How to Flash a MyTouch 3G
- 1). Locate the IMEI number of your phone in the battery compartment or by dialing *#06# from your handset. Write down the number for future reference.
- 2). Dial "611" on your MyTouch 3G to contact T-Mobile Customer Care. Explain that you would like the SIM unlock code to your phone. Provide the IMEI number you located in Step 1 and a valid email address to send the information to.
- 3). Turn off the MyTouch 3G when you receive your SIM unlock code by email. Lift the back cover off the phone and remove the battery from the compartment. Slide the SIM card out of its compartment. Slide the SIM card from the new company into the compartment with the gold side down and the cut-off corner facing out of the compartment.
- 4). Replace the battery and back cover on your MyTouch 3G. Turn the phone back on. Click "OK" when the phone displays a SIM card error message.
- 5). Type in the SIM unlock code you received by email from T-Mobile. Click "OK."
