So i turned off my z1 and turned it on again so i can boot into recovery. But no green led light flashed. It booted straight to my home screen. Tried restarting again but still i cabt get into recovery. I tried flashing stock kitkat firmware but still nothing. Factory reset and sril no avail. Is there a way to install a recovery without root? Im currently on lollipop 5.0.2. Thanks
