This post is an answer for Mr. Nizam question about the Nokia 5630 keypad problem. The problem usually occur on keypad IC. Here, mobile repair will share about how to make a direct jumper to solve the problem. This picture help taken from Mr. Monu's post, thanks to him.
If you have a blower, you can try to re-hot the keypad driver because may be there are solder lack. If the re-hot trick not working, try to make a direct jumper like showed by the picture above, but it is very hard trick to do. We don't recommend it if you are not an expert in the hardware area.
