Once you have successfully used a link to download your firmware, you cannot simply install it from the phone. You will need a computer and specialized flashing tools. Here is the general workflow: Prerequisites: A Windows PC. A high-quality USB data cable. Once you have successfully used a link to
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | | Boot ROM didn’t accept the image (signature mismatch) | Re‑download the firmware from the official portal; ensure you didn’t corrupt the file (use sha256sum ). | | Device hangs at “Bootloader: …” | Power‑domain configuration conflict (wrong voltage tables for your board) | Use the OEM’s “Board‑Specific Config” package; it contains a sp7731e_cfg.h that you can compile into a custom binary. | | Peripheral not responding (e.g., I²C sensor) | Default peripheral map in 1H10 does not enable the pins you need | Modify the configuration header (if you have a custom build) or enable the peripheral via the fwconfig command at runtime, then store the updated config to flash ( fwconfig save ). | | OTA update fails | The OTA client’s server certificate is outdated | Update the root‑CA bundle inside the firmware (requires OEM‑signed update package). | | Flash write fails with “ERASE_ERROR” | Flash memory is locked or worn out | Run a full chip erase ( spflasher --erase ) and re‑flash; if it persists, the flash may need replacement. |
