Hey all,
I restarted my phone yesterday and it was stuck in a boot loop for some reason. I tried to factory reset, but doing so still resulted in a boot loop. I then proceeded to attempt to flash stock, but the flash tool crashed while during the process. When I try to boot to download mode now, I get "Secure booting error, Error!: Boot Certifcation Verify". I know this also happens on the G2, and I know the process for fixing it. But when trying to use the same method with the G3, I can't access my filesystem from Linux. Any help? Thanks.

I was rooted before updating to lollipop, then tried to back dowk to KK with TOT and this happened, so I dont think I am rooted any more.
The better question is: do you have TWRP (custom recovery) installed? If you do, your phone can be fixed. If not, you are probably screwed.
Basically it sounds to me like your phone managed to flash the updated Android 5.0 bootloader but didn't update the LAF image (download mode). The old download mode doesn't work on the new bootloader, it gives the error you are experiencing.
Because you still have a LAF partition, and presumably a recovery partition (even if they are not working) you cannot access fastboot mode.
In other words, there may be no way to fix your situation.
As the hardware is fine there must be a method, but it might be something only LG can do.

I'm in the same situation now.
I was bumped with TWRP and CM12 installed. I wanted to unroot and go back to stock. Started a flash with LG flashing tool, but it was taking ages, so I unplugged the USB cable in the middle.
Now whenever I boot via either VolUp+USB or trying to get into a recovery I get secure boot error.
Is there a way to fix this ? Or do I need to send a phone to LG ?
This has happened to me today. Downgrading got stuck at 3%. LG Flash tool said to remove phone and plug back in. Any way to fix
Also, does anyone know if downgrading voids warranty or anything?

I didn't find a way to fix it, so I've just sent it to LG repair shop. They haven't yet looked at it so I don't know how much would it cost.
People just tell the service center that you were upgrading from KitKat to Lollipop when the problem happened
Evidence wise it support your claim since the OTA from KitKat to Lollipop overwrites the aboot, sbl, laf and recovery partitions and service center people ultimately cannot tell between failed OTA and a failed KDZ flash

Did you get an answer on the cost yet? I have the same problem, so I'm probably looking at the same resolution as you.

It was free for me, as it was on warranty.
solution for no download mode
Hi guys.
If you cant enter into download mode then you need to force your g3 in to qhsusb bulk mode by shorting the test point.
When you short battery must be removed.
After short your phone will be detected as qhsusb bulk mode.
Send me msg in pm for further help.
If u dont know the test point then let me know.

Hi! I just recently bricked my LG G3 D852, and I would really appreciate it if you could PM me and help me out here.
http://forum.xda-developers.com/showthread.php?t=2785089
Try this. This will revert to factory default, tons of bloatware included ?
Sent from my D855 running CloudyG3 2.3 with Gabriel5 kernel.
Don't forget to smash that thanks button if I, or someone else helps you, guys!
Hello together,
I have a very big problem with my G3. A few days ago i tried to install CM13 on it, I thought everyting was fine but later in night the phone frezze always. Then i would restore the backup, but i can´t. I got an error, but I cant remember what error..
Than I tried to wipe, I got errors again. i just want to take a photo, and it suddenly works...
But installing the rom takes very long. It stays at:
"Patching system image unconditionally..."
(sorry cant insert the image)
Sorry for the few informations and my bad English, but I hope for help
Thank you, and merry christmas!
--edit:
I updated twrp to 2.8.7.0 bevore I could whipe.
I used this to repair my phone:
http://open-freax.fr...ick-your-lg-g3/
I thought it was working.. But now it is broken again..
The phone worked very fine for one day. And today it freezed suddenly, then I pulled out the battery and tried to reboot. From this moment it stuck on the screen with the cm logo..
I can't wipe, it stuck.. Installing the Rom give an error..
The Rom which is installed is: cm-12.1-20151117-SNAPSHOT-YOG7DAO1K8-d855.zip
And the gaps: arm 5.1 nano 25 December 2015 from opengaps
Probably the guide I used was not the right one for my problem..
I hope that I haven't destroyed the good G3 :'(
Download a diffrent rom on pc put is on a flashdrive an on the go cable then flash it in twrp

Or kdz or tot method back to stock and start again
Flashing a different rom was impossible, too.
tot method gives always errors.
And with using the kdz method, stuck at the the firmware update screen, after retrying now I stuck at the LG logo...
bricked again :good:
Hi guys, I got a phone here that my friend tried to upgrade it by using another phone model's rom. because both phones are same chasis n spec, exactly same looking on hardware even though from different brand.
THE PHONE IS BRICKED, NO RESPOND TO ANY BUTTON AND CANT BOOT AT ALL. ( NO EVEN BOOTLOOP OR ANY SIGNAL/VIBRATE)
anyone here hv solution or experience to share with?
p.s. the phone are meitu 2 mk260 from china, the rom flashed is from micromax canvas selfie a255. both phones hv almost same chasis n exactly same spec. MTK based. flashed using scatter loading method with sp flash tool.
Hi, is it possible for you to boot to recovery mode or bootloader mode? Also have you tried connecting it to a PC and seeing if it was detected?
As far as my experience goes, if you have a custom recovery installed and boot to it through a key combo (usually holding volume down and the power button) you can fix it from recovery. If you can boot up to the bootloader you could use fastboot commands to flash a custom recovery and fix it that way. Hope you're able to find a fix to your problem, good luck!
Hi,
So today suddenly my phone restarted and after that it was stuck on the micromax logo, I coudnt get into recovery either. So I tried to flash the stock kitkat rom using sp tools, it did manage to flash it the first time but the phone after that wont start at all, nothing not even the charging screen.
Is it bricked for good? I tried to flash it again but if I choose firmware upgrade or download+firmware upgrade in sp tools I get the pmt info error. Is there any way to get the phone back to a working state? Any help would be much apprecited.
Note: I did look through the old post on the similar topic where the guy managed to solve the problem by using a latest version of sp tools, Im already using the latest version , no dice.
Did you get anywhere with this to unbrick the device as I have similar with a GDP XP and it wont now boot or show charge its just dead!
Any help on fixing this would be great as we cant be alone with this. ATB
I flashed official lg 6.0 software on my g3(without rooting) and after a month of normal use I got stuck in a bootloop. I can't go into safe mode, but can get into download mode. Is there any way that I can keep all my data and flash the same firmware again?

Same problem here. Got a new G3 from LG and back to the same point after 24h : bootloop again and again ! I really think there is a software issue with that phone.

I had to hard rest it and now it works normally, you just need to hold the power button and volume down button until you see the lg screen. Then let it go and press it again until you see recovery mode where you can wipe your phone and it will work just fine.

Then you have to choose refubris in lg up ..also use differen version of software for example if you have v30b then use v30c .....but you loose all your data.
