D800 Boot Certification verify - G2 Q&A, Help & Troubleshooting

i have an LG G2 D800, sometimes when i plug it to charger it turns on for a few seconds and shows the boot certification verify error along with the LG logo, then the screen goes black and cant do anything, pc doesnt recognize it.
i tried going into download mode (hold vol+ when connecting to pc) but nothing happens, sometimes it just turns on but show again that Boot Certification verify error and then the same black screen... Pc doesnt recognize anything (not even that qhsusb_bulk in device manager)...
what can i do?

Can you get into recovery? I literally had that same error today.

no, sometimes when i make the vol- and power combo, i get the white screen with the yes/no option. then i select Yes and get the LG logo with the error, and black screen again

am not sure basically going into download and flashing TOT. maybe you need to short motherboard.. check the thread no download no recovery in my signature look for it there.

I know exactly what you are talking about hmm...
I was gonna suggest if you can get in recovery you could flash another rom and the problem would be solved, but its different in your case. You said your computer doesn't recognize your phone as well? I would assume you have the proper drivers for your device.
If you are able to get into download mode I suggest you use this guide: http://forum.xda-developers.com/showthread.php?t=2432476 to get back to stock..
I am not sure why you aren't able to get into recovery, but that's my suggestion. What did you do prior to this error popping up?
If all else fails then I would contact LG and try to convince them to send in your phone for repair, just a thought.
I've done a motherboard replacement on my G2 and in that case it was totally hard bricked. It is not a motherboard error so you would not need to go there.

go into download mode and use TOT or KDZ and flashtools. good luck
you said AT&T d800? i used this.
http://forum.xda-developers.com/showthread.php?t=2663369

Okay, heres the thing
I was able to short motherboard and got 9008 mode, used the BoarDiag method and it installed everything. But now, everytime i try to boot into download mode, phone does get into download mode but shuts off after few seconds.. So i cant install ROM from LG Flashtool, what now?
edit: now everytime i disconnect battery, connect it again, and connect it to pc or wall charger, it stays for a moment at LG logo and turns off, but cant seem to get to download mode... tried disconnecting batt and connecting again, then hold vol+ while connecting usb and it stays again awhile in LG logo, but no download mode, it just turns off again...
edit 2: Well, now it doesnt show Download mode for a few seconds... if i keep pressed power button for aroun 30/35secs and connect it to pc, it just shows LG logo for like 10 seconds and turns off, nothing else, not even doing the power button thing and keep vol+ when connecting...

okay, heres the thing now:
i used BoarDiag with d802 files and could get to download mode to flash d802 firmware TOT. it boots to lg logo and shuts down after few seconds.. then i tried the same with d800 TOT, and it does the same...
with d800 TOT sometimes it flashes an android green logo with some loading lines under it for like 3seconds and shuts down

Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.

In case you did the latest firmware ota upd,there is a topic that can solve you problem as long as you can access TWRP(even if you didnt do the ota it will,i tried that myself) Here is what you need to do.
use TWRP's "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
This will probably fix you problem when it has to do with any update.
Thanks for the responses. I finally fixed it.. I started the procedure from scratch with a new laptop and somehow it worked lol

It happened to me and now phone hanged in download mode and can not connect to pc. Did you have a solution?
Solve
Guys! I had the exact same problem today. My solution was to keep pressing the "try again" button every time the error appeared on my computer screen. It took some time but the error was appearing at different levels each time in this order : 45% 57% 65% 80% and next the instalation was completed. If it doesn't work try switching to another computer if you can. After the firmware update hits 100% your phone will restart and the LG logo will appear(the led changes its color during this process). At this point you have to just wait a while. Then a dialog box will appear saying that the applications on your phone are configuring themselves. After that your phone will start and work normaly. The cause of the error is the lack of memory on your phone. If those idiots working for LG would say "YOU DON'T HAVE ENOUGH STORING SPACE" this stuff would not happen.
The phone is not rooted!(IMPORTANT)
Phone name: LG G2
Phone model: D802
Old software: 4.4.2 (KitKat)
Actual software: 5.0.2 (Lollipop)
I hope this hellped you solving the problem.

Download lg flash tool.
Download lg g2 stock firmware.
Press volume up button and insert usb cable. You will see download mode.
Open lg flash tool and flash the kdz( original firmware) through flash tool.select cse flash.
My LG V20 got stuck on the Firmware Update screen. It appears every time I restart the phone and I have to take the battery out. If I start the phone plugged in it starts normally. I was able to do a factory reset, the phone started normally a few times without being plugged in, now it's back to the Firmware screen. I can use the phone but need to restart when it's plugged in. I hope Oreo Update will fix it. I don't know much about updates, but do big updates like that reinstall the drivers as well?
Hello everyone I also have this kind of experience so many times in my g2 mini.stuck on Firmware update. What I’m doing is,
1. remove the battery to turn it off. Plug your charger and before plugging it to your phone hold the volume down and plug in until tou see the android is updating; or
2. Just simply hold the powerbutton + volume down until you see Android is updating.
I would love to see your feedback if it helps.

make sure to have lg driver installed on your pc
press vol- and connect your phone to your pc, (else try vol+ + power + home and connect your phone to pc)
run KDZ and flash a new firmware
I'm sure that i have installed it... When i try the CWM recovery key combination, it shows me only the LG logo but not disorted like on normal reboot... I also tried to go into Modem Download Mode (Vol-, USB Attach) but it doesn't really work...
I also wanted to repair it by ADB Make Easy... but as i read somewhere else, to make it see my phone connection, i have to turn on USB Debugging... but i can't because i can't boot it :/
New thing... If I plug it into pc without a battery then it is connected (still cant see it) but it turns off after 1-2 minutes... ah and something else... If i plug it in, it shows me only the loading logo, nothing else... please help
I forgot about emergency mode combination and it workes! Tomorrow i will start flashing kdz. Thank you for your help. I appretiate it

try to go to download mode.i think when your device has a problem like this it put it self to fastboot mode.if it stuck in fastboot you can flash download partition using
Code:
fastboot flash laf laf.img
I tried that. Pc doesn't detect my phone. It says waiting for device.
I gave it to warranty anyway. Let's see what they will do.
Thanks for the reply.

[Q] Flashed wrong kernel!!!

i Was trying to get rid of the hissing noise on my
Lg g2 D802
i had TWRP installed
I read in a trhead that flashing the dorimanx kernel should fix that problem.
So i tried flash it, but instead of flashing the D802 i flashed the D800, i know i'm an idiot :/
I had a backup stock kernel but i think that's a wrong one too, again i'm an idiot
Now my phone boots into a black screen within the left top corner:
[2800] Fastboot mode started
[2850] udc_start()
i cannot boot into twrp anymore, it's basically bricked.
Can anyone help me recover my phone? i loved that thing, you will be my hero.
i promise when this is resolved i will never mess around with roms and kernels ever agian, i'm freaking out

Try to flash back to stock with kdz, as far as I am hearing this you kinda soft bricked it but not hard so it's still recoverable, you could also maybe try to flash your recovery back with fastboot since your in fastboot mode but I never tried that so I suggest you to go back to stock with kdz flashing
ye try enter download mode and follow this (use search) i think its volum up and connect usb to pc

Thank you for your reply, i tried to get into download mode, but failed every time, i can only press the power button for 5 sec and the Lg logo apears, then i get the same screen.
did this way?
Your phone must be turned off before starting the steps from this guide.
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
Now the phone will install some drivers – it should take around 10 minutes to complete; the best will be to let your device install the mentioned drivers.

I did the same thing today by accident. I still can boot into recovery tho, TWRP. Copied the correct kernel file via OTG but it just reboots the recovery and doesn't install the kernel. Have you find any solutions?
EDIT: I actually managed to flash the right kernel and the problem is now fixed. Check everything before flashing something guys, caution

LG V20 Device is Corrupt and BootLoop

Hey all! Hopefully you can help with this issue. I have had this phone through T Mobile for a few months now, and am stuck in a real bind. As the title suggests, I have a boot loop issue and Device is Corrupt issue as well. The red Triangle is an issue with the OS. I cannot get the phone to boot to Android, nor get into recovery. I can however bring up the IMEI menu, which displayed the IMEI. I really need help, as this is my main contact for job search and family.
Im on sprint so this method is unavalable to me.
Tried LGUP? you have the ability to shoehorn a KDZ file in whicj will bring your phone to stock
As this is a no go for the ls997 i have no idea how this is accomplished. Check the forums for said method.

I will definitely look into this. I just want my phone back TT.TT lol
I wanted to chime in, I've got the same issue as OP.
What's broken:
turning the phone on normally - displays an LG logo; gets stuck, won't proceed past this point
holding VolUp while connected to PC - displays IMEI; won't enter download mode
holding VolDown - displays IMEI; won't enter fastboot or recovery mode
So, there's no way to get to recovery. I'm stuck with a $400 brick that displays a logo or an IMEI number.
LGUP w/Uppercut doesn't work either, shows up as an unrecognized device, and it wouldn't matter if it were recognized, because I can't get the phone to download mode to restore a stock .kdz.
I just ordered the phone on the 4th from Amazon, so I'll see if I can return it/get a replacement, but I'm guessing I won't be that lucky. It does display the orange "WARNING: Bootloader Unlocked" screen, meaning it's very easy to see that the warranty has been voided, so I guess whatever support I get is a crapshoot.
Again, since I can't get to fastboot mode, there's no way to restore to stock and relock the bootloader before returning it. Kinda dug myself into a hole here with no other options.
I got it to install! Now to just play the waiting game and see what happens. I had to do some finagling to get it to work, but it works.
I found a H91810 KDZ, I started Uppercut which loaded LGUP, click on UPGRADE, then selext the KDZ file from where you saved it. Should work. Also make sure all of your drivers are up to date.

Ok, I seem to have my device back up and running. The step I was missing was to remove the battery, disconnect the USB cable, put the battery back in, hold volume down but don't press power, instead connect usb cable. This got me into fastboot and I was able to recover from there.
this might work for you!

okay so holding VolUp while powered down and plugging into pc will bring up download mode if its still there,
if you have twrp installed prior to this red triangle then pull battery/put back battery. hold VolDown and power at the same time, as soon as LG logo comes up release power button (fast) and then hold it back down again while never letting go of VolDown. this is the factory reset hit yes for both questions and it should reboot phone into Recovery mode. some times you have to do it twice to get recovery (twrp) to pop up! i hope you have bootloader unlocked and twrp.

If using the LGUP you must get the G4 Dll file for it to read the phone and com its on. i believe its a common.dll file i cant really remember...

You can put the phone to download mode (even if screen displays glitchy gibberish screen) by taking out Battery first, put battery back in after 10 seconds. Then just press Vol up and while keeping it pressed, connect to USB. If you have drivers installed, your phone will get recognized by LGUP. Now from here you can flash the stock rom.
