I have a LG G2 D802 and when I bought it, I rooted it and installed the latest official KitKat. But today, after receiving an OTA and accepting the upgrade, my phone is stuck in a CWM bootloop.
I tried several tutorials to restore a stock rom but none of them worked because the LG G2 is not recognized by Windows after installing the LG united drivers.
I also tried to use a generic driver so that I can connect to the phone with ADB but ... "adb devices" says "unauthorized device".
I also can't under download mode.
So I am really stuck.
Any help please !
