Unlocking Sony Ericsson T610

I bought a terminator dongle on EBay to unlock my SE T610 cell phone. The first trial failed since the software didn’t work on Windows 2003 Server. I got “Phone Not Power Up” error. Then I tried DIV4 from the instruction and got “Error 101”. I switched to my laptop and it worked nicely. So I unlocked the phone and flashed it with new firmware R4C003 US3 and Standard Modem R4C003. Lastly I un-branded it so it has the OEM version of everything.

During the flashing process, my laptop lost power due to used up battery:-( Luckily, everything was fine eventually. Now I have the latest firmware R6B and finally get rid of those “predefined contents” that I could not delete previously. The free memory is about 2.7MB now.

Laptop Internet Connetivity via SE T610 and Bluetooth

I have successfully configured my SE T610 via a Bluetooth USB adapter to connect my PC to the internet using T-Mobile GPRS.

Here’s my setup.

  • Laptop PC (Windows 2003 Enterprise Server)
  • Sabrent 2.4 GHz USB Dongle USB Adapter (I bought from AxionTech for $16.95 this afternoon)
  • Sony Ericsson T610
  • T-Mobile T-Zones Unlimited Plan ($4.99/month)

    Installation steps:

  • Install Bluetooth Software for the USB adapter
  • Pair the device (be sure to select a passkey to secure the connection, confgiure the services for the cell phone as bluetooth device, select Dial-up Networking)
  • Configure the Dial-up Networking (select PPP connection and set the phone number to *99***2#; no need to set up user id and password)
  • Add a new data account in SE T61o Connectivity/Data Comm (APN: wap.voicestream.com, CID will be 2. if not, change the dial up phone number according. The digit before the # is the CID number)
  • Click on T610 Dial-up Networking on PC. It should show connection up quickly if everything is configured OK

    I am getting 38 kbps through Road Runner Speed Test. Compared to 2655 kbps over a broadband connection. It’s very slow, but it’s fast enough for usage on-the-go.

    And it’s so hard to believe that I can use HTTPS on the PC while T-Mobile blocks HTTPS on the cell phone. It’s very hard to comprehend what T-Mobile is going after.
