[Sony Xperia T, TL, TX, V] OnionBoy88:
Too bad man, I tried as what you suggested. Downgraded the flashtool as you recommended and the firmware you suggested. The flashtool is able to flash the phone without any issue but my device still don't have any display. I will attached my log here for reference. I also tried study and found out Sony device tend to have display issue especially Xperia Z. Their solution is to let the device run out of battery totally and restart it again after full charge, I actually have tried that as well but have no luck too. At this point, I'm confirm my device have successfully flash back to custom rom but the display is very dim that even in a dark room you can only barely see the boot animation. But when you go into setting, you can't read the word even in a completely dark room. When i turn on the device, the led blink as green color and disappear right away. No Sony logo too....I don't think it is a hardware issue as the device is running fine before this until I flash it. :(:(:(

Hopefully some one will be able to guide me further here....
