It seems like it's possible to mount the SD card of rooted android phone on a PC while the phone is connected to the PC via USB. This would be great for me because I want to keep essential files saved on my phone, edit them from the PC when I need to and bring them with me wherever I go. Unfortunately, the phones I want the most (nexus 4, HTC one, HTC one x with 64gb) don't have SD cards. Is it possible (on a rooted phone with cyanogenmod) to partition the "HD" on a phone without an SD card and then use that partition as described above? (The format of the partition is not very important to me.)
Will the solution suggested here make it possible to mount the .img file on the PC while the phone is connected via USB?
