Not entirely sure why this has happened but im getting secure boot errors when:
1. I just turn the phone on.
2. Vol up + USB
3. Vol down + power button to get to factory reset.
After that it is the usual black screen with blue and red lights.
I cant use any button shortcuts to get anywhere, is there a way I can get the pc to recognise the device from this state?
I have the same problem. Like and idiot I deleted boot.img, aboot.img and recovery.img and then I realized that I didn't have the backup done. So I disconnected my device from the PC and nothing happened. Just turned off. The weirdest thing is the pc recognize my LG as a "LG Android USB Device". And I can't enter in download/fastboot mode
Any suggestion?
Sailing in the same boat, any help will be great, have a very expensive brick with "secure boot certification" error.

Let's refer to this other thread so we don't duplicate the same scenario:

I tried to flash a kernel s-on from recovery and now my screen won't turn on. I can hear notifications and even took a call but I can't see anything on the screen. I have a nand backup but I am having trouble accessing bootloader or recovery. I was using Dirty Underground rom I believe so I'm not sure if USB debugging was enabled. I currently only have access to a Mac computer. When I hold down the power button the notification light keeps blinking and the phone stays on, when I hold down power + volume down nothing happens, and when I hold down power + volume up it just reboots briefly showing the splash screen with red text and bringing me back to my black/dark gray screen. If anyone could help me get my phone back to working order I would be extremely grateful. Thanks for reading my post

Hold Volume UP + Power button for 10seconds, device will boot then, then immediately press Volume DOWN + Power Button to enter Fastoot.
Connect phone to PC, open command prompt and change directory to adb folder. Type in fastboot erase cache then fastboot reboot to see if it helps. If it doesn't, repeat process to enter bootloader then go into recovery and reflash.
What Kernel did you try to flash? ElementalX?
If you have adb access then just plug in your phone and type "adb reboot recovery". Then restore your backup or push a working kernel to your phone to flash.

What did you flash, what error does it display, is it "secure boot error", which version of g3 do you have, can you access recovery, do you have TWRP...?

i used ioroot to root the g3 (D855), and i flash with twrp-2.8.0.0_d855-signed.img. Yes i believe it was the secure boot error. After that the notifications lights at the topped flashed blue and red i turn the device ofd to restart and it will not turn on i have tried both to get into the recovery menu (power+vol down) and download menu (power+vol up) neither of which is working.

Ok... Lets start with battery pull in and out.
Even if you do recive secure boot error for booting to the unbumped recovery you should be able to boot to the OS, try with that.
If this fails, do the battery pull again and lets try to get you to the download mode. The way you specified (power+vol down) is incorrect I belive. What you need to do is hold the volume button WITHOUT the power button which will be followed by connecting the device to the PC with installed LG drivers.
If that works you could flash stock files, follow the thread: http://forum.xda-developers.com/showthread.php?t=2785089
Check in device manager how is the phone detected what mode ...

Does it get into download mode? For this one get the battery out and wait 2 secs. Plug it back in. Be sure to have an USB Cable ready plugged in the back of the PC (NOT IN FRONT HUB and be sure to be the original Cable). Hold Volume UP and Plug the cable. Keep holding Volume UP until you see download. Tell me if you see the Firmware Update screen or it is a security error.
I've searched extensively about bricked P600's and found a few threads where it seems it's still possible to boot into 'download' mode (Home + Vol Dn + Pwr) and from there it's possible to flash TWRP or some kind of recovery.
Unfortunately after attempting a flash I don't even have the capability of booting into either recovery nor download. All I get when I power on the tablet is the Samsung bootsplash and then black, dead screen (backlight is on).
Going through the process to boot into download mode then plugging it into USB + ODIN doesn't show up as a COM device.
Am I hopelessly at a loss?

When you tried to get into download mode, do you see the samsung screen turn on and off??

Yes, it flashes on the screen for a second before going to black screen.
*Edit: I've found that the tablet now wants to stay 'on' all the time. Long-holding the power button turns it off but it will immediately turn on again. When it's on external power and just switched off, the battery charging animation starts (with the spinning circle) but doesn't go into the animated 'bubble' charging display - instead it goes into the typical black screen with backlight on.
Hi, it's my first time posting here as I was unable to find a solution looking at similar threads.
Anyways, I was trying to install another ROM on the G4 but I think I messed up deleted everything entirely and got bootlop and reboot. I'm not exactly sure what I was doing as I'm new to these things.
What leads me to believe that this is not a hardware issue (as widely covered) is that during the bootloop, there's a tiny little green android in the middle of the screen with a small 3D box on belly.
When trying to solve this issue, I've tried:
Volume Up + Power to enter Download Mode
Nothing happens - back to the green droid
Volume Up + Power + USB to computer to enter Download Mode
Nothing happens - back to the green droid
Volume Up ONLY + USB to computer to enter Download Mode
Goes in Download Mode for a few seconds, but then goes back to the green droid
Volume Down + Power to enter Recovery Mode
Nothing happens - back to the green droid
Volume Down + Power to enter Hard Reset Mode
Allows me to factory reset, but then back to the green droid and bootloop
Connecting the G4 to the computer to see if phone would be available in device manager -
Not found
Nothing I've tried seems to shake off the little green android.
The phone doesn't connect to the computer at all.
Here's a video: youtu(dot)be/MfnkhZTPOz0
The top left of the G4 says "Bootloader State : Bootloader Unlocked!"
Here's a clearer image of the green android: android-hilfe(dot)de/attachments/2012-09-22-03-41-16-jpg.124036
Any suggestions?

From the thread you gave me it says 'YOU GET QHSUSB BULK MODE IN DEVICE MANAGER THEN INSTALL QUALCOMM DRIVER'.
But unfortunately, when I connect my G4 to the computer, it does not register 'QHSUSB_BULK'. In fact, it does nothing at all. The phone keeps rebooting and the computer does not detect.
So I cannot get either 'QUALCOMM HS-USB 9008' or 'QUALCOMM HS-USB 9006'.

So I have spent hours now looking around for an answer the phone is find my phone locked and I can't remember my pin code. I have done all the tricks with the combination keys.
The usual way to get into Recovery mode is Hold V+ and power until the phone vibrates and you should be in recovery mode release the keys. (Doesn't work)
Iv read that you should have the USB cable connected from pc/laptop while you do the same holding V+ and power button... (doesn't work ether)
and download mode should be very easy just hold V+ and V- plug USB cable from pc/laptop and you should get into download mode by pressing V+. Will only show charging Icon and that's its.
So is it possible to turn off this modes from the manufactor? Or is this a completely new security future? How can you use odin? How can you wipe the cache? If you end up having some issues.
Im going nuts....
No way to get into fastboot ether. So if anyone know why this is happening to me or got any solution I would appreciate it.
Plug in your cable with the phone turned on. Hit Power Off and wait for the phone to fully turn off. The charging logo will show up so let the animation do its thing. After maybe 20 seconds, press Volume up + Power and keep them pressed until you boot to recovery. If the command wasn't recorded in the first place and the phone is still off after more than 15 seconds, let go of the buttons and press them again and keep them pressed until it boots in Recovery

It will not work. How the hell should I be able to cle3ar cache if I got a boot loop ??? They can't just turn off recovery mode mand download mode??? This is so strange even paying for a frp reset but not even he does know what wrong??? Can they turn off fastboot, recovery mode and Download mode on this new phones? Is it because its locked with find my phone? 1 week researching now. It will only vibrate. And my PC cant find my phone anymore worked fine 30min ago nothing has changed... So annoying never seen this happened before every combination with buttons to get in any mode doesn't work only vibrates and go to pin lock screen...
Take it to a Samsung Experience center at best buy. Or send it into Samsung for repair.
download mode:
Turn off phone
plug cable in pc but not in phone
pres "volume +" and "volume -" in the same time
plug cable in phone
recovery mode:
plug cable in pc and s22
power off
press "volume +" and power
wait until see recovery mode

thats a solid advice assuming his bootloader/recovery/download mode is fully functional then this advice works, in his case and in mine too it does not work and trying to get to the root of the problem is the key. In my case recovery mode gives error on screen so it may have to do with the way firmware is installed as these modes are not accessible.
have you sorted it out? Its nearly a year onwards =)

This, at index 2:48 minutes.
It needs to be connected to the PC. Another screwy quirk Samsung added recently. Your button timing/sequence matters as well.
On my N10+'s you can go into recovery directly with a restart if you do it right. Otherwise they will puke on you.
