nb: sorry for bad english
so when i want to unlock bootloader, right before when my devices want to reboot, suddenly, flashtool won't detected my devices because my USB cable were dislodged from pc. and my xperia m bootloop. and i'm re-flashing again with FW 15.4.A.0.23 and so bootloop is gone. but the problem is, my xperia M won't detected any signal from my sim card, but before my devices bootloop, my xperia m can detect signal from my sim card. so anyone knows how to fix it?
