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?

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.

Ah nice. Unfortunately I can't get device manager to see mine at all so I can't even ADB .

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.

Hi, sorry to post in this 1 year old post buy mt G2 is totally dead, I can sometimes get LG Logo and the main problem is i cannot get it into QHS-USB mode or anything.
Is there any key combinaison to do that ?
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!
Reflash lg g2 stock rom .
Sent from my GT-I9300 using XDA Free mobile app
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
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
Hello XDA,
I stupidly put my G2 in bootloop. It is 802, 20h, stock rom/recovery and rooted with ioroot.
I managed to break it by removing the LGweather.apk and LGslideaside.apk from system app because I was tired of seeing them taking memory for no reason. After a reboot, it is blocked at LG logo.
I have made a nandroid backup some time ago through an app so I have those APK on my computer, I just need to put them back with adb.
I can get it to download mode (picture here http://forum.xda-developers.com/showpost.php?p=58181792&postcount=4), but I can't get adb to detect the device although I tried many drivers.
My question are: Am I losing my time by trying to have adb work or it is a driver problem and it will eventually be able to push the file if I can have the phone recognised by adb?
Should I try the hard reset offered through the keys combination? I am very much afraid it would make it worse as I changed many things in the phone through xposed.
Thanks a lot in advance for your help.
Flash the SAME rom via lg flash tool (choose normal mode because it doesn't touch your files)

Well I would have prefered not to, but as I couldn't get adb to work and the hard reset only brought me back LG sound when bootlooping, I had to.
It worked wonderfully, thanks. I have to try to get root back now (even if it shows as rooted in download mode).
The rooted is more like cosmetic
I recently bought a LG G2 for a great price, when I got it back to my home and turned it on, I discovered something. I found that it wouldn't boot and Download Mode is REALLY BROKEN. I can still get into TWRP, but the UI is in ruins and I can't navigate. When I try to enter Download mode, I get used to get an error code. Something like: error: cannot verify download mode, or something like that and when I try for a normal boot, I just get stuck at pixelated display. Really what to get this phone working, I can't disassemble the phone and I don't have the tools nor money to get said tools. When I power it on, I get an extremely pixelated display and I don't see the LG logo anywhere when I boot it up. I have been able to get the logo to appear once or twice. There is no warranty on this phone, can't afford to send it back to LG. I am getting very stress out over this device.
Things/Methods I have tried:
1) I tried to enter Download Mode, but it 'crashed' per se, and it then proceeds to wreck my PC, by flooding my display with Windows Explorer pop-ups.
2) Tried a normal boot after I restored my previous ROM before this stuff began, and it did no good.
3) Tried to get into fastboot, but apparently, it doesn't seem to exist on it, so I can't use other methods.
4) I downloaded the appropriate KDZ file for my phone to try and flash it back to stock, but the LG Flash Tool didn't recognize my device. I attempted to try and use the Minimal ADB and Fastboot tool, but it didn't to anything for my phone. Everytime I entered a command, it's say "<Waiting for Device>" and then it'd proceed to freeze there not do ANYTHING.
5) Tried a normal boot and that did nothing.
6)Tried using the ADB Sideload feature in TWRP, but that proceeded to crash the UI even more and then the device would freeze.
7) Wiped the Dalvik, System, Data, and Cache and then attempted to restore the OS, but then when I tried to get it into the the OS, it'd just boot loop at the pixelated 'boot screen', if that's what you'd call it.
8) Tried to get into fastboot, through Minimal ADB and Fastboot, but nothing happened.
9) Tired to fix Download Mode, but then the error arrives and then the device proceeds to a completely black screen.
10) Contemplated on physically removing the G2 from this plane of terrestrial existence.
I would appreciate the help. I want to get this phone back to Stock Firmware and then use it as my primary device and sell my Moto G.

First verify model number of the phone viz D802/ D803/ 802T. Download original firmware file and Flash appropriate bootstack, download bootstack from https://github.com/lg-devs/bootstacks here.
After flashing boot stack, connect phone with cable to PC.
Use key combination (depending upot the bootstack you choose) to boot into download mode.
Use LG Flash tool to flash original firmware file.
You are good to go!

Download your recovery for your model, try flashing in TWRP if you can, then flash correct ROM for your device *Link*http://www.gregtwallace.com/lgg2-projects/twrp/?version=2.8.7.3
first thing you should do is to know if phone was refurbished, some phone claim to be d802 and they are not..
you do this by opening phone and checking MOTHERBOARD model or variant.

I don't understand how I can flash the boot stack when I cannot connect my G2 to my PC and it work. When I put it into 'Download Mode' I get an error and it crashes, then a bunch of unformatted drives appear and I can't use a flash tool, because my PC doesn't detect that it is connected to the computer.

I can't get anything into the TWRP recovery, I am able to get into TWRP. Outside of that, I can't do much. I can restore my back up, but both of them were post-crash and I can't do anything. I tried the ADB sideload, but it wouldn't launch the file. I enabled MTP (Media Transfer Protocol?) but I didn't see my device.
