[Q] Flash stock with security error

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%.

HELP!!!!!!!!!!!!!!!!!!!!!
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?

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.

Start at step 17 on Method 1 and you should be golden.
Hope this helps guys!

Stuck in Clockworkmod Recovery

Hi, I've tried to install Android 4.1.2 on my LG E610 L5. The rom I chose was 20d + root + cwm. It worked just fine, but I've accidentally let it update itself, not knowing you should do that on rooted devices. Not whenever I turn on the phone it shows me cwm recovery menu. Rebooting doesn't work and I can't get into stock recovery mode. I've tried hard reset, clearing cash and data, flashing another rom, nothing works. Is there anything I can do other than giving it to service and paying for getting it fixed? Cwm version is 6.0.2.8, I can link to specific download link if that made a difference.

I'd try that, but KDZ won't detect my phone. I can't boot up the system and there's no download mode in cwm. Is there any way to flash stock recovery using cwm?
I basically need anything that would make my phone show up and be detected by kdz. May be rom or different recovery.

okay first of all you need to go to google and find the right driver for your phone
next take the battery out of your phone and then plug it in to your computer while holding the volume up buttons
next go to your computers drivers via ( Start->right click on computer and go to properties->then go to hardware then drivers-> look for something called modem and if your phone is under it then disable it)
next open the KDZ updtaer
install that mx thing
then open KDZ updater set it to 3GQCT and EMERGENCY
then select your KDZ updater
launch update
it may say errors but let it finish.

Phone's display shows LG logo. Left for an hour, nothing happened. If I try to do KDZ update, it says "PHONE WAS NOT FOUND! "

How can I get into fastboot mode? None of the "press volume button and power for 30 seconds" methods work. @edit From what I've read, LG L5 doesn't have fastboot. Damn it.

Did you tried to remove the battery and enter emergency mode ?

OK, so that's really interesting. I've connected the phone to the PC, uninstalled drivers and let Windows Update install it's own. Doing so, instead of being stuck on LG logo, I was now in fastboot mode, despite being said LG L5 doesn't have fastboot. Anyways, I've flashed stock recovery.img I've found here: http://forum.xda-developers.com/showpost.php?p=37363473&postcount=1023. Using Vol- and power button I put it in download mode and managed to install clean soft from official LG website with KDZ. I'm not really sure how it worked, but it did.

I don't know what i did but after a week i tried to boot it and it booted up so its working now

Ok every one iv posted a simulare problem a month ago, when you use kdz, and it flashes stock, if after the flashing it stays in a boot loop all you need to do is leave the phone on boot with the lg logo for 10 mins.
After that unplug your phone, put the battery back in.
Now all you need to do is a factory reset, press and hold Vol down + menu, press power after the phone vibritas let go of the power button and keep holdind Vol down + menu for 10 seconds.
The phone will factory reset and boot up normaly.
This works on all versions of L3/L5/L7

but when i do so after the kdz update the phone boots automatically in cwm, so i cant let the phone do what it does during the logo display for 10 minutes. I have an l7

I had no idea what I was doing back then, so I haven't tried a simple solution, but you can try flashing a ROM. The fact you boot straight into recovery is a sign of no/corrupt system, so flashing a different one may fix it. Pick one from Original Development and follow the instructions.

[Q] stuck on boot, no rom installed and can´t enter recovery

I´m stuck on boot and I don´t know why but I can´t enter in recovery mode with the volume down and power button combination. I was in TWRP recovery and had a failed rom flash, but I accidently touched the reboot button and now I´m stuck on the LG logo . No button combination is working for me :/ sorry for my english and pls help me what should I do?

A failed ROM flash shouldn't affect your /recovery partition. Unless it included a Recovery of course. What ROM did you flash? Your Kernel is probably stuck trying to load a non-existent user space (no ROM/bad system partition).
Make sure your device is fully powered off by holding the POWER button for 30 seconds. This will make sure your device is OFF.
I know you've tried one of these methods, but try both of these methods to access recovery JUST IN CASE..
Method 1 (JB Bootloader).
Turn device OFF. Press and HOLD Power + Volume Down. When the LG Logo appears let go of both buttons and again press and HOLD Power + Volume DOWN.
Method 2 (KK Bootloader).
Turn device OFF. Press and HOLD Power + Volume Down. When the LG Logo appears let go of both buttons and HOLD Volume UP + Volume DOWN.
Can you access Download Mode?
Turn phone OFF. Hold Volume UP and plug phone into PC via USB.

thank you for the fast reply, I tried it but I can´t access recovery mode.
But download mode is working, what would be the next step?

I'm curious though.. what ROM did you try to flash?

I´m downloading right now thanks for your help.
But there are a few questions I would like to ask what does the download mode look like? I know it´s kind of a silly question but it shows
"firmware update
do not unplug the USB connection until the process is complete
0%
USER B84
ROOTED"
on my device is that normal? and my other question is am I going to lose all my data after flashing that kdz?
edit: I flashed a stock lp rom and it showed SystemUI error after boot so I couldn´t use it at all, at this point the button combinations for the recovery mode weren´t working,too but after waiting some time the SystemUI error was gone and I could use my phone for a few seconds so I kind of managed it to enter into recovery mode an tried to flash the latest darkobas rom but that failed...

Yes, that's the normal Download Mode screen.
B84 is your Battery Percentage.
The ROOTED text is just telling you that your phone has been Rooted.
When flashing your KDZ you have 2 options.. CSE Flash and Normal Flash.
CSE Flash will wipe all partitions. Choose this if you want to start fresh.
Normal Flash will wipe some partitions and keep your data.
Don't change any of the other options!
I recommend you do a CSE Flash too be honest. I haven't messed with Lollipop enough and have never done a Normal Flash over it.

for some reason it is failing at 2%

Radon7 said:

Click to expand...
Click to collapse
Is that using Normal Flash?
Have you tried CSE Flash?
What model variant of the G2 do you have?
Lollipop changes your partition scheme a little so trying to flash a KK KDZ over a Lollipop partition scheme will cause errors, unless you do a CSE Flash. This is also why once you flash LP you can't just flash a KK ROM afterwards. First you need to revert your partition scheme back to what KK needs.
So with all that said.. do a CSE Flash. If you're rooting and flashing data using custom recovery you should always have a back up of all your data/media on your PC anyway .

it´s the same using both methods normal and cse :/
I have the d802 version, and I´m trying to flash a lollipop kdz, should I try it with a kitkat one?
I also found this thread but I don´t know if it´s useful because I need working recovery for it to work I think

Yes try a KK KDZ. If the KK KDZ continues to fail, try the TOT Method (the TOT method is under the KDZ method).
Yes that's the post I made a while ago.. which I was going to possibly link you to if you had a D802 .. but I forgot you can't seem to access Recovery at all.

BOOTLOOP/Brick LG G2 (D802)

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

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.

LG G2 Hard Bricked

So I wiped the system partition on my LG G2/D800 (mostly out of stupidity) and now I'm stuck in the boot loop.
Symptoms are following:
1. Stuck in the boot loop
2. Will not go into download or recovery mode
3. When turning on the LG logo appears and disappears repeatedly
4. Device is not detected when plugged into the USB
5. Factory reset using VolDown+Power doesn't do anything
I've tried most of the ideas I've been able to find on the forum, but it looks like I'm stuck mostly because I cannot enter download mode and the phone is not detected in any way when plugged into the USB (no many partitions or anything).
Will be grateful for any ideas how to get out of it?

so vol up and then plug usb, does not take you to download mode?
if not try using srk tools.. if that doesnt work i think you need to short circuit your motherboard.

Indeed I cannot enter download mode with vol up then plug usb.
Good news is that I was able to enter qhsusb mode by short circuiting the moterboard. I used srktools to unbrick in qhsusb mode, however it didn't work. The linked guide recommends to flash only laf.img, aboot.img and boot.img. I don't really understand how flashing more can hurt. I also don't completely understand why flashing these should help. After all, I messed only with the system partition. I'll try to follow the guide more closely, but I'm thinking that a better idea would be to flash system partition in a qhsusb mode. I just need to figure out where to get system.img from.

So now I can consistently get into ghsusb mode by short curcuiting the motherboard, and I can flash img files with dd. I flashed every partition from the stock FW which was on my phone. Now when hold vol up and plug in usb, I'm ending up in a stock recovery. However, I still cannot enter download mode and the phone still suffers from boot loop if I choose to reboot the phone.
