Hello,
I have a Xperia SX with Android 4.0.3 and I wanted to upgrade to 4.1.2 but unfortunately I flashed wrong model and now it becomes a hard brick.
I don't have TA partition backup and it blinks read LED when plugging in USB without battery.
I found its testpoint and GND:

I tried S1Tool but I can't flash boot.sin downloaded with XperiaFirm with ERROR [ 0x0508:_sin_header_verification, err: 000A ] and ERROR [ S1_TA_Close,limited, err: 0010 ]
What can I do next?
