Ok, so I flashed cleanrom ex, and on reboot I got a security error.
I tried to get to recovery, but it wipes data and immediately reboots.
I've tried flashing the stock rom, but lg flash tool tells me it's the wrong device (now thinks it's a D802).
I've been trying to get into TWRP on scrosler and samsunggalaxystig's advice, first by repeatedly trying an adb reboot recovery, then by writing a batch script to do it repeatedly in order to catch it before it reboots.
Problem is, I don't know if I had already had ADB drivers installed on this computer for the G2 (had rooted while at work), and despite installing them more than once, I don't think the device actually has enough time to be recognized as I still have an unrecognized "g2" in device manager while TWRP is wiping.
Any ideas? Is there any way I can force the install of the ADB driver without having it connected for more than 20 seconds? Spitballing... would it be possible to actually flash a D802 image so I could then root, change the build.prop to D800, and then flash the D800 image?
Totally at a loss at this point.
did you solve your problem? i have a similar problem and i just bricked an s3. this g2 is brand new and now it's bricked too! if you have found a solution please respond... :crying:

Why did flashing a rom leads you to that error? Sorry but not familiar with your roms but is this rom really for your LG G2 model?

twrp corrupted my cache partition and the phone could not boot. i tried to flash cwm while in twrp and i guess i messed up recovery and/or boot partitions. al i could get was fastboot. i flashed a boot.img i got from somewhere in here. now it says security error and it does not boot. it does not enter into fasboot. i can enter into recovery mode but it is the stock lg recovery and if i choose "delete all data", which is the only option, it gives an error and restarts.
if i try to flash stock firmware as described in this post it stops at 49%.

Can someone help me I successful in installing twrp though autorec apk and the same for rooting my g2. I flashed cm with nightlies and noticed that twrp had a update. I downloaded the zip and try flashing it like flash a recovery in flashify but that din't work and readed that zip flashing though twrp didn't work but renumber this video and though it would update my recovery to 2.7.1 but it was successful in doing so but when I got to recovery it was 2.7.0. That not the problem form there I tried to boot into my system. Then it turn off though that I passed power off instead but when turn my g2 back on I found that I had a security error show up then turn back off. So can someone help show me a tutorial on unbick or a way to remove error. Also I have the d800 and i have some idea without going though unbicking a hard factory rest or flasing twrp form there site in fastboot. Finally that lg mobile support tool say that im up to date. I think doing the autorec twrp recovery locked as my phones recovery like trying to flash a rom with a locked bootloader.
Ok guys i trying to help cause it happen to me too,sorry for my english too slow but i try,when you try go twrp with volume up+power buttom it still show security errow,that ok your device not hardbrick yet,when you try volume down+power buttom it show hard reset it does mean it clear all rom,picture in internal but it go to twrp again,and them just flash another rom in your device and it done,have great day piece
I had the same problem on my G2 was using twrp to flash cyanogenmod not sure what i did and phone rebooted to show security error message. I entered recovery mode (power and volume down release when logo pops up and press power and volume down again hold for a second then tap both buttons a few times) pulled up the option to factory reset so i did and it booted me into twrp and allowed me to flash cyanogenmod correctly this time and the phone started back up with no problems. hope this can help someone else as well.
Anybody know the solution?
I also have the security error boot loop after flashing KK baseband files... I tried to enter recovery mode by holding vol down & power button but it wont work...
it does work when i enter download mode (vol up + power button), but i don't want to have to download the stock LG ROM..
anybody know how to by pass the security error boot loop to allow me to reflash?

if you still bricked. try this
get your tools from here: http://forum.xda-developers.com/showthread.php?t=2432476
keep reading or follow above thread. both will work.
best of luck.
After all the drivers installed correctly
make sure your phone is connected to the
com41 port change it if it already not ( Under device manager > Go to Ports (COM & LPT). You should see LGE AndroidNet etc... Right click it and go to Properties > Port Settings > Advanced > Change COM Port Number to COM41 > OK > OK > Close Device Manager )
run flash tool
1. choose type CDMA
2. chose PhoneMode: DIAG
leave rest as it is.
3. choose your kdz file.
then go to download mode
1. power off
2. press and hold vol + key and plug usb cable
3. done )
We have go 2 flashing modes.
1. Normal Flash is for flash with keeping data
2. CSE flash is totally new start preffered.
hope this helps.
thanks but it was a long time ago and I further messed up things, ended up sending it for warranty. they have replaced the device.
me too messed up my cell 1st i was on cloudy g2 v2.1 installed cm11 nightlies but the camera was not so good so then installed cloudy g2 v2.1 n since then i was having problem regarding sound during call and also some hard noise like siren starts randomly, i searched alot but didnt got any solution. wiped all many times (including internal storage ). but no luck then i thought i might be baseband error so i just downloaded auto recovery n flashed it n then stuck into security error but thank GOD i had custom rom in my sd card that time i flashed it back but still em having the sound error.

Hey guys, I was in the same boat for a little but was able to fix it by downloading the 801C firmware and flashing it. The firmware file should be a KDZ extension and you should also download LG Flash Tool 2014. Turn the phone on by holding the Power button and Volum up while it is plugged into your computer(It has to be plugged into a computer with LG phone drivers or it won't work).
Follow this tutorial and you will be set.
http://www.droidviews.com/how-to-restore-lg-g2-to-stock-firmware/
Start at step 17 on Method 1 and you should be golden.
Hope this helps guys!

hi guys,
i flashed recovery using the manual method from this thread http://forum.xda-developers.com/showthread.php?t=2468858.
I wasn't able to use the last command
Code:
rm /sdcard/g2_security
I thought it didn't work , i also updated the my phone software.
When my phone restarted it went to cwm and now its stuck there.
Now when I try to boot I can either get in CWM or some Korean Recovery Menu with three option (i tried all nothing happend) or just stuck in boot loop!
I can't get in download mode by pressing vol up and plugging usb cable (tried all possible methods)
I will be glad if someone can help me out.
Thanks in advance
That's an unexpected situation to say the least.
So in short: installation of recovery worked, but you lost access to your ROM.
Correct?
Now, if you had a flashable ROM on your sd card you would be sorted, no?
I would say, get any compatible ROM, put them on a micro sd card and plug them into your phone. Flash through cwm...
Am I misunderstanding?
Otherwise there is always the fully back to stock option:

Good to know i wasn't the only one
Im just able to start researching now, i'll update if i find anything, but i assume there's some kind of command that can be given via adb to disable the fastboot and allow the phone os to resume functioning, as my logic indicates since the restore worked for you, your phone is now simply at a point with no attempted update. i did the same process of clicking reboot, twrp looping, restored a backup and twrp still looping
EDIT: Pretty sure it's going to be a flag in a flat file. Combing over my init.rc file now, and i found a strange file called smpl_boot with a single 0 in it, not sure what it does

Can you enter Download Mode? (Holding volume down when G2 is turned off and plug the USB)
I also experienced this when restore using TWRP. But fortunately I can flash back to stock.

Hi, sorry for my english , I'm french
I wanted to flash a custom rom on my LG G2 D802 .
I wanted the Paranoid Android (PA +) with 4.3 JellyBean .
So I made the
Backup
Wipe data / factory reset
Wipe cache partition
Wipe dalvik Cache
After I
Choose zip ( custom ROM ) from sd card
Then I
Reboot System Now
And turn on my laptop, I get an error message saying
[640 ] started Fastboot Mode
[ 690] udc start ()
I realized I had to flash AOSP kernel before changing to a ROM paranoid . But my kernel is blocked and so I have to go back to the stock ROM
When I did this tutorial using lg tools , flashing stops at 49% with an error message .
I also saw that I could access the recovery mod by following this link http://forum.xda-developers.com/show....php?t=2565904(but I saw that I could not otherwise reboot my phone after it was bricking ) and therefore flash my stock Rom which I had made the backup . But I do not know if the ROM has been saved and if it remained in my files after the Wipes.
If it is not there, is that in buying a micro USB ====> HUSB adapter, I could install a stock ROM from a USB key ? Or is there a way I can put files from my computer to my laptop which has no port micro sd?
And is what I could with my kernel "blocked " ?
Thank you very much
Same problem here too. Can't get a recovery installed no matter what i do
Does anyone have a solution yet?? Same thing has happened to me.
If you can't go into download mode but get fastboot mode instead first repair download mode using http://forum.xda-developers.com/showthread.php?t=2477595 and than flash back to stock 4.2.2 using http://forum.xda-developers.com/showthread.php?t=2432476
My G2 can not go into download mode and recover mode, and my computer can not recognise it so I can not put anything to it.
fast boot
udc error.

EXPLAIN IN SIMPLE WAY STEP BY STEP.
Thank you
Had this exact error too, fortunately flashing furnace kernel fixed it.
Tahir, I had to try several times until i succeed to boot to my recovery mode, try several times.
was having this issue. but i figured out my problem. the rom i was installing was a note3 rom. hahahaha. thats what happens when u have too many phones. and files in your computer. anyways.
i ddnt have to revert back to stock. i was able to reboot to twrp via hold power button and volume down buttons, when lg pops up, let go and press and hold both buttons again. when white screen with words comes up, press power then power then power. then ur back to twrp, at least mine did. and restored my recent back up.

Try booting to recovery after you charge your phone for at least one hour and while it's NOT CONNECTED to the computer
If that's doesn't help try using ADB
I'm sorry if there is a post for this already, I have been using this website for a while and until now never had to post because all my questions were answered. This time I am not able to find an answer or even a thread with the same circumstances as mine. I rooted and installed a custom rom but didn't like it. I tried going back to stock but accidentally wiped the phone so the backups and the roms were gone. I had TWRP installed but it wouldn't allow me to sideload via adb and when I tried to enter download mode, it would enter it but go to a screen that just said firmware update and stayed stuck on there. So I went out and bought a OTG usb cable to read the rom off a flash drive and I installed it but now instead of going to recovery it goes to a black screen that just says fastboot mode udc start. Download mode still does the same firmware update screen. Any help would be appreciated, thank you.

Ive tried lg tools method to flash a tot firmware but even having all drivers it doesnt happend, i tried fastboot method with command prompt to flash recovery twrp again and no luck either, i ran out of options here but there is gotta be a solution for this PLEASE HEEELP!

I just saw this. I have done the same thing. But I have been able to recover with TOT file. The trick to enter download mode is to hold the volume up button when you power on the phone. If you can get the phone to stay off, then hold volume up, while holding vol up plug in your data cable. You should get DL mode. If you do this while the LG Flash Tool is open, then go to control panel and find the COM port for the LG phone, open properties and advanced, change the COM port to COM41. Once that is done, also once the flash tool files are loaded and the COM41 box says ready, unplug your phone then replug your phone. You may have to also hold volume down here, I can't remember. But the first time is to let the drivers configure. The second time lets the flash tool see the COM port and it should start flashing. It will get around 80% and reboot. The flash is done and the tool will eventually report an error.
I installed the KK baseband as instructed, even also came from the stock ZVC update, rooted via IORoot25. It's a shame as I've heard great things about this ROM.
Hope that helps.

So here's what happened i was flashing the LLAMA Sweet Kernel for my D802 from RenderKernel (KK Bootsack loki signed, KK Bootloader) then i got stuck on LG Logo at first i thought it was fine but it hasn't move for like 30 mins. Then i tried to reboot and enter recovery mode. I can't enter recovery mode i tried it several times turned off first then Volume Down + Power button its not working anymore. But i can access DOWNLOAD MODE which is good i think.
Can someone please help me sort this thing out i just need to have TWRP recovery and i can handle the rest. How could i flash it using download mode. Thank you guys
LG G2 D802
16GB Version
Euphoria ROM
LLAMA Sweet Kernel
Try installing the stock LG Mobile Support Tool and USB drivers.
Open the support tool program, connect the phone in download mode, click on "Options" in the top right-hand corner, select upgrade recovery, and, hopefully, the program will download and install the correct firmware for your phone.

Will this one completely delete everything? Or change the current ROM i've been using // Will this one also delete media files photos/music etc?
Is there any way that i can just flash TWRP on download mode so that i will just flash bootloader/bootstack or kernel thats causing this bootloop/brick.
Thanks
Yes, it will wipe everything.

So There's no other way to save my media files. i mean there's no other way to flash any recovery to my phone even though i can access download mode? Is that it sir?
have you tried re flashing twrp?
How can i re-flash it? ROM not loading stuck on Boot Logo, can't go to recovery. Only download mode working i already installed drivers and its been detected. I just dont know if there's a way to flash twrp on download mode.
I read some posts where it will delete data, others say it won't. I would just assume that flashing stock would return to stock and delete data.
Not sure how to flash twrp from download mode.
Problem solved! i was installing the wrong version of twrp this is the correct version: https://eu.dl.twrp.me/j5xnlte/
I'm using SM-J510H
So I installed samsung drivers.
I even installed ADB and it's drivers (now i have samsung android in the device manager)
I downloaded TWRP for j53gxx:
https://eu.dl.twrp.me/j53gxx/
The .tar for odin (twrp-3.4.0-0-j53gxx.img.tar)
I did the OEM unlock and debugging thing I even got the notification that the computer was trying to access blah blah I did allow always.
Put the phone in download mode (Down + Home + Power)
Press up to enter download mode.
Connect the phone.
Untick reboot in odin.
Use the ap to select the correct file
Start success!
I try to reload into recovery tried so many different ways even the adb command to reboot into recovery. All I get is a little thing on the top left saying warranty bit recovery and then the screen is black.
It doesn't load into the default recovery it just stays black. I need to take the battery to rest...
I tried with adb but when i force it to load up into download mode (adb reboot bootloader)
adb doesn't recognize the phone anymore
I've now downloaded the android ask maybe that will solve things lol but does anyone have any advice please?
Should I consider installing a different recovery? like maybe CWM?
It has a costume rom on i guess it says "Hebrew by daniel mouyal for bt" in the about tab in the settings...
I tried using ADB to install but when it's in download mod it can't find the phone so when i enter the install command:"fastboot flash recovery twrp-2.8.x.x-xxx.img" it says: "waiting for device"
Well I've been installing the wrong version of twrp lol sry!
So just in case someone else hits the same problem it's not the twrp i posted before but this one:
https://eu.dl.twrp.me/j5xnlte/
When recovery is finished flashing in Odin, remove your battery to turn the device off.
Then put the battery back in and press vol+ and power button and home button at the same time.
Your device should then boot into twrp.
If you reboot before doing this the android operating system will ovewrite twrp with stock recovery and you will have to start the process again
Also you used the wrong twrp. J53gxx is 2015 model j500h and j5xnlte is j510fn not j510h. You must be careful or else you may seriously damage your device.
Use this twrp here for your device j510h

Thank you for the response!
I managed to figure out the issue it was the wrong twrp version.. I can't update the title though
That's no problem.
What I would suggest though is to post how you fixed your issue in case anyone has problems in the future they can be referred to your thread here
