About the firmware:
In order to upgrade your firmware, you first need to download your new firmware from internet. A firmware file comes zipped in a .rar or .zip file. To extract the zip contents, you can use 7zip(An Opensource archive editor). The size of a firmware file might be ~100-150 mb.
In a firmware file, there are

• xxxxxxxx.rc1 file
• xxxxxxxx.rc2 file (For the boot screen images)
• xxxxxxxx.ffs file (It contains everything needed for your phone to work)
• BOOTFILES Folder (It contains the phone's booting procedures)
