Xperia Mini/pro :: Black Screen On Booting Up: Not Rooted, Stock ICSOct 26, 2012
My phone doesn't boot up. This has been happening since the last 2 days. The first time it happened, i used Update Service and updated the firmware to the new 4.1.B.0.587. The phone restarted normally after the update but the phone was very laggy. And after sometime, the same issue popped up. The phone would start up to the black screen. Again I used Update Service to do a factory reset and reinstall the new firmware. Formatted the memory card too. Again this issue is there.
I called up Sony Customer Care. They asked me to use PC Companion and repair the phone software. I did that too. Still no luck..
