i have a VS980, rooted and with TWRP
i wanted to update TWRP so i can install a kitkat rom, when i did this, some error happen, and now my phone wont boot and cant get into recovery mode, when i try to get into recovery, a black screen that says flashboot appears
i dont know what to do, please some help

Hmm did the ROM install and once you reboot does the fastboot show? Have you tried using the hardware key method and getting into recovery?

I had the same issue recently (which got me to start posting on here after using this forum for help). If you can get into your ROM regardless of the lack of recovery, that would be a huge plus. The VS980 is not friendly with GooManager and TWRP Manager. However, it's friendly with the Flashify app. Give it a try if you can boot into your ROM.

i was updating TWRP to the 2.7, wasnt changing the ROM in that moment, apparently i did something wrong, and now if i try to get to recovery (with the key combination) it stays on fastboot
if i just turn it on, it stays on bootloop
if i go into download mode, my pc kind of recognizes it, but doesnt let me puso a recovery

hmm ya if recovery is pooched and you cannot use adb to install another one... i think your only option is to use flashtool and install kdz again...

I'm assuming you already finished the KDZ process. If you haven't and can boot into your ROM, you can ressurect TWRP via adb or the flashify app. I went through the same situation as you and could boot into my ROM.

How to boot into TWRP recovery mode from Phone OFF state

I cannot figure out how to boot into recovery from phone off state. If I go to ROM Toolbox pro and reboot that way into recovery, then it works fine, but NOT from phone off state. Thanks.
Press/hold vol down + press/hold power will get you to the bootloader, then select recovery from there.

Did you "fastboot flash recovery recovery.img" or "fastboot boot recovery.img"?
Got, it. Reinstalling recovery from Goomanager, worked. For whatever reason, my recovery was repalced or gone.

Hey the same thing is happening to me as I am using my Nexus 5. Can you please show me how to do what you did to find this. I cannot boot into recovery. When I try installing TWRP from GooManager it just says it will download but it never does and then after a while the app shuts down. I tried flashing clockwork mod recovery from Rom Manager and it downloads all the way and than says that a problem occured. Can somebody please help me with my situation. When I press the power button and the volume down button and it brings me to the bootloader and i navigate to recovery, it just brings an android guy with a red triangle. please help me. I just want a custom recovery. I don't care what it is. Either TWRP or clockwork mod.

Hello forum peoples. Recently I have tried to flashthe paranoid android firmware using flasherfy. I have twrp installed but idk if I was supposed to do with it. My phone is now in a boot loop because of my attempted flash. Please help me fix this. I am able to boot into both firmware update mode and factory reset mode. For the factory reset mode I am able to boot into the reset mode but as soon as I try to wipe it just reboots again. I have tried to use the lg firmware update tool using com5 and com41 and using both they stop at 49% and the phone just disconnects from the program/computer. Help Please! !
EDIT: I have an lg g2

For stock recovery, yes you'll see that screen. On that screen all you have to do is press power button and then press volume up (just one quick press) and it will take you into recovery menu.

You have a LG G2, so please. Ask in you device respective forum. LG G2 got its own forum too you know.

[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?

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!

LG G2 F320L stuck in Boot Loop not going in download mode

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:

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.
