| File Name | Action | Bootloader Status | Data Wipe | Use Case |
|-----------|--------|-------------------|-----------|-----------|
| flash_all.bat | Flashes all partitions | Unlocked | Yes | General update, switching ROM regions. |
| flash_all_except_storage.bat | Flashes everything except user data | Unlocked | No (keeps apps/files) | Dirty flash (upgrading without wipe). Risk of bugs. |
| flash_all_lock.bat | Flashes all + locks bootloader | Locked after flash | Yes | Returning to stock for warranty/sale. | flash all bat xiaomi link
