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 ).
