do instead:

As per the image, hold the Volume Down and Power buttons down until the phone vibrates three times. The phone should successfully restart with the Nokia logo after a few seconds.

Hard Reset

Sometimes a battery pull just won’t fix the problem. In these cases, it’s time to do a hard reset on the phone. Warning: All data will be lost from the phone when performing a hard reset.

If the phone powers on, navigate to Settings > About > Reset your Phone.

This will reset your phone to factory settings. If the OS won’t load up, use the method below.

Step 1: Backup all your data

The first step is to backup all your data. I personally use cloud storage with Google but you can also use SkyDrive and other solutions to backup your data.

Step 2: Switch the phone off.

Once again, make sure your phone is off whilst using this method.

Step 3: 3 button reset

Almost all Nokia phones have an infamous 3 finger reset and the Nokia Lumia 800 is no different. Similar to the soft reset above, the hard reset is performed by pressing the Volume Down, Camera and Power buttons. Hold all three buttons down until the phone vibrates then release power button and hold volume down and camera for a further five seconds.

Step 4: Phone is reset!

Success!! Your phone is now reset to factory defaults.

In case you missed that, here’s a quick infographic to explain it.

We hope this guide has helped!

    A word of warning to all.

    Do NOT do a hard reset on your phone until you’ve tried to back up your data first!!!!

    I tried all the tricks to try and get my phone out of the loop for days then finally I resorted to the Hard Reset and now I’m looking at a completely wiped phone with no way to restore my messages, contacts, call history, apps, pictures, music and ringtones.

    There are a few unofficial apps around to back up your phone, I highly recommend looking at these first and please ONLY use the Hard Reset as a LAST RESORT as it is very likely that you will lose everything!

  • Paul Vansteenkiste

    I had the same but are you sure you are doing it right
    Hold down the 3 buttons until it vibrates and then let go of the power button and hold the remaining buttons for 5 more seconds. I did it that way and it worked. Ik had the same issue you had.

    I have replaced the battery on my lumia 800, now all it dose is buzz as if it is turning on but a second later I buzzes again, nothing on screen at all and it keeps on doing it, no soft or hard reset has cured it, answers o a postcard please?

  • PotatoYumYums

    Hi, my touch screen doesn’t work at all, the display works fine so if I get a message it pops up as normal and the buttons work alright. I let the battery drain (i can’t turn it off without the touch screen) and plugged in the charger but that didn’t work, but it wouldn’t charge, there was a ? over the battery symbol. I don’t know whether I daren’t try a hard reset and I doubt it will work and a soft reset didn’t help, has anyone else had this problem?
