Guys....take a look at these pictures and read careful this:
1. Phone starts ONLY when charger is connected -- then resolder or check V1001, V1004 and V901 transistors
2. Keys 7,8,9 don't work -- then make jumper as you can see in the picture bellow
3. reflow the processor
4. Check (resolder) keypad connector
5. Check each keypad line (using a multimeter)
