Before you continue, do this at your own risk, I take no responsibility if you render your modem useless.
You will need 2 tools.
1) An unlock code generator based on IMEI, google this
2) T-mobile updater for UMG1831 (web connect rocket 2.0), download from Tmobile website, if it asks for number, type this telephone number: 6156680000
************Disclaimer************
I do not guarantee that your IMEI will be preserved, but if it disappears, follow this link:
IMEI recoveryInstructions:
1. Take a picture of the serial number using your phone, or write it down for easy reference.
2. Open the IMEI unlock code generator
2a. Type in IMEI number, press unlock

3a. Let it search and it will then tell you the following:

3b. A popup will appear, stating that the "the source version isn't compatible with the target version, before updating, please input the password"
3c. This is where you will need to type in the password generated earlier
3d. A disclaimer will appear giving you specific instructions to leave the modem, computer on and not to touch it till the upgrade is complete
4. Once completed a popup will appearing saying that IMEI number is: xxxx
