Your phone is an n73? Format the phone.

To format

  1. turn phone off.
  2. hold the following keys WHILE its turning back on: (3 + * + green call key)
  3. do not let go until it asks you about your location
Your phone will gain 44mb back and go back to normal. Phone will respond a lot faster too, as if it were new. Viruses would be deleted as well as other junk stuffed inside.

Important reminder:

If you have anything stored on the phone memory that you woudn't want to delete, such as pictures, videos, or whatever, back it up to your memory card or computer. The format process deletes all stored memory on the phone, but not the memory card.

    Ah. It's not switching on at all. You're going to have to bring it to a technician to have the OS reinstalled. The current OS has been corrupted, so you'll need a new one. Here in the Philippines, it costs 300 pesos, which is pretty cheap. Check out your local area and find a tech to reinstall the OS.

    Sunli2300, to format your memory card, you'll need to hook it up to a computer (with the help of a card reader). Once the computer recognizes it, it'll show up as "removable drive" or whatever. Right click on it, then select "format". It'll delete everything on the memory card.

    Hope this helps

After downloadin i keep gettin an error sayin 'unable to install'. Am using a nokia n95. Please help me.


I have nokia n 73 and i too come across this problem quite a times. First of all try switching off the phone and then try reinstalling the application after restarting the phone.


There is nothing wrong with the phone for this issue but what happens is some times the application we download has its certificate expired and when we try to intall the application it says unable to install.

So try downloadng the latest version of the application and if possible from some different site or official site of the application provider.
I hope that will solve your problem as it solved mine number of times.
