[Revised] How to use SP Flash tool to flash Mediatek firmware

2.1 Download (Write) Modes

• Download Only: Writes firmware to the device without erasing user data (not recommended when switching between major Android versions).
• Firmware Upgrade: A safe, comprehensive mode that erases all partitions (including user data) before writing new firmware. Ideal for version upgrades or fixing corruption.
• Format All + Download: Low-level format of all flash memory followed by a full write. Use with extreme caution – this erases the NVRAM partition (IMEI numbers, Wi-Fi/BT MAC addresses), potentially leading to network issues.
• Format All + Download (Safe): A modified option present in some builds that preserves critical NVRAM data while formatting other partitions.

Flashing a Stock ROM

1. Load Scatter File: Run flash_tool.exe. Click “Scatter-loading” and select the MTxxxx_Android_scatter.txt from your extracted firmware folder.
2. Configure Options: Under “Options” → “Download”:
   • Check DA DL All With Check Sum (recommended).
   • Select “Download Only” (unless you need Format All + Download – this will erase IMEI/nvdata).
3. Select Partitions: By default, all partitions are checked. Uncheck preloader if you want to avoid the risk of a hard-brick.
4. Connect Device: Power off the phone completely. Click the Download button (green arrow).
5. Insert USB: While holding Volume Down/Up (varies by device) or no key, connect the USB cable to the PC.
6. Wait for Completion: The red progress bar indicates handshake, then purple/yellow bars show writing. A green checkmark indicates success.
7. Disconnect & Reboot: Unplug the USB, then power on the device (first boot may take 5–10 minutes).

6) Step-by-Step Flash (Typical: Unbrick / Download Only)

1. Install drivers and SPFlashTool v5.212.12 (extract archive).
2. Launch as Administrator.
3. Click “Choose” next to Scatter-loading File and select the device scatter (MTK_Android_scatter.txt).
4. Tool shows partition table and associated images. Uncheck partitions you don’t want to overwrite (e.g., userdata, calibrations).
5. Select mode: “Download Only” for targeted flashing; “Firmware Upgrade” if replacing more partitions safely.
6. Click “Download” (green arrow).
7. Power off the device. For many MTK phones remove/reinsert battery if possible; otherwise ensure powered off.
8. Connect device via USB while holding required key combo (varies by model) or simply plug in—SPFlashTool waits for device bootrom connection.
9. Tool detects device and begins flashing; progress bar displays percentage.
10. On success a green tick dialog appears. Disconnect device, first boot may take several minutes.

Phase 4: Post-Flash

1. Disconnect the USB cable.
2. Power on the device. First boot may take 5–10 minutes (ART cache rebuild).
3. If the device bootloops, perform a factory reset from recovery mode.
