Nokia 5800 keeps restarting

[DayanandPatil]

I recently got Nokia 5800 mobile phone, it is not working fine after installing some new application. When i open any application it hangs for a minute and my Nokia 5800 restart itself. I have tried to solve that problem by deleting all the newly installed application but it keeps restating...

It's never a good idea to restore a backup after a FW upgrade or de-branding.A simple format of internal memory should sort any problems this has caused.Type *#7370#. Or try to take out the battery for a few minutes and also try to restart Nokia 5800 two to three time. If the handset is still crashing & rebooting after this, you either have a hardware fault or something in your MicroSD memory card is corrupt (try removing the card).

Which firmware do you have? Try updating your phone to the latest firmware and see if anything changes. Just remove your memory card and format it from computer and try opening phone without it .... if so , format your phone memory by writing *#7370#.

Use Nokia Software Updater, it is a Windows application by Nokia Phone Company that enables customers to update their mobile's device firmware to enjoy new functionalities. You can check the software and updates. To make sure your phone is really updated type *#0000# when in idle screen and check the software version.
