I rooted my phone about a month ago without any issue, and now I'm trying to get back on the update path to go 902. The problem is when I have my bionic hooked up via usb to my computer and I try to drag a file onto the sd card, it says the card is write-protected. I have never had this issue before, it seems to have randomly enabled write protection on the sd card. How can I remove this protection so that my sd card functions normally? I am also unable to delete files from the sd card for the same reason.
