LG G3 D855 not booting, LED fading blue-green - G3 Q&A, Help & Troubleshooting

Just got a D855 from a friend, she told me it wasn't booting and thought the screen broke (not very tech-savvy).
I somehow got to the point where it cycled between green and blue light on the LED, and managed to copy some files from /sdcard/.
I know the screen isn't broken because I saw the LG logo once.
I tried to boot into downloadmode, it just shows the box for a split seconds and disappears instantly.
I really have no idea what to do, anyone please help!

Try running the flash tool anyway. It worked for me.

[Q] brand new g2 screen issues - lines down screen??

I JUST got my LG G2 from sprint less than 4 hours ago and as soon as i got home i rooted it using ioroot25 that i found somewhere online (if its important i can dig up the link but figure its probably irrelevant) and installed TWRP recovery, made a backup, not a single issue, then all of a sudden half hour later i pick it up and turn it on and the screen is mostly white with yellow lines (that move/respond to touch and whats supposed to be going on on the screen) and it will not show any sort of picture just kinda yellow fuzz lines...it looks just like some phones ive seen with cracked/ faulty LCDs but if i hold the power button and up or down to hard reset it, the LCD starts working again upon boot, and continues to work untill the LCD turns off for the first time after booting and i try to wake the phone again, every time i turn the screen on when its on it goes back to fuzzy lines with no way to make it start working other than restarting the phone with the buttons on the back.
anybody ever seen anything like this before? it cant be a broken or cracked lcd cuz when it first boots it shows a crystal clear screen and everything works fine untill the first time the screen turns off...im guessing i am more than likely going to end up making a trip back out to the sprint store tomorrow for a manufacturer defect replacement? any insight into this strange problem would be greatly appreciated!

Any suggestion/help ?

[Q] LG Optimus E975 Security Error

Hello,
I badly need your help guys. My sister accidentally uninstalled an important file on my LG E975 and now, its not booting up. I'm getting a Security Error.
I looked for a solution and found out about KDZ method. I was told to charge my battery first but when tried, it seemed not charging. What should I do? Thanks..
It should charge... Aren't you getting the charging screen ? (when your phone is off and you connect it to the charger, it doesn't boot, there's a different screen), don't you have it?

Thanks for the reply. Yes, Im not getting the charging screen. After turning off the phone and connect it to the charger, what happen is. It automatically turns on, flashes the LG logo, then it shows Security Error with LG Logo, then it goes the same thing over and over again..
I don't really know a solution but I would leave it like that for like 2-3 hours and then flash the kdz..

it seems you got the bootloop problem thats LG's problem with hardware.. so you can try going back to stock, read carefully in the general for how to retrieve your data.. and you must sent you phone back to get fixed... would you mind sharing your first 3 digits of your serial number..

Well i got a similar problem with yours earlier this month. I was browsing on Facebook and it suddenly hangs on me and kicked into a restart and never got pass the boot logo since (at least in room temperature). Then i realised i got the problem most people with this phone had, bootloop issue. As per searching on the internet, i found that there is a slight hope of backing up my data by putting the phone in the freezer, which i did. Guess what? The phone boots up and i manage to backup all my files (while it's in the freezer). Once it's out of the freezer and went back to room temperature, the nightmare repeats itself and i have to send it in for repairs.
I'm just sharing this just so if there are people with the same issue as i had could have at least backup their data off the phone.

There are only a blue screen

In some cases a blue screen means kernel issue, you can try reflashing with KDZ following the instructions here http://forum.xda-developers.com/showthread.php?t=2785089 to see if that solves your situation

Lg G3 suddenly went permanent black screen.

Hello all, this happened recently today.
My phone just "shut off" into a dark screen and pressing/holding any buttons does absolutely nothing. I've plugged out the battery and tried to power it on again but it would do the boot screen then straight into a black screen.
I've also tried different batteries but that had no affect either.
The phone does not connect to my computer also.
Currently about over 2 years old, 5.0.1 i believe running the dragon root (i forgot the name but the post had a purple dragon i believe?)
Have you tried Download Mode?? If phone shows the LG Logo then I guess you have a change to enter download mode and recovery with a TOT or KDZ

I've tried going into download mode, but it went straight into the blank screen again. Would it still be in download mode?
the problem happen to the hardware. i think its Emmc card.

Try that
Maybe it was a short circuit. Has your phone reached high temperatures to overheat? Have you tried replacing some parts or sending it to a specialist? Your problem is probably a hardware error.
According to you say you can not enter recovery, download mode, or load, based on all this an old g3 that I had, had the same defects and take it to the technician and told me that the motherboard had melted in some sectors, can Be that it happened to you.
