I hope there is someone who can help me. I have purchased a used D802 on eBay. it was supposed to be in working condition but this is obviously not the case. When i turn it on the display just shows the following : Secure booting error Error: Boot Certification Verify!. If i plug it in to the PC it shows me a dozen of drives.
As if that wasn't bad enough i have no idea what was done to the phone so no idea where to start, don't even have proper drivers on the PC so PLEASE if someone could help me a bit i would really appreciate it.

Hey guys. I tried rooting my LG G4c but after rebootingen it seems that my phone is stuck in a loop, and i can't fix it.
What happens when i turn the phone on:
1. LG logo turn up
2. The following message appears:
[670] --------------------------------------
[670]
[670] Boot verification fail!!
[670] - cause : MISMATCH_SIG_LEN
[670]
[670] --------------------------------------
3. Phone reboots
Using the power button + volume down does NOT work anymore to start recovery mode (although starting the IMEI display still works).
I tried using LG UP to install the original firmware via USB but the device does not show up in the list (probably because the phone keeps rebooting itself). Some website also said to connect the phone with the pc, turn LG UP on, then put out the battery and put it back in to make it work, but that also didn't work.
Anyone know what i can try next? What method can i use to reinstall the firmware? And if it's not possible, does it cost much to repair and who should i ask?
Edit: It seems i can start "Factory data reset" but when this proces starts the phone restarts and continues the loop with the error message.
I also tried connecting the device with LG UP while the phone is stalled on the IMEI screen and the Factory data reset screen. This way the phone does note restart itself and it might appear in the device list of LG UP. But too bad it still didn't work.
I don't know if i'm reaching anyone who can help me, but even a answer from anyone saying that the problem is hard to deal with would already be very relieving I really can't find anything related to this problem on the internet and i'm noobish myself. I'm probably gonna visit a some phone shop down town in the next days because i really don't know what to do.

I had this problem too. I send it to LG and said the phone was unplugged during update process. They flashed it and I gave it to my mom. I have an S4 yet. Much better performance and rom support.
download mode

Can you get it into download mode?
Hi all, let me start by saying i apologise if this is the wrong section!!
I am running (sort of...) an lg g4 h815, rooted, but at the moment im stuck, so hoping to find info here
The phone at the moment is hard bricked and doesnt respond at all with/without battery, plugged into pc. No light, no download, and no recovery mode - litterally a brick..... i have opened up phone thinking that if i can get it to power up at all, i might be able to recover data or possibly even flash new files over to recover.
Pc dosent see it, not listed as adb device
What im asking really is, is there any way to just power up the internals so as its recognised my pc?? Even if that means connecting components on logicboard?
Any advice tutorial would be greatly appreciated as in its current state have not alot to loose
Xda has always come up trumps in the past
Thank you all on advance!
Good day all,
I've had my LG for a year almost working perfectly on stock OS. suddenly one morning it was battery drained and ever since wouldn't start up.
my LG boots and gets stuck on
ERROR : boot certification verify
[1040] ---------------------------------------
[1050]
[1050] secure booting Error!
[1050] cause : boot certification verify
[1050]
[1050]----------------------------------------
then it turns off alone...
i have tried getting it into download mode it gives me same error, have also tried a full hard reset(vol- power lg logo vol- power) it goes and starts with the android robot and loading then just goes off.
However i download the LG drivers and after i try turning on the phone normally it goes off all i did was keep holding the volume up button then plugged into PC(win7) i get a removable disk of 63.9mb with two folders init(image and verinfo), in device manager it is COM15 LGE AndroidNet USB Serial Port. please keep in mind the screen is blank off when all this shows on PC.
I'm basically out of options idk what to do, please help me i have searched all over the web and cant find anything valid .
Any help would be appreciated.

Pls help me
Hi guy,
I had a similar problem on weekend. I tried lot of methods and I fixed my phone. I don't have download mode yet, but i did my phone boot to system properly.
I don't know exactly what I did, my on forums of LG G3 a man posted 2 lines of comand that you can write on ADB. I think that these commands fixed my problem. But I tried lot of methods, so i can't say with conviction.
I will look on my historic on browser and put here all links that I researched.

See what i wrote above. There is a thread about this issue.
Hello everyone,
First of all, let me explain what had happened, my mom shut down her tablet before she went to bed and when she tried to turn it on the next day it showed a usb logo.
I cant access recovery mode, or any mode...
My computer doesnt read the drivers, well on windows 7 it doesnt read and windows 8 it says that it installed even though it didnt, its still unknown, anyways long story short I cant see the device in any program I tried.
The drivers name is moorefield.
I don't know what else to do, my mom is so sad and I really need to fix this, she loves her tablet. If someone can explain how to fix it, instead of giving me a link to a tutorial. because even when I followed other ones even on this website, the problem isnt exactly like mine.
The worst problem here is that I can't find it in the programs such as asus flash tool or xfstk downloader.
I really appreciate the help, thanks in advance!!!!
I have the same problem, hope someone can help us out....
