I recently bricked my phone and flashed my firmware to fix it. I'm now in the lg welcome setup page where it asks your language . I can't press next or any button. It's like the screen is not collaborating . Tap on doesn't work or tapping out. It's an LG G2 D802-20C model and that's what KDZ i used. I flashed with LG flash tool 2014 with type "CDMA" since there is no GSM and CDMA was recommended. . Any suggestions?

Hi there!
So I rooted my LG G2 (D802, 4.4.2, Stock, used ioroot) yesterday.
I intend(ed) to flash the Optimus G3 Rom, in the start post they recommended to flash cmw/twrp via "Simple Tool 3.2" (http://forum.xda-developers.com/showthread.php?t=2633941). After doing so (I used the automated version, not the manual one) I got STUCK ON THE BOOTSCREEN. There is a notification popping up for a few seconds in the left upper corner which lists several errors occurring:
BOOT CERTIFICATION VERIFY
SECURE BOOTING ERROR;
CAUSE: BOOTCERTIFICATION VERIFY
along with the following numbers listed from top to bottom: 710, 760, 810, 860, 910, 960 (I just noticed, the numbers can vary, but always follow the same pattern...)
after this message, the screen fades to black, I think it it is still running though, since it takes more than 10 seconds to reboot the phone by pressing the power button. I still have access to the button down/power button combo which leads to a factory reset setting, but it doesnt do anything for me since I still get stuck at the lg boot screen.
I
Atm I dont what to do! Enter download mode and flash something? I'm seriously kind lost here. So, thank you for your help!
Cheers
You flashed a custom recovery version thad doesin't match you phone ( example you flashed D801 recovery on D802 phone )

Thanks a ton!! Finally I can put a name on the problem (bricking...)- Ironically I never mangaged to get there in 3years of samsung flashing but got there within 15mins of flashing on the LG G2. I guess it's true what they say about samsung devices, as hard to brick as a brick...
I'll report back if it worked...
Weeell, as it turns out my phone isn't recognized by my pc (Win 7) anymore...I literally can't do anything. Any hints?
I can use the Tool, but it's always trying to connect to my phone without success. But when I connect my phone to the computer it opens a dropbox window (import photos) and several windows partitions, which it tells me to format...

LG G2 32GB D802
After bought I upgrade firmware from V20B to V20F using LG Flash Tool 2014. Ater flash new firmware the phone don't respond for touch. When I tried change laungage and touch example english(us) hi select other language, when touch any one of 3 buttons(arrow back, home, 3 lines) hi display: "Unfortunately, the process android.process.acore has stopped" and screen is frozen-no access to any phone settings. Phone is completly crazy: when I touch "back button" the phone select 2 diffrent buttons.
Option Recovery Mode(power button&volume down) are not available. The download option are available-I tried lot of times,again,again flash the firmware(ROM) but with negative result. Also I flash to stock ROM with negative result.
No access to any phone settings.
Any idea for resolve it?

My LG d802 phones touch screen has broken. It has been replaced with all new screen. In the same time, I get 5.0.2 v30b update. Now knock on(double tap screen on) is not working. But screen off working well. I updated touch firmware at the hidden menu , I flashed same Rom 5.0.2 v30b and I formated with hard reset. Still not working. Is that a software problem or hardware problem. Should I make root or flash another roms . maybe new screen doesn't support knock on?
I think its because of proximity sensor.

Hello,
I've used this for my LG G2 802
Go on phone call, type 3845#*XXX# XXX is your model, 802, 801, 805.....
After in the hidden menu, go in Settings, Update Touch firmware, wait 5sec because your touchscreen is inactive, lock the phone and the knock on will work.

I did it already . but it didn't fixed
I am having the same issue. I Replaced the screen (actually this is the second time I replaced it. When I replaced it the first time I did not have the problem) and now knock on does not work any more, but knock off does.
I updated the touch firmware and checked if the proximity sensor works fine (in the hidden menu). I also re-installed dorimanx 10.7 and set it to default, but nothing helped. Anyone has an idea what to try next?
hey, my lg g2 D802 was bricked now and don't worked youtube video about lg flash tool 2014
then i downloaded the latest version of lg mobile support tool
then it said that i have the latest android
solution is next. you must click Options and then choose your country
after that you must press also Options and then Upgrade Recovery
after that you must wait download time and finish time and everything will be ok, as i am happy now
before that you must be in download mode. i mean turn your lg g2 off, press long time power button (for power off your phone) after that press volume up button and plus connect usb to computer together
just i am so happy to survive my lg g2, it was bootloped
but there is different version of stock rom, and wi-fi don't works, but i did reset now (from settings) and everything works fine
thanks for attention

Hello,
I have a LG G2 LS980 and i have a touch screen dead zone problem. I mentalized i buy a new screen to replacement and now i'm wating the new screen.
The problem is i can't try touch screen firmware update because when i enter at the hidden menu, is incomplete, like the image at the attachment. Doesn't appear the settings to go to the update touch screen firmware.
Any idea?
Solved
I resolve the problem (hidden menu) with a program called Shortcut Master (Pro Version), but the touch screnn firmware update doesn't resolve the problem.
