Root E: Can't mount /dev/block/mmcblk0p1

You are having a problem with your sdcard. First what you need to do is connect your phone to your pc, then mount your sdcard as USB storage and copy (not move) everything on it to your pc.

From here, there's a few different things you can try. The first would be (after you power off your phone) to take out and then reseat your sdcard. Next would be to gently clean the contacts with a toothbrush ONLY. Next would be to format your sdcard through the phone's menu system and then transfer back from your pc only the folders that do NOT have a "." preceeding the name. Finally would be to get a new sdcard and then follow the instructions in the previous sentence.

good luck
