Why does the OTA firmware upgrade fail?

<ul> <li>The user is in <em>&quot;Setting&quot;</em>—<em>&quot;Camera Setting&quot;</em>—Enter the <em>&quot;Device Information&quot;</em> page to view. During use, the user may appear such as: <em>&quot;Firmware Upgrade&quot;</em> button cannot be clicked, or prompts <strong>&quot;Firmware upgrade failed!&quot;</strong>.</li> <li>If the <em>&quot;Firmware Upgrade&quot;</em> button appears and cannot be clicked, it is usually because the APP has not obtained the upgrade file of the device from the OTA server, or the lastest firmware version of the obtained upgrade file is consistent with the current firmware version of the device, so the OTA upgrade behavior cannot be operated .</li> <li><strong>&quot;Firmware upgrade failed!&quot;</strong> appears, it may be caused by abnormal network fluctuations in the device, which caused the downloading of firmware upgrade files to be interrupted or failed; it may also be caused by abnormal conditions such as downtime of the device after writing new firmware. Users can view the page where the APP fails to determine where the failure may occur, or view the current status of the device to confirm; and try to restart the device and perform the firmware upgrade operation again. </li> <li>If you cannot confirm the specific reason, and the firmware upgrade operation cannot be performed after restarting the device, you can report the problem to the device manufacturer or hardware after-sales service personnel to assist in confirmation.</li> </ul> <p><img src="https://www.showdoc.com.cn/server/api/attachment/visitfile/sign/193936b4cca71c5828f48943ab11e64d" alt="" /></p>
