[AC Question]

I rooted my N910F and it worked perfectly for 7-8 months. Recently it started rebooting itself unexpectedly and going into download mode OR showing message MMC READ FAILED. . So every time i had to pull out the battery and then boot it. After 5-6 days with this problem. Now my phone NOT GETTING ON, NOT CHARGING and simply DEAD (i suppose). Is there any way i can switch it on again once and COPY few files? THANKS IN ADVANCE for anyone's help
