Today when I was reflashing my LG G3 D855, I accidentally installed the 32GB version on my 16GB Phone. It went up to %3 but then my phone stopped working and I restarted it. Now if I turn it on there is: No Download mode, No Recovery mode, Secure mode error LG detected as qhsusb_bulk in device manager When I boot my device it shows only LG logo with secure booting error, then the screen goes black while your phone is still on. I have read this article on another forum which its address is: http://forum.xda-developers.com/show....php?t=2582142 But the only difference is: my phone is LG G3 and it is NOT rooted. When I run " ls /dev/sd* " on ubuntu I got no drives/partitons as my Smartphone. And when I run " sudo lsusb " with my phone connected, I get: " Qualcomm, Inc. Gobi Wireless Modem (QDL modem) " But I don't have access to partitions of my LG G3. And if I disconnect the phone I won't get this line. I think I might have deleted some of those files explained in that article.
