Great news.
Use stock recovery to format
Method 1.
1. Connect to pc and boot into stock recovery
2. Factory reset
3. Reboot into download mode.
4. flash twrp.tar into the ap slot
5. reboot to recovery from main menu (not just reboot)
be patient- It may take a while
6. Advanced, terminal. Type multidisabler (twice).
7.
Or flash samsung multidisabler zip
Or, for older phones flash dmverity zip
8. Reboot to recovery from main menu (not just reboot)
Backup boot, data, super and dtbo
9. Reboot to system
