If you miss this and boot to system, the stock recovery will overwrite TWRP. If that happens, repeat Steps 1–5.
| Problem | Fix |
|---------|-----|
| Stock recovery returns after reboot | Auto-reboot was on; reflash with it off & manually boot to TWRP first |
| Can’t mount /data | Format Data (not just wipe) in TWRP → Wipe → Format Data → type yes |
| Odin fails (auth) | Bootloader locked or wrong file for your exact model |
| TWRP touch not working | Try newer TWRP version for on7xelte (3.7.0+) or use USB OTG mouse | twrp-3.6.0-9-on7xelte.tar
