The message appears at the top of the screen above the LG logo after it has been there for a few seconds and it says:
I've tried Googling the error but every result is about a rooted phone and different models. It should also be noted that this started happening after a routine shutdown and restart command. The only apps I have installed that didn't come with the phone are Perk TV[1] .
The phone is otherwise a stock LG L34c from Tracphone.
I've seen a lot of posts from other users who encounter this issue after trying to root their phones or change software. Is there any chance of reloading firmware/OS/etc to surmount this issue?
Thank you so much!
Still no solution... If anyone can help, thanks
I have this problem also. I found the LG support tool in another thread, but it starts with the L35C model & doesn't seem work with this one

Hey everyone,
I know there are countless threads on this but I've been up all night going through pages and pages of info and trying virtually everything that each post said to no avail, so I thought I'd just make a new thread and see if anyone can help me.
Okay, so, I had a rooted L9, with locked bootloader, on stock JB before I started any of this. Yesterday, I decided that I wanted to put Cyanogenmod 11 on it, yet, I have only managed to soft brick it.
Basically, it's stuck at the Security Error screen. I can get it into the S/W upgrade mode, however, when I do that and open the LG support tool the program just crashes. The Windows "not responding" error pops up, and the program closes. I have no idea why this is happening now, because the program was working fine before, but anyways, yeah. I have the shttps thing running in the background, and the connection is successful. I tried doing the offline fix countless times, but no luck. I have the UpTestEX_mod2_marwin.exe file, too, that I've been trying to use, however, as you all know, it just opens the lg program when you click on "upgrade start" and the program crashes. I tried doing the software upgrade through the exe file, but it doesn't find the port. Device Manager tells me the L9 is on port 9, but it looks on port 1 or 0, and doesn't find the L9.
I think that's basically it, and, if anyone can help me at all it would be very much appreciated (I don't really want to have to buy a new phone!)
If it is a security error than I think it would be easier to fix it from omap4boot mode with unofficial fastboot. Its a thread in this forum.

I just got a new Lg G2 (Verizon) from insurance today and have been attempting to root it all day. At first I tried to the standard ioroot method, and as soon as the phone was supposed to enter stock recovery the Lg logo would show and the phone would then boot into the picture of an android with his chestplate open and a red triangle saying "no command". I tried several times. No change in results. I even tried factory resetting the phone. Same results (I am on 4.4.2 fyi). I couldn't find anybody else with a similar problem so I assumed maybe there was just an issue with my computer. So next I tried towelroot which many claim should work on all versions of the G2. When I click the "make ra1n" button it simply says "this device is not supported". Did they send me some new version of the G2 that for some reason isn't supported? Or has Lg implemented some software change to keep users from rooting? I have no idea what the problem could be. Any ideas what the issue could be/how I can fix it? I just want to install cyanogenmod
I keep getting a message on the LG startup screen, that says,
"secure booting error
cause: boot certification verify"
My phone was rooted using king root almost 6 months ago, and I had no problems with it. Until around a month ago, it started getting real slow and apps would randomly stop. So I decided to format the phone. There weren't many problems after that. but after a while it started getting slow again, but slower than the first time. One day almost every app closed and "LG Home" would close, it would give me some kind of error. I turned it off and tried turning it back on, but that's when I got that error. At first i thought my phone was bricked, i still sort of do, so I tried several methods. I can only turn the phone on in download mode, and my computer recognizes it as an android device.
At first I had some problems because i couldn't find my right .KDZ file, I used KDZ Update and I tried using LGFlash tool, but i can't find any of the files (.bin . dll) I need. I've also tried using the 2014 version of the LGFlash and used the LG Mobile Support tool, and nothing! They all take around 4 to 5 hours to finish!!! It never says there's an error or anything, none of them do! They always finish successfully, but the same thing keeps happening. Every time the phone reboots, it gets stuck on the LG logo and i get the secure booting Error!! What else can i try? Any suggestions? Am i missing something? All drivers are installed correctly and I've tried on windows 7, 8 and 10! Is there anybody who can help me? What do you think the problem could be? What causes the "secure booting Error!"??
So as the title states I bricked my LG G PAD X 8.0 while trying to root it and now it's on a bootloop with the message "Boot Verification Failed!!!" "-cause : MISMATCH_SIG_LEN."
I have searched and tried a few methods to no avail thus far. I cannot get it to start in download mode as it is not even registering on my computer. I have tried factory resetting via Power+Vol Down and then release Power and pressing it again but that has also failed and it's going back into bootloop.
I have tried using LGUP and LG flashtool but they are not detecting the device. I've looked into the BoardDiag method but they are not specifically for the GPAD. The method requires removing the battery and this G PAD either cannot remove the battery or it is very difficult to do so. It also requires shorting the pins but I'm not very sure where they are located on this device.
If anyone has resolved this or knows how to resolve please help me out. Alternative methods or expand further on how to properly perform the BoardDiag method would be greatly appreciated.
Input? Answers?

I just did the same thing. I skipped a few steps and now the x8.0 is in a soft loop!
Have you, or do you reading this have a solution yet? Looks like I will have to put this back in the box and place it in the back of a drawer!

I FOUND THE ANSWER TO MY OWN QUESTION!
I tried doing the physical button factory reset that the device manufacture suggested on its website but this did not work, located here LIBRARY HELP. But what did help was located under SOFTWARE &FIRMWARE PC SYNC that did help.
I followed a youtube video of this guy here: lgDOTcom/us/support-mobile/lg-V521 and through watching it about five times I copied the process "" and was able to get out of the soft brick loop process where the boot screen kept repeating the vibrate with boot failed message. This next video i didn't watch, but I scanned through it and it is the process that I went through step by step in fixing it. It took over five hours total but I when through the steps this person shows in this youtube video here youtubeDOTCom/watch?v=_tOtfF6gKkg
I will post my failed attempt on my youtube channel youtubeDOTcom/channel/UCeL3q6PUn7jV_VXTewIEppQ/playlists once I upload it later if anyone is interested in seeing how i went about bricking my tablet.
You definitely do not need to pop off the back and start soldering. One tutorial did that and it did not even work.
Your welcome !
Hello everyone, I have been a fan of your forums for quite a while, you guys have an awesome community. I have been attempting to unbrick my VS990 with no success, I have LGUP and all of the proper dll files in the proper folders, I have two .kdz. One is the stock kdz, I can not get to work at all due to anti roll back (no matter which option I choose) and the other is the current kdz. I got that one to accept using update, but it did not fix my phone, it is still stuck in boot loop. and using refurbish I get an error message saying that it is not supported by that kdz. LG UP is fully recognizing my phone, I found the .kdz files no problem, I believe that I have followed all of the steps here >> https://forum.xda-developers.com/lg-v10/general/guide-lg-v10-stock-firmware-to-stock-t3224170 any help at all would be appreciated. Side note, I have not rooted or installed a custom recovery.
I would also like to add, I can not do a hard reset. Every time I attempt the phone either locks up when I hit the power key on yes to confirm factory reset, or sometimes it reboots to LG splash screen and locks up then. I am starting to wonder if there isnt a hardware problem with the phone instead of software.
