Firmware is not displayed<\/h3>\n\n\n\n

Stromer distributes firmware updates for the electronic components (OMNI-C, controller, batteries and power supplies, ABS) via OTA (Over the Air). The different FW versions and a brief description are available on the myStromer AG service page<\/a> listed.<\/p>\n\n\n\n

Die Updates werden in Wellen verteilt. Bis ein neues, auf der Webseite gelistetes, Update auf dem eigenen Stromer ankommt kann es bis zu zwei Monate dauern.<\/p>\n\n\n\n

With firmware version SUI 4.5.1.1 (12.12.2025), you can actively search for an update in the Omni under MENU \u2192 SYSTEM \u2192 FW UPDATE and, if available, download and install it. See<\/a> OMNI \/ DISPLAY V1, V1.1 - 'Firmware updates'<\/em>

Alternatively, the customer has the option to manually request a firmware update through their dealer. The dealer then pushes the update via the Stromer Service Portal.<\/p>\n\n\n\n

Firmware download very slow<\/h3>\n\n\n\n

Bei \u00e4lteren Stromern mit Omni C und 2G\/3G Konnektivit\u00e4t kann es dauern bis ein Download einer neuen Firmware abgeschlossen ist. Dies liegt u.a. an der Gr\u00f6sse eines Updates aber auch am Umstand, dass in einzelnen L\u00e4ndern das 3G network switched off<\/a> and only the much slower 2G connection is available.<\/p>\n\n\n\n

2G (GSM)<\/td>9.6 kbit\/s<\/td><\/tr>
3G (UMTS)<\/td>384 kbit\/s<\/td><\/tr>
4G (LTE Advanced (LTE-A from CAT 6)<\/td>300 kbit\/s<\/td><\/tr>
5G (based on LTE, network slicing)<\/td>10 GBit\/s<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

With a good 3G or 4G connection, downloading even a large update takes a few minutes at most. With 2G it can take 15-30 minutes. An interruption of the connection is not a problem, OTA continues the download where it left off.<\/p>\n\n\n\n

The download progress can be tracked in the Omni via MENU > SYSTEM > ABOUT... or by tapping on the download icon. See also 'Firmware updates'<\/a>.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

If Autolock (Omni App > Configuration > Anti-theft protection) is deactivated, the Stromer goes into standby after 5 minutes. The firmware download is paused during this time. This can be prevented by pressing and holding a brake lever, for example.<\/p>\n\n\n\n

Firmware hangs<\/h3>\n\n\n\n

Backend problem<\/strong>It can happen that the download causes problems. This occurred, for example, during the outage in the Stromer infrastructure backend in April 2025. The automatic distribution mechanism failed, and updates remained stuck in the queue for weeks. A faulty download cannot be ruled out either. The consequence is installation errors and, if applicable, malfunctions in the components: Omni, Battery, Charger, Controller, or the blubrake ABS. The solution is to manually install the FW \u2013 see the info box above.<\/p>\n\n\n\n

Bugfix<\/strong>With SUI FW 4.3.4.1 from 06\/11\/2021, the bootloader of the OMNI Interface B & C was updated to version 2019.01 (previously 2016.11). This fixed an error that caused the OMNI to no longer start after an update.<\/p>\n\n\n\n
