LG G2 Bootloop - G2 Q&A, Help & Troubleshooting

Hey guys my phone is stuck in bootlooop but first I will tell you how that came. I rooted my phone and installed cyanogenmod on it. I realized it was not what I wanted and a friend told me I just had to wipe my phone with Team Win Recovery Project and I will have my normal phone again. Well, I wiped my phone and now it keeps bootlooping. I tried adb with the commant terminal and adb sideload but nothing happens only my LG shows. I tried connecting it to my PC and getting a zip file on the phone which I could install via TWRP but my phone recognizes the phone without giving me acces to the personal data. Is there anything I can do or is my phone screwed?

[Q] D802 Bricked, computer won't recognize it

Hi,
I recently updated to the official 4.4.2 kitkat update.I then proceeded to root the phone, and then stupidly, installed CWM. I rebooted, and was greeted with an endless LG Splash screen. Now, I tried a HEAP of ways to restore to stock, all of them returning the same problem, my computer won't pick up my phone. In download mode, nothing happens, nothing in device manager, and same when I'm stuck on the LG splash screen. When I go into CWM, it then recogizes my phone, but the methods of restoring to stock won't work with CWM running in the background. CWM also won't let me mount the usb...
The methods return the same error: Phone not detected, please plug the USB cable and retry.
Ubuntu won't recognize the phone in all three modes, and another computer does the same thing. (Both Windows 8)
Methods of stock restoration tried:
-KDZ
-LGMobile support tool
-Ubuntu (This: http://forum.xda-developers.com/showthread.php?t=2582142)
Can anyone help?

Install http://forum.xda-developers.com/showthread.php?t=2588979
then go to recovery and try adb devices on command prompt on your PC to check if your device is listed
if it shows your devices then just search any thread that tell how to push flashable rom to your device.

Was your phone able to connect to the PC afterwards? I have a D800 that I am unable to get any PC to recognize. I need to restore it to stock but no matter what I do it does not show up in device manager (and I have a working rom on it).

Yes, it does work now. I was able to restore to stock by adb pushing phillz recovery, and then flashing that, then adb pushing the stock ROM. Everything works as it should, now.

Does it recognize your phone when it's in the custom recovery? That was the only way I could do it on my phone.
Good luck!
I tried ADB devices nothing came out.
I have the same problem as listed in this thread. Tried everything to SHort circuit the chip. Basically everything.
I think the last thing i haven't try is dump it into the bin.

[Q] Help with Bricked LG G2

Hello Everyone,
I've been looking around and can't seem to find any guide I can get to work.
A couple months ago, I rooted my LG G2 and installed Cyanogen mod successfully. After a couple days, for some reason I restored to a backup I made back before I installed Cyan, so it was just on the Stock OS. A couple days later my phone tried to update itself and it bricked it. I was an idiot and wiped everything for some reason so theres nothing on there but the LG logo and then it goes to TWRP.
So now I'm not quite sure what to do. I can adb push and sideload just fine, but I've tried pushing a zip with the stock OS and installing it but everytime it just says it failed. Ive also pushed cyan on again and it says successfully installed and then just goes back to TWRP again. Can anyone help me with what to do from here? Do I need a certain tool to re install the OS? Will pushing it and then installing it with TWRP not work?
thanks!

How would I go about flashing the stock rom?
Ive been trying to use this guide
http://forum.xda-developers.com/showthread.php?t=2432476
But every time I try to use the "Automatic offline procedure" I get an error saying permission denied. I made sure the drivers and everything were installed
Any ideas?
Right click - Run as administrator.
Or do it manually
https, window enabler..etc.
Alright, so I was able to do it manually, but in the instructions it says to enable usb debugging. Just to clarify my phone is basically stuck in TWRP, so will this even work?

That's ok.
Open cmd line where your adb is. Put some rom inside.
Let's say the rom is : mycoolrom.zip
adb push mycoolrom.zip /sdcard/mycoolrom.zip
then flash it.

I did this, but like I said in the original post when I try to flash it, it just says failed every time. Ive tried files from all over and they all fail. Could you point me in the right direction of one that might work?
Thanks
You didn't mention download mode.
Try powering off the device, hold volume up and connect to pc ?
Is the download mode at least working ?

Nope, no matter what I do it just goes to TWRP
And just to be clear it pushes over fine, and the zip is on the phone, its just when I try to flash it on TWRP it says failed. the last error code just said unable to open Zip

[Q]Phone can't get recognized by pc, download mode available

Hi,
yesterday I got d802 phone to fix it. First the phone was stuck at LG screen with certification error which I fixed. Phone was recognized by PC and i installed twrp on phone. I tried everything (i guess) and now phone is stuck at LG screen and it doesnt move. Now i cannot go back to twrp recovery but i can get to download mode but phone isn't recognized by pc so i cannot flash kdz file to phone. I'm really stuck at this point. Is this real hard brick or is there any way to fix it? Any ideas what should i do or something i can try?
I tried to plug phone in other computers and it's the same thing. My laptop recognized that something is plugged in once but it didn't know what was it so by now. Somehow from time to time phone doesn't go to download mode but it goes in hardware key control mode.
Hope someone can help...
So far i manged to get to recovery mode but adb sideload isn't working. I tried to wipe everything and that didn't help. As we speak factory reset is in progress but I think it's stuck on formatting cache. I hope I'll be able to get the phone recognized in download mode. Any suggestions are appreciated
I have made some progress. ADB is working now and i pushed cyanogenmod and on installation it says that it cannot mount data and cache. I think that main problem is that phone isn't rooted and now I'm trying to root phone via adb. If someone knows anyway to do this that would be great

[Q] Cant go back to stock by any means

Hello everyone,
So ive been lurking on these forums for some time now looking for a solution for the mess I just created, but its been so long now that I want to ask if anyone can help me out now.
The situation is I bought a LG G2 AT&T, and then proceeded to root, recovery and everything was flawless, but I tried to install another ROM and this is went everything went to hell (Im from Mexico). It went all black and with the "Fastboot mode activated" and stuff so I went an put it on download mode and tried by all possible ways, the LG Flash Tool and the LG Flash tool 2014, both ways do not seem to bring back my phone to life.
Whenever I try to install it like this, I get this error with the D800AT FW. I get this error.
And whenever I try to install with D802 FW. I get this one as well.
When I try with the Lg Flash Tool 2014 method. I cant get it to 100%, I always get stuck on 99% And then it crashes.
I am really running out of options here, the phone is recognized by the PC, but I cant get to install a normal working stock ROM.
Any pointers, or help, would be greatly appreciated.
Thank you.
EDIT:
Apparently, I cant post images just yet to show you the exact error. But for the first 2 errors, I get something like this.
"DOWNLOAD FAIL! Check phone or DLL" both for D800 and D802
If you have twrp as your recovery you can adb sideload a rom onto your device from your computer. Google how to sideload adb with trwp installed and follow the instructions. If your phone is recognized it should be fine.

First of all, thank you for your response.
Now, it is still recognized, but I tried to flash it with some DLL a guy provided on this one thread (http://forum.xda-developers.com/showthread.php?t=2663369) and it didnt complete, it just froze on 94% and now I cant get to Download mode.
I saw about the adb sideload, but I cant seem to access to Recovery now. Tried to, but all I get is some kind of bootloop just showing the LG and android with the open belly and then back to LG.

So the three finger method only gets you the android with the belly up? Is your phone still recognized? I'm on Verizon but i think with other phones it's the same process. If you have no recovery you need to tot back to stock. I've only done it once but it did work. This is what i used to fix my problem when adb didn't work. Lots to read but it does work and people will answer if you have a problem http://forum.xda-developers.com/showthread.php?t=2797190.. Good luck man.

If I try to enter Recovery I enter the stock one and just asks for a Factory Reset... I can not enter download mode now, I get fastboot mode only when I try download mode. Phone is recognized by computer when I connect it, but when I try to enter Download, it does show the device on device manager, but it sounds weird and I cant do anything.
Im really starting to lose it.

If you see hit enter for factory reset (white screen) hit yes. It will enter the recovery. Twrp in this case. If the above program doesn't work but you can get into twrp download a full stock att rom... Download koush's universal drivers (google it) and watch this video at 4:20 he explains in english perfectly how to side load a rom.

You need flash required partitions (like aboot and laf) to boot phone to download mod. Then, you can install stock ROM from LG Mobile Support Tool.
You should take a look at here;
