| Symptom | Likely Cause | Solution |
|--------|--------------|----------|
| Device stays in blue screen after flashing | Incomplete firmware or power loss | Reflash with original firmware, then try unlock file again. |
| No 4G, only 2G | Wrong baseband firmware | Find a firmware with matching radio version (look at modem_fw_ver). |
| "USB device not recognized" | Driver conflict | Uninstall all Huawei modem drivers, reboot, clean install. |
| Flasher says "Bootloader locked" | Newer e5336bs2 variant with locked fastboot | Use PotatoNV tool (only on certain chip revisions). |
| Error | Cause | Solution |
| :--- | :--- | :--- |
| Firmware update failed | Wrong file type or corrupted download | Re-download from another source. Ensure file size matches known good copy (~20-30MB). |
| Device stays red light | Bricked (wrong board version) | Attempt recovery by pressing reset pinhole while inserting battery. If no response, device is dead. |
| SIM not recognized after unlock | Radio band mismatch (Unlock firmware might have disabled your local LTE band) | You must reflash the original "portable" stock firmware from your carrier, then use a paid unlocking code instead. |
| Wi-Fi works but no internet | APN settings deleted | Manually enter your new carrier's APN in the web interface (e.g., internet, wap.cingular). |
If you share exactly what you’re trying to achieve (e.g., “Use a different carrier” or “Change band settings”), I can give you precise, safe steps.
