FAQ
I get an error message when I press start, and the handset refuses to update. What does it
mean?
1. The handset cannot use the firmware you have selected for firmware update. Please see
the next FAQ section for more details.
I get an orange error message and the handset refuses to update. What does it mean?
1. Your update is not compatible with the current, running firmware in the handset. There can
be several reasons:
•
Incompatible:
The firmware in the handset is not backwards compatible with the firmware
version you have selected for firmware update. Check the handset version and select a
firmware version which is upgrade compatible with the current version.
•
Not allowed:
The firmware version you have selected is not allowed to be used.
•
HW Not Supported:
The hardware version of the handset does not support the version of
firmware you have selected for firmware update. Please select a compatible firmware
version.
•
No FWU DLL:
Some handsets require a dll to do firmware update. The fwu service dll file is
missing for the type of handset you are trying to update. You should have a dll called
FwuService<<handsettype>>.dll inside your install directory. Re install unified support tool
to restore the needed dll file(s).
1. Please consult the release notes for a description of compatible firmware versions and a list
of not allowed software versions.
How can I force an upgrade if the handset and the firmware image have the same version?
1. Connect the handset with firmware version vX_bY.
2. Select firmware image with version vX_bY.
3. Ignore the "Completed" shown in the tool and press the "Start" button.
What should I do if the driver is reinstalled every time a new handset is connected?
1. If handset/hub is connected to a computer with Windows 7, Windows 8 or Windows 8.1,
then check if the port on the computer is USB 2.0. USB 3.0 ports combined with Windows 7
will cause the driver to be reinstalled. Therefore it is recommended to use USB 2.0 ports. If
the computer has Windows 8, then USB 3.0 can be used without causing the driver to
reinstall.
What should I do if the connected handset does not show up?
1. Check that the selected model, in the File menu, matches the connected handset.
