Hey everyone,
We have an LG G3 D855 here which has been interrupted midway through flashing a KDZ file,
Powering on the device gives us,
"Cause : Boot certification verify (secure booting error)"
Followed by the screen going off and the blue red LED flashing endlessly.
Download mode does not work,
Recovery mode does not work,
However, the factory reset screen appears, but when selecting yes it reverts to the LG logo and reboots.
Here is a screen shot of what appears in device manager on my PC after I attempt to enter download mode.
As you can see, it is "QHSUSB_BULK" in device manager.
We have tried adapting this guide for the G2 with Ubuntu, but the device is not recognized by Ubuntu. http://forum.xda-developers.com/show....php?t=2582142
If we can get into fastboot somehow we will be fine, but nothing seems to be responding. Any advice would be fantastic.
We also have another idea, of super hard bricking the device somehow so that we can follow this tested method of getting out of the brick,
http://forum.xda-developers.com/lg-g...s-usb-t2933853 not sure how to get either of these though so some help would be great.
The same problem has been described here, http://forum.xda-developers.com/lg-g...-mode-t3003988
