Hello all.
This guide will help you if you have:
A phone that will not turn on unless you plug it in and even then only an LG sign shows up followed by either blank/ rapidly flashing red light.
to my knowledge, what happened to put the phone in this state is the battery died while you were flashing a rom or something as such and the phone got confused on if it should be in charge mode or not.
being that the phone has a sealed battery, it is not as easy to pull out the battery as it is on other phones.
Fortunately for us, it is not difficult at all to unplug the battery!
REQ: torx screw driver that will fit but NOT STRIP the screws at the bottom of the phone.
Small phillips screw driver.
**I suggest charging the phone for a good 10 minutes before starting this. just to make sure it has a charge.
Step 1: unscrew the two screws at the bottom of the phone CAREFULLY!
Step 2: with your nails carefully pry up the back cover (inspect the phone carefully and identify the back cover from the rest of the phone.) off starting from the bottom of the phone.
Step 3: peel back the blue tape on the connector and remove the two screws.
Step 4: carefully pry up the connector from the top.
Step 5: plug back in and try powering on. By this point you should know if it worked and you can start putting the phone back together.
This guide is not the best (My first) but if you have any questions send me a message.
Good luck with your phones!
One of the first official LGOG teardown! Looks easier than expected..
@exemplarmusik sent from his LG - E970 ya dig?!
Awesome job, man. should come in handy for me at some point I am sure. I am curious though, those internals look identical to the Nexus 4's (as I guess we should expect) and I know the battery is glued down with the Nexus 4, so is that the case with our LGOG as well?
Yeah. The battery is glued in. I dont see an issue replacing it though. maybe a heat gun to losen up the glue and you should be good.
And yeah, it is very easy to open up.
This would have helped me last week. Oh well, got a replacement device and a free LG headset for my trouble.

I think it would only say that if unlocked, then you have N4 bootloaders.
I had this fast flashing "brick"-like issue, but after I let my phone cool, I just held power and vol-up and my phone went straight to the boot loader.

Damn, I didn't think it'd be that easy to take it apart. I wonder if it'd be possible to stick a Qi wireless charger pad in there, like the Nexus 4.
First of all, thanks for the guide. :good:
Here is what caused this to happen on my phone:
(black screen, flashing red light)
With phone off and charger plugged in you should be able to press power for a couple of seconds and it will show the charging progress. When you unplug the charger and press power you should see nothing unless you hold it long enough to power up the phone. Problem was that no matter how long you waited after unplugging the charger you could press power and see the progress ::what::
That causes the battery to drain, completely if left alone for a couple of days resulting in, you guessed it, black screen and flashing red light. After leaving it plugged in for 4-5 hours it regained a full charge and was fine.
This did not occur when phone was on while charging. Needless to say, I exchanged the phone. Hope this helps.
Don't assume you have any other pictures
I was considering trying to steal the signal amplifier and the filter from this and put in n4 ... and chance you got any shots of those in the optimus g ?
I still cant get mine to turn on, I unhooked the battery, still nothing. I hold the power it goes to the lg screen then nothing. I can hold power and volume up and nothing happens. Does anybody have a idea, I want my phone back.
Thanks
HELP!
My phone somehow will not turn on or charge! I have tried multiple chargers and outlets, and my phone will not charge or get the red light signaling that it is... There is no damage to the phone other than a small crack done a couple months prior. This happened very suddenly, the phone just ran out of batteries then stopped charging... is it possible to find the same battery as this and replace it?? My phone company said LG would not accept it because of the small crack on the front screen corner. Any help would be very greatly appreciated, really dont have the money to buy a phone off contract...

My phone is same yours. you plug and unplug somes times untill red light flash then push power button. goodluck
Wow looks like there are connectors on the back to go to the inside of the back cover... I wonder if this is compatiable with the orbe!... if not it should be easy to use old Palm Touchstone parts to make it charge wirelessly.
I have the sprint version I am hoping it has the same connectors... You guys see the two prongs on the back cover adn the metal places they attach to??

Those prongs are for connecting to the antenna in the back cover, not a wireless charger.

I could use some help guys, if this thread isn't too old. I've searched high and low to the answer here and nothing is working. I've tried download mode, fastboot, recovery, reset, holding power down, plugging it in and unplugging it. I've pulled the plate off of the battery, tried LGNPST, drivers, etc. No go on anything.
The phone is still dead, and will not turn on. The best I've gotten is a solid red light after holding the power button for 15-20 seconds. Then after about 3-5 seconds it resumes flashing (alternating between the red light and the key buttons). If I continue holding the power button down it will repeat this, showing solid red and then reverting to flashing.
I can not get the screen to display anything, not even the charging animation, and none of my computers will even recognize the device. I've been messing with it all day and I'm stuck. If anyone can help me, at all, please do. I hate going to Sprint. Anything but that, please.

me too.
I was doing the LGNPST and it was stuck at 67% for 15 min so i unplugged and the phone did nothing so I turned it off from recovery and nothing. no power only the power flashes red for a few seconds after pressing.
I am out of town now but if I can get it to turn back on I will send it back since I just received it today.
Unfortunately, my phone is now completely unresponsive. I have had it plugged in to the original wall charger for over two hours and still no power. If i hold down the power button for about 15 seconds while plugged in the red light will blink once every second until i let go. However, if I unplug it and do the same the light will not come on. I'm about to disassemble my brick and see if the battery pull will help any.
Any success stories in detail would be appreciated. Plan B is to send it off to Mobiletechvideos.
Edit: Moving on to plan B....thanks.

I did this trick a couple weeks ago when my phone stopped responding. Could only get flashing light while plugged in, and no response when not plugged in. Eventually while plugged in I could get to the bootloader, but could not get to recovery. This fix worked for me, though it may not work for you. You will need a T5 torx (star) screwdriver. Good luck.

Hey Y'all,
I helped a friend of mine root his NT awhile back, and it was working fine for months. I showed him CM7 running off of the SD card and he liked it, so I set it up for him on Friday. I did a factory restore on the NT, and he reentered his BN account info. I then booted off the SD card and everything was working fine as I could tell.
He brought it to me this morning and it won't charge. The "n" is always green when plugged up to the wall and it never goes orange to indicate it is charging. But when I attempt to power it on, it is always displaying the low power message and says to plug in the charger.
What I have tried:
-I removed the SD card, and it still won't charge... (not that it would matter).
-I have 3 chargers and my own NT. When I plug a charger up to my NT it works fine and the "n" goes to orange. But when I plug the same charger into my friends NT, the "n" is green and I can't get past the low batter warning.
-I have had my friends NT connected to a wall charger for about 3 hours this morning and I still can't get it to boot.
Any ideas on what might be wrong and how to fix it?
Thanks for your time.
I found this thread and tried both of the suggestions and my friends NT still won't charge or boot.

The same thing happened to my wife's nook this evening. I think the battery is completely run down, but won't receive a charge for some reason. Her charger showed green also.
I tried, removing and reinserting the SD card and also holding power for 20 seconds. I finally was able to hold down the power and the N button down for about 20 seconds. This did the trick. It showed that the battery was too low to turn on. After about 10 minutes, it booted.
Hmm, I get the battery is too low to power on every time I hold down the power button and the "n" is always green on the charger.
strandedinar, did you have the power cord hooked up when you held the power button and "n" button down for 20 seconds?
So connecting the STOCK charger and the STOCK cable and leaving it alone for an hour or so isn't doing the trick? That's really the most that many of us have had to do... No "n" button needed either.

Yes. The nook was plugged in and the "n" was green. The Nook wouldn't power on - My wife was convinced it was my fault for rooting it...
I left it plugged in like that for 20 minutes, but nothing happened when I tried to start it. The charging light was green. I finally tried the power + N button trick and then I received the notice that the power was too low to turn on. This was the first time I received this message. After this, the color of the charging light changed from green to red/orange and I could tell that it was receiving the charge. After 10-15, it power on and has worked normally since.
I tried every thing I could think of and google and nothing worked. I took it to BandN yesterday. They thought it was a typical issue that they see a lot of, but after 3 folks at the store couldn't figure it out, they called 1800 support. Support said it was a bad usb port and swapped it out for a refurbished model.
I still think I could have fixed it, but after a couple of days my friend was getting antsy for it.
Thanks for all of the responses.

How did you do that? I was trying to hold the buttons and never got anything.
My NT has no juice to boot, but when I plug in a power cord (stock), plugged into stock power charger, it tries to boot up. Power indicator does turn orange, but then it runs out of power once it starts booting and turns off. After a few second it turns back on, and repeats same cycle again. It never boots to the point where it can actually sleep, seems that boot-up process takes more energy than charges could give it.
Try charging it from your computer. Just as suggestion not sure if it will help.

Hello Galets, did you manage to finally charge your Nook? I have the same problem as you have - when stock cable and charger are plugged in - device tries to boot and screen shows up but due to lack of power in accum it turns off and in a few seconds the cycle repeats.
I hardly understand - how it is possible that having mains power plugged it - there is not enough energy to charge and do other necessary things...
---------------
UPDATE: problem solved. In order to solve it, I had to disassemble the tablet and unplug the screen cord, then I put the power cable in, battery charged up for about an hour or so, then I plugged screen cord back in and turned it on without a problem. The down side of early charge attempts is that tablet decided that I had 10 failed boots and it reset my previously rooted device. Now I have fresh and clean stock 1.4.2 version.

how did you unplug the screen cord? I've looked up how to take apart the nook, but I'm not sure which one would the the screen cord. Did you follow a tutorial somewhere, or was it easy to figure out once you opened it up?

ACL3, check this link: http://www.ifixit.com/Guide/Installing+Nook+Tablet+Display/11148/1.
I did not really follow the guide. I was looking for first two bolts to unscrew. The rest was quite simple but challenging - i don't usually disassemble things.
I did not pull out any of the buttons or battery from where they are and simply unplugged their connectors too - you will see 3 small foam rubber black box-like pieces (in step 9 they only marked one of them). There are plastic connectors under foam rubber pieces.
Be careful not to short-circuit anything with metallic tools.
On the attached image I marked the screen connector. I unplugged it by gently hooking it with two small screwdrivers. When putting it back I gently pressed it until I heard a click. And make sure those small slots on connector match with corresponding ones on motherboard.
Also, when finishing assembly I ran into a small problem with corner flap (which covers sdcard) - it did not want to smoothly slide in and out. So, pull it off completely and after putting plastic cover in place and screwing last two bolts, put it back - some small help of small screwdriver will be needed.
Hope my explanation was helpful

thanks, looks cool. I've never taken anything apart before and I'm afraid of short circuiting something. I think I might try this.
Last night i fell asleep and my phone died all the way, and now when i plug it in all i get is a lg logo then it goes away and then a dark lit up screen. ive let it charge for awhile now and i still get nothing, i cant get into cwm either.. the phone is unlocked and rooted and im running the base rom. Any help would be greatly appreciated.
Happened to me... leave it on the charger at least 3 hours and check it. The battery completely drains when you unplug the charger if you charged with the phone off. gl
Edit: If it still won't work, turn phone on and plug in charger.

This happened to me too. I completely drained the battery and it kept going into a loop (black screen, LG logo, battery screen). I left it plugged in and off and let it boot up.
FYI
This has happened to several people. I have confirmed through testing, even exchanging my phone 2 days ago that this is an issue created when unlocking the bootloader. Rooting does not cause it. Once the bootloader is unlocked, you can not get around this by re-locking the bootloader.
The workaround is simple. Either leave your phone on while it is charging or if you charge with phone off, unplug your charger and hit the power button- you will still see the charge animation running- this is what causes the battery to drain. All you have to do is power up the phone at least to boot then it is ok to turn off. You can confirm it worked by touching the power button again and not see the charge animation. Hope this helps.
Wow thanks so much for the reply and help! I've got it working now and I guess I'll just avoid it by not letting it die lol
Sent from my LG-E970 using xda app-developers app
well...
If you let it die all the way, its not a big deal. Plug it in, hold down the volume down button and the power button for 15 seconds, then it will work fine.
Threads like this makes this forum so great. Another potential problem to be avoided when using the phone.

Tonight my 4GLTE was plugged into it's charging cord and was at about 95% battery. I received a phone call, picked up the phone and pushed "answer". When I did the phone turned off and it won't turn back on. I've tried the "on & down volume" many times and nothing will happen. When I plug the power cord in the charging light isn't coming on.
I have had no problems with the phone. I'm on the Tranquility ROM and everything has been perfect. When I went through the S-off process back in Dec. the phone "bricked", it acted exactly like the phone is now, will not turn on, no lights come on, nothing. The great people at Dirty Racun walked me step by step through their procedure to unbrick the phone and it started up and has been perfect from Dec. til tonight.
I'm baffled and wish like hell this phone had a battery I could pull. Any suggestions will be appreciated.
thanks,

I take it the capacitive lights don't light up when you hold the power button down for several seconds?
Leave it plugged in overnight and try to power it on in the morning.

I know is very frustating cause It's happened to me as well.
I did some searching and found some tips. Nothing solid.
Leave the phone charging even though the led doesn't turn one. Sometimes for me it will revive after a while being plugged.
Other is to hold the power button for a very long time. 1-2 minutes and hope it reboots.

Nothing lights up, that's why I described it as being dead. I'm not a novice with these phones as far as rooting and installing ROMs etc. One item I left out last night is that in the last few weeks I've had to "move" the micro usb connector around to get the charge light to come on. It would always light up and charge but had probably gotten worse, not better. Also I have my Evo4G (which I just activated so I have a phone) and with this charge cord I also have to move it around to get it to activate the charging light. I'm going to buy a fresh micro usb cord this morning in the hope that the new cord will make a difference.
I'm really not optimistic that a new cord will change anything. I declined to buy the insurance for the phone when I got it in Dec. I;ve had bad experiences with Sprint and their cost to repair the Evo4G even with the insurance. I think I'm going to install Unix on my netbook again and try the procedure that Dirty Racun walked me through when the phone "bricked" last Dec. They brought it back to life for me although this time I'm afraid it has something to do with the usb port causing the phone to shut off and die. As I said last night, the phone was charged to 95% when the call came in and I picked the phone up and it suddenly went black.
I love this phone and having to go back to the Evo4G is a real step backwards, plus I've got lots of data on the internal SD card of the LTE that I need. I'm in pulling my hair out mode now....thanks for the suggestions, if anyone thinks of anything else please let me know.

Went through this a few days ago. Battery was at 40% and i was playing CSR Racing from the market. Anyways, my phone got super hot so i ended the game and went back to my home screen....few seconds later screen went off and phone was unresponsive. Nothing i did could make it turn on again tried for a few hours. My sister has a evo lte as well so i took apart our phones and switched her battery in place of mine and voila it booted up. Didn't expect the battery to just go out like that.

That's interesting, my battery has been excellent. I do remember a few weeks ago it getting really hot while charging but it's been fine ever since. I've got the phone apart now. I needed to replace the glass screen and bought, what I thought, were replacement parts for the lcd-glass screen. I've just found out from a video that the lcd and glass screen come together as one part. I don't know if I can take the broken one off and install the new glass screen or if I have to buy the lcd and glass. I'm ticked off because the ebay seller claimed this is all I needed to replace a cracked screen OR an unresponsive LCD touchscreen. I'm glad I didn't pay much for the glass.
Thanks for the info about replacing the battery.

Update: I talked with a Sprint rep at a corporate store yesterday and he told me to bring the LTE in and he was certain HTC would fix/replace it under the 12 month warranty as long as there was no physical damage "not turning on could be blamed for". I told him damage didn't cause it to suddenly go black while plugged in at 95% charge when a call came in.
I'll have to replace my screen before taking it in although the truth is my screen had a crack in it for 2 months before this happened and had nothing to do with the phone bricking itself suddenly.
Any updates?
My wife's phone had this happen at a ridiculously inconvenient time.
Here's what to try:
1. Pseudo-Battery-Pull: Hold power button for 15 seconds, this will force the phone to shut down (if it works). Try powering back up. If nothing, then:
2. Hold Volume Up + Volume Down + Power for 2 MINUTES, and then release. That should reset the battery charge logic. (Note: this will only work at all if the phone is truly powered off) If that doesn't work:
3. Disassemble the phone, disconnect the battery. Wait 20 seconds and then reconnect the battery, and reassemble the phone.
Step 3 worked for me. Hope this helps somebody!
Thanks,
Josh

Thanks alot for the suggestions, I'll give them a try when I buy a new screen/lcd etc. and install it. Going back to my once loved Evo4G is such a step backwards I can't explain it.

1. power button light blinks and then screen comes on(blank) and light stops blinking.
2. when power button is pressed once, black and white battery charging indicator shows for a few seconds and then screen goes blank, power button light starts blinking again. this loops.

This exact thing happened to me about a month ago. Whats happening is your battery is basically dead/at 0% or 1%. When you try and charge it the phone gets hot so it's not gonna charge.
What i did was literally put the phone on ice. You gotta get a bowl big enough to put a bunch of ice in, then put some kind of layer over that. Like a bag or foil. Something to keep your phone from getting wet. Now sit your phone on top of the ice and plug it into the charger. The phone is gonna slow charge and it'll take a couple hours to charge 4 or 5%. Wait 3 hours while keeping it on ice/charging it. Then take it off the charger and it should turn on. Now put it back on the charger and it'll charge normally. Idk how much of this made sense to you, but this worked for me after trying many other things.
Thank you so much. you have helped revive a dead phone. I followed your instructions to the letter and after three and a half hours found the phone to have charged to 60%.
The ice really worked. The heat wasn't allowing it to charge.

I'm glad yours worked out but my case is a little different. One night I was playing games for hours and hours and while I had the charger connected so it wont die on me and when I started to notice that it's getting pretty hot, I put it down and its still charging and let it charge overnight. When I woke up the phone won't turn on anymore. When I hold the power for a long time it would start blinking but the screen won't turn on or anything and when I let go of the power button it will stop blinking, power + volume up or down combinations has not effect or whatsoever.
So I decided to connect it to my laptop thinking that maybe it got brick and I'll restore with LGNPST but it won't even recognize the phone, no matter what button combinations I make. So I was thinking maybe the battery was bad so I bought a new battery, removed the screws &cover but when I installed the new battery the damn thing still won't turn on. So now I'm thinking maybe it's the charging port, I have replaced the charging/mic module as well and went through all the trouble of disassembling the phone BUT IT STILL WON'T TURN ON!
I don't know if this method will work but it won't hurt I guess but considering I have replaced the battery already and the phone had already cooled-down since it's been days that I can't turn it on. ANYONE OUT THERE CAN SHED SOME LIGHT PLEASE!
farewell LOG
well for trying almost everything even to the point of replacing parts I guess it's time for me to say goodbye to my beloved LG Optimus G. It's sad coz this phone is pretty powerful and good looking too, I dont even think I've unlocked the full potential of this phone but it served pretty damn well and unfortunately I think it's out of warranty already since I've had it for almost 2 years now.
So Sayunara LGOG!

I could probably help with your problem too if it's not too late. This same thing happened to my mom's phone(She has the LG Optimus G as well) My first guess was to replace her motherboard. I ordered her another optimus g from EBay that had a cracked screen and cracked back for $40(make sure it's an unlocked phone). The internal hardware was all in working order. I simply replaced the motherboard in hers with the one from Ebay, and it worked. If you haven't gotten rid of the phone yet you could try this. I found a teardown guide on youtube that made it really easy to remember where to disconnect and reconnect everything to the motherboard. The only downside to this is it's basically a new phone and anything not stored on your sd card will be gone. It's like a factory reset.
hey mate, wow I didnt think anyone would reply to my post anymore.. thanks for replying, anyway no I havent gotten rid of it yet though I already got a Galaxy S5 if I can fix it soon I can still return the S5 coz right now I'm not happy with it coz of the locked bootloader.
I was actually thinking of doing that since I've already gone through all troubles of replacing the mic/charging port module so why not just continue experimenting on it. I will follow your advice but do you know anywhere or anyone else I can find just like the one you got?
Your advice is greatly appreciated, thanks
Hi there, XDA folks!
Mario here with some phone problems..
I have a CDMA Evo 3D running on the stock ROM.
The phone's charging cable was shorting out ever since I bought it (got it 2nd hand). I had to wiggle it in order to get the phone charging.
I gave it to my girlfriend to use it for taking pictures n whatnot while outside of town. She returned it kinda Rambo-ish; the front of the phone basically fell apart.. the front metal grill surrounding it, at least.
Phone worked fine, except for the cable shorting out even more. My laptop shut down every time that happened, so I'm quite sure that's not what caused the problem I'll be explaining later on in this thread.
So let's get to the point, shall we?
My phone was really low on battery, something within the range of 2-5%. I tried charging it, but the wires shorted out again and the laptop died on me.. again, and again, and again..
I couldn't really bother with fiddling around with it until it starts, so I just unplugged it and left it that way.
The phone sat for a few days, my (main) laptop broke, so I decided to give the good ol' Facebook Messenger a go.. sadly, the phone would not turn on or start charging.
I removed the shrink-like wrap around the wires of the USB cable, cut the bad parts and twisted the color-matching wires in order. Sadly, the phone would still not charge.
I tried with another (self-made) USB cable... no luck whatsoever. Just to clarify; the blue wire on the one the phone comes with is ground, right? If not that could of caused the problem, since I connected the blue wire on the mini-usb to the black one on a standard USB plug.
I tried juicing the phone up a tad bit by running 5V on the battery for 15 minutes or so.. didn't really bother going for more, since it's kinda hard to keep 2 wires pressed against the battery for more than that. The phone powered up, but the display did not. There was the low battery sound, volume keys were functional, vibrating feedback was okay.. hell, the phone even took a screenshot when I pressed power button + volume down!
Sadly, that didn't solve anything.. even turned on, it would not charge. The 15-minute charge is good for a minute of red blinking light and fancy glowing buttons, nothing more.
Is the phone dead, or should I give it a hour charge directly and see how that goes?
Thanks in advance to everyone who replies!
i think it'll be good if you buy a universal battery charger for phone. so you can charge your battery without plugged to the phone

I am looking for more opinions before I spend cash I don't have on chargers that may not work.
If you or someone else is positive about the display not working because of not enough battery juice, then I'll manually charge the battery for an hour, even though it's uncomfortable as hell to hold 2 wires on the pins for that long.
What's bugging me is that it's not charging once it has just enough juice to power up everything, no display either. I'd like to know if it's doing that, because the battery is too dead to actually start charging up via the phone and whether the display just doesn't work or there's not enough juice for it.
Edit; I bought a chinese charger that charges the battery directly (2pins). The display still does not work and the phone will still not charge via the cable. Could it be a bad cable (and a dead display..)? It seems like the phone itself is responsive - I unlock it, press the "search" button and when I type on the keyboard (that I don't see), it vibrates with every pressed key.
Also, I can hear it taking a screenshot and the volume down/up buttons seem to be working fine.

this is exactly what's been going on with my phone as of a few days ago.
checked the time while it was plugged in, unplugged it...screen froze.
hasn't turned back on since.
the buttons on bottom light up, though.
i can take calls, use my unlock pattern (it takes me a few tries now that i can't see anything) and press the search key for google now.
for all intents and purposes...phone's fully functional...except i can't see anything going on.
i brought my phone into a sprint corp store, they changed the top housing for me screen and all for free.
it was really nice.
but, that didn't change anything.
screen still doesn't change anything.
they said the board probably shorted on screen lead.
have you figured anything out?

Nope, I'm still in the same situation.
Does yours charge?
My phone isn't recognized by my laptop at all, so I'm guessing something is indeed fried. I don't have the appropriate screwdrivers to open it up and inspect the board, otherwise I'd open it up and check it out.
If you have Torx T5 & T3 screwdrivers you should give it a go - post some decent-res pics over here and I'll at least visually inspect it.
I genuinely don't feel like spending more money for tools n whatnot for a phone that may be permanently dead.. planning on getting a second-hand S4 anyways. Waiting on a student loan and smashing this phone to pieces as soon as I get the cash for a new one. Can try and help out for yours if you manage to open it, though. Could be something as simple as a dead resistor that shouldn't be too hard to replace.
I tried the hillbilly method and hit my phone a few times against a wooden bench, that didn't seem to fix it. Pretty positive something's fried, but I'm also guessing it isn't a viable component, having in mind the phone functions normally, even though the display & usb port don't work.. hell, my phone woke me up at 3AM today, 'cause the alarm went off, lol!
