well after i succesfully brought back my d801 from the dead because of a hardbrick demigod crash handler: critical error and then a whitescreen shows off, using the SRKtools i was able to have download mode again, but then after i boot up my device it only shows the lg logo and the led flickering about 5 seconds and then it shows an android with his jelly open and a red triangle of exclamation i think this is because i don't have any system preloaded
so i try to install a kdz with flash tools but everytime it keeps stucks on 2% and then it doesnt go any further
so i was wondering if any of you could have a solution for this problem thanks a lot and regards
Hi
Look in step 5 in this thried http://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033
The stuck at 2% mostly occurs when phone charge is below 30%.Charge it to full and try to flash kdz again .else try tot method.

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.
My lg optimus exceed 2 will only display on screen firmware update which is froze the phone won't do anything Please Help! !!!!

Hello
I can't access my LG g2 after trying to wipe the system and it runs on frozen screen. Kindly help out please
My LG x power died and I went to plug it in and a screen popped up saying,"Firmwire Update 0%", so I kept it plugged in for the next half an hour, and it still said 0%. I've tried resetting it and powering it off but nothing seems to be working. What do I do?

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.

I had the same problem...
1. So first you have to turn the phone completely off.
2. Then hold down the volume down+power until the LG logo is shown, let go and then immediately hold down same buttons.
3. This will bring you to a reset screen. Go through the reset process
4. This will bring you to the recovery
5. I installed a backup or try installing a rom you have on the phone
If any questions just ask. I know how stressful this could be

what is KDZ EMERGANCY MODE?
When you are unbricking it through the method that didn't work for you there is a KDZ Emergency mode that you can check. When I had the same problem as you did I just did the method that I posted above. Not sure what will happen if you do use the KDZ method.
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.

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

But when using Flash tools it hung up on the yellow flash button. I have no clue what happend. I try to start from the beggining but it wont complete like it did at 1st. So im stuck with the 4 color boot to fastboot. Wont connect to ADB so i cant sideload or recover from ADB in recovery. any help plz. i just miss my zenfone 2 ahha.
so in recap:
It wont flash fully in Flashtools 1.14.
Wont FW+OS complete in the downloader tool(only FW finishes)
No recovery mode options like it disappeared
When i let it boot normal it says updating with the android guy for 30 seconds then goes to dead guy with error.

Hi friends !!
I've a problem. When i power up my LG L Fino (D290N), i give an error "ERROR: Boot certification verify" and after shutdown and black screen.
I've tried to flash kdz file, previously downloaded, and i can't access to Download mode giving same error like normal boot. I'm tried to use ".tot" file and same problem, i can't access to download mode too.
I don't now how i can resolve this. For this reason, please, i ask for help.
Thank you very much to all users.
