Document ID: RK322X-FW-0712
Target OS: Android 7.1.2 (Nougat)
Build Fingerprint: NHG47K
SoC: Rockchip RK3228A / RK3229

Flashing steps (general, for RKBatchTool/RKAndroidTool)
- Install Rockchip USB drivers on the PC.
- Extract the firmware archive to a known folder.
- Run RKBatchTool.exe (or RKAndroidTool).
- Click “Restore” or “Upgrade” depending on the tool and select the firmware image (.img) or the scatter file.
- Power off the box.
- Connect the box to the PC via USB while holding the recovery/upgrade key (varies by board — sometimes a small button or use a pin in the AV hole). If no button, connect while powering on; the tool should detect “Found Loader” or “Device Connected”.
- Start the flashing process in the tool and wait. Do not disconnect until it finishes and shows success.
- First boot may take several minutes.
