Hello ... my story a little problem ... I unlock the bootloader , install a custom- karnel , root and all perfect ! 15.3.A.1.14 received the update , the download and install flashtool wanted to try to solve few hiccups ... the problem was when connected to the pc in Flashmode only the green LED is lit for a few seconds, turn off and nothing happened , from that moment on, try conecterlo the wall charger and the same thing happens and green LED turns off, the pc Coneto and achieve to recognize it as a USB input device while another device as defined by the HID compliant provider ( as 2 different devices ) and if I connect and I hold the keys precionado volume up and down is connected as Qualcomm HS- USB QDLoader 9008, pass 30 seconds and reconnect as the 2 devices ... it is clear that attempts to repair the software with Sony PC Companion and Update Service but enters as Flashmode I could not do it , I can not connect in fastboot mode .. try to be as clear as possible thank you very much beforehand ! hope can help me . sorry for my English , I'm Argentinian
Because you have modified software from rooting and custom kernel then PCC and SUS will not work - You could try using Flashtools and a .ftf firmware file and manually flash a stock rom however over on XDA it is known that flashing kernels may cause your phone to become hard bricked meaning your phone is only good as an expensive paper weight
no possibility of repair
If Flashtools doesn't work then check on XDA other than that I'm afraid not
when I connect, flashtool tells me Device connected with USB debugging off devices line, be sure you are not in MTP mode
You can try flashing with USB debugging off - You won't be in MTP mode or doubt you will have been - But if you have been flashing custom kernals etc then USB debugging would have been switched on
