| Symptom | Likely Cause | Fix | |---------|--------------|-----| | | 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). | This is a specialized solution for on older J530S units
