My "Sony Xperia Go" does not go beyond the Sony logo on start-up. What is the problem?
The error indicates that the phone is stuck in a bootloop. To resolve it, open the PC Companion application and initiate the recovery procedure. The software will tell you all the necessary steps you need to take to factory reset or install the default firmware on your phone.
