hey guys i really need your help. here's the detailed story:
I've got a D855 on 5.0 that has just been recently been rooted. It's been working perfectly until just a few hours ago i wanted to try enabling the build.prop edit to enable all applications to be usable in split screen mode. so i just switched the related value from false to true, saved changes then reboot.
This is where the problem starts:
When trying to reboot, it just shows the LG logo briefly.. the LED lights just light up and switch from green to blue and loop over and over while the screen is blank.
I tried doing the factor reset on boot (power + volume down, release on power on then re-press again), but when i choose to factory reset the phone a short message on the top left appears ("Secure Booting Error! Cause : Boot Certification Error" - or something like that) then the screen goes blank and the led flashes from blue to red and on loop.
How can i go about making this thing work again?
Thanks in advance! Any help would be greatly appreciated
shameless bump
Can you get TWRP? If yes and have backup build.prop or ROM, flash it.
If not, can you get download mode? If yes flash KDZ.

You need to download a KDZ file for you D855 from a site or XDA thread
Then use the LG tool to flash the KDZ and then your phone should work as it worked before. I've had this issue before. Fixed it this way

thanks, yeah it was the only way i was able to bring it to life.. was able to fix it yesterday by using the TOT method.
Another question: it seems that after flashing the TOT file (i used the UK version), i can't enable LTE anymore. when i try to enable via settings, the signal just disappears. when i go back to the home screen, it gets restored but only up to "H/3g", and when i go back to settings it goes back to GSM/WCDMA.

You need to change your APN settings. Look on google for the LTE APN settings for your provider

Hi there, I NEED URGENT HELP!
I bricked my e739, and I am running out of the options. All I see is the LG logo, I can not access my recovery mode, I tried numerous times (and before i succeed now the logo doesn't even blink it stays the same) hard reset...nothing, tried adb recovery (does not see the device).
So here is the story, I successfully updated my ROM to e739 Nightly 6. After using it for a bit, I decided to go back to stock, and just wait until all bugs are worked out. So i tried to go back to my backup that I made of stock, but no dice it got me in recovery loop, after that I tried to go factory reset, nothing. I couldn't find any way to go back to stock, so I made it my mission to reset the phone. Here where I [email protected] up, I read that using e730 (older) rom will let me out this loop and allow me to get back to the stock. So here are my steps of mischief: installed Nightly ROM 12 for e730-> then I flashed the device to LG optimus Black (dont ask why...I realize it is stupid) -> and through privacy setting clicked for factory reset. Now I am in this bootloop.
I will take any suggestions please help, it really sucks in the stone age, with edge speeds.

Hold Power and Volume Down, then after 3 seconds hold Menu and Back (not home) and when the LG logo pops up, release the Power button but keep holding Vol-, Menu, and Back.
It may take some try a to get it right.

And make sure to pull the battery and put it in again when starting to hold the Power and Volume Down

This sounds like it might work, but O got another tiny bit of problem, I been trying to reset it so many time the phone wont turn on anymore unless it is plugged into power source. I am not sure what to do now. I want try to hard reset your way but I can get the phone to respond anyway unless it is plugged in.
Well plug it in lol
I've had several bootloops myself trying to get to stock, but i always got to acces recovery and flash CM again. And now that tthe RC was released, i don't see why i should return to stock.

1) Pull the battery out
2) plug ur phone to a computer (on the screen you should see a battery icon indicating the phone is charging)
3) locate your adb folder in my case it's c:\adb once your in there write adb reboot recovery...that should get you to the recovery....
good luck..

Hello, I have been having some issues with my LG E739[KW], the device was working properly. I rooted install CLOCKWORK custom recovery. After that I installed, CM9 then later CM7, the CM7 worked okay but i opted to revert to Stock So I used the LG SUPPORT TOOL to flash back to stock ROM. however after having done so the phone has been stuck in boot loop ever since. After flashing the stock ROM the phone never made it past the boot screen, and when I remove the Battery reinsert it and try to turn the phone on I get the S/W update screen. Where I have to flash it again for the phone to boot only to be stuck at the boot animation. I have also tried flashing it VIA the KDZ method but its the same result. Please Help !!!
I had to restart my phone and then it wouldn't turn on. When I turn it on it gets pasted the LG screen and goes black. The light is flashing green and blue. My phone is rooted too. I can see the battery life when I turn it off and plug it in. I have like 50%. I need help please.

Sounds like LGFlashTool is the answer. Seems your stuck in a pretty common bootloop that could've been caused by any number of things, most likely a faulty build.prop value possibly altered by an app with root access. If you can get in to download mode you haven't hard bricked it yet. If you can get into the factory recovery I would suggest trying to boot it in safe mode before restoring to factory. Also if you're familiar at all with ADB, try to see if your device is recognized during that black screen phase and pull everything you can save to your computer for later. Use the Restore to Factory TOT method about midway down the first post of this thread:
http://forum.xda-developers.com/showthread.php?t=2785089
Be sure to use that method for the Verizon variant.
Problem SOLVED!
Thank you all!
Hi ClarkOwen, would you care to share what happened and how to solve it? My Optimus G won't boot with red flashing led.
What rom are you using?
I tried to boot into safemode by turning on with power button + volume down button and holding it till it boot up then I uninstalled framework and gravity box as i think they are preventing my phone to boot up and then I rebooted my phone and it worked
What exactly did you do with your phone? What caused it not to boot up anymore?
There are senarios where you do get to restoer your phone using kdz but then it still wont boot up with red led blinking which basically means the battery needs to be hardware reset - taken out of the phone which would require you to open up your phone which is difficult. Thats why I need to know first what happened which prevents your phone to boot up.

Thanks for your reply. I run stock ROM and was preparing for flashing with CM11. I installed ROM Manager and updated my clockmodwork recovery. Then I boot to recovery when this disaster began. The phone just wont boot.
I followed the instruction found in this forum to unbrick using kdz updater and LGNPST and yes I needed to disconnect the battery first. Open up the battery cover was difficult but I managed to to it. After numerous attempts I managed to complete the step for both kdz updater and LGNPST but that still wouldn't boot the phone. Not even into recovery. I could get to the download mode though.
The last successful attempt with KDZ updater (successful means completed steps) has caused my phone totally dead. Now it won't respond in anyway. No flashing led, nothing. I suspect the battery could be dead.
Is it true that we can't charge the battery when the phone is (soft)-bricked?
Anyone knows how to charge LG Optimus G battery in the case of emergency? Ie. not through the phone? I read post about charging using stripped-out USB cable but I don't know where is the +/- of the battery.
Hi all,
Before someone says it, yes I did look around for other threads before posting one of my own. I was not able to find the problem that I am having, nor a working solution.
I am currently running CM12.1 on a Sprint G3 (LS990). This morning, I woke up and found that my phone had frozen while charging overnight. No problem, this has happened before, so I unplugged it and pulled the battery out and rebooted. It was working fine, and then I noticed an update for CM. I hit download, and went to go brush my teeth. When I came back, I saw that it had frozen mid-download. Now it wasn't installing anything; the CM built in updater was just downloading the latest nightly. I waited 5 minutes for it to become responsive, but it never happened so I pulled the battery once again.
Now when I held the power button to start my phone, I saw the LG splash screen as normal. After that, the screen went dark and the LED began blinking red and blue. No matter how many times I pulled the battery to reset my phone, this would occur. I attempted to enter Recovery mode, but in this case after the splash screen the LED would briefly light up blue, and then the phone would reboot, and the cycle would repeat. The same would occur when I tried to boot into download mode.
So now that I cannot boot into anything at all, I assume that my phone is bricked. It is still covered under the limited manufacturer warranty, and since I can't boot up at all I assume it doesn't matter that it is rooted, but before I contact LG I would like to see if anyone here has any ideas.
Before sending it back, have you tried to use the KDZ tool to restore it?

That requires the phone to be in Download mode, and it won't enter Download mode, so I have not tried that.
Well, this happened to me after I flashed TWRP from Flashify on my LG G3 D855 in the day before yesterday and I just had to take the battery out and put it back in, and then I had to boot into download mode. Since you can't even boot into download mode, I'm almost sure the phone is bricked

You HAVE to flash your phone if it was rooted or bump'd, otherwise, it won't be under warrenty, even if it don't boot, they're not stupid..
Every post have: "Your warranty is now void." in it for a reason.
Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.

Not sure I understand the question completely, but I did place the phone in download mode as per the method you mention prior to both attempting the KDZ method and the TOT method of going back to stock.
