Unlocking the Huawei D100

I recently got a Huawei E5 with a Globe Tattoo subscription. Although I can easily share the Internet connection to my wireless devices, I needed my PS3 and Linkstation to share the connection and be accessible from my wireless devices. Supposedly, the E5 can be used as a USB modem. But when I plugged it to the USB port of my Huawei D100 router, it wouldn’t work. Next, I removed the Globe SIM from the E5, put it in my unlocked Huawei E1550, and plugged it into the D100. No luck either. It seems I need to unlock my D100, too.

Luckily there is a way. After a quick search, I found this: http://3g-modem.wetpaint.com/page/Huawei+D100,+D100T. From the site:

To unlock the Huawei D100/D100T follow these instructions:

1. Download an update from above and extract it to your computer:
2. 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!
3. Power on the Huawei D100 and connect it to computer through an Ethernet cable
4. Launch FmcUpdate.exe from the extracted files
5. Click the “Check” button to detect your Huawei D100 and shift it to update mode
6. Click the “Upgrade” button to start the update
7. Wait a couple minutes until the whole progress is accomplished
8. 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”
9. Connect your USB modem to the Huawei D100 port only when it’s switched off!
10. Turn-on the router and go to the GUI by opening http://192.168.1.1 in your browser and enter “admin” as password.
11. To activate an access profile for your network operator, go to Advanced Settings | Dial Up Settings | Profile Settings and chose your provider from theProfile 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.
12. 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.
13. Now your router is ready to share your broadband (remember that your USB modem must also be unlocked!).
14. You might want to enable (really) secure WiFi-encryption under Advanced Settings | WLAN Settings | WLAN Advance Settings where you should setWPA-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.

I followed the instructions and it worked like a charm. So now when I’m home, I’ll be on the D100+E1550 combo and when I’m on the go, I’ll be on the E5.
