Learn what these updates mean for returning to earlier firmware versions.
This article applies to:
- 5 Series Firmware 97.3.0
- 6 Series Firmware 1.0.0
Important: After installing New 97.3.0 and 1.0.0 Firmware, you cannot return to an earlier firmware version using a standard .mender installer released before these updates. If you need to downgrade, contact B9C Support for a special downgrade installer and guidance.
For the complete list of changes in each release, refer to the firmware release notes. This article focuses on downgrade restrictions.
How to request a downgrade
Contact B9C Support if you need to return to an earlier firmware version. The downgrade requires a special Downgrade Gateway Firmware installer for your printer series:
| Printer series | Downgrade Gateway Firmware |
|---|---|
| 5 Series | 96.11.0-downgrade |
| 6 Series | 0.6.0-downgrade |
These special installers are available through B9C Support rather than as general downloads.
