I have BB 8100 which I unlocked yesterday(using a free MEP2 Code), and did lots of OS changes after that, v4.2 to v.4.5, back and forth.
when i went to sleep i remember the cell working fine, but when i woke up keypad wasn't working. So i started looking for solutions by the Flashing firmware, so i did complete overhaul, by MFI multiloader an installed os 4.5 via desktop manager. Still no good.
earlier, even the trackball wasn't working, but now it is. but the keypad is still dead.
please any remedy to this?
(BTW, its rainy season here, so maybe moisture spoiled everything)
