Well, my Nokia 3230 is no more. Here is its post-mortem report!!
I wasted a lot of time taking that set apart and understanding the embedded system. I am not a hardcore embedded developer, nor someone with an electronics background — just a statistics graduate. So quite a lot of effort went into these following pictures.
Front side of the keyboard where the display joins the cell.
Back side of the main board, where the keyboard and main board connect (“you can see three slots as connectors; only two (the orange ones) are visible in the image!!”). That connection is the very reason my handset is dead!! It is the most delicate part of the Nokia 3230, and possibly in other sets too.
A few things I want to know more about: where is the main board coded, and how is its OS — Symbian — installed??
