Hey guys wondering if anyone experienced the phone being basically bricked without actually unlocking, rooting or anything.
It has happened before one, just laying on the table and the phone turning off but it came back on after a while.
Today it occurred again but has not turned back on for two days. When charging the only light is the LED flashing constantly every second. If I hold the power button and volume up then the flashing of the LED changes pace to One long flash (1 sec) to two quicker flashing ones (.5 seconds). If I unplug it and plug the phone back, The LED flashing is back to the original constant pace.
When unplugged sometimes holding the power and volume up button initiates the LG logo and then turns off and then shows the logo once more and then turns off for good.
If I plug this into the computer, its like someone ejecting a usb and plugging it in like a maniac. I heard the connecting and disconnecting sounds from windows nonstop like as if its about to blow up.
I've tried holding the power button for a minute the same goes with different combinations with the volume buttons.
The only thing I haven't tried is opening the phone, kind of afraid I will mess it up. Any solutions?

Never heard of this but I can throw a few suggestions out. Try unplugging, then holding both Volume buttons and the power button (All three) for about 10 seconds. Try different USB ports.
Try this if all else fails: Source: http://cellphoneforums.net/lg/t348484-perform-master-hard-reset-lg-optimus-g.html#axzz2YPtvkfDk
To Perform a Master Reset via Hardware
1. Turn off your device.
2. With the device turned off, press and hold the Volume Down key as well as the Home key at the same time.
3. While both the Volume Down key and the Home key are held down, press the Power button.
4. When the LG logo appears, release all the keys.
5. Scroll to and highlight wipe data/factory reset by pressing the Volume Down key. Then press the Power button.
6. Scroll to and highlight Yes – delete all user data by pressing the Volume Down key. Then press the Power button.
7. As soon as the wipe has been completed, press the Volume Down key to scroll to and select wipe cache partition. Press the Power button when ready.
8. As soon as the wipe has been completed, press the Power button to select reboot system now.
9. The master reset should now be successfully completed and your LG Optimus G should restart.

Sent from my LG-E970 using xda app-developers app
I have no idea, when I plugged it in and check device manager, its constantly refreshing as its connecting and disconnecting the phone very fast. Is there another way to check

Anyways, doesnt matter guys thanks for trying, decided to just go in att and buy a samsung s4
i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

Problem solved just replace old power button and no problem! cost me less than 10 Euro
Guys , please help me...
The problem is that my power button has become way to sensitive and registers even the slightest pressure on it.
This causes the phone to lock up while using..
BUT THE REAL PROBLEM IS --> This causes the phone to reboot as the kay gets stuck in the pressed position ( long press of power button reboots the phone R8 ? )
please help me...
If you can suggest me how to disable the long press to reboot it would be really helpful..
even if you can point me as to which files are to be modified to reroute the function , I would get into it..
You cant disable it, it's done in hardware. The phone will reboot always if you keep pressed the power button, no matter if you are on recovery, download mode or normal mode.
The button must be replaced. Or you can try doing something like massage to the button by quickly pressing it hundreds of times with the battery off, for around 5-10 minutes, maybe it cleans the contacts a bit and the problem is solved.
You'll end tired, but luckly with a working phone. Or go to a repairing shop and tell them to replace the button.
Mine is also failing, for now it keeps going by pressing a lot of times when it fails, after a week or so it fails again. I'll replace it soon, no problem because I work repairing phones, it's not a hard or dangeours repair
Stock
It stays on a black screen unless i plug the charger in. I can then operate it for a while. But then all the sudden a message permanently stays on the screen saying "to restart your phone, press and hold the power button and volume up button for 10 seconds". also after this message appears the home button reacts by taking a screen shot (weird).
I have tried rebooting it and updating PRL check for software updates. Don't know what i should do.
I can't even boot into stock recovery because it won't power down it will just reboot. So i can't turn the phone completely off.
Anything i can try?
Try pushing your power button rapidly many times. It is probably stuck you may feel it... This has happened to me a couple of times. Maybe try some compressed air around it.
Ahhhh... Max Venom injection! Much better now...
So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?
try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.
Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation
So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.
glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.
