It is important to know which firmware versions can be upgraded directly to the latest releases, and which require more steps.
To upgrade HID EVO units from an earlier firmware version (2.3.1.603 or 2.3.1.605 for Edge
EVO, and 2.3.1.542 or 2.3.1.673 for VertX EVO) to the recommended firmware version, specific
upgrade paths must be followed:
- HID Edge EVO: (EH400, EH400-K)
Supported upgrade path: 2.3.1.603 or 2.3.1.605 → 2.3.1.841 → any later version
- HID Vertx EVO: (V1000, V2000)
Supported upgrade path: 2.3.1.542 or 2.3.1.673 → 2.3.1.791 → any later version
CAUTION:Upgrading directly from the earlier firmware to the recommended firmware will cause irreparable damage to your unit. Moreover, you cannot downgrade the firmware after it has been upgraded to 2.3.1.841 on Edge EVO or to 2.3.1.791 on VertX EVO.
