I think, your phone is hard bricked.
If at least phone turns on, you can try Rewriting IMEI process, then problem will be solved.
Take some developer's advice and confirm the device's problem will be solved or not.
If not, you have to go to LG service center.
You should NOT check erase entire (what it now is)

Hellow!
Today i have a Custom Rom to my Black.
But when i flash this, and press reboot in CWM the mobile turn of, and never never can turn on again.
I tried presisng vol. Up, but doesn't working.
Any ideas?
are you sure that ROM is for the Optimus Black? where did you get it from?
Is a SuperTeam ROM.
but in other way.. rom's can't kill mobiles...
Send me the link for the ROM.
http://db.tt/DNETBI5
No wonder it's not booting, you flashed a ROM that is not adjusted to P970.
I suggest you follow the repair tutorial (connect USB while holding volume up and without battery - you don't need the power button).
It should work. If it doesn't, well, you should go switch it at the store.
This rom is maked to p970! I'm SURE!
Other problem, for understand this.
Now when plug USB / AC to my black, doesn't appear battery caharging image, screen is black, and twho hours ago when y conect mobile(turned off) in screen apears a battery, but not now.
Now, you understrand more?

The ROM is made for P970 but it's not adjusted to it.
There's a difference.
Try this:

Isn't perfect, i know, but i don't know why when I flashed my p970 dies.
I tried ALL tutorials in XDA or other forums but the problems is.. that i can't turn on mobile in S/W Upgrade mode, you know?
I press and conect via USB but p970 do nothing!
It is very strange. Are you sure that you're doing it right? It is so easy.. Remove the battery, but don't insert it again. Without the battery you press vol up button and connect the computer to the device at the same time you press it.. You'll see s/w update screen
You thing that I'm idiot, no?
Sorry.. but i tried more than 20 times this combination.
Tried Vol. Down + Power too... and nothing works.
The only way is going to store, nah?
Yes I think you are. Someone that isn't able to just press vol up while connecting pc-lg without battery, that ask others to try a rom that bricked his own phone and that is talking about combinations and power when the only combination is vol up while connecting the device ... sorry but you'r not thinking right
Well try again.
Quit battery -> Done
Press Vol. Up + Conect to PC -> Done
What hapen? Nothing!
Do you have the lg mobile support tool and lg p970 drivers installed?
Okay, I cannot boot into s/w update and no battery charging indicator.
I haven't other solutions!
It's bricked mate, you have to switch it.
You don't have to have the battery out to do this.
I bricked my phone by accidently uninstalling the launcher without having another and i did this method with the battery in and it worked fine. You have to have the LG Mobile software installed though.
I accidentally uninstalled the launcher as well. And the phone is bricked. Did i happen to find a solution to that ?
So when I installed the TWRP app on the google play store and started it. It required me to rewrite my sd card or whatever so I went and ahead and did it. While my phone turned off still plugged into my computer via usb it started spamming the format windows on my computer. Like roughly 12 tabs opened up asking to format this drive. So I closed all the windows and re plugged in the usb and the same problem came up. And awhile all of this is going on the device is on but the screen is black and the back lights are on. Even when trying to restart the phone its the same problem stuck on black screen and the formatting windows keep popping up. It won't go to download or recovery mode it just stays on the black screen. This is my 2nd lg g2 I bought for business and I don't recall ever having this problem with my original LG G2. Anybody have any experience with this or a fix?

Yeah I've tried but the lg flash tool will give a error in the middle of flashing it
saying the phone is disconnected from pc, even though its still connected. It would go up to 25% then 60% then back to 25% in the middle of flashing then the error pops up.
Edit: Yeah while flashing the vs98024A kdz it will stop at 60% on the lg mobile support tool and it won't go past that. It'll just have the phone being disconnected from the computer error.
Is it safe to assume nobody knows how to fix this?
Same exact brick here.

Suggestion, have you tried the tot method yet? There isn't a 24A tot, but you can always take the ota.
same thing
I have the same thing and got it the same way with goomanager .was installing recovery and after reboot I got black screen with backlight on but to logo no nothing... can't get to download mode because I can't power off the phone. I also get the format drives promt in windows (about 15 or so all with a different drive letter) one drive I can read and it contains a folder called image with files in it. that drive is write protected. at this point I will wait till the backlight kills the battery and hope I can get into download mode after it shuts down.
FYI: I did try the LG mobile support tool but it did not see the phone. would love some ideas....

instead of waiting for the battery to drain, try this:
1. Unplug the phone from charger/USB cable
2. press and hold the power + volume down buttons for a few seconds... let go of the buttons 2 seconds after you feel it vibrate.
3. hold the volume up, and connect the phone to your computer.
you should be in Download mode by now....proceed to flash the phone back to stock using the LG Flash tool.
Hope this helps.
No Go

Well I tried steps 1-3 and no change. I have also tried this
http://forum.xda-developers.com/showthread.php?t=2582142
in Linux it seems to flash to the phone fine but I am still stuck with a black screen with the backlight on
I did wait for the phone to run down and shut off but still could not get into download mode.
My wife has the same phone .. is their a way to copy her working files to the bricked phone?
Windows see's the phone as QHSUSB_BULK in device manager if that helps any. before all this started it saw it as an android device
Okay so I'm a newbie to rooting. And I was on this step where I let the tool install some files to my phone and it said to unplug and pull battery, the next step said to hold power and - volume down button and release power when I see the LG logo while holding the - volume down after a second quickly hold power and - volume down to access factory data reset and settings. So it restored my phone back to factory settings and no root, the video said to try again but the problem is that my phone will power on anymore and is unresponsive when I charge it. So I took the battery out for a min. and the phone turned on but got stuck on LG logo and freezes then it shut off. I tried to boot it up again on LG logo screen, the corner it says Secure booting Error
Error code: 1009
MODIFIED!
And it froze and shut off. Now whenever I try to boot it up it gets stuck on LG screen and shuts off or when I'm in factory reset it freezes when I press yes. I put it into download mode and try to install the LG G4 stock kdz file but my computer couldn't connect with my phone for example, I plug my phone into the computer via USB but nothing, no sound and no charge now it won't turn on at all. I hope this wasn't too hard to understand and I'll greatly appreciate any kind of help, thank you.

I wonder if LG or T-mobile is pushing an anti-root tool that hard bricks the devices. My device was working fine until this morning after my alarm went off - Mind you, I have been rooted since the root came out. I unplugged the phone, put it in my pocket, and it got really hot, then it does the same as yours; except, my phone shows bootloader:unlocked when i try to reset it. So, yeah, you are hard bricked. No recovery from what I hear. U got a paper weight. I do not believe any of the G2 or G3 fixes will unbrick our devices. I think it may need a jtag.

I don't think I could do that, since my pc can't connect with my phone. I plug my phone via USB to my pc but there is no connection

My Lg L90 D410 is not booting up. Whenever I am putting the battery, the lg logo is coming automatically(without pressing the power button) and keeps on blinking. Cannot even switch off the device. Not able to go to the recovery mode. Can anyone help me?
I think I'm having the same problem! My d410 (with CM13), restarted from scratch and did not stop more, he calls on the logo of LG, off and back on again soon, this form of loop.
I could not access the recovery or the download mode, the solution was to arrange for assistance.
Factory reset it using the button combo (vol down + power). if you cant do that, enter the phone into download mode by holding vol up and plugging it into a PC, then flash a new stock ROM.
nothing is working... no one is here who can help me???
where are the experts..
LG logo blinking at boot looks like a hardware problem... You can try the fix hard unbrick tutorial before sending it to fix (probably replace the main board):
