Hi
When a phone is manufactured the network it is being made for can stipulate what software they want on, what the buttons do etc etc. This is BRANDED firmware, they will also lock the phone on to their network.
If the manufacturer is just making a "Phone" Then it will put generic firmware on. This is not locked onto any network. However dependant on what sim you install and what network it is will determine if the buttons on your phone will do the job they where designed for.
For instance I have an unlocked K610i the home page button is located on the front fascia and the phone has a "3" sim card in. Because it has generic firmware installed and not "3" firmware installed this button is now defunked, wont work, nil, nada, stuffed!! Which is a good thing as when you pressed it by accident it used to hook up to the 3 internet and charge you for it!!
So you can install generic firmware and unlock but dont expect EVERY button to work.
With regards to flash files
