Hi guys,
This day I flashed a new rom with my g3 (I went form Claudy 2.5 to Flumics 2.7). Flashing goes fast and without any problems, phone boots normal. Then I decided to look up a few things in the rom. I searched and found a point named devic hidden menu (I did not insert a nummber in the dialer). I clickt at it and get in the normal hidden menu. I read the textes there and found one interesting, i hope i rember it right, it was called devic test. So I clicked on it and then bad thinks started.
My phone rebooted, but in the start screen my phone stuck and in the upper right corner i can read:
Error: Boot certification vertify
Secure booting error
Cause: Boot certification vertify
Afer that the led started blinking red and blue.
I have Fastboot mode enabeled and I can get into Recovery (TWRP). So I tried to fix it with flashing my cloudy nandroid backup, wipe everything and to flash a "New" Flumics 2.5 Version, but it didn't worked.
I knew (and I read) Threads about topics like that, but im not sure if they can help, I need you're help guys! How can I fixs this, should I try to simply fash a stock rom?

It happens to me some days ago, I just flashed again the stock rom in download mode (KDZ file) and fixed.
Did you tried that method?

I´m not sure that he works, when I press volume up + power button and then connect it via usb to my pc my pc makes a noise like you´re plugging in a usb stick but I don´t see at the pc. On my phone I don´t get this "download mode information". When I go in TWRP and click on reboot "bootloader" I get into fastboot.
My issu is that I maked a device test, my phone rebootet an now it don´t boot any more, I just get to the lg logo and then I´m gettint this error. Then 2 or 4 sec later the led starts blinking and screen turns of.
This is my rom Flumics 2.7 . I thing it is based von V21c.
Wait, you can go to twrp ?
As for download mode, it's "hold volume up and connect", no power key..

Ok, I take it you're on d855. I'll make you a flashable to fix it. Have you try installing a rom via twrp instead of pulling backup ?

You are my hero when your flashable zip will work!
It's actually not flashable. You will have to run it on pc when phone is in fastboot mode.
download this and run it
you will have your download mode back and you can flash kdz/tot file or use lg mobile support tool

Hi, I have the same problem and I followed your instructions but while the new firmware is installing from the sd card, the phone shut down.
It seems like it has no sufficient power to finish the operation. In fact I tried to plug the phone to charge the battery and that don't work...at least the led is not on (but I'm pretty sure it's not charging).
After that the only things I can do is to power on again and see the boot loop.
Any idea on how to solve?
Thanks.

Since you can actually enter the recovery i suggest that you go in manually and try to reset/wipe and see if it starts.

Ok then last thing that i can suggest before you send it in for repair is that you download a diferent firmware (diferent update.app file) and try to flash that. If it fails again then send it.

Do you have acces to TWRP?? if answer is YES, then you can boot into it and use ADB commands on your computer to replace the file for the previous one.
If you can't use TWRP then you must use PC Suite and use recovery from error upgrades, this will flash your phone with your stock rom but won't gonna wipe your data so it's safe.
thanks guys! used the pc suit and solved the problem! thanks

I ran into the same issue. Phone is stuck in a bootloop. What is the process exactly? Since its in a bootloop my computer and my phone don't link. So I cant even get to factory reset. What do I do?

I ran into the same issue trying to increase my speaker volume and encountered a bootloop after a reboot.
I used LG PC Suite to recover but I was never able to connect properly, even with all LG USB drivers installed.
I resorted into flashing a stock firmware (10h) using the LG Flashtool and I was able to use my phone once more, but from a fresh install.
I will stay away from any sound mods until there is a permanent recovery I can install on my LG G3 D855

Try turning on your device on download mode before connecting to pc. You can follow pc suite or what @jtambis6 suggest. I recommend to try pc suite first.

Check your imei here and you have the lastest kdz for your G3 : http://lg-phone-firmware.com/index.php?firmware=1
You can just press vol down to reboot the phone normally. This happened to me until I decided I didn't like the error message and I flashed stock rom which was a b***h! Because the stock rom would flash the id get factory reset status 2 (soft bricked) Then I learned that the LG flash tool DOES NOT like USB 3.0! The thick and thin of it is just flash stock rom using USB 2.0
Hi,
I have problem with my LG G4 (H815). I has stacked at boot screen and sometimes it is able to boot to home screen but after a few second of work, it restarts again. Few days ago the situation was the same but after a few attempts it booted normally. I can normally enter recovery mode and download mode.
Has anyone idea what to do to recover data (photos) from it?
I will probably try to flash stock firmware via LG Tool but I don't know which version is now installed and I cannot find a proper kdz file.
Can anyone help to find a proper kdz file for this phone? and give a link to quide how to flash phone without wipe data?

o when you mentioned recovery i wasnt expecting the stock recovery.. so does your phone boot.? does it have the infamous bootloop when you see logo and it reboots again into a bootloop sometimes optimizing apps then reboots..?
if so i think the only way to recover data its to use the freezer method.. search for it... sorry
if its bootloop then its hardware and needs to be sent to LG just make sure the moisture strips arent allow to get losit or water.
is there any way to force bootloop???? with a kdz file or changing something with root permision ??? i need to send my phone to the SAT

You need to have an unlocked bootloader to do so.
What are the first 3 digits of your serial number (sticker behind battery)
If it starts with 5xx your chances are good to have the boot loop issue which is hardware related.
Try the freezer method to recover and send the device to LG for replacement.

Must get into "download mode" to kdz back to stock. Keep trying to get into "download mode" using vol. Up and good usb-c cable plugged into usb2 port running win10. May need to put phone in Ziploc freezer bag and in freezer to power phone completely off before getting into download mode
If you have access to TWRP flip over to command prompt (I think it's in advanced or settings) and see if you can use ADB commands to reboot into bootloader.
'adb reboot bootloader'
I've been in this exact situation before. H933

Press and hold vol down + power button. When the screen turns off quickly hold vol up and plug in the phone.
May require 2 people to do it in time.
