please note that by debranding your device by the hard method you probably lose your warranty!

With the hard method the flashmemory of the modem will be changed persistently. This is also reversible, if you backup the original content of your flashmemory (also described in the following instructions). However if your device breaks down before or during restoring the original content of the flashmemory warranty claims may be refused.

Install the original dashboard from your device, because later operations will require all drivers to be installed.
Download QPST and install it.
Click "Start", "Programs", "QPST" and start "QPST" Configuration" and select the "Ports" tab
Now click "Add New Port"
Find and chose the port labeled "USB/QC Diagnostic" and click "OK".
note: If more than one "USB/QC Diagnostic" port appears, you have to find the correct one by trying each one. If you got the wrong one the "Phone selection" in step 7 won't show the "Unknown" phone but will be empty.
Chose "Start Clients" from the menu and click "EFS EXPLORER"
In the following dialog you should see an "Unknown" phone, which you select and then confirm with "OK".

Now QPST will read the EFS filesystem of your device:
When QPST has finished reading it will show up several files. Now you might first want to back up the existing content of the flashdrive, which is stored in the file "ZTEMODEM.ISO". Therefore right-click "ZTEMODEM.ISO" chose "Copy File from Phone"...

and chose a destination where the file should be saved and click "OK".

Now QPST will backup ZTEMODEM.ISO to the selected folder, which may take up to ~30 minutes.
note: keep this downloaded backup version of ZTEMODEM.ISO in a safe place - you might need it one day!
After the backup has finished, right-click "ZTEMODEM.ISO" and select "delete".
After the old ZTEMODEM.ISO has been deleted, insert this one (NEW VERSION August 2010) [mirror 1 - mirror 2 - mirror 3 - mirror 4 - mirror 5] by drag & drop (extract ISO from RAR first!). It contains the unbranded "ZTE Join Air" dashboard (version 1.00.0B02, English and German) with preconfigured settings for most German operators, a separate "Driver" folder with drivers (including installer DPInst.exe), MWconn 5.6 (an alterative dashboard) and MDMA 1.0.0.30a, a monitoring tool with USSD-support. Unfortunatley it lacks MacOS-support.
backup of original ZTEMODEM.ISO: ZTEMODEM.ISO from Vodafone K3565-Z (VMC 9.4.2.14731)
Wait until the new ZTEMODEM.ISO has been written to your device and then close QPST EFS Explorer. When asked wether to reset the device click "Yes".
That's it. Now your modem should contain the new dashboard.
