| Symptom | Likely Cause | Fix |
|---------|--------------|-----|
| Device stuck on “Downloading…” forever | Bad USB driver / cable, or phone not truly in download mode. | Re‑install drivers, try a different cable or USB port, hold Volume‑Down while plugging in again. |
| “Error 0x01 – Read failure” | Corrupted firmware file. | Re‑download the stock firmware (verify checksum). |
| Phone boots but still single‑SIM | Patch didn’t merge, or wrong firmware version. | Double‑check the patch matches the firmware build number. Re‑flash using the manual merge method. |
| Bootloop (stuck on logo) | Flash aborted mid‑process, or mismatched DA version. | Re‑flash using the correct DA (often found in the same firmware package) and make sure the download completes fully. |
| No network on SIM 2 | Radio still locked to SIM 1, or SIM 2 not activated by carrier. | Verify the second SIM works in another phone; if it does, repeat the flash or try a different dual‑SIM patch version. |
| Device won’t enter download mode | Fastboot/bootloader locked. | Use HiSuite → “System Update” → “Force Update” or ADB reboot download (adb reboot download). If that fails, you may need an unlock tool for the bootloader (outside scope of this guide). | Could you clarify exactly what you're trying to achieve
