Yawezekana umedelete bahati mbaya, have u ever backed up your phone using blackberry desktop software? Kama ndio jaribu kurestore using advance rstoration kama sivyo. Nakushauri install hiyo software kwenye pc yenye internet connection then chomeka phone yako ita detect mapungufu automatically then you are good to go following the procedures including to update ur OS to the latest available one, there it will be as gud as new. Ila HAKIKISHA THERE IS NO ELECTRICAL PROBLEMS maana ikitokea in the mid of the process cmu inakuwa yako hiyo itabaki km toy "don't say I didn't warn you"
