Current phone model is an Android HTC 510 0PCV1, has a 4GB internal Hard Drive, but when I do a factory reset, it only shows that have 1GB. The phone has been rooted, but I don't understand the file system. While browsing of those unfamiliar folders, I did find some old personal files. Likewise, I would like to completely wipe all parts of the 4GB hard drive, including the 1GB that gets erased during a reset, and the additional 3GB that has a bunch of system folders and files. I would also, if possible, have the phone software to be on one 4GB partition so when I do a reset, it resets the entire hard drive... Is this possible? And if so, how do I do this? Thx!
