You can't reinstall symbian, BUT, you can make hard or soft reset of phone (result is almost the same as reinstalling), but, unfortunately, hard reset doesn't removes your firmware (for example if u have upgraded your phone to new firmware, and want to get previous version back, this wouldn't help you...)
So, hard or soft reset just removes everything from your phone, and it will be as just-bought. And hard reset may also help in cases, if u cant start (boot) your phone, or get error ''phone start up failed. contact...'' or other serious errors. And it will also help, if u have totally messed everything up in your system files, or have some virus etc etc etc... so, it might be useful. There are several ways of resetting. So, let's start.
The soft-reset 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. And phone also might not even ask if you really want to reformat it, it might just start formatting immediately. So, don't play with that code, if you don't need to reset device. This reformats completely the C: drive. All applications and files stored on this drive will be lost and clean default files will be rewritten. But the phone might ask you a confirmation and you will have to enter a security code (12345 by default).
The normal-reset code for Series 60 phones is *#7780# You enter this code as you would enter a phone number in the Phone application. Normal reset restores .ini files from ROM but preserves user data (photos, 3rd party apps etc). But the phone might ask you a confirmation and you will have to enter a security code (12345 by default).
The deep-reset- 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. As data will be lost, you are advised to perform a backup first
Files and applications stored on E: drive are not be affected by these sequences, also SIM card isn't affected! But, just to be sure, better take out memory card and also SIM card. (You can insert some other, not-needed SIM card, if phone asks, to insert one)
But remember to make a backup of your phone before performing any of these formatting methods! You can use Nokia PC suite or some other programs to do that.
Firstly, most people post in the manenr displayed here not because they are Android fanboys but because they possess genuine concern for symbian. Frankly I've used only symbians till now from the N95 to SE Satio.Secondly HTC's not only sell phones with unlocked bootloaders but also release their driver sources due to which they are the android modding favorites.Samsungs also have unlocked bootloaders.Motorola unlocks the bootloaders for a select number of their phones like the original droid and the tablet Xoom. Plus they would also open up the atrix to the devs for a small fee.Plus google allows and encourages people to modify and flash custom ROMs. For this they created Fastboot and allowed people to flash by using custom recoveries. And NO, google has adopted the policy of opening up every inch of their OS to public scrutiny. Just think how else would Galaxy S get gingerbread as a custom ROM before it was released by samsung if v2.3 was not available to XDA modders.Now what most people are stating here is that the source is not truly open and is not given to the end users. Say you have an N8, even if you have the symbian source code you can't do anything unless Nokia provides you with the firmwares , a method to edit them and a tool to flash them. If you go on some of the symbian modding sites you would see that the custom ROMs are blazing fast as compared to the official firmware. Now symbian is in my eyes the most efficient, lightweight mobile OS. My suggestion to Nokia would be to allow us to modify our phone at the cost of voided warranties.
press the keys at once Red (End) + Green (call) + Photocamera Button and hold and switch on the mobile. For Nokia N97 Press both Shift keys + space bar and BackShift, hold, turn on the phone. (Note) All data will be lost during this process
