[Q] AT&T LG G2 D800 hard brick-please help

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

[Q] Bricked D802, Any help?

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_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.

Verizon G2 Bricked! Demigod Crash Handler! No Nothing!

I was going back to stock using the KDZ method and USB cable came unplugged during the process. It gets the secure boot error and is stuck in the DemiGod Crash Handler. Computer only recognizes the COM and Modem. NO ADB, FASTBOOT, DOWNLOAD MODE, RECOVERY, SAFE MODE, NO NOTHING. Anyone have the same thing happen?

Plug into your computer via usb. Open device manager. If you see qhsusb_bulk then follow this guide to fix. Unfortunately I didn't get that therefore there is no fix...However I was very grateful because Verizon let me get an early upgrade. I now have a G3.

Well bro I was stuck with the same issue..
This happens to me when i flashed a wrong twrp recovery for lg g2 d801 and it was stuck in critical error i was also unable to access download mode ..
But my Good luck was that i recovered it by doing silly thing ?
So i do following things. But make sure u know the corrert version of your lg g2 to flash kdz file with lg flash tool and also must have lg drivers intalled.
Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode

Secure boot error after reverting to KitKat via TWRP backup

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

LG G2 Demigod Crash Handler when go into recovery.

I have an LG G2 D802 International, that for the past 2 weeks wasn't working well,the application android.home crashed so the phone was unusable, I tried rooting and installing a custom rom but I didn't manage to install a custom recovery on Kitkat, so I decided to hard reset it, after that I finally decided to upgrade to Lollipop from Kitkat, then I decided to root the device and install a custom recovery. The problem is that I rooted the device, but I tried to install a Custom Recovery via Autorec and it didn't work, so I tried Flashify and now if I go to Recovery I got this

, if I go into download mode I can't flash anything, LG Flash Tool 2014 crashes after I select the Language.. Now the difference between my problem and the others is that I can still manage to go into Android and use my phone normally, but I can't go to Recovery and flash anything into Download Mode! Please Help me, I really don't know what to do.
Sorry if I did some Grammaticals errors, but I'm Italian and I hate translators.
If someone knows how to restore the basic recovery that will be fantastic, and my phone is branded Vodafone, if I wanna switch to the OPEN firmware without all the things from Vodafone I can just do it by flashing it with the LG Tool?
Help me, the OS rebooted and now it's a continue bootloop, if I go to Download Mode it appears as a black screen and on the pc pops out like 30 disks, help How do I unbrick the device?

Have you checked your phone model by removing back cover or on imei.info ? Make sure it is actually a D802 version coz it is common in lg phones that what it look like is actually not ☺
I also bought a used lg g3 and was happy to have an open d855 due to fake rom installed in it but in fact in real it is sprint ls990.

Having the same problem with a d800
I can still boot in to Android, and gent into download mode, but I haven't test download mode yet, I would like to change te recovery to twrp so I can flash a costum ROM, is there a way of installing another recovery even tho the original recovery seams broken or something?
