I think this should work for people who cannot get into recovery mode, computer cannot detect the phone or have security error message.
How I bricked my LG-E450b
I thought rooting for this phone was like my Samsung phone, so I installed Kingo-oneClick-root, got root and deleted all of the bloatware.
Little did I know that I could actually brick my phone by deleting some LG apps (Stupid LG).
Symptoms of my bricked phone
Secruity error message
Phone would not be able to go into recovery mode (Volume down + Camera button + Power button). It would restart after 3 seconds or so after the android loading gif.
Phone would not be detected by the computer
LG support tool could not detect phone (since computer cannot detect phone)
LG support tool would stop at 4% when trying "upgrade recovery"
I was basically stuck and thought my phone was hard bricked. So I started playing with the phone hoping for some magic thing to happen and I got lucky!
How I fixed my issues
Remove case and connect the phone into the computer with standard usb cable
Power into recovery mode (Volume down + Camera button + Power button)
Just before the phone displays the security error, remove the battery (phone still connected to computer).
Put battery back in and turn on the phone normally (no recovery mode)
If it worked then there should be a white message on the bottom left of the phone saying "Download mode: "
Optional: If the computer shows that the device attached has an error then you are in the right direction! Go into device manager (run devmgmt.msc) and right-click on the device that is not detected and uninstall
Optional: Hold power button until the device shuts down and repeat from step 2, the next time you get into download mode the computer will detect your device
Open the LG Support Tool (almost done) (attached in this other forum post)
The phone should get detected by by the LG support tool. Try to update the firmware. If the Support tool says that you already have the latest firmware then go in Options->Upgrade Recovery and put the model number or IMEI/ESN/MEID of the phone and click ok; the recovery process will start and your phone should work
Note: If the phone is not detected by the LG Support tool, then it will not work (it will stop at 4% when doing the upgrade recovery). The phone has to be detected for this to work.
Conclusion
These are things that worked for me, but I am no expert. This is not a full proof guide and I am only posting the steps that made the phone work. It might possibly be that you don't have to do all the steps described above to get into download mode, i.e you would just have to remove the battery at the right time to activate the download mode.
I am posting this describing the exact steps I took, so this can hopefully work for someone else.
Good luck!
TL,DR : Remove battery just before the security error message and reboot phone to get into download mode.

So I've finally decided to root my S3 and run CM9, as from what I hear it's very stable now. Only problem is, I seem to have fallen at the first hurdle!
I've been following the SGS3 full update guide on the cyanogenmod wiki.
I powered off the handset, booted into download mode, opened zadig.exe in the drivers folder of the heimdall suite, selected options>list all devices, selected "Gadget Serial", clicked "Replace Driver". A message popped up saying it was successful. The guide simply says to power off the device and reboot into download mode again. However, after this I could not power off the device. The power button wasn't working and I got no response from pressing any of the buttons on the device. Eventually I decided to open it up and remove the battery and then try to boot into download mode again.
Now, it doesn't boot into download mode at all. Every time I hold the volume down and home buttons, I then connect the micro USB and nothing happens at all - it just begins charging. The phone can boot normally and appears to be functional apart from this, but this is stopping me from being able to root. Anyone know what could be the problem?
Thanks!!
Just tried factory reset and still no dice.
Has anyone come up against this before?
And, just to be sure, you are holding down the power button when you press volume down & home on a powered off GS III, right? Since you say you're rooted, you can boot into download mode from the phone itself:
Grab https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
Run su reboot download
Yup, I was. Seems that after enabling USB debugging after factory reset, the problem has resolved itself. Thanks for your help anyway
Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open
Sent from my LG-P769 using XDA Premium 4 mobile app
I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

help lg p768 encrypting error problem
can someone help me please.
i have the same problem from the starter of this thread..

i dont know what to do and how to begin to solve my phone problem.

Why this phone causing so many issues?
I'm was search how to fix this, but nothing doesn't work.
I have no idea what to do, and now I creating a new thread, maybe somebody can help.
Let's start.
I HAVE SECURITY ERROR when phone power on. After message disappear, screen goes down..
- No bootloader unlocked
- No rooted
- No usb debuging enabled
- No custom rom
- No custom recovery
This is the first time connecting with PC (Windows 10) and
- No driver (this is the most important issus)
I tried some drivers and installed but because phone only show error and go to shut down I don't know is this drivers working...
- Can't run fastboot
- Can't go to safe mode/recovery mode
- Can't do hard reset with hotkeys
The first thing is driver, while PC doesn't see phone I can do nothing.
Another important thing is that I cant do to safe mode. Without safe mode I cant do fastboot and flashing.
So maybe someone can help?
The Security Error means you installed an unsigned image on a device with a locked bootloader. You have to flash the original firmware following either this or this guide. You can get out of the security error by just flashing a signed recovery with fastboot, too.

I can't put phone in download mode. Doesn't work.
Nothing happening. Only show Security error on the screen.....
When connect with usb charger phone dones'n charge.
----------------------------------------
Put the phone in download mode:
Jellybean bootloader:
Turn off the phone, remove the battery. Put the battery in, hold volume up+down and plug in the USB cable, after 1 second of the USB cable being plugged in, let go of volume down, keep your finger on volume up until you see S/W Upgrade. If you see the LG logo you failed, repeat the step again.
ICS bootloader:
Hold Volume up + down while plugging in the USB cable is the method I think.
--------------------------------------
Volume up OR down, I always forget that.
After a failed attempt to invoke DL mode and switching phone off(hard reset usually), toggling the phone's power once increases the chance for success next time. Same as taking the battery out each time.
After the restore of the stock rom phone should reboot. If it shows the stock recovery's screen instead, phone will be instable later and might brick when trying to root it. Then repeat the flash process and it should boot now.
Just remove the battery, put it again, then hold Vol UP and while doing that plug in the USB. You're now in Download mode.
Hi, This guide is made for flashing Alcatel OneTouch POP UP (6044D). This won't work on any other device. This guide is very simple. If your device has been soft BRICKED or Hard BRICKED this is the way to restore it.
THE FIRMWARE PROVIDED IN THIS THREAD DEOS NOT BELONG TO ME
I AM NOT RESPONSABLE OF ANY DAMAGE CAUSED TO YOUR DEVICE BECAUSE OF THIS GUIDE, DO NOT TELL ME THAT YOUR DEVICE HAS BEEN BRICKED
What you will need
1: PC/ Laptop
2: Miracle Box (Link given down the thread)
3: Qualcomm Drivers
4: The Device
And some knowledge
So Let's start.
Link for Firmware:
https://drive.google.com/file/d/0ByQqd_psFzvxSEJ1OUpxSFFtRW8/view
Link for Miracle Box:
Link will be available tomorrow
First download QUALCOMM drivers, it's very essential or your PC won't detect it.
Download Miracle box (PROVIDED in the THREAD). The miracle Box has been cracked so it does not need a dongle. Make sure to turn off the antivirus otherwise the Antivirus will delete it:crying:
Download the FIRMWARE of the device, I have tried other Firmware with different tools but this was the only one that worked, my device was also Hard BRICKED, so the FIRMWARE is tested. Also I have tried other guides provided online but neither of them worked for me, Flashing it with QFIL Will lead to an error or an Unfinished flash.
When everything is installed.
[PHOTOS ARE INCLUDED ONE THE BOTTOM OF THE THREAD]
Open Miracle Box, Click on QUALCOMM, Then on Flashing, There you will see two option "Write Flash" and "Custom Flasher", so Click on "custom Flasher". Then choose "File to Write".
Also choose Partion(s) that you want to Flash. e.g. System.img so choose system as Partion and system.img as file to Write.
Once all of this is done, boot the device into edl mode, yes, 6044D has edl mode.
HOW TO
So to boot into edl there are two ways to boot into it. First is through recovery mode (stock) or TWRP etc... So if you have a recovery then navigate to reboot to bootloader in recovery, when pressing power button to choose it, press volume + and - at the same time start pressing home button two to three time. and then will turn dark black or back with backlight turned on.
This one is for without recovery, in case you don't have a recovery then, press power, volume + - and home button at the same time, the phone will start and will show boot logo, keep pressing it till it restarts, (When restarting press the home button multiple time) and it will go in edl.
(But in my case, I had to do it multiple time to get to edl mode)
Back to PC. Plug the USB to the device and the PC then Press port button, if it doesn't detect it, it means that it's not in edl mode, try again
When all is set press start, ( everything said on the upper paragraph must be done quickly or it will give an error ) so be quick:good:
Once the partition is flashed, do the same one by one with the whole rom, mainly system, boot, recovery etc... (When doing it you don't need to reboot and come back in edl mode)
WHEN FLASHING DO NOT REMOVE THE USB PORT! OR IT WILL LEAD TO EVEN WORSE CONDITION, JUST DON'T
Reboot and enjoy!
If you have any problems or questions ask me, give a thanks, that keep me motivated:silly:
Some stock rom screenshots are attached,
Another thing is that of you have a custom recovery for Alcatel pop up 6044D, like TWRP, CWM or Philz recovery, so please send it to me
I've been trying to install TWRP on my phone (SM-A105F)
I've done rooting it
I flashed it through the TWRP app in the play store.
I tried to backup my recovery in case of emergency
As I tried to flash it which is successful, I power off my device to go to my recovery mode which I assume is now TWRP
To my surprise, this leads me to boot looping my phone. I tried to disconnect my battery hoping it can end the loop but it doesn't.
I was hoping to flash my backup recovery but I can't access the download mode.
What am I supposed to do
Edit: Nobody is answering so I decided to embark on my journey on my own. And in doing so I was able to learn the ways to unblock my device.
The goal is to go to download mode of your phone as soon as possible.
It's easy, just press volume up and power off while an USB is plugged in your computer. This will lead you to download mode of SM-A105F. (Works even if bootlooping)
After that, download your device's firmware (AP,CSC etc).
Once you download, flash them all in ODIN. AP= AP , BL=BL and so on.(I guess you have the brain to figure this out, unlucky for me I didn't figure this right away)
Just wait and boom! New device, new firmware.
ALTERNATE:
If your ODIN isn't working, just restart your phone to download mode and try again.
I'm having a similar issue on an A10s, bootloop and can't enter download mode. the PC isn't even staying connected to the phone. it's like a 1 second connect then disconnects in an infinite loop.
Make Battery no charge.
Press : Vol_UP + Vol_Down and connect phone to PC by cabel.
Hold buttons until the phone displays The Download MODE.
