Hello !
My LG is Running 4.1.2
I Root my Phone ! But 95% my phone is restart and i see error on my screen is "Security Error"
I can't go D/W mode when press Volume + & - and USB Push in !
i need help ! Thanks
Please give more details for others to help, such as how did you "try to root", what do you mean by 95% (95% of time, I guess?). There is only "SW Upgrade Mode", no "D/W mode" as you mention.

Hello, i need your help !
I have a phone LG L9, bootloader is UNLOCKED. I installed soft CM 11 and all was well. One time phone rebooted and stuck on LG Logo. So using 'S/W Upgrade' im installed new soft by LG Mobile Update/Tools (emergency recovery software). Unfortunately the problem is still, all times stuck on LG Logo.
You can write me some advice what to do now and is there a chance to fix it ?
Bootloader: unlocked
S/W Upgrade: working
Thanks you, sorry for bad english.

try factory reset
pull battery out
press and hold volume up +home+power button (try volume dwn if vol up didn't work)
release power button when phone vibrate
same issue after chainfire
I am also stuck at LG logo with only option working 'Software Updating mode' but offline flash is not detecting phone even though
LGE USB Modem , LGE Usb Composite ,LG Com port are getting installed correctly.
Hard reset also not working.

After installing Paranoid Android 4.6 Beta 5 on my LG G2 , I made a false manipulation in TWRP .
When my start as the LG logo appears with "Security error" display and then turns itself off . I do not have access either to recovery or to download mode.

Try to press and keep pressed vol up + power button.This need to get you to Download mode,then just flash stock.
P.S.-Let me guess,Bump!?
Go to the unbrick thread for a guide, you may have screwed up your partitons.
Hi everyone, i'm new in the forum, my name is Edoardo and I'm from Italy.
Yesterday i tried to unbrick my LG P760, and I did it, getting in the Security Error screen.
So i tried to flash the default firmware with KDZ (V20C),i set emergency, boot the SW Upgrade mode on my phone and then clicked on launch update.
my phone stays on for a while, and when kdz says unpacking kdz, after about a minute the phone power off.
i tried with lg mobile support tool, at 15% same problem.
for the unbrick i used this on Win7: http://forum.xda-developers.com/showthread.php?t=2411265_
and it worked.
what should i do now? the phone was rooted, and with CWM recovery. the night before the total brick (if it matters) my contact numbers disappeared, so i shutdown the phone, and then power on, with the result of a black screen with this text:
-----------------------------------
Secure boot unsuccessful!

Sorry for my english.
Hello everyone,
I was flashing my phone using "LG Flash Tool 2014", but due to power failure the process stopped. Now my phone is stuck at "Download Mode" I can't do anything. Every time I power on my phone all I see is a banner saying "Download Mode". I tried to use "LG Flash Tool 2014" to flash stock .kdz ROM file, but it does not work. I get to 10% and it stays stuck at that... I tried to use different computers, but the same thing occurred. I tried accessing Recovery mode, but no luck there either. My phone model is LG Optimus LTE2 - "F160s". Please help me. Is it possible to fix my phone? I think it's badly bricked or maybe dead. Not sure, any ideas? Are there any ways I can flash my phone again using Windows or Linux?
My issue is that I bought a LG phone Optimus LTE2 f160k and I root it. The blunder i made that I removed some system applications.
When I restart phone, it didn't. I tried to enter in recovery mode(power+volume up+home) and made hard reset but nothing happened, and download mode(power+volume down+home) but the mobile not connected in download mode, instead it just restarting every time and showing security error whenever I connect my phone to PC.
Now the current situation is that my phone is powering up by pressing power button. and LG logo then security error .
The problem is that where should i start now? how can it unbrick my phone?. any tools?
Please help me in this as I am very worry about it.
