I've just downloaded Kingo Android Root and after some minutes my Moto G 2nd generation soft bricked and now stays in the Moto logo forever.
Since I don't know anything about how to root a phone with safety, I simply didn't enable USB debugging before installing Kingo app. Also, I don't believe this app indeed rooted my phone.
I only managed to unlock my bootloader and that's all. I tried to put the XT1068 firmware.zip file in my SD card in order to apply this update from the SD card but it didn't work. Moreover, when I run the command "adb devices" on OS X, nothing shows up. But when I run "fastboot devices" the prompt returns "0010235101 fastboot".
And of course I tried to wipe cache partition and data, but it didn't work either.
Any suggestions of how to solve this problem will be welcome.
