Those steps are quiet long but does that all really works. I means wouldn't that cause any issue in the phone. This already looks like a small hack for the phones security certificate. But the same is worth trying. Does there is a kind for similar information available for other Nokia models also. I was looking for a similar information on an Nokia Smartphone. I found some tools that can fix, but they are had already warned that this can cause some major error in the phone.

Some phones in that needs a kind of firmware update. Or else things in that does not work. I had found that on older phones a proper firmware update is needed. That is because the applications wouldn't identify the phone hardware. So because of that you get those update issue and error on your screen. Try getting a newer firmware update first and then only you can try to work on other things to modify the phone software.
