I own WT19i from more than year. Last months I was using LegacyXperia 10.2. And everythingwas working flawessly. But today phone become dead... I was using it normally and left for 2 hours on the desk. Battery was fully charged. When I come back phone didn't react on any button. So I pulled out the battery, then putted it back. Still nothing. Trying to charge - nothing. Trying with other battery - nopthing. Trying boot to flash or fastboot mode - nothin. I've tried with 2 different batteries, 2 USB cables. Still nothing. It seems that phone is completly bricked but I can't find a reason.
Any ideas what else should I dp?
