Is it not directly to MAD2, look into service manual...there are some ressistors, check them.

@ARC

Does the phone haven't been downgraded to a much lower version? I encountered this once before when I'm experimenting with different MCU versions on a 3310 I'm working with.

BR,

All the keys are connected on the matrix. Just follow the key one path ways it can be simple connection problem. If not do not forget that UI chip is responsible for the lights, vibration and keypad. Try to replace it with hot air.

Hi,

I encountered this problem once when I downgraded one 4.45 version to 3.24 and when I upgrade it back to 4.45, it works again. I had also tried other versions such as 4.35 and the problem remains.I think that you must try to upgrade it back to the original version.

I also noticed that this problem I got it only in a batch of phone manufactured around july 01, you can check it by *#92702689# .Upgrade the phone to its original version it will work 100%.
