[G2 Q&A, Help & Troubleshooting] limafoxtrot:
Bricked G2, I'm worried I'm out of options...

Ok, I think I need some help…

Just got a LG G2 for my wife (wedding anniversary). It arrived by post yesterday, yay I though, I got a couple of weeks to sort it out. Am trying to transition her from her old iPhone4S over to Android, and from checking things out, it looked like the OptimusG3 rom was the way to go, in terms of a nice interface.

I shoulda slowed down and been more meticulous with the process, but anyway… I have little knowledge of these things, but have managed to flash custom ROMS to a couple of devices before (HP Touchpad, Ainol Fire), noting that any problems I’d previously encountered were usually due to skipping or not following steps properly.

G2 model is D802. Kitkat 4.4.2 installed by default.

Tried to follow guide here http://xdaforums.com/showthread.php?t=2788077

Tried to root as per here http://xdaforums.com/showthread.php?t=2448887

I think the root went through ok, although I had to try more than once (had other stuff happening in the background so not paying 100% attention).

Tried to flash TWRP as per here http://xdaforums.com/showthread.php?t=2633941

Didn’t seem to be able to get this working.

Uncertain at this point if I was properly rooted, so redid it with https://towelroot.com/ - which seemed to be fine

Then tried to install TWRP with Autorec: http://www.droidviews.com/install-twr...

Which seemed to be successful, and I’m sure I picked the D802 TWRP recovery file, but THIS IS WHERE THE TROUBLE REALLY BEGAN - on reboot to recovery the trouble started – no logo, I’m just seeing a black screen with vertical lines that change for a bit, then go static.

Turning off and on -> black screen/white lines

Turning off and on + holding VOLUME DOWN button -> black screen/white lines

Turning off and on + holding VOLUME UP button -> black screen/white lines

Turning off and on + holding VOLUME UP button plus on/off button a couple of times at about 10 second intervals (trying to guess what the download mode screen prompts are) -> black screen/white lines.

When plugged in to computer, device manager shows ADB device and no modem. No G2 showing up in devices, either with and straight ON/OFF or ON/OFF plus VOLUME UP.

LG MOBILE TOOLS cannot find my device. I’ve tried downloading both G2 and UNIVERSAL G2 drivers.

LG FLASHTOOL 2014 cannot find my device either.

I’ve tried to follow hard unbrick guide http://xdaforums.com/showthread.php?p=48765620#post48765620, set up a portable Linux distro on my laptop etc., but at the [ls /dev/sd*] stage don’t get anything beyond [/dev/sdb1]. Trying [gdisk -1 /dev/sdb] with all the options available gives me a blank – i.e. no directory structure as per the guide.

I though, Ok, ADB is in the device manager on my Windows OS, so maybe I gotta go through ADB. I found this guide http://theunlockr.com/2013/11/03/flash-custom-recovery-lg-g2-versions-video/, but at the [ADB PUSH] stage, there is no device found again.

I’m not sure whether to call this a hard brick or not. It looks like the display driver (or something similar) is messed up, but I still do have a display (albeit one that I can’t read). However, trying to go to DOWNLOAD mode doesn’t get me a “LG” device, and even the ADB device that shows up doesn’t seem accessible.

Any thoughts would be very welcome!!! [i.e. HEEEEEELLLPPP!]
