Answer to: My xperia x10 mini froze on startup screen how do I un-freezeok here is how you fix this problem. this works coz i have fixed mine! go to sony ericsson website and download the SERVICE UPDATE to your PC. INSTALL and RUN......CONNECT USB TO PC (NOT PHONE) after installation it will ask you to HOLD BACK BUTTON WHILE INSERTING THE MICRO USB INTO PHONE. FOLLOW INSTRUCTIONS CAREFULLY The service will download the latest software version for the phone and install it to your phone too. wait for the message that tells you its safe to disconnect the phone...do so and turn back on with sim and memory inserted and ur handset will turn back on and run good as new!!! Hope this helps and good luck!!
