Today i am going to discuss about customization of symbian os.

Using custom ROM you could modify the look and feel of your existing mobile os.Add may application as they came inbuilt with your mobile.You could also upgrade your ROM version and get all the updates and patches provided by the mobile manufacturer company.

For this purpose you need to download the ROM image file for your specific mobile devices.I spent a lot of time by searching and searching .. but nothing found so easy to use.So i don’t want you to do the same, so just do a search for navifirm and download the software.It will give you access to the all device specific ROM version with easy to download option.

For this purpose you need to download the ROM image file for your specific mobile devices.I spent a lot of time by searching and searching .. but nothing found so easy to use.So i don’t want you to do the same, so-

1. Just download NAVIFIRM from here by clicking the screen shot and start downloading the firmware.It will give you access to the all device specific ROM version with easy to download option. Now check firmware details of your phone by *#0000#, run NAVIFIRM, search RM-xxx/RM-xx (RM is your device’s hardware compression type) in the products panel.check the version in next panel, select the variant, download the firmware files. (REMEMBER! DOWNGRADING OR UPGRADING WITH DIFFERENT FIRMWARE FILES WILL BRICK YOUR PHONE. SO YOU CAN ONLY UPGRADE WITH CORRECT FIRMWARE FILES). Save them to (system drive/program files/nokia/phoenix/products/RM-xxx/).

2. Now download JAF and P-KEY emulator from HERE(make a link to download jaf and p-key). now install JAF in any drive. Now to run JAF you have to run P-KEY emulator. If you are using XP/VISTA run the emulator normally but for WIN7 run it in XP-compatibility mode and administrator mode.

3. Now click GO-button to run JAF. It will show an error message “Box driver not installed”. Click OK. Go to BB5 tab. Select “Manual flash”, “Dead USB”, deselect “CRT 308″, select “use INI”. A pop up screen will appear. From this select your phone. JAF will load firmware file in its cache. Now switch off your phone and connect it to pc by USB. Hit Flash button then OK. But remember again LOWER VERSION OF FIRMWARE OR DIFFERENT VERSION i.e. [note_box]DIFFERENT RM-xxx WILL MAKE YOUR PHONE BRICKED.

Try it at your own RISK.
