If you ever made TWRP (complete) back up of your phone, you can certainly go back to that point. But it sounds like you haven't done it.
If you don't have TRWP backup, you need to use someone else's.
1. Download Jack Mickey's file from here. You only need boot.emmc.win and system.ext4.win

2. Place two files to your SD card
3. Boot your phone into TWRP mode. Factory reset, clear data.
4. Use restore function. Navigate to your SD card and highlight those two files.
5. It will take about 3-5 mins. Your phone will go back to complete stock status.
