Bricked Phone?

Yesterday I was backing up my phone through the third party recover screen when my phone shut off during the recover (I think I may have hit the power button?). Now when I try to start the phone when it's not plugged in I don't get any response from the phone. I can get to the fast boot screen but selecting recover mode just leads to a grey screen that says google on it for a second then the screen shuts off. I tried the LGNPST recovery method but the phone gets stuck in a loop at 67% where it shows the LG logo, the screen shuts off for a moment then back to the LG logo again. I've tried all the methods I can get my hands on, does anyone have any alternatives?
I thought I'd update this so that people that google their symptoms and come here have an answer.
I can't link to the youtube video but its called "Disconnect Battery LG Optimus G Sprint"
Pulling the battery fixed everything after installing the stock rom from LGNPST
Thanks to the folks in the IRC for help!

Lg g2 wont turn on

Im having trouble turning on my lg g2. My phone died last night and is unresponsive if I dont have it plugged in (like a normal dead phone) however, when it is plugged in the LG boot logo appears but then disappears after about 4 seconds followed by the red light blinking a couple of times and then the cycle repeats. I had my phone charging all night and i woke up to it still being in this cycle.
A couple of side notes:
I can enter download mode, although i am unsure if my computer is able to recognize the device
I am rooted
I cant enter recovery mode. the closest i have gotten is the "recovery mode screen.." then the phone powers off.
my device is an ls980 on sprint
Any help is appreciated and I am willing to factory reset as a last resort
did u find aby solution? as I am having same problem wont tun on or charge at all
If you can enter download mode, do it and see if the computer recognizes it. If it does then go ahead and flash the stock firmware using LG Flash Tool. If it doesn't install the LG drivers found on XDA.

is my G4 hard bricked ?

Well my G4 (VS986) has been running ok on 13b rooted since december 2015, and today it suddenly died, it was on my desk and when I tried to use it the screen was black and it won't turn on, something like this had happen before but I usually just remove the battery and voila it had it working again. But not this time.
Now It only goes to the LG screen and then it turns off again (but it doesn't bootloop) so I keep trying then I connected the phone to the charger and it tried to boot again and this time it went to a black screen saying Secure Booting Error and it was error code 1007 but it went off again.
Then I tried to access recovery mode and it can access and be there for 40 min and it wont turn off, however I can't put it on download mode alway when is connected to the PC it says "qhsusb_bulk"
Anyone have any idea on what happen and how to fix it.
Thanks.
Nevermind.. Say hello to a new bootlooping LG G4 !!
I put it on the freezer and after 20 minutes the phone boot up normal, but after a few minutes it went the famous boot loop.
Time for a new phone
