Need full reset to factory and delete all personal data
So I'm giving away my old Blu Life One X 2016. It's rooted running stock and TWRP. I want to reset to factory settings and delete all personal info. I tried using the Factory Data Reset function but it didn't completely reset the phone nor did it delete photos.
When I bought it I replaced some function sounds of my own (like unlock sounds and keyboard typing) and installed my own boot image; and all these are still present even though I did a factory reset like I mentioned.
Any help how to delete all my personal data and restore all factory settings?
Thanks
