Long story short my V521 is bricked, as far as I can tell.
Here’s what happens:
Turn on.
Shows ‘can’t detect corruption’ unlocked boot loader screen.
Shows LG screen.
Reboots.
If I attempt factory reset via hardware buttons, I get a Nougat circle that says ‘Erasing...’, then reboots into the above loop.
Download mode seems to be nonexistent, as it just never works. My PC does not recognize it as the right device for LG support tool or Uppercut to find it, despite all drivers being installed.
ADB was working until stock recovery flashing (which I thought was gonna be a fix...)
And now I don’t know what to do.
Basically, the only thing I have is an unlocked bootloader.
Someone. Please.
Help me.

Try:
1. disconnect usb cable and power down your device,
2. hold vol+ button and plug in usb cable
It should boot your device into download mode.

Hello,
I Was trying to install cyanogenmod on my LG Optimusl5 and I was quite succesfull. I saw the screen working like a charm and the phone seems to be running ok. But, after something about 1 minute, the phone boots. This happens all the time when the system starts.
Another information is that this started after I unblocked the phone and BEFORE I installed the cyanogenmod (in other words, this boot occurs even in official room).
So, I tried to recover my bootloader typing really fast the command described in this post (http://forum.xda-developers.com/showpost.php?p=38053729&postcount=1159): dd if=/sdcard/bootloader_backup.bin of=/dev/block/mmcblk0p5. But I made this after installed cyanogenmod.
When it restarted, the smartphone shows the following message:
"
Secure booting error!
Cause: boot certification verify
"
I tried some recovery options like volume down, power and (after) home button, volume up, power and home button, volume up and down, power and home button. Everyone of this actions redirected me for this screen.
I tried to use KDZ but it does not found my phone.
The question is: have I bricked my phoje? Can I recover it? Without jtag?
Thanks in advance.
Anyone?
I saw that my windows loaded a adb driver when I plug my e612 into usb: fastboot interface (Google USB ID).
But I`ve tried to use the lg recovery tool and adb and neither of them found the device.
Does anyone have any (any!!) ideia??
Well, I can acess fastboot, but don`t know what to do.
How do I flash the original room on my e612?
Thanks
Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
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.
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.
Hello dear all,
I have managed to brick my LG G5 like an Old Mill Brick.
My LG G5 (lg g5 h850 titan) does not boot. It comes with an error message as follows: Your device is corrupt. It cannot be trusted and will not boot.
What I already did to Unbrick:
Tried to unlock the OEM. No way from USB Debugging as I cannot go into OS.
Tried unlock the OEM from fastboot (remote: oem unlock is not allowed).
Tried to flash some things like (boot.img, system.img) even adb sideload stuff. Nothing works. I cannot flash anything because (flashing not allowed) because OEM is not unlocked, but cannot unlock the OEM because it is not allowed. WHAT in the brick do I have to do now?
Cause of the brick of the bricks:
The LG G5 was on LineageOS, all stable and solid. When a prompt appeared telling me that I have to update the OS. So I was like yeah ok whatever. BUT, it did from OTA. I also had a specific LineageOS APP for updating the OS. After some minutes (updating) I immediately panic and started worrying. BECAUSE, I knew what time it was (my device is dead). I wanted to turn my phone off but it was already in Recovery (TWRP). So I just hit cancel. BUT after booting up the LG G5 that corrupt device error appeared and I cannot manage to get rid of it.
Please I need your help! I also watched and tried (2+ hours) to manage to solve this via Google and different links and Unbrick guides but nothing happens. I cannot unlock the OEM because it is not allowed. I cannot flash anystuff because the OEM is not unlocked.
Update: So, there is no Recovery System present. No stock Recovery, No TWRP. And I think no OS either. So only thing that is present is the bootloader screen smh.
Can you still get to TWRP?

No If I hold the volume down button and Power and when the LG Logo appears I release the power off and press again nothing happens. It goes again into that error. I can go in bootloader but can't do anything with adb or fastboot.
I think TWRP is gone too :/
You should be able to get into download mode. Hold the volume up button with phone fully powered down. While you hold the volume up button insert the usb cable. Then you can flash the full system kdz with LGUP
