OK, so sirvival's mmcblk0p1 was split in two. I could not dare to guess how it happened but it is fixable easily, even with just the tools available on the device. You need to delete mmcblk0p1 and mmcblk0p4 and recreate mmcblk0p1. If you run fdisk without parameters, it starts in an interactive mode, allowing you to give commands. But this is potentially a very dangerous area and I would really not dare to advice you further without referring to my own device. Please bear with me while I get it ready.
