Stuck on bootloop after KDZ-ing bricked Optimus G (Canadian version)

Hi guys,
I have an E973 (Canadian version) and recently it got bricked. So I decided to restore to stock using KDZ files. Thing is, once the KDZ process ended I was stuck on a boot loop so I used wipe.bat but everytime I use that file, I end up with this screen.
I can still get in Download mode and Recovery though. If I turn the phone off, it will just restart and get stuck on the LG logo again.. i've tried doing the whole process again and again but it's not working..
HELP PLEASE. (((
Thanks!

how can I do a factory reset when I can't access to the phone itself? Can you please tell me the steps? I can only get in Download and recovery mod. Thanks!
Press and hold Volume Down Key + Power/Lock Key at the same time isn't doing anything..

Correct way is
Both volume keys pressed' than press power
You will get a fastboot kinda screen
Now press volume down twice
Now press power
USB cable should be un plugged
Also if this doesn't work, go to download mode and flash kdz again.

So, as you said, I turned off the phone, pressed on both volume keys THEN power button and it's not doing anything.. I've tried to flash Kdz multiple times before posting this topic.. I really don't know what to do..

When KDZ-ing, patience is a virtue.

Try just Volume Down and Power, not both volume keys. Or just google Optimus G hard reset.

Help getting into recovery

I installed Mahdi ROM after being at CM 11 and I wanted to go back to CM 11.
I did a full wipe and restored using a NANDROID backup and the device won't boot up.
I tried some key combinations and Adb fastboot recovery but couldn't manage to get it into recovery, how do I do that? thanks
EDIT:ADB worked. Please close thread or delete it
EDIT 2: ADB Doesn't work now!
WHAT SHOULD I DO?
EDIT 3: Nevermind, got it!
for anyone who is in the same sitation like me:
hold power + volume down key until the backlight goes off (after failed boot)
then:
hold power + volume down until the LG logo appears
release power key (DO NOT release volume down)!
then press the power key + volume up key so you're holding all three buttons. a factory reset screen should come up. press power twice (maybe 3 times? dont remember) and then you should have recovery

I don't get recovery....I get a factory reset. I am not sure if this is just deleting all data or is it really resetting the whole device to factory new?

Press yes and it gets you to TWRP or CWM, not factory reset. It is confusing

If I press the power button twice it wipes the tablet, I tried pressing it once and the tablet just restarted?
Can someone please tell me if I do a factory reset here does it even delete the TWRP? I want to send the tablet back. It was rooted and now it's not but I want to make sure that this factory reset takes it all the way back to stock.
I tried the LGMLauncher but after downloading and unpacking the software it stops and tells me it can't connect to the server?

Tried the LG tool?

I did try the LG tool. It downloads the software and then unpacks it and then stops saying the there is no connection to the server. That's as far as it will go. I installed the LG drives but this has happened 4 times with no difference. I know some people are using this tool but it just won't work for me?

Can you try a different computer? It seems to be the only way to come back to perfect stock condition

[Q] How to enter recovery mode using key combination?

I can use "adb reboot recovery" to enter TWRP 2.7 recovery mode, but I want to use key combination, please tell me how to that.

Hold Power + Vol Down > Wait until LG Logo pops up and release from both buttons > quickly hold Power + Vol Up + Vol Down again
It will pop up with some message about reset to factory settings, but it's all a bluff.
Hit Power x3 times to confirm and you'll get to TWRP recovery

Thanks, it works.
actually I enter this factory reset mode before, but i just don't know it a "fake".

so will this erase all data or not?

That will depend on whether you've installed TWRP or not.
If you've still got the original recovery it will wipe it like it says it will, if you've got a custom recovery it will take you to it.
The standard recovery isn't a recovery like you're expecting it to be, if just has a way of resetting things to default without allowing you to do anything extra. OEM don't like giving people options but want a way to reset to defaults that the customer can use before needing to return a faulty unit which might not be faulty. If that makes sense.

Thought I'd lost recovery after flashing the lp rom. Sorry for the bump! Many thanks and lol at the 'bluff' factory reset!

From what I can tell, it's not a "bluff". It seems that the stock recovery partition would just automatically do a factory reset, so it warns you before booting the recovery partition. Seeing as you're non-stock, it just boots into TWRP/CWM. It's a valid warning that's simply set up in a weird way.

You don't.
We'll you might be able to but you're going about it the wrong way.
First you need to find the right forum for your device, then you read, followed by more reading.
At some point you've hopefully discovered that you should have done all this reading before you reset your device.
Also before pressing the post button on your next post, read it first to make sure it makes sense.

Thank you very much, I tried other combinations found on some web pages that failed. This one worked!

Issue remains.

I got myself in a pretty bad situation. I have the stock rom. I am trying to get that back using recovery but it's not working. Only factory reset screen. This tablet stopped working in 2015. It cannot write ANY data ANYWHERE. Can't take pics, Can't take screenshots, Can't download apps. Nothing. I really want my tablet back... :/

I'm probably not the best person to help, however if you put a new post up with more details on what you have access too, the community will be able to help out.

Install LG software on your computer first. Then with the tablet completely off, hold VolUp and plug the tablet into the computer. That will enter LG download mode. Use the LG software on your PC to install the latest firmware available for your device. From there you can use the guides on this forum to go custom if you so desire.

Somebody please help...

I have the h815 international version on MM, my bootloader is unlocked and is rooted
I flashed the xtreme music mod and after flashing it said to wipe dalvik/ cache so I did and then it was booting up but now it seems stuck on starting apps, I did a nandroid backup before flashing the mod but it won't let me boot into it by holding vol down and power and then releasing and pressing back in power, please please help me...

Super Edit: I held down power and volume down until the LG logo was present then let go and repressed the power button this will show a menu to factory reset the phone but if you click yes it will ask you again select yes again and it will boot into twrp (aslong as you've got it installed) now my phone is restored to its previous nandroid, thanks anyway XDA I know someone would of replied but I was becoming too impatient

Just power off the phone. Power it back on with pressing the volume button down and the power button at the same time, when the LG logo appears release the power button for a couple of seconds and press it again till you boot into the factory reset menu. Then you just have to select yes two times and then your phone will boot up TWRP Recovery. Don't be afraid of the factory reset menu, this is how the LG G4 boots into TWRP, it wont reset your phone. :good:
