Steps on how to Flash Any Nokia GSM phone Firmware using JAF and Navifirm

I have spent the past three days learning how to flash my new Nokia 5230 with the latest firmware. The reason was that I want to change the default language, and Nokia is limiting the number of available languages in each “firmware package”. Flashing Nokia phone is not something easy to do if you are learning from scratch. However, I’ll share my experience and the steps and hopefully you will get better ideas on what to do. Just FYI, you can also use the same set of tools to unlock your Nokia phone.
