IRIS4 firmware maintenance has more than one path. For daily use, the admin portal can check for updates automatically, and S3/C3 versions can be checked manually when needed. If OTA fails because of a network, power, or cache problem, browser flashing remains the recovery fallback.
1. How to Choose a Maintenance Path
| Path | Best For | Note |
|---|---|---|
| Automatic OTA | Keeping the recommended version current during daily use. | Keep Wi-Fi available and do not disconnect power during the update. |
| Manual Check | Support guidance, installation acceptance, or checking versions after receiving the device. | Compare the current and online versions in the admin portal before deciding to update. |
| Browser Flashing | Interrupted OTA, abnormal version state, or support-directed recovery. | Use Chrome or Edge with a data-capable USB-C cable and follow the authorized process. |

3. Why S3 and C3 Must Be Checked Together
S3 handles the screen, admin portal, Wi-Fi, cloud, and OTA interface. C3 handles target-yield control and Bluetooth scale readings. Checking only the S3 version is not enough; target-yield, scale, and dosing issues also require confirmation of the current C3 version.
4. Browser Flashing Is Not a Normal Download Link
Browser flashing is used for recovery maintenance and normally requires an activation code, authorization record, and browser serial connection. It is not a public firmware-download page, and users should not freely flash older versions. Before flashing, ask support to confirm the device model, symptom, and recommended version.
