K3520/E169 Firmware Update does not work

[drill_sarge]

Hello, I have a K3520 (Huawei E169) data stick (from vodafone). I would like to update the firmware, but this does not work. the updater detects the stick, but when I click ok and the flash process starts, I get this error message:

"The wireless terminal inserted is not Firmware, update wizard can't work on"



my firmware is:
Current firmware-version is: 11.314.12.02.00
the target version is: 11.314.17.00.00

I tried the firmware provided by Vodafone (my operator where I got the stick from) and newer one (from dc-files.com for example)

and my second problem: dc unlocker can't detect the modem.
(I'm gonna install the latest (beta?)version and upload some details soon, but my main problem atm is the firmware update)

Be sure that all connection software running are closed before start upgrade.
Bes ure also that the modem dongle is correctly installed, and check the com ports (Application and Diagnostic) of the key.
Verify that the key is correctly recognized by dc-unlocker with autodetect.

nothing is running in the background, nothing no vodafone or huawei software (I am using mwconn; which of course is not running during the process).
dc-unlocker doesn't detect my stick with autodetect and when I set the ports/model manual it doesn't detect it, too.

it doesn't detect it. I tried to set com ports and model (e169/k3520/unknown huawei), but nothing helps.

If you can not detect modem you should check the fallowing:
Check, if the drivers are installed
Check, if the connection software for this modem is closed and modem is not connected to internet
Check, if you use autodetect function in dc-unlocker software
Check, if you use latest dc-unlocker software version.
