Flash your symbian Device with Custom Firmware using JAF and Phoenix

Do all the flashing at your own risk, you may damage your phone if done wrongly!
 This Guide has been created using Nokia 5800, but can be followed to flash any firmware for any device. (doesn't mean you can flash E72 fw in X6..etc).
For flashing guide with phoenix see: Hacking guide for Symbian phones using Pheonix

•  First you have to download your firmware files using navifirm (download from here )then copy all files to:"C:\Program Files\Common Files\Nokia\DataPackage\Products\RM-***\" 

•  RM-*** must be renamed to your RM version

• Then you have to download the hacked or customized firmware files you want to flash into your device.
• Rename those downloaded files to the one your actual firmware files are of.. e.g. if your genuine file name is abc.fpsx and asdf.V03 and the hacked or customized firmware files have name aaa.fpsx and bbb.V22 then rename those files to abc.fpsx and asdf.V03
• Copy those renamed files to "C:\Program Files\Common Files\Nokia\DataPackage\Products\RM-***\" and overwrite.
• Download & launch JAF v.1.98.62.exe(download JAF from HERE)
• Set options like in picture below: that is uncheck all boxes on bb5 tab except "manual flash", "dead usb" and "normal mode".
• Then check "use ini" and wait for pop up box to show up.
