The title pretty much says it all. When running a factory reset, upon reboot I find that none of my files have actually been erased. My settings and apps are all gone, as they should be, but things like my pictures, alarms, and music, all still remain. I'm okay with actually deleting the files off the phone via a file browser, but I'm wondering why they aren't being erased as the system claims.
If it makes much of a difference, I reset my phone which was running the original stock OS and had been rooted. After finding my files still on there, I flash Peter Alfonso's Stock Rooted Rom -ICL53F (Toro - Downloads), and have factory reset under that rom twice, also with no luck at a full erase.
I'm going through Settings > Backup & Reset > Factory data reset > Reset Phone > Erase Everything. It reboots up to the android with the open chest/hologram animation, reboots again about a minute later, and when all is said and done, my files are still all there. Am I doing something wrong?
