The phones need to be reflash you can go to www.topsony.com to correct the issue this is not a free site.

Or take the phone to a mobile center and have them flash the phone for you.

How do you flash a nokia phone?


  • Connect your device via USB cable and make sure it's turned OFF. Run Phoenix software. Select "NO CONNECTION" as connection type.
  • Click File then select "Open Product"
  • A window will appear, select the device model and the corresponding product code of your phone. To find your product code - Press *#0000# on your dialer while your mobile device is on.
  • Select "Firmware Update" option in "Flashing" menu.
  • Press "..." button on the top-right corner of the window to select the language pack/product code You want to use on your flashing. Click on the product code / language pack that you have selected and press OK button.
  • It will now show the Product code you have selected. Tick the "Dead phone USB flashing".
  • Click on "Refurbish". Then you'll get a pop-up window, follow the instruction. If it did not work, best option is to Disconnect the USB cable from your device. Press and Hold the Power button of your phone for 8 seconds. Once it vibrates, release the Power button and immediately connect the USB back into your phone's port. Then you should see the flashing starts.
  • After some seconds of flashing, it will pause and prompts for the same instructions as above. Do the same trick as mentioned in Step #7.
  • When the update process finished, a window will appear "Firmware updating succeeded". Your phone will automatically restarts when flashing is done. After that, you can safely remove your data cable from your device. In some cases, when using a CFW, it wont says "Firmware updating succeeded" but will just say"Flashing Completed". When that happens, the device screen will show "Local mode" or "Test mode" or inNokia Logo. You can try to turn in off by holding the Power button for 8 seconds untill it reaches the multiple vibration. Then restart your device - most of the time it works after that. But if not, you have to repeat the flashing process again.

    When I switch on my w850i, the screen is totally blank & white in colour. Pl guide me how to rectify this - Rahul


    Hi,
    If your phone freezes, hangs up unexpectedly, vibrates continuously or in other similar ways doesn't perform as it should, this can often be solved by performing a software update. Software may perform incorrectly for many reasons without there being a fault in the phone. Some problems may be fixed by re-updating your current software, while others may require installing a new software version.

    To keep your phone performing at its best, it's a good idea to perform a software update regularly. You might not always notice what an update has done, but it can prevent future problems.

    To update or reinstall the software please go to nearest authorized service centre of your mobile make and they will update or reinstall the software as required.

    Note: Reinstalling the software will delete all the content in your phone like contacts, calendar entry etc.

    Thank You
