[Tutorial] How to Reset/Remove Nokia Mobilephone’s security code using Nokia Care Suite?

Note – The method described below is actually “Dead phone USB flashing” so you can follow this process to flash (re-install phone software) dead/working Nokia mobiles for reasons other than a lost security code also.

It happens frequently that we change the default security code of our phone and then forget the new code. This results in a locked phone most of the time and one has to shell out money to mobile service center or local mobile repairing shop. However with a little know-how and following the steps given below you can save some money and most importantly have peace of mind by resetting the security code yourself. Before getting started with the process let’s go through the basics and the precautions –

Warning – This process applies to Nokia mobilephones only (Asha, S40, Symbian and Lumia). All phone data (and mass memory data if present) will be lost during the process so backup the phone if possible. Also charge up phone’s battery to full (or at least 3/4th) before going ahead with the process. Do this at your own risk I am not responsible if anything goes wrong.

A computer running Windows (XP/Vista/7/8), your locked Nokia mobile and its USB data cable
Internet connection (a fast connection is recommended to download firmware files)
Nokia Care Suite (NCS) software installed in computer (search Google and download). Better look for and install an older version of Nokia Care Suite (rather than going for the latest one) because Nokia has blocked open access to firmware files in new version of NCS (from May 2013 onwards). Thus you won’t be able to download mobile software files via new version of NCS. You may refer to this post to know more about Nokia Care Suite.

1. First up, note down your mobile’s product code (it can be found at the sticker below battery in the format 0xxxxxx – zero followed by 6 digits/alphabets) and type (can also be found at the sticker in the format RM-xxx). These codes will be required to download the correct firmware files according to your mobile model later on

2. (Computer must be connected to internet) Launch Nokia Care Suite in computer and at the main interface double-click “Product Support Tool for Store”. At the opened window sign in with “CareSuite External” option if prompted.

3. Go to File – Open Product. At the Open Product window select your phone from the list (enter your mobile’s RM-xxx code in the filter and it will show up) and click Open

4. (a) Now click Programming – Recovery (found at the bottom left of window).
At the recovery window un-check “Automatic product selection” and “Update automatically” boxes
Select “No connection” at the top left of window
Now enter the product code of your phone (as noted in step 1) and click “Update list” button. Wait for a while as it loads the latest available software for your phone. When the software details are shown click Start button. NCS will start downloading the phone software files. Wait for the download process to complete; it may take several minutes depending upon your internet connection speed and phone model. When downloading finishes NCS will try connecting with phone and will give an error pop up saying that connection with the phone has lost (because we have not still connected the phone with computer). Let the error box remain this way (don’t click any button right now) and go to step 6 below

(b) If above downloading method does not work then try this
At Product Support Tool for Store window go to Tools – Firmware Download. At the Firmware Download pop-up, enter your phones product code and click Check online button. The latest available software version details will be shown for the product code after a while. Leave the Optional content files box unchecked and click download. Software download will start – let it finish.

(c) If both of the above methods do not work then download phone’s firmware files via Navifirm+ Download Navifirm+ from here and run it. Enter phone’s product code in the space provided and press enter at keyboard – wait for a while as Navifirm will load the files in the extreme right pane – select all files (except the one named “Memory card content”) by clicking Mark All button or checking boxes manually – now check the path where to download the files and click Download button – Navifirm will start downloading files – wait for the process to complete – when done go to the location where these files are downloaded – select all and copy them – now go to C:/ProgramData/Nokia/Packages/Products and create a new folder in last “Products” folder and name it RM-xxx (where change xxx to as per your phone type for example it will be RM-596 for Nokia N8) – when created, open this folder and paste all copied files in it – close the window.

5. If Nokia Care Suite downloaded phone software files as described in 4 (a) then go to step 6 below
However if you have downloaded software by 4(b) or 4(c) option then switch back to Nokia Care Suite and again go to Programming – Recovery – enter phone’s product code and click Update list button (it will show phone’s software/variant details as per downloaded files) – click Start button – NCS will verify the firmware data package and finally will give an error pop up (because we have not connected the phone still) – let the retry popup box remain.

6. Remove phone’s battery – connect USB data cable with the computer (not phone) – now you have to do following steps in the given sequence and as quickly as possible –

(a) Connect data cable with the phone
(b) Insert the battery in phone and then
(c) Quickly click Retry button at the NCS error box

If everything goes right NCS will start flashing the phone. However if the process does not start (NCS gives error again), don’t worry, repeat 6(a) (b) and (c) quickly again and again until NCS starts flashing. Once started, wait for the process to complete – disconnect when done – enjoy your unlocked phone with default security code (12345)

All this “quick” exercise is due to the fact that we do not want NCS to detect the phone as working. This is because the security code cannot be reset by flashing the phone in working condition rather it can only be done by “Dead phone” flashing (recovery mode as described above).
