[Q] Stuck in CWM bootloop after upgrading from OTA

Lex008 · Jul 7, 2014

Hi

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 !

I probably made the situation just worse, when I tried to install TWRP and CM11 ...

Now I have : "Secure Booting Error! Cause: boot certification verify" and after 10s, the screen goes black.

I can't connect to the phone from USB anymore. It is seen as "QHSUSB_BULK"

Since your in qhusb_bulk mode you'll need to follow this guide to fix it.
