I had LineageOS 14.1 ROM installed using TWRP recovery in Xperia L. A new update came through and installed it using TWRP recovery. Successfully installed with a message and just after pressing reboot, the phone went dead. The phone just gives a boot vibration nothing else. No SONY logo, no backlight, nothing. On connecting it to charging or laptop, it turns on red LED. On disconnecting the phone, the red LED remains turned ON till battery remove.Has the phone bricked? Please, any suggestions to help the phone boot up?
EDIT: It was a kernel problem. Flashed new kernel using flashtool in fastboot mode. Surprisingly, fastboot mode didn't worked before lol. Sorry for inconvenience. Remove this.
