My nokia 7610 has lost his phone memory & now im not able to apply new theams also can u help me .

you can contact the service provider........

Hello Buntty,
*#7370# only resets C: drive. The data stored in this drive will be lost and a company default files will be written. (but it won't work if the files are corrupted)
*#7780# only resets the settings which you changed other than factory defaults. The data in the drive will be safe.
To hard reset your Nokia 7610 please follow these steps;
- switch off your mobile (nokia 7610) - Hold down the following three buttons: Green (the call answer button), * button, and '3' button. - While holding these buttons, hold the power button for a second to switch on the phone. - Release when the phone shows the nokia hands logo or shows other signs of life like the language selection screen. - Make sure you make a backup first before doing the hard reset. All your data in phone memory will be lost.
Hope this helps.
If this solution was helpful for you please rate, Thanks!

The possibility of retrieving the lost memory is very minute as you have totally reset the phone .Since the entire memory is lost the chances are very minute.
Please find help for support from Nokia

Here's the solution, I just had the same problem LOL!
1. take the memory card out
2.On the memory card there is a little switch (it will be the little tiny piece on the side of the card thats a different color) slide it up.

That's it!

Use Nokia Software Updater (can be downloaded from Nokia.com).

you must save your data on the memory card
