LG G2 D802 brick problem (I tried different solutions) - G2 Q&A, Help & Troubleshooting

Hello everyone!
I really hope I can find help here. I wanted to install Cyanogenmod 13 on my LG G2 D802 32GB. In the end I think I bricked my phone. I want to mention that I already searched for help on the Internet and tried many tutorials, but nothing helped.
First, I rooted my phone using this One click root method (before, I tried doing that other ways but it didn't work). So far, so good.
Then, I installed TWRP via Autorec. And here came the first problem. I booted into recovery mode and then the phone wouldn't start anymore. I started getting "Security error" along with Lg logo, when I wanted to turn on the phone. Actually I can't remember if I wiped everything in Recovery mode before or after getting this error, but I did anyway. Then I didn't get this security error message anymore, just stuck with lg logo.
Anyway I was still able to get into recovery or download mod, so I tried installing CM. But I couldn't acces my phone memory through PC and I didn't have CM installer zip on the phone. I tried copying CM installer into the phone using ADB push command. It did copy, it said it succesfully installed but since then every time I turn on my phone Lg logo just blinks for a fraction of a second and the phone will not turn on. The screen is black, but it remains "on" (there's nothing on it but you can see it's not totally turned off).
After that I tried every tutorial I could to install CM or stock ROM. I tried downloading different LG firmwares, including one found on a page where I had to enter my IMEI. But it's always the same problem: when I use LG Flashtool ( 1.0.54 ) it gets stuck. After clicking on System Upgrade I'm not asked about the language (as tutorials suggest), but it just opens LGMobile Support Tool, which says that my system is up to date.
OK, I think that's all I can say. So, the main problem is that I cannot use LG Flashtool, which is neccessary to install stock ROM in all the tutorials I have seen. Of course, I would like to install CM 13 still, but now th emost important thing is to get my phone to work again, even on stock system.
I hope we can solve this problem. Thank you all in advance!

Can you boot in download mode?
If you have download mode you can easily reflash stock

Thanks a lot. I followed the instructions in the first post on the first site that you linked, using kdz file. Everything seemed to go well and I was already happy, but... It seemed that the stock flashed (on the computer it said that the installation was correct, on the phone the screen showed Update Software and it went to 100% percent), then the phone restarted and started updating apps for Android. And that is normal I suppose. But then, after it finished, it turned off, turned on and started installing those apps again. After that it turned off. When I wanted to turn it on, it showed me LG logo and then android logo for a fraction of a second. Then sometimes it would turn off completely and sometimes turn on again and show logos again. I assume that's what is called bootloop. So I followed the tutorial which said I should do factory hard reset. I entered the screen (power+vol down buttons), confirmed two times that I want to do the reset. It said the reset will start automatically, but nothing happened. The phone just turned off immediately and the same situation with logos (Bootlooping?) appears. So the problem now is that I cannot factory reset the phone.

I'm having a similar problem on my vs980 except I can't access recovery anymore but everything else is the same.
Edit: I actually can access recovery

You messed up pretty bad before you fixed a problem, you created another.
Have you tried to go back to stock using downoad mode and kdz?

OK, well, this is strange. The phone is working again, but actually I have no idea why I downloaded the tool from your link, installed it and ran. Then, following the yt tutorial, I went to the step where I was supposed to "look and remember the disk number that have so many partitions". I didn't anything there, though. And then, all of the sudden the phone started updating Android apps and then turned on as after factory reset. Weird, but it's working fine
By the way, can someone post a link to a tutorial on how to install Cyanogenmod 13 on LG G2 D802 32GB? I would still like to install it, but I want to avoid all the problems that I had now. So is there any good step by step tutorial that I could use to install CM?
Anyway, thanks all for help

Sure.
Download the rom from cyanogenmod website and put it on your phone memory.
Download Gapps from opengapps.org and place on the phone memory.
Go to recovery.
Make a full nandroid backup( all the partitions) , wipe all except internal storage.
Flash the rom along with the gaaps zip.
Reboot.

OTA Bootloop Help

I have a Verizon LG G2 I tried to flash my backed up stock recovery with Flashify so I could flash the most recent OTA. After accepting the OTA update my phone restarted, tried to install the update, hung at a black screen but was still turned on. If I power it off and back on it shows the LG logo, some white text, then goes to the same black screen. What appears to be happening is that my backup recovery did not restore properly and it's hanging when it tries to go into recovery. It's almost like my recovery partition is blank.
I've tried to follow the instructions to flash back to stock, but I do not believe I'm actually able to get my phone into download mode. When it is plugged into my windows 7 computer with the LG drivers installed it shows up in device manager as QHSUSB_BULK.
Is there any way for me to push a stock recovery, or even a custom recovery to my phone so I can somehow salvage it, or am I permanently bricked?

I'm still trying to find a solution I will post here if i have any luck. I've dug through a lot of forum posts and I think what makes us unique is the fact that we have a corrupt or blank recovery partition.

Ive looked through a lot too. and its crazy how that would happen i made sure it was rebooting correctly before i took the ota and then when i did the ota bam! only screens i can get to come up are the hardware key control mode and the factory hard reset which both go to white screens after I do them both. every one else probably has not taken the ota.

One difference in what mine is doing and what your phone is doing. I go to a solid black screen not a white screen. It's very hard to tell my phone is even turned on. I'm having to look if the back-light to verify if it's on or not. I can hold my power button for 10 seconds through one LG logo cycle and then it turns off.

I hope someone helps us out. I really cant afford a new one because the warranty is void. I was going back to stock because of all of the little bugs that need to be ironed out in roms. cause kit kat is around the corner hopefully and my problem virtually is the same i might have had my brightness on auto or something prior to that.

After following the instructions on the above link i was able to get fastboot status on my phone. It did not fully restore my phone however. I was able to flash twrp via fastboot. I was then able to boot into twrp and run the command at this link via twrp terminal http://forum.xda-developers.com/showthread.php?t=2451696
Thanks to everyone for all your help.

Ignore all the message, unplug you phone get ready to type the command, plug it in and immediately press enter to run the command. it took some trial and error, and i had to use this other post to help me out. I actually got fastboot working first, then used this post to http://forum.xda-developers.com/showthread.php?t=2477595 to get download mode working, and to flash twrp recovery. After that i used this post to run the command line from with twrp. http://forum.xda-developers.com/showthread.php?t=2451696 . I didn't have to flash the factory tot to my phone, but i have that option now because download mode is working. This process will work, there is hope for you getting your phone back. I'm fully recovered. I decided 12B is not worth it in the mean time, but if you want 12B you need to flash the factory tot and then upgrade. There is a way to root 12B, but as of this time you are unable to get Custom Recovery on it.

[Q] Did I turn my G2 into a non-recoverable brick?

Good evening everyone,
I will start off by saying that I really didn't do things by the book this time around. I have run out of ideas even as to what to Google to find similar cases to mine.
I wanted to flash Cyanogenmod onto my G2. Since I already had CWM installed, I loaded the ROM and Gapps. After wiping the phone, I went to flash from the zip. The flash failed. I tried again, and it happened again. I wiped the cache and dalvik again, and tried again. Still no flash.
At this point I go for the reboot only to realize that my phone is now stuck in a bootloop that is contantly landing me back into recovery.
I believe I really screwed up from here as I read about a way to exit the cwm bootloop by flashing a new "exitrecovery.zip" file. Since ADP wouldn't push the file for some reason, I used that function where the phone waits the file to be pushed and flashes it. That succeeded.
The phone switched off (after hanging on CWM for a bit) and now won't do anything at all. No boot logo, nothing. Can't get into CWM anymore either.
The computer brings up a bunch off drives which it wants me to format when I plug the phone in. Only one of them has a folder called "image" on it.
The display switches on, but won't do anything there.
Holding power+up reboots it after a few seconds and so does power=down.
I am thinking of just seeing if I can get it assessed by my carrier, hoping they'll have the tools to just reflash it... somehow. Else, is there a way to potentially fix this?
Back to stock
Put the phone in download mode (vol up while plugging in USB) and use the LG Flash Tool to return to stock. Instructions are posted in General section.
Rule number 1.
ALWAYS MAKE A BACKUP.

I have a backup I made with CWM.
If that helps, please point me into the right direction to restore it. I fail to see how I can do that without even being able to start cwm up.

[Q] Entering Download mode while stuck in a bootloop

Hello,
this could be a silly question, but I'm actually hopeless about it...
I've been using CloudyG3 for 3 days, but I had some problems about it, so I decided I'd revert back to stock. I entered the Download Mode, installed the V20D ROM using LG's Support Tool, and, when the phone restarted, tried to enter the Factory Reset screen. Try as I might, I couldn't do that, so I'm stuck in a bootloop (I mean, the LED indicator is flashing, but no LG boot animation - just the static logo. I think there could've been some problem while flashing the FW, that's why I would like to enter Download mode again, or maybe at least turn my phone off (it can only restart). Nevertheless, while trying to flash the FW again while in a bootloop, everything from model no. to firmware version installed is shown correctly, but it can't boot into Download mode.
Thanks in advance!

Thanks for your reply!
No, I don't.
EDIT
I'm really grateful to you for your suggestion. Having plugged the device in, the Download mode came up with no problems. Now I'm trying to flash the previous version - V20B, which might make my device usable again.
Thank you very much!

HELP! I think I bricked my G2. No idea what to do :(

HELP! I think I bricked my G2. No idea what to do
I wanted to root my phone, which I already rooted before but then I made a factory reset and afterwards I got a root detecting app and it said my phone was rooted. But it didn't seem to exactly 100% work. I had downloaded superuser and I wasn't getting any prompts for superuser access when I tried to use apps that require root.
So I followed the steps in this thread to root:
http://forum.xda-developers.com/showthread.php?t=2784127
Install TowelRoot from here: http://towelroot.com/
Then install AutoRec from here for TWRP recovery: http://forum.xda-developers.com/showthread.php?t=2715496
Then if your staying stock I highly recommend you download and install SuperSU in recovery so that it's properly rooted. http://download.chainfire.eu/282/SuperSU/

Things /seemed/ to go smoothly, but after installing SuperSU from TWRP I tapped on reboot, then system (which I thought meant booting into the android OS, normally) but after the LG logo it went to a black screen with the LED flashing green and blue, and nothing happens... even if I leave it for like 10 mins nothing will happen. I tried lots of button combinations, long pressing the power button restarted the device and did the same issue, pressing volume up, down, and power turned the device off (thank god that exists) but there's nothing else I can do.
Btw my phone is on android v4.2.2, I never updated it to 4.4.2+ cause I heard that update has bugs and I was fine with my phone just working as it is.
TL;DR; phone is on 4.2.2, won't boot into android, after the LG logo during boot the LED flashes green and blue and nothing happens.
Does anyone have any idea what I can do now? Please help me I just want my phone to work again
Edit: Phone can go into download mode. But I have nothing to 'download' on it, what do I do now? Also I can access TWRP through the 'hard reset' thing (volume down and power button), and i tried factory resetting through it, but the phone still doesn't work.
I unbricked it, here's what I did, for anyone with the same issue
I went to this website http://sndeep.info/en and looked up my IMEI, which told me what country the phone was for.
Then I downloaded my appropriate firmware from http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/
And followed the steps in this thread http://forum.xda-developers.com/showthread.php?t=2432476 choosing a normal flash, not a CSE one.
Phone now works absolutely fine, hope this helps anyone who bricks their phone the same way.

[Urgent Help Required!] Phone boots, but no download mode or recovery!

Hi,
Have a weird situation, but try as much as I may, I'm unable to resolve it.
My phone is rooted (international D802) and was running fine. Had a screen issue and got it replaced at the service center but their system identified my phone as a rooted device, and a couple of days later the problems started.
The issues I'm facing right now:
1. The phone doesn't charge when switched on, at all.
2. The phone doesn't reboot either.. not instantly anyways. If powered off, or rebooted, the phone doesn't turn back on, it just goes dead. It does boot again though if tried after a couple of hrs.
3. The phone charges when its off (shows no light or indicator though, like its bricked)
4. Cannot go into either recovery or download mode. Coz the phone doesn't boot when restarted or when i try to reboot into recovery.
5. When it does magically start after a few hrs (upon long pressing the power button), even if I try to go into download or recovery via the vol keys, it just boots to android.
6. The phone is recognized properly as LG G2 under windows and all the drivers install too.
7. The phone isn't recognized under Linux... tried both Ubuntu and Knoppix.
Travelling out of the country in a few days, really need to sort this out.
Any and all help/suggestions will be greatly appreciated.
Thanks in advance
Somebody... Anybody? :'(
When your phone rebooted I would recommend you firstly to activate USB Debugging in the developer settings. You said your device is rooted? So try to install the Auto Rec recovery here
https://www.androidfilehost.com/?w=files&flid=13763 - but make sure you are on Kitkat. Now, install the app normal and let the app install all things. After installation, the app asks you to reboot to recovery, now press reboot to recovery.
Maybe you have luck and the phone reboots to TWRP. In TWRP you can go to Reboot and then Reboot to Download mode.
Now (if all worked) you can flash the stock rom .kdz file of the d802 via the FlashTool 2014.
Hope you have luck, please keep me up to date if everything worked.
Yours, Flo
Good luck!!
Thanks a lot for the response Flo, but the problem is that i never got around to updating to a Kitkat rom... the rom i was never got updated and I was kinda happy with how things were working so didn't jump on to any other rom.
Anything I can do in my current situation?
