Hi guys,
I am trying to go back to stock, while entering download mode, I got the screen shot that tells about Firmware Update.
(see attachment). The progress bar stuck at 0%, I have to unplug the USB cable and press power button on G2 for about 10 seconds to reboot again.
Is this normal, or there are something wrong? Also, my pc, Win7 64 bit failed to installed G2 as a USB modem, but success to installed it as a USB serial port.
Thanks in advance.

Hi, I was flashing my LG when the flashing tool stopped at 63% and showed some error, i tried to flash again but it gave me error 502.
I turned off the phone and tried to turn it on again, the screen wont turn up but the PC detects the LG (zune doesn't).
I've tried to put it on emergency download mode with vol- + camera + power but the tool stills says error 502.
Is it recoverable or is it lost?
Update: I was able to recover it! I tried to enter emergency download mode with the battery out but connected to the pc, then i inserted the battery and the LG flashing tool recognized it!
Took 5 minutes to flash it. (I used the vol- + camera + power to enter emergency download mode).
Good to know and happy for you resolving your issue

Hi.
My phone stuck on boot. But when I plug with an usb cable to my pc it detects for 17 secs and in this short time the kdz tool cant detect my phone
BATTERY OUT.
VOLUME DOWN + PLUG USB CABLE phone will start in emergency mode now flash KDZ.
You also can try by following the instructions cited above but pressing volume down and up at the same time.
I own an LG G2, i recently got this phone yesterday from a person on craiglist. Don't worry i didn't pay him i gave him my older phone i dont use anymore. SO This phone is practically stuck in Firmware Update (As i read that post) , i spent about a day and half figuring it out and what happens is that.
I CAN get into recovery its TWRP v2.7.0.0 by Turning off the phone first and then Holding Vol UP, Power, Vol Down at the same time until the LG Logo comes up and then i am still holding them down, and it says Recovery Mode please wait and bam TWRP.
But heres the problem i can't mount my OTG and i can't ADB Sideload. So what do i do from here?? this guy rooted this phone and soft bricked it i think? and he wiped the phone but i also did when i had the chance and wiped it completly via recovery.
The only way i got into "Download Mode" / "Firmware Update" was to take the back cover off and unscrew a few screws on the side and unclip the battery for a few seconds and then plugged it back in and then I held the VOl UP button and plugged my USB into the phone and the other end is in my PC. My phone says "Download Mode please wait" and then prompted with the Firmware Update screen. BUT my pc doesnt detect the phone whatso ever and i've already installed drivers and etc from this forum ( http://forum.xda-developers.com/showthread.php?t=2432476 ) its the 2015 method that i downloaded.
so what do i have to do, i havent tried using different usb cables, the port seems fine to be plugged in since in TWRP it says 84+ so i meant its charging right? help me out guys idk what else to do or flash or anything.

I think the methods leave out that you need to change your phone to com port 41 on device manager > ports in order to be detected. Then you need to unplug it and reconnect to computer when the program shows waiting for device, with the phone in download mode already.
Also, to get to recovery you hold vol down and power, when the LG logo comes up release power and hold it again until the reset screen comes up.
To get to download mode you turn the phone off then hold up while plugging the USB cord in with it connected to pc... This launches download mode.

Well you see man , I cant change anything in Device Manager since my phone isn't being detected. It didn't install drivers fully fully since my phone isnt recognized. Even in TWRP or "Download Mode/ Firmware Update" Nothing happens no drivers installing or anything even but it does boot it up to that point....and its just normal boot up i see the LG logo and my led goes from green to blueish in a smooth transition and it doesnt stop until i turn it off. The method i got into recovery is holding all those buttons down its not a problem for me to get into it. I also have another problem it doesn't seem to want to mount my usb otg by samsung.
what do i do
So i tried the otg route but I can't mount it. I have everything connected and once I go into recovery to mount usb-otg, nothing happens.
I just need some way to get a ROM.zip in my phone
Computer does not recognize my phone.
Stuck at LG logo unless I enter recovery.
Sideload doesnt work.
OTG doesnt work.
I've tried at least 4 different guides with no luck.
Why don't you manually install drivers from online?
ive tried

ive tried that already and it doesnt list anything from the LG folder.
I realized the phone will say start the adb sideload feature. so, when i put the "abd sideload file.zip" command on my pc i just wait a few minutes and it says daemon not running on port 5037 and then start successfuly and then error :device not found.
it can seem to reognize my device wether its in recovery, or download mode or fastboot mode.
Try again in other pc that has never been conected to an LG Phone before. It can perfectly be a conflict with drivers installed in the OS.
I've tried man
AFter i cleaned the usb port in one of the chats or forums, i waited a day ovbiously without turning on the phone and cleaned the usb port with alchohal and a q tip and i plugged my phone into my computer and my PC detected something but it only says "Unknown Device" everytime no matter what pc i use it says that. nothing else. but before that none of my pcs would detect theirs a phone plugged in at all.

No there is no problem with your USB cord or port. You need to do following steps.

Hi,
A friend of mine gave me his LG Spirit H440 with the boot error: Secure booting error
In his words he tried to update the software, the phone started to lag and after a reboot the error occurred.
The guy is simple user so installing custom recovery or rooting are out of the question.
Here is a video I made of the problem:
https://www.youtube.com/watch?v=fONioh6uNms
After removing the battery the phone starts for 2-3 seconds with Secure booting error and then powers off. After that it cannot start again until the battery is removed and then everything repeats.
I tried to connect it to the PC with Windows 8.1 and installed LG drivers, but nothing happens. It's not recognized.
Also tried to enter download mode with Vol Up and connecting the USB cable, but again it just displays the error and shuts down.
Is this soft or hard brick? I'll be grateful for any help and guidance.
Try to set it in "upload mode" and flash stock rom kdz

how did you solve this crappy error??
No I didn't manage to find a solution and no one was able to help me.
I returned it to my friend and he bought a new phone.
Sorry.
1. Power down the phone.
2. Connect USB cable to computer.
3. Hold Volume DOWN and insert the USB cable.
4. ??
5. Profit.

im sorry for ignorance but FastBoot=Upload mode?
Same problem, is there a BOARD DIAG option for this phone?
Hi everyone, I try booting into EDL mode both using the button combo and the adb reboot edl command, and both just freeze the phone. I'm given a black screen that doesn't respond to button presses or plugging into the charger, and I have to wait for the battery to die before it'll start charging, after which I can turn it on normally.
My PC says 'USB device descriptor failed' when the phone is in this mode, even though when it's turned on normally I can transfer files over and whatnot just fine. I've used different cables and different PCs with the same result. Anyone know how to fix this? My main objective is to root so I can get rid of ads system wide. Thanks
Did you figure out how to fix this? I'm having the same problem now, didn't have it before.
