Can't find any disks

[newacct]

I have an iPhone 4 CDMA that failed halfway through an update and was in recovery mode. I successfully put in in DFU mode and started up ssh-rd and was able to SSH into it. However, I cannot find any disks. The phone is on iOS 7 if that makes any difference.

-sh-4.0# ls /dev/disk0s1
ls: cannot access /dev/disk0s1: No such file or directory
-sh-4.0# ls /dev/disk0s1s1
ls: cannot access /dev/disk0s1s1: No such file or directory
-sh-4.0# ls /dev/disk0s2s1
ls: cannot access /dev/disk0s2s1: No such file or directory

In fact, there are no "disk*" files in /dev at all:

-sh-4.0# ls /dev
