Free Blackberry Unlocking: http://blackberryunlocking.biz
To unlock the Huawei D100 / D100T follow these instructions:
Download the firmware from the link above and extract it to your computer:
Before flashing make sure your computer and the Huawei D100 won't lose power during the process as it could potentially brick your Huawei D100!
Power on the Huawei D100 and connect it to computer through an Ethernet cable
Launch FmcUpdate.exe from the extracted files
Click the "Check" button to detect your Huawei D100 and shift it to update mode
Click the "Upgrade" button to start the update
Wait a couple minutes until the whole progress is accomplished
After upgrade, disconnect the Ethernet cable and push the reset button of the Huawei D100 (in the lower right corner of the backside) or restore factory defaults in the webinterface (open http://192.168.1.1 in your browser and enter "admin" as default password, then go to Advanced Settings | System | Restore Defaults | Restore).
note: If you do not restore to factory defaults after the update, your USB modem won't be detected properly and the "Connection" page will say "The USB Modem is nonexistent"
Connect your USB modem to the Huawei D100 port only when it's switched off!
Turn-on the router and go to the GUI by opening http://192.168.1.1 in your browser and enter "admin" as password.
To activate an access profile for your network operator, go to Advanced Settings | Dial Up Settings | Profile Settings and chose your provider from the Profile List. If your provider's settings are not included, just create a new profile by entering a Profile Name and all the other information required below and click on Save.
Afterwards go to Advanced Settings | Dial Up Settings | PPP Settings and make sure the correct profile is chosen in the Profile List. If not, chose the correct one and hit Apply.
Now your router is ready to share your broadband (remember that your USB modem must also be unlocked!).
You might want to enable (really) secure WiFi-encryption under Advanced Settings | WLAN Settings | WLAN Advance Settings where you should set WPA-PSK|WPA2-PSK as Encryption Mode and TKIP+AES as WPA Encryption. Lastly enter the WPA Pre-Shared Key, which should be not too easy to guess and hit Apply.
