How to: Reset the Nokia Lumia 800 and 900

Share This...

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!

    You totally got wrong on how to do the soft reset.
    In order to do it properly, you just have to press and hold 10 seconds the power button until the phone powers off.

    • Nirave

      I’ve updated the article, however sometimes just holding the power button will not do the trick. I’ve experienced issues where the power button will not work to reset the device.

  • Vishnu

    @Nirave- ur right just holding the power button didnt worked for me… your trick worked… Thanks alot!!

  • jios

    And what to do when the phone has no charge and only shows the battery warning signal…. 2 nor 3 finger reset work… warming it makes no diff. It just died on me….

    • Nirave

      Leave it on charge for around 12-18 hours, using the official charger included in the box. Try leaving it plugged directly into the main, not via a computer.

      It worked for mine, let me know how it goes for you.

  • jios

    OK, my problem is solved – by itself it seemed.
    I HAD it on the charger for a full 24 hours. Had already dusted off my old Philips Xenia…
    Then I connected it to my car charger (different brand). That charger is rather powerful; it can charge my phone from 3-4% to 99% in just over 2 hours.

    In this case I had the phone on the charger for approx. 15 minutes when it suddenly came to life again, and after rebooting itself 4 or 5 times it started again. I checked the battery charge at that moment, it was 2% and the remaining usage time was -5 min…

    HI. I had very similar situation today. Had charged my new Nokia Lumia via PC at work and one moment it got so hot and it switched off and I couldn’t switched back again at all. When I back home I have tried so different ways (connect to PC , take out sim…etc)and even called already my phone provider. But eventually ( as I have read your comments )I connected to the official charger and my Nokia back to life again ! Thank you guys!!

    Well apparently NOKIA is really **bleep** people off. I will be joining that LARGE group of **bleep** off users! Not to say that I have 2 Lumias and BOTH are having this problem. Yesterday my wife’s Lumia completely shut off after an overnight charge – it was 2 hours after she unplugged from charger that the handset turned off. NOW the phone is showing a drained battery and when I hold the reset button for a at least 30 seconds it still DOES NOT turn on. Mine on the other hand just switches off whenever it feels like it. When I am on a call, it switches off, when I play a game it heats up and my hands catch fire. This IS TERRIBLE! Not to say that I have recommended this phone to all of acquaintances and I’ve done two market research projects for my MBA thesis on this damn campaign and handset!! I am HIGHLY HIGHLY HIGHLY disappointed with what is going on.

    How can you BACK UP your files when the phone doesnt TURN ON?!?!?! .. you do a hard reset then what? lose all numbers?.. rectify that instruction please!! Thanks

    Can someone PLEASE recommend what we should do/where we should turn to resolve this irritating situation?.. Do we go to the place where we bought it? – because I got it from Dial A Phone, and I don’t trust them. Do I turn to NOKIA to send it for repair? DO I throw it in the trash and smash it with a hammer? I think Nokia should understand HOW **bleep** PEOPLE ARE WITH THIS G A R B A G E ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! :smileymad:

      It does say in the instructions that if you do a hard reset you will lose ALL data.
      If your phone does not switch on then you have a limited amount of choices here.
      I would suggest that you send your devices to Nokia for repair and explaining the problems that you are having with your phone. I would suggest, that if possible, for the future, that you make regular back-ups of your phone information.

    when making a call from my lumia 800 i cant hear a dialing sound or anybody on the line when making a call or recieving a call?????? any help here

    • Nirave


      The first thing to try is a hard reset as there is a slim possibility that the issue is caused by a software bug. However, if that fails to resolve it, we’d recommend you contact either Nokia Care or your network depending on where you bought it from as it will need sending off for a warranty repair.

      Remember to back up all your data as invariably it will get deleted off your device during both the hard reset and warranty repair.

      Hope this helps. Let us know how you get on.

  • Katie Furber


    Ive got an upgrade at the end of march with Orange and i love the look of the Noikia Lumia 800 so i went with it :) Ive had no problems with the phone until today. Went out with a full battery, I text a friend to come meet me outside a pub. When i got into the pub i went to show her something on my phone and it was dead. I tried to turn it on and no luck. I though it might be dead so when i got home i put the phone on charge and normally it will vibrate when its connect and nothing has happened. Ive tried the USB-PC but nothing. I cant turn it on :(

    PLEASE help….i need my phone for work and im lost without it :’(


    • Nirave

      Hi Katie,

      Have you tried to hold the volume down and power buttons whilst putting the phone on charge? That starts a battery pull, which might fix the problem.

      Otherwise try the hard reset options as outlined in this post. These will wipe your phone of any data however.

      let us know if this helps.

  • asif warner

    pls can you delete previous post and put this as i made a few mistakes thxs…

    • 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.

  • merrrie

    hi it happened to me to i was listening to some music during charge my phone switched off and I couldn’t switch it back again I have tried so different ways to fix it (connect to PC , take out sim…etc) it finally got fixed after a hard reset (strange was that none of my files was deleted)

    • Jon

      twice this year I’ve had to send my Lumia back.Same problem both times.Frustrating isn’t the word.Trying to speak to customer service in India and then my network provider has resulted in me using some choice words.Oh and when I sent it to be repaired the second time they lost the phone for 4 weeks!!!!they couldn’t check the emie number as the phone is sealed so it just sat on a shelf waiting.I hope Nokia drowns in a sea of it’s own making as I will never buy a Nokia product again and after my contract finishes with 3 I will look elsewhere.I have been with 3 for 8yrs and the way I have been treated is a disgrace

      • Nirave

        Its sad to hear you’ve had a lot of problems. I’d suggest reaching out to @ThreeUKsupport on Twitter to see if they can help as they’ve been pretty good at resolving issues where customer services can’t.

    • Nirave

      Hi Karl,

      Have you contacted Nokia Care to see what they can do to help? Also, where did you buy your Lumia from?

    • Tba

      hey this happened to mine I took it to where I bought it and they sent it off for free I got it fixed after two weeks it was fine after <3

  • uttam

    My lumia has died.will not turn on or charge.tried pressing all button combinations but nothing has worked

    • Nirave


      Are you using the official charger that came with the device? If it won’t turn on and you’ve tried everything we’ve suggested, you’ll need to get it repaired.

      Your best bet would be to take it back to the place you purchased it from and ask them to repair it under the manufacturers warranty. Or you can contact Nokia directly to see if they can help.

  • jgnland

    problema solucionado muchas gracias!!!!!!

  • Mick

    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!

  • Frustrated by Nokia

    OMG!!! I just tried the hard reset after 3 days of my phone not powering up and me getting terribly frustrated now my phone is back up but everything is gone!!!! Its a crazy brand new phone all over!! What do i do now!!?! This is crazy!

  • 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?
