I tried Yesterday Sony SUS and it cannot see the phone is connected??
Could please help me
1)Try to push the power button, if it will light red 3x proceed to next step. 2) open pc companion> support>repair>choose device model> connect device, just plug it in while holding the volume down until the pc companion recognized your device then release it, after finish try to boot up your phone, advise don't turn off your device again, if still unable to boot up after the repair, push the reset button at the back until it vibrate 1st(1 vibrate) 2nd(3 vibrates) then just leave your device in one corner for 2 days untouched, then plug in to your wall charger wait for 1 hour without touching any button then boot it up, i do this all the time on my xperia zl after every firmware update, I'm kinda sick of doing this but i need to, i still have 3 more month for me to go back home and get a nexus 5 as replacement phone, so disappointed to my zl, i love this phone allot!
I hope this works!
