Back in May, I bought a Docomo F-03D phone and it recently stopped working. I was using it one morning and the screen happened to freeze. I took out the battery and put it back in and when it was turned on, the screen freezes and it wouldn't respond at all. It basically says "No Service" when I do have a sim card inserted and the homescreen is blank.
I've tried to run recovery but it also says "sd downloading failed file open error". Please help me? I really want to keep this phone and make it work
