i have a Sony Xperia V with locket bootloader from Yoigo ( spanish carrier) i used the xploit to install recovery clockwork mod and root the phone , then recently i wanted to update to 4.3 , i donloaded a zip with the 4.3 and flashed it from the recovery , then the phone didnt start , it got stuck at the beginning ( with black screen) , the update service and the pc companion didn't work , so i used flashtools , putting my phone into flashmode before flashing a ftf file with the original rom from my carrier in the 4.1.2 version. after that , the phone finally booted , but here's where it gets weird , my screen locks as if it was broken , weir colors , ,and a big square around the borders. what can i do to fix it if anything at all can be done.
that's how the phone turns on , then the sony logo appears , very pixelated , and then the phone works normally , but with weirds colors and bars in the square.
my phone is Sony Xperia V and what i flashed was http://forum.xda-developers.com/show....php?t=2683958 in zip from the recovery
