hey guys...my phone was working great till last night.. i have the leaked 2.2 on it...i dropped it last night and the sd card keeps saying "blank or incorrect format" but when i try to format it, it doesnt do any thing. i checked it with my card reader and its not blank. does anyone here know if sbf back to stock will fix it?? also if i go ahead and sbf back to stock, at what point to i need to root? Before i download the ota right? or will it matter?
