I had to download the firmware from Sam mobile and to the install myself. It is very risky to do it if you don't fallow the directions. Once I did the update I have not had any issues on getting anymore security updates for my phone.
It was too long ago for me to remember witch one I used. The only thing you can do is check the software version on the support site for the phone. And download that way. You might have to use one of the older ones. The time I did it, once i set the phone back up i had an update that came through OTA. I did use the option for a clean install, so make sure you back up all contacts and any thing else you need to
I also should tell you that this is very risky to do, you must make sure you download the right version for your model of phone or your phone will become a paper weight. Once you download the firmware make sure you follow the instructions step by step.
