Xperia M dual stuck at boot screen after unlocking bootloader! Help needed it's urgent. So I have unlocked bootloader successfully via fastboot.
Everything went fine until the end without any error. So I disconnected the device from PC and rebooted it and now it is stuck at boot animation forever. It's the only phone I have now. Any suggestions?
I've solved my problem for myself by re-locking the bootloader and then repair the device using Sony PC Companion. Device is again in mint condition ;)
I'll add a supporting link later.
