Your computer needs to communicate directly with the tablet's motherboard while it is in download mode. Download and install the official on your Windows PC. 4. Enable Developer Options

The stock Samsung recovery only allows you to perform basic factory resets or install official, digitally signed updates. By replacing it with TWRP, you gain advanced system administrative powers:

| Feature | TWRP 3.0.2-1 | TWRP 3.7+ (modern) | |---------|--------------|---------------------| | Android support | Up to Android 8.1 | Android 12–14 | | FBE decryption | No | Yes | | Fastboot mode | No | Sometimes | | Theme engine | Limited | Full XML theming | | Backup compression | gzip | zstd (faster/better) | | A/B partition support | No | Yes |

A: No. Flashing this on the SM-T561 will hard-brick your device. The partition layouts are different. Look for twrp-sm-t561.tar instead.

Enable Developer Options on your tablet by going to Settings > About Tablet and tapping the "Build Number" seven times. Then, go back to Settings > Developer Options and turn on both and OEM Unlock .
