2. Common Issues & Symptoms
| Code | Problema | Observed Behavior |
|---|---|---|
| SW-01 | Boot logo freeze | Stays on boot screen; system does not load |
| SW-02 | Reboot loop | Crashes and restarts during use |
| SW-03 | Launcher/UI failure | Home screen missing or partially loaded |
| SW-04 | No audio output | No sound, static, or noise |
| SW-05 | Network malfunction | Wi-Fi/Bluetooth unavailable; GPS not working |
| SW-06 | Display problems | Black screen, flicker, wrong resolution |
3. Root Cause Highlights
- Incorrect firmware or failed flashing (partition mismatch, verification errors)
- Missing or incompatible launcher/configuration
- Drivers not loaded (audio policy, touch, Wi-Fi/BT, GPS)
- Improper factory settings (CAN, panel parameters, resolution)
- Risky operations (rooting, disabling core system apps, aggressive cleaners)
4. Remote Repair Workflow
- Confirm motherboard and version (submit System Info/MCU screenshots). Guide: System Info Screenshot
- Technician analyzes and prepares a matching repair package (images + scripts)
- Execute USB/tool-based steps, then verify boot and key functions
5. Repairable Scope & Methods
| Problem Type | Method |
|---|---|
| System crash / no desktop | Reflash boot.img / system.img (exact board match) |
| Launcher broken | Replace launcher and startup configs; fix permissions |
| Network issues | Reset/replace Wi-Fi/BT drivers and settings |
| No sound / noise | Restore audio_effects / audio_policy and codec configs |
| Black screen / wrong res | Reconfigure panel parameters & resolution; touch calibration |
6. Typical Motherboard Platforms (Examples)
| Vendor | Common Models | Notas |
|---|---|---|
| Topway | TS10 / TS18 | Widely used aftermarket platform; strict firmware matching |
| FYT | SC7862 / UIS7862 / UIS8581 | High compatibility; many variants |
| XY-AUTO | P13 / 8581 | Common aftermarket platform |
| HC / MTK | T3 / T5 | Early or modified systems; precise matching required |
7. Operational Notes & Warnings
- Maintain stable power; never cut power mid-flash
- Do not “universal flash” without confirming board/partition layout
- Avoid unverified firmware/APKs
- Units that cannot power on at all should undergo hardware checks first
