@GSMxpert, thanks. I took it to a phone engineer and he told me that there's no solution. When the phone is powered on it vibrates twice with a blank white screen . He says that sign means that it has a bad GDFS and that there's no flashing that will repair the GDFS. How possible is that, and does it make sense. I really need your response.  Am not much of a techie guy when it comes to phones.

who said its unrepairable,  i have done so many,  when i come to lagos i will help u out,
