[Q] What does this mean?? (picture via link)

My LG L5 doesn't work anymore.
I can update the Firmware using LGMobile Support Tool or the KDZ updater but when i want to power on my device it won't start up.
It shows the LG logo and powers off. I cannot enter Emergency mode only Download mode.
When I plug the telephone in the computer it shows the LG logo, the computer makes the sound that something connects and then my phone shows this: https://plus.google.com/103349772149829538364/posts/ZCZb6QYgaFD

Could anyone help me please?

Search for a v10_downgrade.kdz file on the web, flash it and then flash the firmware that you want

Maybe your phone is discharged completely...

I think you have to replace the battery, the icon means your actual battery is completely out of service.

[Q] LG G2 D800 bricked help.

My LG G2 att variant would not boot after installing Grievous RSL 4.0. I believe I had the wrong twrp installed. I am stuck and cannot boot to android. I can boot to download mode but lg flash tools does no good because the model number does not match and says it is d802. Any help would be greatly appreciated. I cannot boot to recovery. I have only a black screen when not booting to download mode...
Check if you have adb access when you are on black screen.

No adb or fastboot access with the black screen. I have tried all night. Idk what else to do. I did the Linux option and now it says null next to imei and product number is blank when trying lg flash tool. For some reason I cannot get the lg launcher program to work either...

I know how to fix this, Ive got the same problem once before.
Download FlashTool.1.0.54, start UpTestEX and choose CS_EMERGANCY in PhoneMode in the top right cornor and take CDMA as type to the left.
And flash the right .kdz file for your model.
It will work. Cheers!

[NOOB] LG G2 hard bricked. Please help! :(

I have an LG G2 D802. I attempted to flash stock firmware on it and it went horribly wrong. Now, I can't even get into recovery or download mode and when I power it on it just has a black flashing screen.
I tried using this method but when I type ls /dev/sd* no big number sdb comes up.
When I plug it into my PC it comes up in device manager as QHSUSB_BULK.
I really feel like I am screwed and out of options now and just have an expensive paperweight.
Any help? Thanks.
[Edited] I've seen you already tried those method, for now I'm suggesting you to go to LG service center..

This saved my. I was stuck in fastboot with g2 as ADB modem in Windows.
No need for Ubuntu, works in win7. Try it. Not much to lose..

I think I might have made a little progress. I followed this guide in VMware Ubuntu and pushed the files to the appropriate partitions.
Now when I power on I see the LG logo and it goes to fastboot mode.

Is there anything I can do from here?

Its is bricked but luckily you can repair your Brock by using srk tools. There are plenty of videos of how to unbrick your phone using srk tools
