How do you use emergency mode in kdz flasher? What is the kdz flasher? And, how do you flash firmware with fastboot, flash recovery restore v20d from recovery backup?
The phone is not being very cooperative with me... I can get to the emergency screen but can't seem to do anything besides that. I've taken a picture of what the error screen but I'm not familure with this phone....
Please help... here is what the screen says
[Blue Error Handler V1.2] Arm11 Crash!!

all the answers are there

IT'S A KERNEL ERROR
1. Have the necessary software.
- Phone Drivers
- KDZ_FW
- The Room you want to install, in my case I served in the final Android 2.1, I suppose due to the use Android 2.2 I had made a partition so I'm not allowed to return to that version of Android.
2. When we light up the phone and leave us this error screen, press the power key + the Volume Down key to set the phone into download mode or (Download Mode).
3. Disable USB LG Driver Model, this will change depending on the operating system we have in the case of windows will be in Manage> Device Manager> Modems> LG USB Drive Model -> Right Click "Disable "
4. Open KDZ_FW select type 3GQCT, Phone Mode: DIAG, consider the room to install (File *. kdz).

Cannot flash any rom on my phone
Hey there, sorry if im spamming or doing any newbie thing, i've always try to stop that.
Recently i've try to get a rom on my phone but I've just got the kernel panic (blue error handler arm11 is crashed!!) I've had that before and solved it with no problems, but this time my computers or my brother's computer do not recognize the phone, not even after disabling the modem, and just when trying to flash a KDZ, this is what i get
[R&D Test Tools Log File]
02:56:37 : Launching SW update
02:56:37 : Unpacking KDZ
02:56:47 : KDZ file extraced
02:56:53 : Files were extracted.
02:56:53 : LGMobileDL Load.
02:56:53 : Port = -1
02:56:53 : Connecting to phone
02:56:54 : PHONE WAS NOT FOUND!
02:56:56 : ===FINISHED===
I don't know what can I do, tried with 2 computers, CS_emergency mode, 3 diferents rom, disabling the modem, but nothing! Even not in download mode.... Any suggestion?
As I said b4, sorry 4 spamming and 4 my english

if this happens (mine was bricked cant turn on no download mode no nothing) just send to lg get them to help you upgrade to 2.1 then try again

Is that the only thing left i could do? No way to try to fix it? I could send to the provider, but I don't know if there's a LG provider around, I may send it to "Movistar" (where i bought it)

Whats just curious, is that my pc recognizes the phone, but the KDZ updater cannot! :/

like they say.
lg modem off in device manager.
switch-mode phone to downloding.
and try again. if youre phone die at 215, try with another soft

Or, delete ALL LG drivers, then restart ur PC, install them again, connect ur phone and flash in cs emergency... if doesn't, try another KDZ, or look for an out.kdz which could help, I've got about 7 arm crashed (kernel crash) and solved them that ways I just mentioned
Sent from my LG GT540 using XDA App

one trick about drivers is that you can try to connect it to the port you've never used before on your pc to connect your phone. It should then automaticly search and install drivers to recognize your phone

To all..
To fix this when I got this error you need to reflash a fastboot 2.1 and then go into fast boot and type the commands fastboot-w to wipe it then reboot into download mode and flash the normal stock rom

Same here :/ cant fix sending back to LG

[Q] Lg G2 Brick Security Error Bootloop No recovery, No download, PC don't recognize

Hello everyone !
I have big troubles with my Lg g2 d802.
Yesterday i want to intall crdroid 5.0 on my Lg g2 on Official 4.4.2, so i've:
Root my phone
Install CWM Manager
Set CWM Recovery
Reboot in recovery
Use ADB Mode
Use ADB on my PC to send crDroid zip by sideload
During sideload, after full download, there was an error assert failed. So installation failed, and i've decided to reboot my phone.
Problem is here, my phone boot, display LG Logo and after 5 seconds, Lg Logo with "security error" message, then stop alone and reboot again, and again.
I have tried following procedures :
Power off completely my phone and then Volume down+PWR to enter in recovery : FAIL
Volume Up and then put USB cable to enter download mode : FAIL
Connect with USB on Ubuntu to try to reset .img files : FAIL (Phone invisible on my pc, even not recognize)
So i cannot go to Recovery Mode, Download Mode and my phone isn't recognize on PC.
I don't have any other ideas and i am here to asking help .
Thxs for reading, and i pray for a miracle !

Even I have suffered with same problem
Follow this thread I think you must have seen this thread it is the best solution till date from recovering the problem you are in right now.
http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
But you have to mess up with your phone motherboard but its really very easy. Just follow it. I have recovered mine from this.

Ok i'll Try it ! Thx you !

I have tried your link and its working. My phone is alive ! Thx you .
I have a last problem. My phone has 2 black lines on the screen from top to bottom. This appear after i had flash new .img files. Does anyone have an idea about what i need to do to remove these ?
Thx you again

Impossible to install/boot on custom recovery

Hello,
I wanted to install the last Cyanogen snapshot for my LG G2 but I am not able to boot on custom recovery...
I tried many ways to install it, using for example:
- flashify
- MK802 CWM
- Mobo Daemon
- even Terminal
My G2 is an international version
I have now Lollipop 5.0.2 (build LX22G)
Software V30b-EUR-XX
I succeeded in rooting my phone, hopefully. But now when I want to boot on the custom recovery, I have this screen:
Erase all user data & restore default settings ?
No (Exit)
Yes
Click to expand...
Click to collapse
If I continue, I have the following issue:
Critical Error!
DemiGod Crash Handler : Critical Error!
Press key to choose Dload Mode or Reboot
[...]
Board Info
Rev : 1.1 speed, pvs : 1,1 serial : 038d0d1fa3d0cfbc

What can I do?
Thanks in advance for your help.
I found this topic, I don't know if it will help me:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076

i had same issue. I was able to get out if by turning off phone, pressing up button and inserting USB cable. That made phone boot up in download mode. Then I used LG flash utitlity to flash the stock kitkat rom.

You mean I have to flash the stock kitkat rom (sort of downgrade) and then flash anything I want?

No other feedback?

I finally found the solution!!!

I was on LG stock ROM, not CM. But I found the issue
(En effet, "unable" sonne beaucoup mieux, je n'y avais pas pensé, même si "impossible" ça passe je pense ^^)

It is because I have an strong kernal?
Is there any possible solution?
I was dying to install 5.1 but I stucked upon this...Please XDA Team I Am expecting a quick solution....
If it is due to kernal version is there any possible way to install an old stable kernal? Is it possible to install custom ROM?please give me a solution

Your bootloader is locked. No possibility of flashing TWRP or any other recovery, kernel or ROM other than what's already on your phone...
The only thing you can do is root which you have already done. Next step is debloat and learn to live with your phone
