D802 v30a ERROR: Boot certification verify - Secure boot error - G2 Q&A, Help & Troubleshooting

Yesterday I flashed (CSE flash) v30a KDZ to recover my GPS which as having problems getting locks and it all went well, it seemed the GPS got back working.
Later I used the DP Root to root it and it went ok.
After using the DP REC (if required for evaluation, please inform), my phone rebooted and it showed me the following message:
ERROR : boot certification verify
[1040] ------------------------------------------
[1090]
[1140] Secure booting Error!
[1200] Cause : boot certification verify

Pressing the power button for more than 13s I can shut it down so that I can try the Volume Up + connect USB, but then it just powers the phone on and starts the above stated.
By pressing the Volume down + Power and pressing again after the LG Logo shows up, I can go to the reset screen but at the finish it doesn't show the factory reset or TWRP, just starts the sequence of screens above.
By pressing the Volume Up on the Demigod Crash screen, it show the following message:
Volume Up is pressed : Jump to Dload Mode.

and stays that way, but then the computer recognizes the "LGE AndroidNet USB Modem" and "LGE AndroidNet Serial Port", no more LG stuff there, and the LG Flash Tool doesn't go past 4%.
On Ubuntu it recognizes the same devices, but doesn't get the partitions
Does anyone know any way so that I can get out of this?

Hi @darknessmessiah,
Any luck with your issue? I've received a strikingly similar result after attempting to flash the stock lollipop to my LG G2 801 from the T-mobile forum.

Hi there! Yes, I got to get it back... But it was this hard
Anyway there goes some tips:
After you remove the battery plug, you only need to put it back after everything is done.
You have to keep trying the short circuit until you get a new hardware called "Qualcomm hs-diagnostics 9006" and you computer recognizes a lot of disk partitions. The normal device my computer recognized was "Qualcomm HS-USB QDLoader 9008" and no tip out there worked.
When the computer recognizes the wrong device, remove the USB, plug it back and try again. One time it recognized one whole 32GB partition, but thankfully I didn't try anything besides removing the USB and try again.
After everything, I got Download Mode back and, after some tries (I've got some errors), got the flashtool to flash the ROM back.

infect you need to fix the download mod
i can fix plz contact me https://www.facebook.com/faheem.anjum2

Wow, that's miserably complicated. And to show you my naivite, I wasn't aware that one could enter download mode by plugging in the phone to a computer with a USB cord, and holding the volume up button as it started up. My phone successfully entered download mode and I was able to use LG Flash Tool 2014 to return my phone to Stock 4.2.2 using this thread and a KDZ I had long ago stored.
Thanks for the help though!

[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!
Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

Nope, can't get into emergency mode, screen stays black, no matter what. So yeah, just flashing a new KDZ isn't an option. :crying:

Does the kdz flasher recognized the phone? If it's turn on and connected to the PC.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.
Thanks for the replies, guys!

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.
Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.
Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial

I no longer use this device, so I'm not aware if other users had the same issue like you.
First, did you try searching this forum for similar issues?
If not, it might be a better good place to start.
Second, please explain better whats happening to your phone:
Can you turn it on? If you can, what do you see?
Can you enter recovery mode? (volume down + home + power)
Can you enter emergency mode? (volume up + volume down + power)
Did you try flashing stock firmware with KDZ-flasher?
What ROM did you try to install? Did you check the ROM's page in these forum?

It's very problematic that you can't enter your device into emergency mode.
I think the only option that is left regarding software is to uninstall all of the drivers that are already installed for you device,
installing the latest drivers from the official site, and then try to use LG Mobile Support Tool to flash stock firmware.
Other than that you can only send it for a hardware repair

Hey,
When i say download mode i mean (Remove Back Cover and Battery>Plug in USB while pressing Volume Down Key!)
As far as i guess we can enter emergency mod by pressing both the volume keys and power key at the same time.
I tried using KDZ but at some point gives me an error of WParam and LParam as I posted above.

Yes, you're right - to enter emergency mode hold volume up + volume down + power
When you're inside you'll see on your screen "EMERGENCY MODE" on a yellow background.
Only the use KDZ-flasher or the lg mobile support tool.
If you're indeed in this mode, then try what @kien_vip suggested above.

Before entering emergency mode you should remove the battery for a few seconds. Place it back into your phone then enter into emergency mode. Hope this could help you.
Lg update tool uses baseband as the only check whether your device has the latest update. This means you will get the update if you use an older baseband. However, you should try emergency option.

I have lg optimus e400, first I flash ICS cyanogenmod then I return to stock ROM....then I discovered a kitkat update and I flash it but due to my vision issues again I returned to stock ROM, until I noticed really odd problem my system memory became smaller, 62MB to be specific, which is usually 125mb free space after a factory reset, I do the reset again and again using factory reset on settings and in the cwm recovery and nothing happens my installed apps is still there ,,other than that many apps stopped unexpectedly and doesn't work anymore (e.g. message, camera, gapps,WAP/mobile data,com.android etc)...
solution I tried:
-factory reset
-ROM reflashing
-clearing data and fix permissions via cwm recovery(this one fix the gapps and com.android force stopped)

[Q] Phone bricked, no download mode. Please help.

Hello,
I've looked for solutions everywhere and have spent the last days trying to fix my phone but i can't find a solution. Here is my problem:
I bought a second hand phone, it was working fine however it had been rooted and was running on Cyanogen.
I therefore tried to revert this to a stock EU ROM I downloaded. I was able to do this through the LGMobile Support Tool.
However when the process completed, my phone was stuck in a reboot loop on the LG logo. So I went back to the LGMobile Support Tool and selected 'Upgrade Recovery'.
After completing this, my phone was still stuck on the loop, but now I'm unable to access download mode, or recovery mode.
My phone is detected in device manager as LGE AndroidNet USB Serial Port (COM4) and LGE AndroidNet USB Modem when plugged in.
I don't know what to do? Please help.
This is now resolved thanks to bender_007

[Q] LG G2 F320L got bricked, almost give up here [PLEASE HELP]

Okay, this is must be my first thread since I join this lovely forum.
So here is the deal, this is my previous phone that I gave to my sister not so long ago, she has this not-so-bright wise *ss who try to fix her G2.
Sadly, he flashed the wrong rom, this is LG F320L and I think he flashed with F320K (based on error message that I got from the LG Flash Tool when I try to fix it)
This is the story so far :
1. the first time i got it on my hand (after get wrong-flashed that is ) :
- the phone is cannot boot, it stucked on black screen with fastboot command, try to go to recovery but not working, keep going to fastboot screen
- but i can still go to download mode (if I press vol UP while connect it to my PC) but somehow my PC will not recognize it
2. So I browse so many tutorial here and I end up erase and then reflash the stock recovery via cmd fastboot command, I'm 100% sure that I flashed the correct stock recovery file
- the process kinda work, the phone is able to go to recovery screen now although still cannot boot to system
- i still can go to download mode but the PC still didn't recognize it
- however, now the phone is being recognize by my PC if i plug the phone (without pressing anything on the phone), but gave me error code on the MTP driver
3. So next step I try to flash it via kdz method, didn't work of course, since my download mode won't be recognize, and then i also try to flash it via TOT method, also fail (again)
Note : on TOT method I try to flash it while NOT on download mode, since it will not recognized, it gave me error message that i try to cross flash or something. It says that I try to flash F320K to F320L (hence I assume that my sister's boyfriend flashed the wrong rom and got bricked)
also please note that while i'm did this i already make sure that i change the port setting to port 41
So now i stucked here, without the working download mode that can be recognized by my PC i think i'm start to running out of option to fix this phone
Please point me to the right direction good people of xda, please, thank you in advance

Okay, so at this moment does the device try to mount quite a lot of partitions? Also does it give any errors on the screen if you power on without trying to boot to download mode or recovery? Ideally we want to see something along the lines of security error.

thanks for your reply, i really appreciate it
well, you're right, it does give me errors when i power on (without trying to go to download mode or recovery mode)
so when i power it on, it shows LG logo then the image goes like corrupt, at first it kinda like shaking then it went blur and last it disappearing, leave the screen into just blank screen.
but my PC recognize it on this moment, just the MTP driver that wasn't
about your first question i'm afraid i can't catch what that means

so when i power it on, it shows LG logo then the image goes like corrupt, at first it kinda like shaking then it went blur and last it disappearing, leave the screen into just blank screen.
but my PC recognize it on this moment, just the MTP driver that wasn't
about your first question i'm afraid i can't catch what that means

Hmmm. okay, so what does the pc recognize it as exactly in device manager? Also if you connect the device do you get several pop ups stating that the mounted device needs to be fixed? It's just that if the partitions are being mounted we can reflash them manually using DD commands with ubuntu.

Right, you need to follow this guide i think. Ensure your read it fully before you attempt anything. Now, the lollipop update apparently changed some partitions so I would flash the bumped twrp from the development section instead of the 2.6.3.2 version recommended. Then once you can boot into recovery flash the rom recommended in this post

it's just like the pict that i attached
about the pop ups, no.. i don't think i got those, the only pop ups that appear was the small notification on the bottom right panel that the drivers is being installed, and keep failing on the MTP driver, maybe that's why my PC can't recognizes it under the download mode

if you open disk management what does it say about the g2? also did you install the universal adb driver at any point? http://forum.xda-developers.com/showpost.php?p=51265001&postcount=30 here it states that installing the universial driver will show your device as a samsung.

Additional! this rom flash assumes you are on a d802 so if your not on a d802 the dont flash it!

okay, i just checked on disk management and it appear that my PC doesn't recognized the G2, what makes it weird, at the same time it recognizes the G2 on device manager on ports (COM & LPT) on port 41, about the adb yes, i do believe i did that long time ago, though i forgot what was my intention of doing so

Hmmm. im stumped. I think its a bit of a catch 22 here. What i think has happened is that the rom flash that was done has changed some of the partition layout, but the methods of fixing that issue is either with DD commands from a custom recovery (which you dont have and cannot flash) or with DD commands using ubuntu when the device is auto-mounting all of your partitions. Its worth a look if you have an ubuntu disk around, if not download here, burn to disk or mount it to a bootable usb and see if ubuntu has any luck with it. Either that or try installing any drivers you can on the pc to get download mode working.
there is also this as a last resort but i've never had to do this so i cannot vouch for it :-/ Good luck pal.

Brother I had the same problem yesterday and the pc didnt even detect the lg g2.... The thing is just do like I did listen carefully.
1 / Download LGMobile Support tool and install it quickly
2/ Open that program and click on install drivers ( when drivers are installed just go to the right top corner you will find an " OPTION ' click on it >>> And then click on upgrade recovery and do the process it says until it downloads and finishes )
3/ Go to the phone and enter Dload mode by pressing one the volume UP button and plug the usb cable directly to your device
4/ When the process will be finished you will have your phone healthy ))) and please do not unplug the lg g2 during the process
