Default [Q] How to format dev/block/mmcblk0p25

Hi. I want to sell my phone so I'm looking for deleting all images.
Things to know: My galaxy s3 mini is rooted and have Carbon 4.4.2 ROM and Team Win Recovery
I tried those things:
- Delete the file mmcblk0p25 via File Manager
- Wipe Internal Storage

After I deleted the file mmcblk0p25 via File Manager it dissapears, but looking for deleted images (using Disk Digger app) I keep seeing the file and my images after I deleted it.

Need some help, thanks!

Go to recovery mode and make a factory reset. It will remove all user data and cache.

Is that a file recovery app?
It's not any different than any storage media. Files can sometimes be found even after formatting because they are not being overwritten at all, just wiped.
To be sure you probably would have to rewrite the whole block a lot of times before every fragment is gone.
What kind of top secret images is there?

If you know Linux you can make a new ext4 data.img of correct size in simg-format and flash it to your phone It will be completely empty for sure.
