the half rate code dosent really work i have tried it is it specially for some nokia models or for all nokia models i have tried it on 7600 but not working

[Varun]

ya dont know for sure which model supports half -rate...codec

but in half-rate voice quality is lowered to save battery

[Eminem]

did u try it any time. i guess the mobile operators charge special fee for the sound quality so when we reduce it the talktime increases correct me if i'm wrong :grin:

[Varun]

the operator charges you based on duration of call and not on quality...

ya tried it ..when i was in college ..wanted to make a important call but no battery

used this and managed to talk

some of these are only meant for s40 phones. so most codes will not work on a s60 phone.

The soft-format code for Series 60 phones is *#7370# . You enter this code as you would enter a phone number in the Phone application. It performs a format of the Internal drive - All data will be lost if you use this feature.



The method of performing a hard-format, i.e resetting it completely to factory defaults and removing all data, is as follows:

1. Switch off the phone.
2. Hold down the following three buttons: Green (call answer) button, * button, and '3' button
3. While holding these buttons, press the power button and switch on the phone
4. When the message 'Formatting' appears on the screen, release all of the buttons

Note that you shouldn't switch the phone off or remove the battery when performing either of these operations, and it's advised that the handset has a reasonable amount of battery charge before performing a format/reset.
