| Criteria | Updater (automatically) | Hand-held firmware (fastboot/recovery) |
|---|---|---|
| Security | ✅ Minimum risk of "brick", compatibility check. | ⚠️ The error can lead to a broken device. |
| Data retention | ✅ Normally does not erase user files. | ❌ Often requires wipe data (full reset). |
| Flexibility | ❌ Official firmware only. | ✅ You can install custom recovery (TWRP) and informal firmware. |
| Speed. | ✅ Quick updates (incremental patches). | ⚠️ Longer (complete reflashing of all sections). |
| Skills required | ✅ Suitable for beginners. | ⚠️ You need knowledge. ADB, fastboot, unlock the loader. |
When to use Updater:
