Please tell us what was the problem with your phones and how did they get in that situation.
Also we need to know if you tried to do anything else to them.

heat main board 100% will solve your problem

hi brothers ... if your blackberry 8900 all keys not working ... 1. make sure your keypad flex is ok .. if key pad flax is ok change joystick flex with ball ... its 100000000000000%% solution ....

Everyone seems to say 100% complete solution when it's not i think this could be a main board fault and 1 of your solders on your keypad pin out are broke, buy new phone or take to a shop...

I dont remove these diode,rehot the diode and check all key pcb. It is water damage? if is check all pcb.I have short circuit in diode on right side.

all dear user i did any thing with 8900 which are sugested by different people but i have got one 8900 in which only a few keys are not working in series like 45780 back button so please dont waste your time to do this in that just try to get right solution
thanks to all
