How do I completely format my phone?( HTC 510 0PCV1 )

[nsilano]

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!

Ummm if you completely wipe your internal storage you will have a pile of wires, plastic and some trace rare earth's. Buy an sdcard and try Link2SD from the Play Store.

The file system hierarchy on your phone is set up with various partitions by design so no, don't bother putting any effort into making your phone's internal storage into a single partition. See below for more details on partitions (note that different carriers/manufacturers often make minor alterations):

But the fact that you've rooted your phone does enable you to make changes that otherwise might have been more cumbersome. As Bg260 already referred to, installing a microSD card will significantly increase your storage options.
