Hello, I'm new to this forum, and like every newbie, I'm asking for help.
My problem is this:
I bought a LG G2 D802 32GB, it was rooted and with CMW. I intalled LG Mobile Support Tool and it appeared that there was a new firmware (apparently 80220C) so I installed with that software, but when it finished, the phone restarted and got stuck on the LG logo. The only thing I could do was to get into Fastboot mode and from this post: http://forum.xda-developers.com/showthread.php?t=2477595 I managed to get into the Download mode (That one with the Firmware Update message: btw it appears: "USER B100 ROOTED"), the thing was that I didn't know which exact version of 80220B had my phone, so instead of getting the laf.img mentioned in the thread (the one of cms88168 was 80210B), I used one named: "Europe OPEN D80220B_00". In that way I managed to access Download mode. I then proceeded to use LG Flash Tool 1.8 (Used first 2014 without sucess) both from: http://forum.xda-developers.com/showthread.php?t=2432476 and this message appears:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
BTW, I used DLL: LGD802_20130912_LGFLASHv160.dll
And the rom I extracted the laf.img was a KDZ (Europe OPEN D80220B_00.kdz), the one I try to install with the LG Flash Tool is a TOT (BIN_LGD802AT-00-V10b-SEA-XX-SEP-04-2013-32G+0.tot)
Please, if someone can help me to fix my phone (I've only had it for 10 days, no way to return it), please.
Thanks in advance and cheers.
UPDATE: I used the DLL from the KDZ file and the same TOT and the LG Flash Tool (v1.8) reached a higher status in the update but failed with this message:
And now it gets stuck in the "Download Mode" screen and in Device Manager theres is no track of the phone.
I don't really know what to do.
Why don't you try with kdz ?
Here
+ you took the ota or ?
Hi, thanks for replying.
All this happened because I updated it connected to my PC.
I tried that and it throws this error: "Problem with communication between cell phone and PC"
The phone won't enter in download mode and when I turn it on, stuck at logo and connect it to PC, it appears like this: "LG AndroidNet USB Serial Port (COM41)" -41 set by me.
Is there a way to access the phone through COM to restore partitions?
No adb or fastboot working.
What can I do?
Hello, I want to update the info about this post:
I definitively had to return the phone for refund.
Now I own a Z2, it's a great phone, although the G2 is a great phone too.
If possible, please close this thread.
Cheers.

I have an AT&T D800, and my stupid ass flashed a D802 rom. Now I assume the build.prop in the phone is D802 instead of D800 and the LGFlashTools recognizes it as D802. There is no way to get it to go into recovery mode. I've seen a lot of posts about being stuck in fastboot mode, but I there's no way for my phone to get into that either. I assumed that if I could get it into fastboot mode, I can do something about the build.prop. I have seen some people who did this exact same mistake within threads, but there are no solution or follow up to the issue as far as I have seen. Is there just no where to get it back?
Thanks.

okay so it may not be as bad as you think as long as you can get into download mode(volume up and plug into pc) you can use a custom dll from here http://forum.xda-developers.com/showthread.php?t=2483043(go to downloads and get the dll(what it does is that it skips the model check so make sure you flash 10d, 10o, 10q or 20c for the d800)) you will be able to flash back to stock d800 firmware using this http://forum.xda-developers.com/showthread.php?t=2432476
p.s. I've read that the only easy way to get into fastboot mode is by flashing a corrupted kernel just to let you know

Hey everybody! Please, I need urgent help!
So, yesterday, I upgraded my G2 D802 from rooted stock KitKat to the official European Lollipop, v30b. Before that, I made a TWRP backup of everything.
So, I rooted Lollipop, installed TWRP, and was about to install the new Xposed for Lollipop. Then, **** started freaking out and "LGSmartCover" kept crashing continuously, making it virtually impossible to navigate the UI.
Soooooo, I decided to revert back to KitKat via the TWRP backup.
Everything SEEMED fine, but now I cannot boot. I get the LG logo, then this message appears:
ERROR : boot certification verify
[800]_______________________
[850]
[900] Secure booting Error!
[950] Cause : boot certification verify
[1010]

I do not seem to be able to enter download mode or recovery either.
My computer does recognise it as "qhsusb_bulk" when plugged in, though.
What do? I'll be eternally grateful if somebody can help me solve this.
UPDATE: I somehow managed to get into this "Hardware key control mode" by pressing and holding all three hardware buttons at once, while plugging the phone into the computer.
UPDATE2: Somehow, I managed to boot into Download mode, after doing the same thing over and over again! Trying to recover via LGMobileSupportTool now..

same error
How did you solve it ?
Hi,
I had a similar problem and I managed to repair the phone by using the TOT method with LG FlashTool v1.8 by reaching download mode.
Good luck!
If you can fully enter download mode(first screen and then the second screen),then try to flash a stock rom with LG Flashtool(KDZ method) or TOT method.
Since you were using TWRP,official LG Update tools will kill your phone if you try to flash the stock rom with them.
i have the same problem and i dont know how to reach download mode. when i connect my phome to the pc, it shows the same secure boot error. any help?

Supposing the drivers are installed in windows, you need to have the phone plugged in to comp. and then hold volume-up+power until you get the "download mode" on your phone's screen

I had the black screen problem, followed that tutorial, but I still didn't get back download mode, till I had an idea, turn off the phone for real, then try to access download mode. As G2 doesn't have a removable battery, you have to remove the back cover and unplug the battery pin (there are YouTube videos teaching how to do that), wait about 30 seconds, replug it and try to access download mode as usual.
But i have apropblem that the phone shows 13 local drives when plugged in, one of them is 63.9 mega and consist an image folder with 79 files. Now i lost qualocomm 9006 and ir shows on. Communication ports qhsub-bulk

I had the same problem as you, a lot of drivers. I followed that tutorial to get back Download Mode, then used that procedure I've told you to access the Download Mode.

I'm connecting the LG G2 D802 to the Windows 7 in download mode, with LGMobileDriver_WHQL_Ver_4.0.4.exe drivers installed, however the drivers fail to install.

Unidentified device
Install drivers manually and disable windows update to override whatever windows wants to install from there...
The issue was happened when trying to flash some LG G5 adapted rom on the LG G2, so the bootloader or the recovery got damaged. What I finally did was to force qhsusb_bulk short circuiting the capacitor and then using SRKtool_2.1_droidth.zip to use the unbrick method.
Then, you can reboot to download mode to use LG Flash Tool or reboot to recovery to flash the partition of your particular rom using dd (once you upload the partition images to the smartphone sdcard).

Hey scandium, I know it's been years since you've posted this,
but I was wondering if your phone symptoms were unknown device on any pc+slow charging with any charger. I currently have a G2 in this situation. It works, but has no USB connectivity whatsoever, and takes ages to charge. Do you think that shorting the capacitor and flashing the phone from scratch would fix it? I'm afraid of trying it and when connecting to the PC still get the unknown device problem and end up with a brick. Thanks in advance.
